| typhoid colitis with massive lower gastrointestinal bleeding. an unexpected behavior of salmonella typhi. | three cases of salmonella colitis with massive lower gastrointestinal hemorrhage are presented. the patients had fever, diarrhea, and abundant hematochezia; blood and bone marrow cultures were positive for salmonella typhi. because of bleeding, all patients underwent hemicolectomy; previous mesenteric arteriograms showed the colonic hemorrhagic sites. the pathologic and radiologic findings are described. | 1986 | 3488182 |
| an international point source outbreak of typhoid fever: a european collaborative investigation. | a point source outbreak of salmonella typhi, degraded vi-strain 22, affecting 32 british visitors to kos, greece, in 1983 was attributed by a case-control study to the consumption of a salad at one hotel. this represents the first major outbreak of typhoid fever in which a salad has been identified as the vehicle. the source of the infection was probably a carrier in the hotel staff. the investigation demonstrates the importance of national surveillance, international cooperation, and epidemiolo ... | 1986 | 3488842 |
| iga-driven t cell-mediated anti-bacterial immunity in man after live oral ty 21a vaccine. | cellular immunity against salmonella typhi was observed by using a direct anti-bacterial in vitro assay in volunteers orally vaccinated with the live s. typhi mutant strain ty 21a. with this experimental approach, it was demonstrated that ty 21a vaccine also induces cellular immunity against s. paratyphi a and b. interestingly, the mechanism involved in cellular immunity against bacteria seems to be of an antibody-dependent cellular cytotoxicity (adcc) type, with iga acting as the humoral arm an ... | 1986 | 3489034 |
| pharmacological properties of droxicam, a new non-steroidal anti-inflammatory agent. | droxicam showed high antiinflammatory activity in carrageenin-induced edema in rat. at doses of 0.25 and 0.5 mg/kg, droxicam was as active as piroxicam and more active than phenylbutazone given at 2.5 and 5 mg/kg. against nystatin-induced edema, droxicam (ed50, p.o., 5, 6, 7, 8 h: 7.5, 12.9, 4.8, 8.4 mg/kg) was 4-11 times more active than phenylbutazone and more than 12 times more active than isoxicam. in cotton pellet-induced granuloma in rats, title compound was as active as suprofen. in u.v. ... | 1986 | 3489870 |
| sex-related differences in fever development of rats. | lipopolysaccharide (lps) or partially purified endogenous pyrogen (ep) was injected intravenously into rats of both sexes to induce fever. in lps fever, which was easily produced in 24-h dehydrated rats with an intravenous injection of lps, the female rats showed an attenuated febrile reaction as measured by both the maximum increase of rectal temperature (tre) and the thermal response index (ti). although castrated female rats showed the same magnitude of febrile reaction to that in normal fema ... | 1987 | 3492927 |
| salmonella typhi 205aty, a strain with two attenuating auxotrophic characters, for use in laboratory teaching. | the need for p-aminobenzoic acid of a previously reported pab mutant in a salmonella typhi strain causes loss of virulence (mouse median lethal dose by the intraperitoneal route with mucin, ca. 10(7) cfu, versus less than 200 cfu for related pab+ strains). this strain, however, gave p-aminobenzoic acid-independent revertants at a low frequency (ca. 4 x 10(-10) per bacterium per generation). it was therefore given, by transduction and mutation, a transposon-generated, nonreverting (rate, less tha ... | 1987 | 3493975 |

| identification of some interleukin-1 (il-1) sensitive organs in vivo using the induction of ornithine decarboxylase (odc) following injection of recombinant il-1 beta in mice. | intraperitoneal (i.p.) and intravenous (i.v.) injection of human recombinant interleukin-1 beta (ril-1 beta) in mice produced a 2-4 fold induction of ornithine decarboxylase (odc) in liver and heart six hours after administration. lymphoid organs (thymus and spleen) and brain did not respond to ril-1 beta administration with significant increases in odc. il-1-induced responses in heart seemed not to be secondary to stress induced catecholamine release since the beta-adrenergic antagonist propran ... | 1987 | 3501508 |
| [comparison of ampicillin, chloramphenicol and trimethoprim-sulfamethoxazole (tmp-smz) for the treatment of salmonella typhi infections in clinical practice]. | ninety-four patients with salmonella typhi infection hospitalized and treatment. widal test results, blood cultures, stool cultures and physical examination findings were admitted infection criteria. ampicillin used 100 mg/kg/day four divided dose in 52 patients, chloramphenicol used 2g/day four divided dose in 28 patients and tmp-smz 160-800 mg used bid in 14 patients. all of the treatments applied for 2 weeks. ampicillin 92.30%, chloramphenicol 82.15% and tmp-smz 85.71% were found success. fev ... | 1987 | 3502016 |
| [the effect of drugs on the immune response]. | in this study the effects of some drugs on the humoral and cellular immune responses were carried out. on the studying of laboratory animals, the humoral response by the antibody formation against s.typhi and the cellular response by ppd tuberculin of vaccinated animals with bcg, were examined. according to the experimental results, it was observed that trimethoprim/sulfamethoxazole (baktrim) and chloramphenicol did not effect humoral response but inhibited cellular response. it was determined t ... | 1987 | 3502284 |
| serodiagnosis of typhoid fever in paediatric patients by anti-lps elisa. | enzyme-linked immunosorbent assay (elisa) and immunoblot analysis showed that up to 50% of the anti-typhoid antibody in sera from blood culture positive paediatric typhoid fever patients is directed against lipopolysaccharide (lps) antigen. anti-salmonella typhi lps elisa was therefore compared to widal agglutination for serodiagnosis of typhoid fever in paediatric patients. sera from 38 paediatric control individuals were elisa negative for anti-s. typhi lps igg; all but 2 of these specimens we ... | 1987 | 3503403 |

| typhoid fever: successful therapy with cefoperazone. | we compared cefoperazone with chloramphenicol in a randomized trial involving the treatment of 25 children with severe typhoid fever. the clinical characteristics of the two treatment groups were comparable on entry into the study. four patients died (three receiving chloramphenicol, one cefoperazone), and an additional two patients received dexamethasone (one per group). excluding these six patients, the response of the cefoperazone group was comparable or superior to that of the chloramphenico ... | 1986 | 3511159 |
| salmonella focal intracranial infections: review of the world literature (1884-1984) and report of an unusual case. | focal intracranial infections are unusual manifestations of salmonellosis. forty-three such infections have been reported in the world literature. the clinical data for 34 well-documented cases are reviewed. eleven patients had brain abscess, 19 had subdural empyema, three had epidural abscess, and one had both subdural empyema and brain abscess. brain abscess occurred more often in adults; in contrast, subdural empyema presented more often in children. fever, signs and symptoms of increased int ... | 1986 | 3513285 |
| sensitivity of moore sewer swabs for isolating salmonella typhi. | moore swabs (sewer swabs) have been used successfully to culture pathogenic organisms from wastewater. sensitivity seems to depend on the size of the waterway sampled as well as the number of organisms present. in santiago, chile, we placed 24 swabs into the sewers draining the homes of 10 known chronic carriers of typhoid. swabs were positive for salmonella typhi in 5 of the 10 households (50%) and 6 of the 24 swabs placed (25%). | 1986 | 3513705 |
| the use of furoxone: a perspective. | acute infectious diarrhoea is a widespread cause of morbidity and mortality. some of the major diarrhoeal diseases are cholera, typhoid fever, shigellosis (bacillary dysentery), salmonellosis, "travellers' diarrhoea", and giardiasis these diseases can be avoided with proper education, sanitation, and hygiene. however, the majority of these diseases occur most frequently in areas of the world where political and social upheaval, poverty, overcrowding, and a lack of education prevail. although vac ... | 1986 | 3514312 |

| [treatment of typhoid fever using ofloxacin. clinical experience and determination of antibiotic diffusion into the mesenteric lymph nodes]. | nine patients with typhoid fever were given ofloxacin in a daily dosage of 400 mg for ten days. all patients recovered with no relapses. no case of salmonella typhi carriage was recorded. diffusion of ofloxacin into mesenteric lymph nodes was studied in four patients. mean concentration was 1.46 micrograms/g after four 200 mg doses. according to our results, ofloxacin could be considered as one of the alternatives for treating typhoid fever. | 1986 | 3534732 |
| [sensitivity to antibiotics of salmonella typhi and paratyphi strains isolated in algeria 1979-1984]. | outbreaks of typhoid fever due to multiresistant strains of s. typhi have occurred in some countries. monitoring of the susceptibility of s. typhi and paratyphi strains to antibiotics, especially those used to treat salmonella infections, is therefore essential. in this paper, we report the results of our study of strains isolated in algeria from 1979 through 1984. studied strains were isolated in our laboratory from stool or blood samples or sent to us for confirmation of the diagnosis. we used ... | 1986 | 3534753 |
| norfloxacin in the treatment of bacterial enteric infections. | diarrhoeal diseases are a major cause of illness and death among infants and young children, especially in developing countries. they are also the principal cause of illness in tourists who travel to these countries. overall, the main causes of diarrhoea are bacterial. campylobacter, enteropathogenic e. coli, shigella and enterotoxigenic e. coli are, in this order, the most common bacterial enteropathogens isolated in developing countries, and campylobacter and shigella in developed countries. e ... | 1986 | 3535054 |
| [microcalorimetric study of salmonella]. | we investigated the heat production of 42 different salmonella strains belonging to the serogroups a, b, c, d and e. using columbia- and brain heart infusion broth as growth media, we found 3 different types of heat profiles. salmonella typhi and salmonella choleraesuis showed thermograms which differed in shape from the remaining serotypes. the thermograms of one salmonella dublin isolate which showed an atypical biochemical behaviour could not be put into proper relation to one of these 3 micr ... | 1986 | 3541456 |
| [ultrastructural study of intestinal bacteria grown on endo- and levine-type nutrient media based on nonfood raw materials]. | the comparative electron-microscopic study of several test strains (salmonella typhi h-901, shigella flexneri la 8516, and escherichia coli 055) grown in experimental endo and levine media prepared on the basis of raw materials unsuitable for human consumption and in commonly used similar media prepared on the basis of sprat hydrolysate has shown the test strains grown in media containing aminopeptide and fodder yeast hydrolysate to retain their typical ultrastructure, which confirms the possibi ... | 1986 | 3541464 |
| the comparative activity of pefloxacin, enoxacin, ciprofloxacin and 13 other antimicrobial agents against enteropathogenic microorganisms. | in this study, we compared the activity of pefloxacin, enoxacin and ciprofloxacin against 269 enteropathogenic strains (campylobacter jejuni, enteropathogenic escherichia coli, salmonella typhi, shigella spp., vibrio cholerae and yersinia enterocolitica) with that of rosoxacin, flumequin, nifuroxazide, erythromycin, chloramphenicol, ampicillin, cefotaxime, tetracycline, amikacin, netilmicin, sulfamethoxazole, trimethoprim and co-trimoxazole. pefloxacin, enoxacin and ciprofloxacin were always amo ... | 1986 | 3546145 |
| [detection of microbial variants of salmonella typhi in the bone marrow of typhoid patients and carriers]. | the immunofluorescence test with the use of antisera to s. typhi and its l-forms permits the detection of the infective agent in bone marrow smears. this diagnostic method is particularly important in cases of carrier state in the latent phase and in differential diagnosis. as revealed in this study, the microbial variants of s. typhi, reacting with antiserum to its l-forms, are present in the bone marrow of carriers. they are localized, as a rule, on the membranes of lymphoid and erythroid cell ... | 1986 | 3548169 |
| evaluation of humoral and cellular immunity in patients with urinary tract infections. | the cellular and humoral immunity of 15 patients with recurrent urinary tract infections was assessed during infection. we determined the reactivity of peripheral blood lymphocytes to microbial antigens (ppd, streptolysin o, tetanus toxoid, salmonella typhi and escherichia coli), to allogenic cells, and to mitogens (phytohemagglutinin, concanavalin a, pokeweed mitogen and jacalin). t and b cells were counted by the rosette technique. we also evaluated serum immunoglobulins and c3 and c4 levels b ... | 1986 | 3548856 |
| failure to detect hydrogen-sulphide production in lactose/sucrose-fermenting enterobacteriaceae, using triple sugar iron agar. | triple sugar iron agar failed to detect hydrogen sulphide in 44 out of 69 hydrogen-sulphide producing strains of enterobacteriaceae, which at the same time fermented lactose and/or sucrose. the species involved were salmonella typhi, salmonella enteritidis, citrobacter freundii, escherichia coli, and proteus vulgaris. by contrast, no false-negative reactions were observed in 74 strains, which fermented neither lactose nor sucrose. failure to detect hydrogen sulphide was probably due to acidifica ... | 1987 | 3551500 |
| cytopathogenic effect of salmonella typhi gifu 10007 on m cells of murine ileal peyer's patches in ligated ileal loops: an ultrastructural study. | an electron microscopic study revealed that, within 30 min after inoculation into the ligated ileal loop of anesthetized mice, cells of salmonella typhi gifu 10007 adhered to the m cell surface of peyer's patch lymphoid follicle epithelium, and induced almost complete destruction of m cells. the m cell cytoplasms were pinched off and extruded from the epithelial lining into the luminal space together with the lymphoid cells primarily enfolded into the corresponding m cells. when two or more m ce ... | 1986 | 3553868 |

| acute autonomic neuropathy with salmonella typhi infection. a case report. | acute autonomic neuropathy is a well-described clinical entity that is easy to diagnose with appropriate bedside tests. this condition is described in a patient who had a concurrent salmonella typhi infection. the relationship between the two conditions is not entirely clear, but the simultaneous disappearance of the s. typhi from stool, the drop in widal titres and rather early recovery of the autonomic neuropathy tend to implicate s. typhi as the causative agent. | 1987 | 3563822 |
| [mitogenic action of bacterial t-independent antigens under various conditions of lymphocyte culture]. | the mitogenic response of lymphocytes in mouse spleen cell culture to the action of salmonella typhi lipopolysaccharide (lps) and vi-antigen under different experimental conditions has been studied. the density of the culture has been shown to influence the activation of lymphocytes with vi-antigen. thus, macrophages stimulate mitogenesis at the concentration of lymphocytes equal to 1.0-1.2 x 10(6) cells/ml and suppress it when this concentration increases tenfold. the method used for the purifi ... | 1987 | 3564784 |
| [sensitivity to chlorine-containing disinfectants of salmonella typhi strains with transmissible drug resistance]. | sensitivity of 201 s. typhi strains to antibiotics and chlorine containing disinfectants was studied. the strains were isolated in the regions of the left bank ukraine. among the typhoid cultures the proportion of r+ strains was on the whole equal to 29.3 per cent. chloramine resistant strains amounted to 21.8 per cent. among chloramine resistant strains the number of the cultures carrying r plasmids was 3 times higher than that of the strains sensitive to disinfectant. simultaneous transfer of ... | 1987 | 3566232 |
| role of splenic stroma in the action of bacterial lipopolysaccharides on radiation mortality: a study in mice carrying the slj allele. | slj/+ mice display a slight macrocytic anaemia due to a defect in their haemopoietic organ stroma. they have a deficient endogenous spleen colony (cfu-end) formation following sublethal doses of gamma-radiation compared with their normal +/+ littermates, which is likely to be due to the low pre-irradiation cfu-s content of the slj/+ spleen. cfu-s in these congenic mice do not differ in their sensitivity to gamma-irradiation or stem cell-activating factor. while injection of +/+ mice with 10 micr ... | 1987 | 3568089 |
| production of vi monoclonal antibodies and their application as diagnostic reagents. | serum antibodies to vi antigen were detected in mice immunized with the purified antigen but not with vi-bearing salmonella typhi whole cells. fusion of the spleen cells from one of the vi antibody-producing mice with nsi myeloma cells produced four stable hybridomas that secreted antibodies to vi. monoclonal antibodies from these four clones were all of the immunoglobulin g class and, as determined by competition, appeared to have the same epitope specificity. despite their immunoglobulin g nat ... | 1987 | 3571457 |
| invasiveness of salmonella typhi strains in hela s3 monolayer cells. | the internalization and intracellular multiplication, i.e., the invasiveness, of salmonella typhi strains recently isolated from typhoid fever patients were confirmed in hela cell monolayers. when stained with giemsa solution, intracellular bacteria were 0.6 x 1.2 micron in size and stained purple, whereas extracellular bacteria associated or not with the hela cell surface were 1.0 x 3.0 micron and stained deep blue. strain gifu 10007 was internalized into 23% of the hela cells within 10 min aft ... | 1986 | 3574155 |
| diagnosing enteric fever: a reappraisal. | the diagnostic value of 19 clinical and laboratory events was assessed in 150 enteric fever cases. a logistic regression analysis revealed only 8 predicitive variables for the presence or absence of enteric fever. these were, in order of importance, the white blood cell count, the s. typhi h agglutinin titre, body temperature, the s. typhi o agglutinin titre, the s. paratyphi a h agglutinin titre, the s. paratyphi b h agglutinin titre, age and the fever pattern. this study showed that objective ... | 1986 | 3576287 |
| the enhancing effect of exercise on the production of antibody to salmonella typhi in mice. | the effect of long-term regular and moderate exercise on antibody production has been studied in mice. healthy mice were trained to run for 10 min twice a day, and antibody levels following immunization were compared with those of healthy sedentary control mice. the antibody levels of the running mice were significantly higher than those of the sedentary animals at all times tested, from 1 to 13 wk post immunization. overall, the antibody titres of the runners were 2.76 times that of the control ... | 1987 | 3583317 |

| successful treatment of typhoid fever in children with parenteral ceftriaxone. | eight children, seriously ill with bacteriologically proven salmonella typhi septicemia, were successfully treated with a single daily intramuscular injection of 2 g ceftriaxone given for 5-7 days. all children improved clinically within 48 h of starting therapy and all except 1 became afebrile within 5 days. none relapsed during the 4-week follow-up study. | 1987 | 3672051 |
| platelet-activating factor: an endogenous mediator for bowel necrosis in endotoxemia. | we have developed a model of isochemic bowel necrosis in the rat by injecting platelet-activating factor (paf) or paf in combination with bacterial endotoxin. paf causes profound hypotension, and it has been suggested that it is released during endotoxin shock. because ischemic bowel necrosis is often associated with shock or infection, it is possible that paf is the endogenous mediator that causes shock and bowel necrosis during sepsis. in this study, we have demonstrated that: 1) normal intest ... | 1987 | 3678700 |

| presence of endotoxemia and its relationship to liver dysfunction in patients with typhoid fever. | twenty-one patients with typhoid fever were studied to evaluate the presence of endotoxin in peripheral blood and its relationship to the incidence and features of hepatic dysfunction which may occur during this disease. the limulus test for endotoxin was positive in the plasma samples of all patients prior to treatment. liver dysfunction, as assessed by fasting and postprandial serum bile acid levels and by standard biochemical tests, occurred in 90% of patients. in seven, the injury was purely ... | 1987 | 3692608 |
| [absence of the antigen h:z66 in 2355 strains of salmonella typhi from madagascar and several countries of tropical africa]. | the presence of the new flagellar antigen h:z66 (guinée, 1981) was investigated among 2,355 strains of s. typhi isolated from 1981 to 1985 in madagascar and some countries of tropical africa: burundi, ivory coast, gabon, mauritania, central african republic, rwanda, senegal, zaïre. a method based on the immobilization of motile strains in soft agar with immunserum anti-h:d, was used to detect strains carrying antigen h:z66. no african and malagazy strains had antigen h:z66, irrespective to their ... | 1986 | 3698151 |
| specific immunoglobulin-secreting human blood cells after peroral vaccination against salmonella typhi. | studies on intestinal immunity in animals have suggested that lymphocytes, after sensitization in peyer's patches and maturation in regional lymph nodes, home via the circulation to the intestinal wall, where they secrete antibodies into the lumen. to detect such homing cells in the blood of human volunteers given oral, attenuated salmonella typhi vaccine, we used the solid-phase enzyme-linked immunospot assay for s. typhi-specific antibody-secreting cells (ascs). ascs were found in eight of 10 ... | 1986 | 3701119 |
| lipid peroxidation by gamma-radiation in salmonella typhi membranes: the effect of ascorbic acid. | lipid peroxidation in isolated membranes of salmonella typhi occurred following gamma irradiation. the presence of the sensitizer, ascorbic acid, during irradiation resulted in a stimulation in the level of peroxidation. this enhancement of lipid damage could be prevented by the addition of the free radical scavenger sodium formate. catalase and superoxide dismutase appeared less effective in this respect. peroxidation in an unsaturated fatty acid and a phospholipid was also affected by gamma ra ... | 1986 | 3718525 |
