[bacteremia caused by non-typhoid salmonellas during an infection by the human immunodeficiency virus (hiv) in the african adult].infection caused by non-typhous salmonellae during the course of hiv infection is known since 1983. the authors report on 103 bacteremiae of this type found in one year. diagnosis has been based on hemocultures. 86 patients out of 103 were hiv+. all of them were febrile. 67 suffered from digestive disorders, 33 with diarrhoea. splenomegalia was noted in 16 cases and consciousness troubles in 13 cases. at the admission, 8 complications were observed. other infections were associated in 86 cases p ...19921494316
an outbreak of salmonellosis following consumption of monkey meat.an outbreak of salmonellosis due to consumption of monkey meat is reported among nine patients of whom one died. s. enteritidis phage type 8 was cultured from the stools of four patients. the spread of salmonellosis due to the consumption of monkey meat has not been reported before.19921495128
multifocal salmonella splenic abscess in a hiv-infected patient.a case of spleen abscess complicating salmonella bacteremia in a hiv-infected patient is reported for the first time. chronic pancreatitis and the infection of a pre-existing pseudocyst of the pancreas tail might have been the predisposing factor. infection developed before other aids criteria were evident in the patient. splenectomy plus antibiotic therapy was required to eradicate the process. salmonella enteritidis was cultured from two suppurated lesions of the excised organ.19921496727
nontyphi salmonella sepsis in an eight-year-old boy.nontyphi bacteremia is a rare event in older children, especially in those without predisposing conditions. we report a case occurring in a normal 8-year-old boy from south louisiana whose prolonged illness may, in part, have been iatrogenic. antibiotic treatment is also discussed.19921506762
the use of an antimicrobial and competitive exclusion combination in salmonella-infected pullet flocks.replacement pullets which had been found infected with salmonella were treated with antibiotics for 12 days, moved to a clean house by the 11th day and given 2 treatments with a competitive exclusion (ce) preparation on the 13th and 15th day. it was found necessary to supply a small amount of feed to generate a thirst in the birds and ensure efficient and rapid consumption of the ce preparation. salmonella could not be grown from the intestines or other organs of birds after this procedure had b ...19921419535
diagnostic application of monoclonal antibodies to outer membrane protein for rapid detection of salmonella.monoclonal antibodies produced to salmonella enteritidis outer membrane proteins were screened against 57 salmonella serovars and several related enterobacteria. those detecting all salmonella serovars and none of the related enterobacteria were used in a microtitre plate antigen capture elisa to screen clinical samples. sixty-one of 2100 samples yielded salmonellas after incubation for 24 h in selective media by conventional culture. of these 58 were detected by the elisa. sixty-five false posi ...19921517171

prevention of colonization by salmonella enteritidis pt4 in broiler chickens.field experiments in the netherlands and in scandinavian countries have shown that an undefined microflora originating from spf adult poultry will reduce considerably the colonization of young chicks by salmonella. a commercial product from this so-called nurmi concept, broilact, was studied for its effectiveness in preventing infection of broilers with salmonella enteritidis pt4 (s.e.). two trials were carried out, in which the birds were exposed to s.e. via 'seeder' birds placed among them. th ...19921419537
effect of faecal extract on the growth of salmonella enteritidis in artificially contaminated hens' eggs.1. salmonella enteritidis pt 4 grew in eggs stored at 25 degrees c, but not at 10 degrees c. 2. the incidence of generalised infection of the egg contents (greater than 10(6) salmonellas/ml) was greater in eggs inoculated with cells suspended in faecal extract compared to those with cells in ringer's solution. 3. the removal of most of the iron did not decrease the growth-promoting effect of the faecal extract.19921393670
techniques for the isolation of salmonellas from eggs.1. when the contents of 4 or more naturally-contaminated intact eggs were combined, the isolation rate of salmonella enteritidis was improved by extending incubation at 37 degrees c from 24 to 48 h before sub-culture. 2. the isolation rate of salmonellas from raw homogenised whole egg was significantly increased by the inclusion of novobiocin and cefsulodin in the primary culture media. 3. rappaport vassiliadis broth was found to be superior to selenite as a selective enrichment medium.19921393671
the influence of temperature on the behaviour of mixed bacterial contamination of the shell membrane of the hen's egg.the inner membrane of the air cell of hens' eggs was inoculated with pseudomonas putida, staphylococcus xylosus, enterococcus faecalis, escherichia coli and salmonella enteritidis. the first mentioned eventually dominated the contamination of the albumen of eggs stored at 4, 15, and 20 degrees c. the last mentioned did so in eggs stored at 37 degrees c. the interval between inoculation of the membrane and gross contamination of the albumen was markedly influenced by site of contamination relativ ...19921547832
use of competitive exclusion to protect newly-hatched chicks against intestinal colonisation and invasion by salmonella enteritidis pt4.1. the recommended dose of a commercial competitive exclusion (ce) product (broilact) was given orally to newly-hatched broiler chicks to protect them against oral challenge by salmonella enteritidis pt4. 2. in 5 replicate trials, half of the birds thus treated and half from untreated control groups were examined for salmonellas at 5 d and the other half at 12 d after challenge. 3. caecal contents were examined quantitatively while heart, liver and spleen samples were examined qualitatively by e ...19921393673
endotoxin tolerance is associated with altered gtp-binding protein function.previous studies have suggested that guanine nucleotide regulatory (g) proteins modulate endotoxin-stimulated peritoneal macrophage arachidonic acid (aa) metabolism. endotoxin-stimulated metabolism of aa by peritoneal macrophages is decreased in endotoxin tolerance (rogers et al. prostaglandins 31: 639-650, 1986). these observations led to a study of g protein function and aa metabolism by peritoneal macrophages in endotoxin tolerance. endotoxin tolerance was induced by the administration of sub ...19921400011
comparison of four different enzyme-linked immunosorbent assays for serological diagnosis of salmonella enteritidis infections in experimentally infected chickens.the program for the eradication of salmonella enteritidis from chickens in the netherlands is based on bacteriological examination of breeding flocks. there is a great need for a specific and sensitive serological screening test. for that purpose, we developed four different enzyme-linked immunosorbent assays (elisas), i.e., an indirect elisa with s. enteritidis flagellin, an indirect elisa with s. enteritidis lipopolysaccharide, a double-antibody sandwich blocking elisa that uses monoclonal ant ...19921400954
platelet-derived growth factor reduces the inhibitory effects of lipopolysaccharide on gingival fibroblast proliferation.lipopolysaccharide from a variety of bacterial sources is known to inhibit gingival fibroblast proliferation and synthetic activity and has been implicated in the pathogenesis of periodontal inflammation. however, it may be involved not only in pathogenesis but also be responsible for delayed wound healing following periodontal therapy. the aim of this investigation was to determine whether the inhibitory effect of lps on gingival fibroblast proliferation could be reversed by growth factors. hum ...19921403578
microbiological and histopathological effects of an induced-molt fasting procedure on a salmonella enteritidis infection in chickens.a study was undertaken to determine if a 2-week feed-removal protocol, as is used by industry to induce a molt in aging hens, would affect the course of a salmonella enteritidis infection. white leghorn hens aged 69-84 weeks were deprived of feed to induce a molt, and on day 4 of the fast, the birds were orally infected with 5 x 10(6) s. enteritidis. s. enteritidis organisms were enumerated in the spleen on day 6 and from the alimentary tract on days 7, 14, 21, 28, and 35. little difference was ...19921417591
the role of mice in the epizootiology of salmonella enteritidis infection on chicken layer farms.a microbiological survey of 10 mice-infested poultry farms was conducted to determine the role of mice in the epizootiology of s. enteritidis infection. five of the farms were rated as clean of s. enteritidis and five as contaminated based on culture results of environmental samples for s. enteritidis. of 2103 environmental samples and 715 mice and rats tested, 5.1% and 16.2%, respectively, were culture-positive for s. enteritidis. on contaminated farms, s. enteritidis was isolated from 24.0% of ...19921417592
an outbreak of gastro-intestinal illness caused by eggs containing salmonella enteritidis phage type 4.seven of nine people developed gastro-intestinal symptoms between 18 and 27 h after eating a trifle with a topping containing raw eggs. salmonella enteritidis phage type (pt) 4 was isolated both from the faeces of affected persons and from eggs remaining in the same box as those used to prepare the topping. the findings show that eggs being produced and sold in the u.k. still contain s. enteritidis pt4 and that this is continuing to cause human infection.19921569311
[chicken feed contaminated with salmonella enteritidis in a small egg-producing farm as source of a chain of infection in man--problems in tracing the mode of transmission].after having eaten rissoles containing eggs from a small laying flock two men fell ill with severe gastroenteritis by phage type 4 of s. enteritidis, one of them additionally with pancreatitis. in a sample of chicken feed and litter from the suspected hen-house we found the same phage type of s. enteritidis with the same virulence plasmid as in the faeces of the two patients. because of the dramatic increase of human salmonellosis and the growing numbers of cases with serious symptoms, resulting ...19921571623
occurrence of salmonella enteritidis in the u.s. commercial egg industry: report on a national spent hen survey.in order to estimate the prevalence and distribution of salmonella enteritidis in u.s. commercial egg-production flocks, a survey of spent laying hens was conducted over a 3-month period. seven of the 10 largest spent-hen processing plants in the united states participated. ceca were sampled twice weekly from birds presented for slaughter at these plants. samples were cultured for salmonella and s. enteritidis, and s. enteritidis isolates were phage-typed. overall, 23,431 pooled cecal samples we ...19921417594
comparison of plasmid profiles, phage types, and antimicrobial resistance patterns of salmonella enteritidis isolates in the united states.to evaluate the laboratory techniques for subtyping isolates of salmonella enteritidis, we compared the plasmid profiles (pp), phage types (pt), and antimicrobial susceptibility patterns (as) of two nationally representative samples of sporadic human s. enteritidis isolates from 1979 (n = 28) and 1984 (n = 37), 43 isolates from 20 outbreaks of s. enteritidis infections between 1983 and 1987, and 46 animal isolates selected from the u.s. department of agriculture veterinary services laboratory in ...19921572970
existing and emerging foodborne diseases.foodborne diseases, i.e. illnesses due to contaminated food, are one of the most widespread problems of the contemporary world. they are toxic or infectious by nature and are caused by agents which enter the body through the ingestion of contaminated food or water. these agents can be chemical like pesticide residues and toxic metals or biological like pathogenic microorganisms. foods contaminated by biological agents are, however, the major cause of foodborne disease. data recorded in different ...19921419523
[laboratory and clinical evaluation of meropenem in pediatric field].we performed laboratory and clinical evaluation of meropenem (sm-7338, mepm), a new carbapenem antibiotics, in pediatric field. pharmacokinetics of mepm was examined with 5 patients, at a dose of 10 mg/kg via 30 minutes drip infusion. mean plasma concentrations at 30 minutes, 1, 1.5, 2.5, 3.5 and 5.5 hours after dose were 18.8, 6.97, 3.62, 1.14, 0.43 and 0.12 micrograms/ml, respectively, with a half life of 0.96 hour. the urine recovery rate in 6 hours was 70.4%. clinical efficacy of mepm was ev ...19921479689
association of high fever and short bacterial excretion after salmonellosis.one hundred and two children with salmonella gastroenteritis were studied for factors affecting the length of convalescent bacterial excretion. there was a significant correlation between degree of fever and duration of excretion: a fever of greater than or equal to 40 degrees c had the shortest and no fever the longest duration of excretion. fever therefore appears to have a favourable prognostic influence on the length of salmonella excretion.19921580689
the role of 36 megadalton plasmid of salmonella enteritidis for the pathogenesis in mice.the pathogenesis associated with the 36 megadalton (md) plasmid of salmonella choleraesuis subsp. choleraesuis serovar enteritidis (s. enteritidis) was assessed by using the plasmid-containing strain al1190, plasmid-cured strain al1192, and plasmid-reintroduced strain al1193. after oral inoculation of strain al1190 or al1192 to c57bl/6 mice, mesenteric lymph nodes, spleens, and livers were examined for the numbers of viable bacteria and for the histopathological changes. the numbers of bacteria ...19921420563
therapy of experimental meningitis due to salmonella enteritidis.in many areas of the developing world, salmonella spp. account for greater than 50% of the gram-negative enteric organisms isolated from cerebrospinal fluid (csf). the response of salmonella meningitis to conventional therapy (chloramphenicol and/or ampicillin) is slow, complications arise frequently, and mortality rates of 60 to 80% are common. two newer agents, ceftriaxone and imipenem, were compared with ampicillin, chloramphenicol, and trimethoprim-sulfamethoxazole (tmp-smx) in the therapy o ...19921510418
