antimicrobial susceptibility of salmonella isolates from the broiler chicken industry in ontario.antibacterial drug resistance among 219 salmonella isolates recovered during 1974 from poultry and poultry environments at the various production stages of broiler chickens in three integrated ontario companies are recorded. all isolates were susceptible to ampicillin, trimethroprim-sulfamethoxazole complex, furazolidone, cephaloridine and amoxicillin. a relative increase in resistance to tetracycline and streptomycin with an accompanying decrease in resistance to triple sulfa compound was recor ...1977318909
[transferral of salmonella from mother to newborn infant (author's transl)].two newborn infants were infected with salmonella originating from their mothers. after infection of a newborn infant with salmonella typhi from a mother, known for a long time to be a chronic carrier, no pathological findings were observed but the child continued to secrete typhoid bacilli for three years. the infection of the second child with s. panama, from a mother recognized as a carrier post-partum, caused a fulminating diarrhoea accompanied by septicaemia which had a fetal outcome.1977318985
[the isolation of enteritis causing salmonellae from the sputum].in the light of the author's diagnostic experience, attention is drawn to the fact that enteritis salmonellae appear to be more frequently present in sputum than in generally supposed. the diagnostic and epidemiologic implications of this observation are discussed.1977319522
treatment of chronic salmonella carriers. study with 40 cases of s. typhi, 19 cases of s. paratyphi b and 28 cases of s. enteritidis strains.the present stage of our studies suggests that, provided a highly effective combined therapy is, and can be, carried out correctly, all excreters can be cured of their chronic carrier state by chemotherapy within 8-12 weeks. although we cannot recommend a universal therapeutic regimen for all patients, a highly effective 'basic therapy' (rmp+tsp) is available for the majority of the cases, needing occasional modification, depending on the specific requirements of the individual patient as shown ...1977319963
comparison of endotoxin and leukocytic pyrogen pyrogenicity in newborn guinea pigs.guinea pigs under 8 days of age generally are unable to develop fever (viz., deltatre greater than 0.5 degrees c) in response to a standardized dose of endotoxin (2 mug/kg iv of salmonella enteritidis [se]). this study was undertaken to determine whether this lack of responsiveness might be due to an incapacity of leukocytes from young neonates to produce sufficient leukocytic pyrogen (lp). three series of experiments were performed at ta = 27 degrees c: guinea pigs aged 0-2, 4, and 8 days were ...1977320171

prevention of endotoxin-induced abortion by treatment of mice with antisera.small amounts of bacterial lipopolysaccharides (lps), usually extracted from smooth organisms, have previously been shown to interrupt pregnancy in mice. the findings reported here demonstrate that lps obtained from rough bacterial strains were also abortifacient. moreover, lipid a, which represents a common toxic structure of lps in many species of gram-negative enterobacteriaceae, had the same activity, whereas the nontoxic polysaccharide moiety did not affect pregnancy. our data also showed t ...1978342637
dexamethasone antagonism of glucose dyshomeostasis in endotoxin shock.dexamethasone acetate (100 microgram ip) protected male holtzman rats (300-330 gm) against endotoxin shock due to salmonella enteritidis lipopoly-saccharide b iv. endotoxin (5.0 mg/rat) produced hypoglycemia within 180 minutes, ie, plasma glucose fell from 87 to 24 mg/dl; dexamethasone prevented the hypoglycemia, ie, plasma glucose levels were 129 mg/dl at 180 minutes after endotoxin. dexamethasone antagonized both endotoxin-induced depression of hepatic gluconeogenesis and enhanced glucose oxid ...1978280423
combined activitiy of clavulanic acid and ticarcillin against ticarcillin-resistant, gram-negative bacilli.fifty-one clinical isolates of ticarcillin-resistant, gram-negative bacilli were tested for susceptibility to combinations of ticarcillin and clavulanic acid (brl 14151), a potent beta-lactamase inhibitor. minimal inhibitory concentrations (mics) were measured by a microdilution method, and minimal bactericidal concentrations for selected strains were measured by the broth dilution method. ticarcillin mics were >/=128 mug/ml for all and >/=512 mug/ml for 38 (75%) of the strains. thirty-nine stra ...1978308792
effect of salmonella enteritidis 11rx infection on two-stage skin carcinogenesis in mice.s. enteritidis 11rx infection inhibits the growth of a number of transplantable tumours in mice. in addition, oral infection of mice with s. enteritidis 11rx inhibits colon carcinogenesis by 1,2 dimethylhydrazine. this study has examined the effect of s. enteritidis 11rx infection on two-stage skin carcinogenesis in mice using 7,12 dimethylbenz(a)anthracene (dmba) as initiator and croton oil as promoter. no protection was observed in either laca or (balb/c x c57bl/6j)f1 mice when live 11rx was r ...1978110298
antibacterial functions of macrophages in experimental protein-calorie malnutrition. ii. cellular and humoral factors for chemotaxis, phagocytosis, and intracellular bactericidal activity.cellular and humoral aspects of the antibacterial activity of macrophages during experimental protein-calorie malnutrition were studied. there were no defects in chemotaxis or bactericidal activity of cells from protein-deficient animals, although phagocytosis-associated oxygen consumption and hexose monophosphate shunt activity were depressed. however, marked impairment of humoral chemotactic factors generated in the peritoneal cavity by glycogen injection and of heatlabile serum opsonins for s ...197898599
strain-dependent cytotoxic effects of endotoxin for mouse peritoneal macrophages.the cytotoxic effects of bacterial lipopolysaccharides (lps) on mouse leukocytes have been examined in vivo and in vitro. intraperitoneal injection of lps into c57bl/6 mice greatly reduced the recovery of mononuclear cells; lps was cytotoxic for macrophages, but had a mitogenic effect on lymphocytes. similar effects of lps on peritoneal leukocytes were observed in vitro. when monolayers of adherent peritoneal cells were studied in vitro, cytotoxicity was also observed, suggesting that the effect ...1978101460

ribonucleic acid in the immune response.in the studies of experimental salmonellosis, immunization of mice with a live vaccine ser of s. enteritidis was found to be effective against further infection with virulent s. enteritidis 116--54. macrophages obtained from the peritoneal cavity, subcutaneous tissue or liver of immunized mice inhibited intracellular growth of bacteria and resisted cell degeneration caused by engulfment of virulent 116--54 bacteria. this immunity was called cellular immunity. we discovered by chance in 1961 a tr ...197881465
genetic properties of the salmonella enteritidis r404 plasmid aggregate. ii. separation of plasmids by transformation.transformational separation of plasmids from r404 plasmid aggregate found in salmonella enteritidis strain was performed. three classes of transformants differing in their resistance patterns were isolated. genetic properties of the transformants suggest that their resistance is determined by single plasmids. plasmid pck3 (tra-apcbcrsusm) and pck4 (tra-apcbcrcm) are nonconjugative while plasmid pcg1 (traapcbcrsusmtckmnm) is conjugative. separation of all plasmids of r404 plasmid aggregate allowe ...197881594
genetic properties of the salmonella enteritidis r404 plasmid aggregate. iii. entry exclusion features of its separative forms.the genetic relationship of four plasmids separated from r404 plasmid aggregate has been characterized by investigating entry exclusion and intracellular incompatibility. it has been found that the four plasmids exist in an autonomous state in cells carrying the aggregate. they are compatible and the two conjugative plasmids possess different tras genes.197886280
genetic properties of the salmonella enteritidis r404 plasmid aggregate. iv. reconstruction in r404 plasmid aggregate and separation of twelve genetically distinct derivative forms.r404 plasmid aggregate is composed of two conjugative and two nonconjugative plasmids. plasmid aggregate reconstructed from separated plasmids had the same genetic properties as the original r404 plasmid aggregate. it was found that plasmids of r404 factor could be transferred in conjugation in twelve different sets. these twelve genetically distinct classes of transconjugants formed only six groups differing in phenotypic characters.197987112
plaque-forming cell response in balb/c mice to two preparations of lps extracted from salmonella enteritidis.the pattern of development of antibody-forming cells in balb/c mice after immunization with pw-lps or tca-lps was shown to be different. on days 10 and 20, the primary response to pw-lps was characterized by a low level of igm synthesis. the plaque-forming cell (pfc) response to tca-lps, however, increased from day 10 to day 20. initially, igm was the only detectable antibody synthesized but by day 20 a significant number of igg-producing spleen cells had developed. after a secondary immunizatio ...197987428
endotoxins of anaerobic gram-negative rods.endotoxic lipopolysaccharides (lps) isolated from fusobacterium are similar to those of salmonella with respect to chemical composition, o-antigenic specificity and endotoxic activity. bacteroides lps are highly atypical with respect to the chemical composition, and their endotoxic activity is low. o-antigenic specificity is present. b. fragilis lps is chemotactic for polymorphonuclear leukocytes in vitro and in vivo. the chemotactic activity is brought about by activation of the alternative com ...197988759
