a prospective randomized comparison of cefotaxime vs ampicillin and chloramphenicol for bacterial meningitis in children.fifty children with bacterial meningitis were prospectively randomized to receive cefotaxime (50 mg/kg/dose every 6 hours) or ampicillin and chloramphenicol in standard doses. twenty-three patients received cefotaxime and 27 received standard therapy. bacterial isolates included: haemophilus influenzae (29), streptococcus pneumoniae (eight), neisseria meningitidis (eight), group b streptococci (three), and salmonella enteritidis (two). ten (34%) of the h. influenzae isolates were resistant to am ...19853847486
amelioration of the adverse effect of a gastrointestinal challenge with salmonella enteritidis on weanling rats by a yogurt diet.the response of yogurt-fed rats and the corresponding unfermented milk-fed rats to an infectious gastrointestinal challenge has been compared. after 1 (2 trials), 7 (4 trials), 14 and 21 (1 trial each) days on freeze-dried milk or yogurt diets, the rats were inoculated intra-gastrically by intubation per os with 4.5 x 10(10) +/- 0.7 colony forming units (mean +/- sem) of salmonella enteritidis. challenged and control rats were monitored during the 3 weeks post-inoculation for viability, weight g ...19853881008
salmonella bacteremia in systemic lupus erythematosus. eight-year experience at a municipal hospital.non-endemic salmonella bacteremia tends to occur in patients with chronic disease. we reviewed all cases of salmonella infection documented in adults at bellevue hospital during the years 1975-1982. unexpectedly, the most frequent underlying disease found among bacteremic patients was systemic lupus erythematosus (sle). patients with sle accounted for 6 of 30 salmonella bacteremias as compared with 13 of 2,388 non-salmonella gram-negative bacteremias. salmonella was the single most frequent gram ...19853881103
in vivo effects of bacterial lipopolysaccharide on proliferation of macrophage colony-forming cells in bone marrow and peripheral lymphoid tissues.changes in the number of macrophage colony-forming cells in various tissues of mice injected with lipopolysaccharide (lps) from klebsiella pneumoniae, escherichia coli, or salmonella enteritidis were studied. the injection of lps increased macrophage colony-forming cells in peripheral lymphoid tissues such as the spleen, mesenteric lymph nodes, and regional lymph node, although the same treatment caused the decrease of such cells in the bone marrow. this phenomenon was consistently observed when ...19853881351
alpha-aminoisobutyric acid transport in rat soleus muscle during endotoxic shock.we studied alpha-aminoisobutyric acid (aib) transport by skeletal muscle and the effect of insulin and na+ on the transport process during endotoxic shock. rats (140-160 g) were injected with salmonella enteritidis endotoxin (20 mg/kg iv) or saline and killed 5 h later. at that time an elevation of blood lactate and hypoglycemia marked the onset of shock in rats given endotoxin. aib uptake was measured in isolated soleus muscles in vitro. total cellular aib uptake in the endotoxic muscles was 25 ...19853881997
passage of salmonella enteritidis and salmonella thompson through chick ileocecal mucosa.the passage of salmonella enteritidis and s. thompson across the cecal mucosa has been visualized in an electron microscope study with the freshly hatched chick as a model. the uptake of salmonellae by macrophages took place in the cecal lumen; the macrophages became abnormal and often ruptured to release organisms back into the lumen. the entry of bacteria into the epithelial cells was associated with a series of pathological changes, beginning with the appearance of active golgi apparatus and ...19853882568
determination of the presence of root-bound endotoxin using the local shwartzman phenomenon (lsp).the purpose of these studies was to determine, by attempting to elicit the local shwartzman phenomenon (lsp), if the material extracted from periodontally involved root surfaces is actually endotoxin or only an endotoxin-like substance. a total of 719 periodontally involved teeth and 201 unerupted third molars yielded pooled samples of root surface grindings which were treated with the endotoxin extraction technique nonpyrogenic saline or pyrogen-free water. in the first study each of the recons ...19853882934

salmonella infections in patients with acquired immunodeficiency syndrome.salmonella infections occurred in six patients with acquired immunodeficiency syndrome (aids) and one patient with probable aids. the immune system defects increase the susceptibility of patients with aids to salmonella infections. recognition of salmonellosis in patients with aids is important because of a high propensity of this organism to invade the bloodstreams of these patients, and because, unlike other infections in patients with aids, this infection can be easily treated.19853885890
an outbreak of antibiotic-resistant salmonella enteritidis in liberia, west africa.between october 1980 and august 1982, 100 patients in the pediatric population at curran lutheran hospital, zorzor, liberia were identified as having multiple drug-resistant salmonella enteritidis serotype enteritidis. the illness usually presented as an enteric fever but also as meningitis, gastroenteritis, empyema, subcutaneous abscesses, chronic otitis media, or a combination of these conditions. predisposing factors were young age and debilitation from malnutrition or measles. the mortality ...19853886805
a rare presentation of systemic salmonellosis.we are reporting an unusual case of disseminated salmonella enteritidis d, phage group e2 infection in an 18-year-old male, which was resistant to massive antibiotic treatment. rare complications such as pylephlebitis, mediastinal adenopathy, osteomyelitis with pathological clavicular fracture, osteitis and spondylitis were observed. we found an immunological defect that no doubt contributed to this severe illness.19853888847
salmonella enteritidis bacteremia in childhood.we have reviewed the clinical course of 32 children with salmonella enteritidis bacteremia and compared them with 135 children with acute gastroenteritis caused by s. enteritidis at wyler children's hospital over 4.5 years. analysis of symptoms of infection, the initial laboratory evaluation, the initial impression of the severity of illness, the clinical course, and the eventual outcome showed no differences between children with bacteremia and those with acute gastroenteritis, nor did a compar ...19853891884
