We retrospectively analyzed clinical and epidemiological data on and laboratory characteristics of 53 cases of aeromonas septicemia. Only four Aeromonas genomospecies (species defined by DNA relatedness) were associated with the 53 cases, with Aeromonas hydrophila (sensu stricto) predominating (47%). Nearly 60% of all Aeromonas isolates from blood fell into one of four somatic groups: serogroups O:11, O:16, O:18, and O:34. Unlike Aeromonas-associated gastroenteritis, septicemia did not peak in frequency during the warmer months but rather was most common in January through March, when approximately 40% of cases occurred. In vitro tests of the pathogenicity of 20 selected blood isolates of Aeromonas indicated that resistance to complement-mediated lysis, elevated levels of protease and hemolysin activity, and the ability to elaborate siderophores correlated with higher virulence. Species and serogroup designations also correlated with the degree of virulence. Susceptibility studies of 50 strains indicated that A. hydrophila was the most drug-resistant species and that Aeromonas veronii was the most susceptible. Susceptibility to first- and second-generation cephalosporins and carbenicillin was species-associated.

Two sisters, 2 and 5 years of age, suffered from acute haemolytic anaemia occurring after gastroenteritis with Escherichia coli O157. One patient developed clinical signs of severe and acute intravascular haemolysis and sepsis. She received transfusion and antibiotic therapy. The second patient presented with mild to moderate haemolytic symptoms only. None of them developed renal impairment. In serum of both children, elevated titres of short-lived agglutinins were demonstrated in the indirect haemagglutination assay consisting of sheep erythrocytes coated with lipopolysaccharide from E. coli O157. By immunoblot analysis IgM antibodies against the O157 lipopolysaccharide were demonstrated in the acute phase sera but not in follow up sera taken 2 months after disease. On erythrocyte membranes, adsorption of microbial antigens was detected by use of a pool-immunoglobulin fluorescence test. The immunological status of both patients was normal. Complete recovery from haemolytic disease was observed without further therapy. Microbial antigens attached to the cell surface were assumed to be the pathophysiological cause of E. coli O157 associated haemolytic anaemia in two siblings.

Among 20- to 59-year-old residents of New York City who have septicemia, gastroenteritis, urinary tract infection, and multiple site infections due to Salmonella, those listed in the New York City AIDS Registry were highly overrepresented. Among the patients listed in the registry, males outnumbered females by 4:1 (septicemia), 9:1 (multiple site infections), 5.6:1 (gastroenteritis), and 2.5:1 (urinary tract infection); among patients not listed, males outnumbered females by 2.7:1 (septicemia), 3:1 (multiple site infections), 1.2:1 (gastroenteritis), and 1.6:1 (urinary tract infection). These results strongly suggest that most nonlisted males with septicemia and multiple site infections, and a minority with gastroenteritis and urinary tract infection, were human immunodeficiency virus (HIV)-positive. Among individuals who were HIV-positive, or likely to be so, Salmonella enteritidis was more competent in causing septicemia and less competent in causing gastroenteritis than was Salmonella typhimurium; among HIV-negative individuals, the reverse was true. The different capacities for infection with and invasiveness of S. enteritidis, S. typhimurium, and other Salmonella serotypes in HIV-positive and HIV-negative individuals and the use of HIV testing for Salmonella-infected individuals are discussed.

A prospective study of 90 children admitted to Ethio-Swedish Children's Hospital in Addis Ababa, Ethiopia, in 1992 with severe protein-energy malnutrition assessed the clinical profile and patterns of infection. The children, who ranged in age from 4 to 60 months, suffered from marasmus (49%), marasmic-kwashiorkor (42%), and kwashiorkor (19%). Septicemia, the most alarming complication of severe protein-energy malnutrition, was present in 32 children (36%); gram-negative enteric bacilli were the most common bacterial pathogen. 57 children (63%) had pneumonia and 23 (26%) had tuberculosis. Another 33 (37%) had a urinary tract infection. 17 children (19%) presented with diarrhea, 33 (37%) had clinical and radiologic evidence of rickets, and 15 (17%) had clinical evidence of vitamin A deficiency. There were 29 deaths in this series (from septicemia, gastroenteritis, pneumonia, and disseminated tuberculosis), for a case fatality rate of 32%. Mortality was significantly greater among children with a total serum protein of 5 gm% or less and those with systemic infection. This profile differs from those recorded in other developing countries, suggesting that severe protein-energy malnutrition has clinical and geographic heterogeneity.

There are many bacterial and viral pathogens that have been associated with enteric disease during the newborn period. These pathogens have widely different mechanisms of action on the intestinal epithelium and are associated with a spectrum of clinical findings. Infected infants can be asymptomatic, have gastroenteritis, or have a fulminant sepsis picture. To determine therapy and institute appropriate infection control measures requires the ability to recognize the clinical syndrome and correctly interpret laboratory results. All of these principles can be applied to the premature infant in the neonatal intensive care nursery as well as the full-term infant at home.

Over a 28-year period, 113 out of 2986 (3.8%) patients dialysed for acute renal failure at a referral center in North India were diagnosed to have acute renal cortical necrosis (ACN). Obstetric causes were responsible for ACN in 56.6% patients and nonobstetric causes in 43.4%. Within the obstetric group, ACN developed in association with complications of late pregnancy in 37.1% and following septic abortion in 19.5%. The various nonobstetric causes included viperine snake bite in 14.2%, hemolytic uremic syndrome in 11.5%, renal allograft rejection in 5.3%, acute gastroenteritis in 4.4%, acute pancreatitis in 3.5%, septicemia in 2.7%, and trauma and drug-induced IV hemolysis in 0.9% patients. Total anuria was the commonest presenting feature and was noted in 78.8% of patients. Renal histology showed diffuse cortical necrosis in 62.8% and patchy lesions in 37.2% patients. Computerized tomography (CT scan) of the kidneys revealed characteristic diagnostic findings in all the 5 patients in whom it was done. Dialytic support could be withdrawn as a result of improvement in renal function in 19 patients with patchy cortical necrosis. Dialysis-free survival of as long as 12 years has been recorded. The present study shows that, in contrast to the Western world, ACN continues to be a common cause of acute renal failure in developing countries. CT scan of the kidneys is helpful in establishing an early diagnosis.

The epidemiology of salmonellosis has undergone a change during the last 2 years. An increase in the number of cases of enteritis and sepsis caused by Salmonella enteritidis has been observed. We report on the case of a 65-year-old woman with mitral valve endocarditis due to Salmonella enteritidis. The infective endocarditis occurred without prior episodes of gastroenteritis. After having undergone prosthetic valve replacement and antibiotic therapy with ciprofloxacin, the patient recovered completely.

The role of the genus Edwardsiella in human illness is reviewed. Of the three recognized species, only Edwardsiella tarda has been demonstrated to be pathogenic for humans. Chief infections associated with this species include bacterial gastroenteritis, wound infections such as cellulitis or gas gangrene associated with trauma to mucosal surfaces, and systemic disease such as septicemia, meningitis, cholecystitis, and osteomyelitis. Risk factors that are associated with E. tarda infections include exposure to aquatic environments or exotic animals (e.g., reptiles or amphibia), preexisting liver disease, conditions leading to iron overload, and dietary habits (e.g., raw fish ingestion). Although studies indicate that this bacterium is susceptible to most commonly prescribed antibiotics, fatal gastrointestinal and extraintestinal infections have been described.

One hundred and twenty patients with a mean age of 38 years (range 12-85 years; M 91, F 37) were studied over a period of 5 years in a teaching hospital in Dhaka. Sixty-two patients presented with probable anuria with 1-4 days' duration, 63 patients presented with oliguria, and 3 were nonoliguric. The causes of acute renal failure were medical (94), surgical (22), obstetrical (13). Of the medical cases, the causes were gastroenteritis in 42 cases, gastroenteritis with CNS involvement in 11 cases, rapidly progressive glomerulonephritis in 10 cases, acute viral hepatitis in 8 cases, and septicemia in 8 cases. Of 22 surgical cases, postoperative acute renal failure was the cause in 9, road traffic accident in 6, and renal calculus disease in 7. There were 13 cases in the obstetrics group, of whom 9 were due to abortion, 2 were due to preeclampsia, and the other 2 were postoperative. The mean blood urea of all cases was 35 mmol/L and serum creatinine was 988 mumol/L. Dialysis was required in 105 cases; of these, 72 were medical cases, 21 were surgical cases, and 12 were obstetric cases. The overall survival rate was 75%. The improved survival is probably due to timely referral and prompt medical management.

Vibrio parahemolyticus is a halophilic marine vibrio commonly associated with outbreaks of acute gastroenteritis which also sometimes causes serious wound infection. It is an uncommon cause of septicemia. A few reports suggest that patients with chronic liver disease and leukemia are more susceptible. A case of liver cirrhosis with septicemia caused by this organism is discussed. The patient's condition rapidly deteriorated, and he died 12 hours after admission.
