Salmonella serovars isolated from humans in São Paulo State, Brazil, 1996-2003

Abstract

SUMMARYSalmonellosis remains an important cause of diarrheal illness in humans in São Paulo State, Brazil. In this study were identified 3554 Salmonella isolates from human infections, during the period 1996-2003. Among 68 different serovars determined, S. Enteritidis was the most frequent one in gastrointestinal and extra-intestinal infections accounting for 67.4% of all isolates. S. Typhimurium and S. enterica subsp. enterica (4,5,12:i:-) were most frequently isolated from children aged < 1-4 year-old, in contrast, people with S. Enteritidis infections were most likely to be 20-50 year-old. In our geographic area the continued laboratorial surveillance of salmonellosis, including serotyping, has showed the trends in Salmonella serovars causing infections in humans throughout the time.

Occurrence of Salmonella spp. in broiler chicken carcasses and their susceptibility to antimicrobial agents

“…in broiler chicken carcasses and to estimate the resistance profiles of the isolates. In Brazil, S. Enteritidis has been the most prevalent serovar detected in human infections (13), in broiler chicken carcasses (27), in broiler chicken parts (26), and in poultry flocks (18).…”

Severe sepsis from a Ciprofloxacin resistant salmonellosis in a kidney transplant recipient

“…Otherwise, in KTR it is rather common to find an extra-intestinal form of salmonellosis, such as meningitis, osteomyelitis, cholangitis and pneumonia (up to 35%), and bacteremia can be demonstrated in 60 to 70% of cases. [9][10][11] Bacteremia from Salmonella sp. is known to bear a high risk of mortality, as described in a series of cases from the Massachusetts General Hospital, in which an outbreak registered in 1990 caused the death of 18% of patients.…”

“…[6][7][8] In immunosuppressed patients, however, it can be more easily associated with bacteremia, and, consequently, to a much worse prognosis. [9][10][11] In this paper, we present a rare case of invasive diarrhea with severe sepsis caused by ciprofloxacin resistant Salmonella sp. in a KTR, and a brief literature review.…”

“…3 In the Southeast Brazil, the most common serotype is S. enteritidis (67.4%), followed by S. typhimurium. 4 Spontaneous Salmonella peritonitis can occur in cirrhotic patients with ascites. Other described sites of infection include the pericardium, thyroid, meninges, and bone marrow, mainly due to a deficiency in cellular immunity.…”
