However, inan increase in the number of cases was observed. Fecal markers of inflammation are not reliable indicators of specific enteric pathogens since they are associated with pathologic process rather than a specific infection.

Aeromonas species bacteremia in nonimmunocompromised hosts. Bacteremia, with or without the existence of enteritis outbreaks, is caused by Salmonella typhimurium, Salmonella paratyphi A and B and by Salmonella choleraesuis. The initial symptoms are nonspecific fever, weakness, and myalgia among others.

F., M. L. Cohen. The aim of this review is to provide a comprehensive update on the current classification and identification of Haemophilus and Aggregatibacter species with exclusive or predominant host specificity for humans.

Haemophilus influenzae and some of the other Haemophilus species are commonly encountered in the clinical microbiology laboratory and demonstrate a wide range of pathogenicity.

Salmonella species are Gram-negative, flagellated facultatively anaerobic bacilli characterized by O, H, and Vi antigens. There are over known serovars which current classification considers to be separate species. Figures 2 and 3 summarize the pathogenesis of Salmonella enterocolitis and.

Table Infectious Causes of Acute and Persistent Diarrhea, Known Pathogenicity and Detection in the Routine Diagnostic Laboratory or the Research Laboratory. Salmonella is a genus of rod-shaped (bacillus) Gram-negative bacteria of the family two species of Salmonella are Salmonella enterica and Salmonella bongori.

S. enterica is the type species and is further divided into six subspecies that include over 2, serotypes. Salmonella species are non-spore-forming, predominantly motile enterobacteria with cell diameters.
