Laboratory evaluation on pathogenic potentialities of Vibrio furnissii

Abstract

Sixteen strains of Vibrio furnissii recovered from 16 Brazilian patients with diarrhea were screened for virulence-associated factors. All strains were non-invasive, non-fimbriated, and did not produce either enterotoxins or cholera-like toxin. In contrast, most were hemolytic on blood agar and their broth-culture supernatants damaged HeLa cell monolayers. These cytolysins, as accepted for other enteropathogenic members of the family Vibrionaceae, might be determinants of pathogenicity in V. furnissii-mediated enteritis.

Isolation and characterization of a virulent Vibrio sp. bacterium from clams (Meretrix meretrix) with mass mortality

“…The results that some bacteria were being detected invading and entering into the gill epithelia and the lesion observed in the mantle of infected clam indicated that MM5 could infect and induce pathologic changes in M. meretrix. Magalhaes et al (1993) indicated that the most striking pathogenic property displayed by many culture supernatant fluids of V. furnissii was their lethal effects on epithelial cells. The infection of MM5 to the epithelia of hepatopancreas ( Fig.…”

First isolation of Vibrio furnissii (emerging Vibrio) from mussels (Mediterranean mussel and bearded mussel) in Turkey

“…The reason for this, only shellfish were investigate in this work. V. furnissii may be isolated from human feces at a high rate (2,10,22). V. furnissii isolation from bivalve molluscs may also indicate fecal contamination in the sea.…”

Vibrio furnissii: an Unusual Cause of Bacteremia and Skin Lesions after Ingestion of Seafood

“…Although V. furnissii has been associated with outbreaks and isolated cases of gastroenteritis (1,2,5,8,9), the relative pathogenicity of V. furnissii in most of these instances was unclear, in that other pathogens may have contributed to the disease or that the individuals were asymptomatic at the time of stool collection. The pathology of V. furnissii in gastroenteritis is potentially related to cytolysin and hemolysin production (9 blood, 2 from a wound, and 5 from stool.…”
