The C. yacare placed in breeding conditions have a preserved genetic pool, which requires the enhancement of its zootechnical characteristics to solve some obstacles. Among them is the natural occurrence of Salmonella spp. in wild C. yacare. To address this problem, some breeders have adopted the use of probiotics to reduce Salmonella spp. in the digestive tube of crocodilians. The purpose of this study was to verify whether the addition of probiotics in animal feed reduces the isolation frequen...

AbstractBackground: Edwardsiella tarda infections are frequent causes of severe outbreaks in the fish farming industry besides representing possible zoonotic risks. However, naturally occurring outbreaks that affect various species besides fishes are seldom described.Aim: To report an outbreak of acute mortality caused by E. tarda affecting multiple species that inhabited a natural pond in the state of Sao Paulo, Brazil.Materials and methods: Three adult tilapias, three Mallard ducks and one Sno...

Psittacine birds have been identified as reservoirs of diarrheagenic Escherichia coli, a subset of pathogens associated with mortality of children in tropical countries. The role of other orders of birds as source of infection is unclear. The aim of this study was to perform the molecular diagnosis of infection with diarrheagenic E. coli in 10 different orders of captive wild birds in the state of Sao Paulo, Brazil. Fecal samples were analyzed from 516 birds belonging to 10 orders: Accipitriform...

ABSTRACT The fructan inulin-type oligosaccharides favor the multiplication of some bacterial genera in the intestine, promoting a prebiotic effect. This study evaluated the effect of inulin extracted from yacon roots (Smallanthus sonchifolius) on intestinal colonization of broilers experimentally infected with Salmonella Enteritidis. Sixty-one day old chicks were grouped into three treatments, with two replicates, and reared until 21 days. Birds in the yacon group received 100mg of inulin/day or...

The aim of this study was to perform the identification and molecular characterization of Arcobacter cryaerophilus and Arcobacter butzleri isolated from caiman (Caiman yacare), kept at a production farm, in Brazil. Forty fecal samples were analyzed. After isolation and identification, 21/40 strains of A. butzleri and 19/40 strains of A. cryaerophilus were subjected to PCR for potential virulence gene detection. The results of the PCR showed 38/40 strains positive for the cadF, cj1349, ciaB, and ...
