Abstract

Alimentary toxiinfections produced by Salmonella from view point of frequency and hygienic-sanitary implications are on the first place in most of countries. At animals the infection is maintained by recycling the waste from slaughterhouses as food for animals, fecal-oral transmission, and fecal contaminations of eggs. They are widely distributed in nature, with humans and animals being their primary reservoirs. All salmonellae have been placed in two species, S. enterica and S. bongori with 2,500 or so serovars being divided into 5 species or groups, most of which are classified under S. enterica, the type species. The major groups correspond to the following subspecies: group II (S. enterica subsp. salamae), group III a (S. enterica subsp. arizonae), group III b (S. enterica subsp. diarizonae); group IV (S. enterica subsp. houtenae); and group VI (S. enterica subsp. indica). The former group V organisms have been elevated to species status as S. bongori. Objective: Study regarding antibiorezistance of Salmonella strains isolated from fish flour. Design. From fish flour were isolated 9 Salmonella strains. Procedures. It's used the methodology ISO 6579/1997 respecting the identifications germs of genus Salmonella. It's was used selective mediums to represented agar BS (agar with sulfit de bismut), HE (agar Hektoen enteric) and XLD (agar with xiloza-lizina-dezoxicolat). The conformed biochemical and serological was been realized. The system of identification biochemical was API 20 E. Results. From fish flour were isolated 9 Salmonella strains (63%) as follows: Saint Paul (6%), Montevideo (6%), Newport (7%), London (6%), Choleraesuis (8%), Meleagridis (8%), Derby (12%), Dublin (4%), Agona (6%). It was tested the resistance of 9 strains isolated from fish flour against: streptomycin (S. montevideo), nalidixic acid (S. agona), tetracycline (S. newport, S. meleagridis, S. derby), flumequil si gentamicine (S. london) to observe multiresistant strains.
