| Abstract : Salmonella Heidelberg has increasingly been reported as cause of human salmonellosis worldwide. In Brazil, S. Heidelberg has been reported in poultry but it is infrequently isolated from pigs. Here, we describe the isolation of S. Heidelberg resistant to colistin from slaughter pigs. Five pigs and their carcasses belonging to a same slaughter batch in ten consecutive days were sampled for fragment of intestine in the ileocecal region and sponges rubbed on the carcass surface (400 cm2 ) before chilling. Salmonella detection was performed according to the ISO 6579:2002. Intestinal content was also subjected to Salmonella enumeration by a miniaturized Most Probable Number (MPN) protocol. Salmonella isolates were characterized by antimicrobial... |

| ABSTRACT: Background: Despite a strong association between Salmonella isolation and slaughter hygiene, as measured by the Enterobacteriaceae levels on pre-chill carcass surfaces, a high variation in this association was observed between sampling days within the same slaughterhouse. It was hypothesised that in a scenario of high exposure on the farm, batches with a high prevalence of carrier pigs shedding a high number of Salmonella may enhance the risk of contamination on some slaughter days. Thus, the aim of this study was to assess the profile of Salmonella carried in the intestinal contents of slaughter pigs. Materials, Methods & Results: Ten pig batches slaughtered in a slaughterhouse were investigated for the presence of Salmonella. From each pig,... |

| Abstract: Antimicrobials have been widely used in veterinary medicine for disease treatment, disease prevention, and growth promotion. Although, the mechanisms about in-feed additives use are still not completely understood, it is accepted that its use improves feed efficiency by reducing the microbial load in the intestinal tract, thereby reducing the pressure on the immune system and increasing energy availability for the animal. However, disruption to commensal bacterial communities by antibiotics in some cases can increase the gut colonization by pathogenic bacteria. In this sense, the aim of this study was to evaluate the Escherichia coli antibiotic resistance and the gut microbiota profile from pigs raised in Brazilian farms with different in-feed... |

| Sulfato de colistina (Polimixina E) é um antimicrobiano peptídeo catiônico com atividade bactericida que atua contra bactérias Gram-negativas. É amplamente utilizada na suinocultura para a prevenção e tratamento de infecções causadas por enterobactérias. Além disso, em alguns países tem o seu uso permitido como aditivo zootécnico (10). Entretanto, a Organização Mundial da Saúde (OMS) considera esta droga como uma das substâncias antimicrobianas criticamente importantes para a saúde humana, sendo considerado o antimicrobiano de última eleição para determinadas enfermidades decorrentes de bactérias multirresistentes (13). Em novembro de 2015, foi publicado o primeiro caso de resistência antimicrobiana à colistina mediada pelo gene mcr-1 presente em plasmídeo... |

| Abstract In Brazil, since 2011 clinical cases of salmonellosis has been increasing substantially. Nevertheless, few information is available about the antimicrobial profile, distribution, serotypes and genetic relationship among the strains. The objectives of this study were: to identify the Salmonella serotypes, to characterize the in vitro antimicrobial resistance profiles and to determine the genetic relationship of clinical isolates in Brazil. During 2016, clinical isolates of Salmonella (111) from nine States were sent to Embrapa Swine and Poultry for complementary analysis. First, isolates were serotyped by Kauffmann White Scheme. In parallel, the strains were tested against fifteen antimicrobials by disk diffusion method and genotyping was performed... |
