Serovars of Salmonella spp isolated from broiler chickens and commercial breeders in diverse regions in Brazil from July 1997 to December 2004

Abstract

Avian salmonellosis is a worldwide problem to the poultry industry, from the point of view of animal health and public health as well. The aim of the present study was to survey the most common Salmonella serovars in commercial breeders or broiler flocks from several regions in Brazil. The results of the present study indicated a high incidence of S enterica subspecies enterica serovar Enteritidis in breeders (57.5%) and broilers flocks (84.0%). The importance of these findings lies in the fact that S. Enteritidis has become the most frequent serovar responsible for foodborne outbreaks and sporadic cases of salmonellosis in humans

Occurrence and antimicrobial resistance of Salmonella serotypes isolates recovered from poultry of Western Paran, Brazil

“…The presence of the main serotype, S. enteritidis in poultry was also confirmed by other researchers in various regions of Brazil, such as Paraná (Souza et al, 2011), São Paulo (Hofer et al, 1998;Lima et al, 2009), Bahia, Ceará, Goiás, Paraná, Mato Grosso, Mato Grosso do Sul e Santa Catarina (Kanashiro et al, 2005), Rio Grande do Sul (Ribeiro et al, 2007) and the other states in the Northeast (Duarte et al, 2009). Similarly, in other countries, the occurrence of S. enteritidis isolated from broilers in Portugal (Antunes et al, 2003), Spain (Fernandez -Rubio et al, 2009) Lithuania (Ruzauskas et al, 2005) and United States (Burkholder et al, 2008) was observed.…”

Occurrence of Salmonella spp. in broiler chicken carcasses and their susceptibility to antimicrobial agents

“…in broiler chicken carcasses and to estimate the resistance profiles of the isolates. In Brazil, S. Enteritidis has been the most prevalent serovar detected in human infections (13), in broiler chicken carcasses (27), in broiler chicken parts (26), and in poultry flocks (18).…”

Assessment of Salmonella spp. presence among broilers of naked neck Label Rouge lineage in Northwest region of Paran State, Brazil

“…in broilers reared under confined and intensive system both in Brazil (Kanashiro et al, 2005;Ribeiro et al, 2007) and other countries (Limawongpranee et al, 1999;Siemon et al, 2007;Alali et al, 2010). Kanashiro et al (2005) found prevalence of 84% in broiler flocks and 57.5% in commercial breeders in the following Brazilian States: Bahia, Ceará, Goiás, Paraná, Mato Grosso, Mato Grosso do Sul, Santa Catarina and São Paulo. Alali et al (2010) compared the prevalence of Salmonella in organic and conventional broiler poultry farms in the same company in North Carolina and verified that the Salmonella prevalence in fecal samples were 5.6 and 38.8% in the organic and conventional farms, respectively.…”
