Quinolones resistance in Salmonella spp. isolated from broilers and chickens’ carcasses under federal inspection

et al. 2020

We analyzed 77 Salmonella spp. strains, from which 20 were isolated from broilers (cloacal swabs) and 57 from chickens from slaughterhouses under federal inspection. The following serotypes were identified: Salmonella Saint Paul (29), Salmonella Heidelberg (27), Salmonella Anatum (9), Salmonella Cerro (5), Salmonella Senftenberg (5), Salmonella enterica (O: 4,5) (1) and Salmonella enterica (O: 9.12) (1). Fifteen strains (19.5%) were resistant to enrofloxacin, six (7.8%) to ciprofloxacin, and 26 (33.8%) to nalidixic acid in the Disk Diffusion Test. The fifteen enrofloxacin resistant strains were selected for the PCR to detect the genes gyrA, gyrB, parC, and parE, and genetic sequencing to identify mutations in these genes. Five strains (33.3%) had point mutations in the gyrA gene, and one (6.7%) presented a point mutation in the parC gene. None of the 15 strains had mutations in the gyrB and parE genes, and none had more than one mutation in the gyrA gene or the other genes. The presence of point mutations in the strains studied corroborates with the phenotypic resistance observed to nalidixic acid. However, it did not explain the resistance to fluoroquinolones found in the 15 strains. Other mechanisms may be related to the fluoroquinolones resistance, highlighting the need for additional mutation screening.

“…Entretanto, variações de prevalência são descritas em diversos locais do Brasil. Cardoso et al (2015) e Yamatogi et al (2016), no estado de São Paulo, analisaram carcaças provenientes de matadouros com SIF e encontraram, respectivamente, 14,6% e 58% de carcaças positivas para Salmonella spp..

Prevalência e susceptibilidade antimicrobiana de sorotipos de Salmonella spp. isolados de frangos vivos e carcaças no estado do Rio de Janeiro

et al. 2018

RESUMO: A presença de Salmonella spp. em produtos de origem avícola e seus subprodutos se mostra um grande desafio para a produção comercial. Dados de prevalência, dos sorotipos circulantes e do perfil de susceptibilidade antimicrobiana de cepas de Salmonella spp. no Estado do Rio de Janeiro são escassos. Portanto, objetivou-se detectar a presença Salmonella spp. em frangos vivos e carcaças em matadouros do Estados do Rio de Janeiro, identificar os sorotipos e avaliar a susceptibilidade antimicrobiana dessas cepas para fluoroquinolonas e betalactâmicos. Foram coletadas 60 amostras cloacais de frangos vivos e 60 amostras de carcaça de seis matadouros sob Inspeção Estadual (SIE). Os isolados foram sorotipificados e testados frente a oito antimicrobianos: enrofloxacina, ciprofloxacina, norfloxacina, cefalotina, ceftiofur, cefotaxima, amoxicilina/ácido clavulânico e ampicilina pelo método de difusão em disco. Os resultados mostraram uma prevalência de Salmonella spp. de 1,66% (1/60) em amostras de suabe de cloaca e de 26,66% (16/60) em carcaças. Em amostras de suabe de cloaca, somente o sorotipo Senftenberg (1,66%) foi isolado. No total, foram isolados sete sorotipos diferentes nas carcaças: Senftenberg (15%) o mais frequente, seguido por Mbandaka (8,3%), Schwarzengrund (3,3%), Cerro (3,3%), Ohio (3,3%), Minnesota (1,66%) e Tennessee (1,66%). Em relação à susceptibilidade antimicrobiana, 29 (87,87%) isolados foram sensíveis a todos os antimicrobianos testados e 4 (12,12%) isolados foram resistentes a pelo menos três antimicrobianos betalactâmicos ou mais. Não foi observada resistência às fluoroquinolonas. Os resultados encontrados demonstram uma prevalência de Salmonella spp. acima da esperada em matadouros do Estado do Rio de Janeiro, além da presença de vários sorotipos de Salmonella spp. A resistência encontrada para betalactâmicos alerta para a disseminação dessas cepas pela cadeia alimentar.

The present study aimed at isolating and characterizing Salmonella spp. from chicken cuts marketed in Francisco Beltrão, PR, and verify the resistance profile of the isolates against antimicrobials used in human therapy. Samples of chicken cuts (n=40) were purchased from supermarkets and submitted to microbiological analysis for the detection of Salmonella spp. The suspected colonies underwent biochemical testing for the identification of enterobacteria. Four colonies were selected from each sample positive for Salmonella spp., totaling 28 isolates that were tested for antimicrobial sensitivity. Colonies that showed resistance to ceftriaxone were subjected to extended-spectrum beta-lactamases (ESBL). Among the analyzed chicken samples, seven (17.5%) showed biochemical behavior characteristic of Salmonella spp. Among the 28 isolates, seventeen different resistance profiles were found, of which 46.42% (n=13) had a multi-resistance profile, and 21.4% (n=6) of the isolates had a phenotype for ESBL production. The strains of Salmonella spp. isolated from chicken cuts found in this study showed a high level of resistance to antimicrobials of different classes and of last generations, these data serve as a warning, as they put the human treatment of salmonellosis at risk.
