Resumo: Thermophilic species of Campylobacter spp. are often cited as the most common etiologic agent in cases of foodborne illnesses in several countries. When ingested even in small quantities (400 to 500 cells) this organism, through the mechanisms of pathogenicity, the host develops infectious gastroenteritis known as campylobacteriosis. This disease is closely related to the intake and improper handling of contaminated food, especially poultry, and birds the main reservoir of the microorganism. Poor knowledge climbs the role of eggs in the transmission of campylobacteriosis, based on the annual consumption of the food matrix, research clarifying all variables involving this food are essential. This study aimed to verify the occurrence of Campylobacter spp., identify thermophilic species involved and assess the level of antimicrobial susceptibility of isolates from chicken carcasses and eggs obtained from commercial establishments in the city of Goiânia. A total of 100 chicken carcasses and 100 dozens of eggs were evaluated using enzyme- linked immunosorbent assay for screening miniVIDAS ® with subsequent bacterial isolation and identification of samples by biotyping . By means of the methods employed observed that Campylobacter spp. was identified in 7% (7 /100) of chicken carcasses in 1% (1/100 ) of samples of eggs, 100 % of these were confirmed as belonging to the bacterial genus . The species with the highest number of isolates were Campylobacter jejuni (50 %), followed by Campylobacter coli ( 25 % ) and Campylobacter lari ( 25 % ). For antimicrobial resistance results were that 100% of the isolates were resistant to erythromycin, as well as ciprofloxacin and tetracyclines. For ceftriaxone and nalidixic acid resistance values were 91.7 % resistant. Chloramphenicol was 50% of resistant isolates, showed 33.3% sensitivity and 16.7% intermediate resistance. It was also observed that 100% of the isolates showed multidrug profile. Through the results obtained it is concluded that thermophilic Campylobacter are present in chicken carcasses and marketed in Goiânia eggs, whose distribution becomes relevant from the point of view of exposure to consumers. Campylobacter jejuni was the most frequent species. The six districts surveyed had bacteria of the genus in at least one category. Isolates when screened for response to antimicrobial proved multiresistant, denoting the importance of research as a way to support the election of bases and principles for the antibiotic treatment prescribed treatments. Poultry foods surveyed in this study and considered positive for the pathogen constitute risk to the consumer.

Ao ser ingerido mesmo em pequenas quantidades (de 400 a 500 células), esse microrganismo, por meio dos mecanismos de patogenicidade, desenvolve gastroenterite infecciosa no hospedeiro, conhecida como campilobacteriose. Esta doença está intimamente relacionada à ingestão e manipulação incorreta de alimentos contaminados, especialmente carne de frango, sendo as aves o principal reservatório. Pouco se sabe sobre o papel desempenhado pelos ovos na transmissão de campilobacteriose, tendo como base o consumo anual dessa matriz alimentar, pesquisas que esclareçam todas as variáveis envolvendo esse alimento são de fundamental importância. Pelo exposto, este estudo teve como objetivo verificar a ocorrência de Campylobacter spp., identificar as espécies termotolerantes circulantes na cidade de Goiânia, vinculadas aos estabelecimentos comercializadores de alimentos, relacionados à alta densidade populacional, localizados em distritos comerciais e avaliar o nível de suscetibilidade a antimicrobianos dos isolados de carcaças de frango e ovos provenientes destes estabelecimentos. Um total de 100 carcaças de frango e 100 dúzias de ovos foram avaliados utilizando como triagem o ensaio imunoenzimatico miniVIDAS® com posterior isolamento bacteriano das amostras e identificação por meio da biotipificação. Por meio dos métodos empregados observou-se que Campylobacter termotolerantes foi identificada em 7% (7/100) das carcaças de frango e em 1% (1/100) das amostras de ovos. A espécie com maior número de isolados foi Campylobacter jejuni (50%), seguidos por Campylobacter coli (25%) e Campylobacter lari (25%). Para a resistência à antimicrobianos os resultados reportaram que 100% dos isolados são resistentes à eritromicina, assim como à ciprofloxacina e tetraciclina. Para ácido nalidixico e ceftriaxona, os valores de resistência foram da ordem de 91,7%. Cloranfenicol foi resistente em 50% dos isolados, apresentou sensibilidade a 33,3% e resistência intermediária a 16,7%. Observou-se ainda que 100% dos isolados apresentaram perfil de multirresistência. Pelos resultados obtidos conclui-se que Campylobacter termotolerantes estão presentes em carcaças de frango e ovos comercializados na cidade de Goiânia, cuja distribuição torna-se relevante do ponto de vista da exposição aos consumidores. Campylobacter jejuni foi a espécie mais frequente. Os seis distritos pesquisados apresentaram bactérias do gênero pelo menos em um estabelecimento. Os isolados quando pesquisados quanto a resposta a antimicrobianos mostraram-se multirresistentes, denotando a importância desta investigação como forma de respaldar a eleição de bases e princípios para a antibioticoterapia para tratamentos prescritos. Os alimentos avícolas pesquisados neste estudo e considerados positivos para o patógeno constituem risco ao consumidor.Submitted by Franciele Moreira (francielemoreyra@gmail.com) on 2017-10-10T15:52:13Z No. of bitstreams: 2 Dissertação - Julierme José de Oliveira - 2014.pdf: 1186561 bytes, checksum: ee682becf7a3d3796f34ba3239320262 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2017-10-11T10:53:29Z (GMT) No. of bitstreams: 2 Dissertação - Julierme José de Oliveira - 2014.pdf: 1186561 bytes, checksum: ee682becf7a3d3796f34ba3239320262 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2017-10-11T10:53:29Z (GMT).
