“…Hygienic measures in low socio-economic localities maximizing the common routes of transmission for campylobacteriosis by fecal-oral, person-to-person, ingestion of contaminated food and waterborne, contact with contaminated poultry, livestock or household pets, especially feces from puppies, kittens and birds (Humphrey et al, 2007).…”

“…Poultry has been recognized as the primary reservoir of C. jejuni thus, most of the campylobacteriosis infections are acquired by the consumption and/or handling of contaminated poultry meat (Malik et al, 2014) also consumption of unpasteurized milk, contaminated water, untreated surface water and meat rather than human to human transfer are considered as source of human infection by Campylobacter (Humphrey et al, 2007). The incubation period of Campylobacter jejuni microorganism typically varies from one to seven days (Butzler, 2004).…”

Several Campylobacter species are known to be pathogenic to humans, with Campylobacter jejuni being the main leading cause of campylobacteriosis worldwide. The present investigation aimed to detect C. jejuni from chicken, water, milk and milk products and humans among 4 Egyptian Governorates (Cairo, Fayoum, Minya and Qalubiya) using conventional method and PCR 146 C. jejuni isolates with an incidence of 6.2% were confirmed to species level by polymerase chain reaction through detection of MapA gene. high incidence of C. jejuni was recorded in chicken intestine (12.8%) followed by Chicken farms water (12%), raw chicken meat (9.6%), occupational human workers stool samples (8.4%) then raw milk (2%), Quraish cheese (1.7%) and finally it was 1.2% in yoghourt. The PCR was definitive, reliable method that facilitated rapid identification of C. jejuni to the species level. It concluded that poor hygiene and sanitation in poultry farms could explain this high level of prevalence of C. jejuni among the examined samples.

“…Estima-se que entre 50 e 80% das infecções em humanos teria origem avícola, sendo aves e produtos derivados considerados fontes primárias de campilobacteriose (1,5) . Apesar de serem termofílicas em seus requisitos de crescimento, C. jejuni e C. coli não resistem a altas temperaturas e, consequentemente, não sobrevivem em alimentos pasteurizados ou adequadamente cozidos (6) , além de serem sensíveis à dessecação (7) .…”

ResumoEspécies de Campylobacter spp. termotolerantes são agentes de surtos de campilobacteriose em humanos e os produtos de origem avícola são considerados uma importante fonte de infecção. Foram identificados Campylobacter jejuni e Campylobacter coli em carcaças de frango resfriadas e congeladas coletadas em três abatedouros entre 2014 e 2015. A detecção de Campylobacter spp. foi realizada por microbiologia convencional e a identificação de C. jejuni e C. coli por multiplex-PCR. Dentre as amostras avaliadas verificou-se Campylobacter spp. termotolerante em 63,8%, sendo 72,2% em carcaças resfriadas e 55,5% em carcaças congeladas. Destas, 83,3% foram positivas para C. jejuni e 66,6% para C. coli, enquanto 50% foram positivas para ambas as espécies. A presença de Campylobacter spp. termotolerante em carcaças de frangos de corte prontas para consumo representa uma importante fonte de transmissão destes patógenos para humanos. Palavras-chave: abatedouros avícolas; campilobacteriose; termotolerantes. AbstractSpecies of thermophilic Campylobacter spp. are agents of campylobacteriosis outbreaks in humans, and poultry products are implicated as major sources of infection. The detection of Campylobacter spp. was performed by conventional microbiology in poultry carcasses collected in slaughterhouses and species were identified by multiplex-PCR. Thermophilic Campylobacter spp. was verified in 63.8% of the samples, being 72.2% in chilled carcasses and 55.5% in frozen carcasses. Of these, 83.3% were positive for C. jejuni and 66.6% to C. coli, while 50% were positive for both. The presence of thermophilic Campylobacter spp. in ready-to-eat poultry products represents a potential source of human campylobacteriosis.

“…Campylobacter is the most common zoonotic cause of bacterial gastroenteritis in the industrialized world with the financial burden estimated at £500 million in the United Kingdom (Humphrey et al 2007) and $8 billion in the United States (Buzby and Roberts 1997). Human campylobacteriosis occurs after consumption of contaminated meat, water and milk (Friedman et al 2000;Kapperud et al 2003;Neimann et al 2003), and poultry meat is implicated as the major source of disease, accounting for 40-80% of cases (Corry and Atabay 2001;Vellinga and Van Loock 2002;Neimann et al 2003;Friedman et al 2004;Wilson et al 2008;Sheppard et al 2009a).…”

Aims-Crates used to transport live poultry can be contaminated with Campylobacter, despite periodic sanitization, and are potential vectors for transmission between flocks. We investigated the microbial contamination of standard and silver ion containing crates in normal use and the genetic structure of associated Campylobacter populations.Methods and Results-Bacteria from crates were enumerated by appropriate culture techniques, and multilocus sequence typing (MLST) was used to determine the genetic structure of Campylobacters isolated from standard and silver ion containing crates. Compared to standard crates, counts of bacteria, including Campylobacter, were consistently lower on silver ion containing crates throughout the decontamination process. In total, 16 different sequence types were identified from 89 Campylobacter jejuni isolates from crates. These were attributed to putative source population (chicken, cattle, sheep, the environment, wild bird) using the population genetic model, STRUCTURE. Most (89%) were attributed to chicken, with 22% attribution to live chicken and 78% to retail poultry meat. MLST revealed a progressive shift in allele frequencies through the crate decontamination process. Campylobacter on crates survived for at least 3 h after sanitization, a period of time equivalent to the journey from the processing plant to the majority of farms in the catchment, showing the potential for involvement of crates in transmission.Conclusions-Inclusion of a silver ion biocide in poultry transportation crates to levels demonstrating acceptable antibacterial activity in vitro reduces the level of bacterial contamination during normal crate use compared to standard crates. Molecular analysis of Campylobacter isolates indicated a change in genetic structure of the population with respect to the poultryprocessing plant sanitization practice.Significance and Impact of the Study-The application of a sustainable antimicrobial to components of poultry processing may contribute to reducing the levels of Campylobacter circulating in poultry.
