Abstract
Salmonella enterica subspecies arizonae (subspecies IIIa) is most frequently associated with reptiles but is also a bacterial pathogen of poultry, primarily of young turkeys where it induces septicemia, neurologic signs, and increased mortality. Arizonosis clinical cases in broiler chickens have recently been documented in the United States, driving the development of a rapid, molecular-based diagnostic for this subspecies. S. enterica subsp. arizonae is a genetically distinct subgroup of S. enterica, primarily diagnosed through culture followed by serotyping or biochemical identification, which are costly in both time and laboratory resources. Real-time/quantitative PCR offers rapid and sensitive detection of Salmonella sp. in laboratory and diagnostic samples; however, no such methodology exists to differentiate S. enterica subsp. arizonae from other Salmonella sp. In this study, we designed a quantitative PCR assay for S. enterica subsp. arizonae. The assay is able to differentiate S. enterica subsp. arizonae from other S. enterica subspecies, including S. enterica subsp. diarizonae (IIIb), and other non-Salmonella bacteria. Validation, including 56 different S. enterica subsp. arizonae serovars, demonstrated 100% sensitivity and 100% specificity. This assay provides a rapid diagnostic option for suspected cases of arizonosis in poultry.

Abstract
Wild birds is one of the reservoir agent of some of various zoonotic diseases. The study was aim to see the potential of sparrow as the reservoir agent of Salmonella sp. using polymerase chain reaction (PCR) method. We detected the invA gene of Salmonella sp. from faecal sample of sparrows (Passer domesticus) in local area of Yogyakarta, Indonesia. A total of 30 faecal dropping samples were collected from sparrows. DNA was extracted from the faecal samples, then amplified by PCR for the target genes. The amplicons were electrophorized to see the visualization of DNA on the agarose gel. The result showed the prevalence of the positive result of Salmonella sp. was 3,3%. The study indicated that sparrows can spread zoonotic pathogens and this necessitates monitoring for the epidemiologic status of these pathogens among birds, also applying the appropriate intervention measures to prevent the transmission of zoonotic diseasesfrom birds to humans.

Abstract
AbstractOccurrence of Salmonella spp. in captive wild animal species in India is largely unknown. The purpose of this study was to determine the occurrence of different Salmonella serotypes, antimicrobial resistance patterns and genotypic relatedness of recovered isolates. A total of 370 samples including faecal (n = 314), feed and water (n = 26) and caretakers stool swabs (n = 30) were collected from 40 different wild animal species in captivity, their caretakers, feed and water in four zoological gardens and wildlife enclosures in India. Salmonellae were isolated using conventional culture methods and tested for antimicrobial susceptibility with the Kirby–Bauer disc diffusion method. Salmonella isolates were serotyped and genotyping was performed using enterobacterial repetitive intergenic consensus (ERIC) PCR and 16S rRNA sequencing. Animal faecal samples were also subjected to direct PCR assay. Salmonella was detected in 10 of 314 (3.1%) faecal samples by isolation and 18 of 314 (5.7%) samples by direct PCR assay; one of 26 (3.8%) feed and water samples and five of 30 (16.7%) caretakers stool swabs by isolation. Salmonella was more commonly isolated in faecal samples from golden pheasants (25%; 2/8) and leopard (10%; 2/20). Salmonella enterica serotypes of known public health significance including S. Typhimurium (37.5%; 6/14), S. Kentucky (28.5%; 4/14) and S. Enteritidis (14.3%; 2/14) were identified. While the majority of the Salmonella isolates were pan-susceptible to the commonly used antibiotics. Seven (43.7%; 7/16) of the isolates were resistant to at least one antibiotic and one isolate each among them exhibited penta and tetra multidrug-resistant types. Three S. Kentucky serotype were identified in a same golden pheasants cage, two from the birds and one from the feed. This serotype was also isolated from its caretaker. Similarly, one isolate each of S. Typhimurium were recovered from ostrich and its caretaker. These isolates were found to be clonally related suggesting that wildlife may serve as reservoir for infections to humans and vice versa. These results emphasise the transmission of Salmonella among hosts via environmental contamination of feces to workers, visitors and other wildlife.

Abstract
RESUMO As doenças infecciosas são reconhecidamente causadoras de declínios populacionais de animais silvestres e algumas delas podem representar ameaça à saúde pública. O presente estudo objetivou investigar a ocorrência de Salmonella spp. em Psittaciformes exóticos e nativos mantidos em cativeiro na região central do Rio Grande do Sul, além de comparar os resultados obtidos por meio do método bacteriológico convencional e da reação em cadeia da polimerase (PCR), mediante a utilização de material fecal do ambiente, evitando-se o estresse da contenção. Durante os meses de agosto/2016 e setembro/2016 foram coletadas amostras de fezes frescas de 90 gaiolas em dois criatórios, representando 180 aves. Com as duas técnicas empregadas nas análises, as amostras foram negativas para Salmonella spp., contudo foram detectadas bactérias da família Enterobacteriaceae: Escherichia coli, Cedecea sp. e Citrobacter freundii. Considera-se importante a continuidade do monitoramento dos criatórios, já que o patógeno investigado pode estar em aves portadoras e se manifestar em situações de estresse, representando riscos enquanto zoonose e prejuízos à saúde das aves.

Abstract
RESUMO: O tráfico de animais selvagens consiste numa atividade ilegal exercida em diversas partes do mundo, e o Brasil, em função de sua grande extensão territorial e vasta biodiversidade, é um país bastante atingido por essa prática. O grupo de animais em perigo que mais se destaca é o das aves e, entre elas, as da ordem Psittaciformes. Essas são as mais traficadas por serem consideradas inteligentes e possuidoras de grandes habilidades de comunicação. Por isso, são retiradas indiscriminadamente da natureza. No entanto, as condições em que essas aves são capturadas e mantidas em cativeiro favorecem o aparecimento de diversas enfermidades, entre elas as causadas pelas enterobactérias. As bactérias que mais causam mortes e problemas em psitacídeos são as do gênero Salmonella e Escherichia coli , responsáveis pela salmonelose e pela colibacilose, respectivamente. Este trabalho apresenta uma revisão da literatura sobre essas enterobactérias em Psittaciformes, ressaltando o potencial zoonótico desses agentes.

Abstract
Abstract: The Enterobacteriaceae family contains potentially zoonotic bacteria, and their presence in canaries is often reported, though the current status of these in bird flocks is unknown. Therefore, this study aimed to identify the most common genera of enterobacteria from canaries (Serinus canaria) and their antimicrobial resistance profiles. From February to June of 2013, a total of 387 cloacal swab samples from eight domiciliary breeding locations of Fortaleza city, Brazil, were collected and 58 necropsies were performed in canaries, which belonged to the Laboratory of Ornithological Studies. The samples were submitted to microbiological procedure using buffered peptone water and MacConkey agar. Colonies were selected according to their morphological characteristics on selective agar and submitted for biochemical identification and antimicrobial susceptibility. A total of 61 isolates were obtained, of which 42 were from cloacal swabs and 19 from necropsies. The most isolated bacteria was Escherichia coli with twenty five strains, followed by fourteen Klebsiellaspp., twelve Enterobacterspp., seven Pantoea agglomerans, two Serratiaspp. and one Proteus mirabilis. The antimicrobial to which the strains presented most resistance was sulfonamides with 55.7%, followed by ampicillin with 54.1% and tetracycline with 39.3%. The total of multidrug-resistant bacteria (MDR) was 34 (55.7%). In conclusion, canaries harbor members of the Enterobacteriaceae family and common strains present a high antimicrobial resistance rate, with a high frequency of MDR bacteria.
