“…Therefore, gastropod eradication in the parks becomes important. Columbiformes are known to be the main hosts for P. bragai (PINTO et al, 2004;UNWIN et al, 2013) because they are synanthropic and lead to important diseases (ROCHA-E-SILVA et al, 2014). Special attention is needed in drawing up strategies for avoiding accidental risks relating to introduction of trematodes and diseases caused by them within wildlife parks, so as to keep hatcheries safe.…”

The aim of this study was to provide the first report on a new host for the digenean Paratanaisia bragai in the caninde macaw Ara ararauna along with the pathological aspects of the infection in the new host. The microscopic findings revealed the presence of granulomatous interstitial nephritis. This study contributes towards knowledge of parasitism by P. bragai in A. ararauna, and emphasizes the need to use best practices in wildlife conservation parks.Keywords: Parasite, birds, histopathology, wildlife, macaw. ResumoO objetivo deste estudo foi relatar, pela primeira vez, a arara canindé Ara ararauna como um novo hospedeiro para o digenético Paratanaisia bragai, bem como relatar aspectos patológicos relacionados à infecção no novo hospedeiro. Os achados microscópicos revelaram nefrite intersticial granulomatosa. Este estudo contribui para o conhecimento do parasitismo por P. bragai em A. ararauna e ainda faz um alerta para a adoção de boas práticas de criação em criatórios conservacionistas da fauna silvestre.

“…Pigeons ( Columba livia ) have contact with sewage and faeces from other animals, and antimicrobial residues in the environment (Faria et al, 2010; Wellington et al, 2013). In addition, they cohabit with humans in urban areas, being a potential public health risk (Faria et al, 2010; Rocha‐e‐Silva et al, 2014). An attractive model for studying bacterial resistance in pigeons is Escherichia coli , which belongs to the Enterobacteriales order.…”

Bacterial resistance is a public and one health problem. Free‐living birds can be reservoirs of multidrug‐resistant bacteria and resistance genes. This study aimed to characterize the antimicrobial resistance of Escherichia coli isolated from free‐living urban pigeons (Columba livia) in South Brazil. Ninety‐two animals were sampled, and one isolate was obtained from each one. The isolates were characterized, and the antimicrobial resistance profile and beta‐lactam and colistin resistance genes were investigated. The isolates were classified as phylogroups B1 (35%), B2 (33%), A (16%) and D (16%), and 14% of the strains had the eae virulence gene. All isolates were resistant to at least one antimicrobial, and 63% of them were multidrug‐resistant. Geographical location where the pigeons were captured and presence of the eae gene were associated with multidrug resistance. blaVIM and mcr‐1 genes were detected in one and two isolates, respectively. This is the first report of these genes in E. coli of pigeons. The blaVIM‐positive isolate was classified as Shiga toxin‐producing E. coli, and the isolates with mcr‐1 were classified as Enterohaemorrhagic E. coli and Enteropathogenic E. coli, which raise additional concerns related to public health since these are zoonotic pathotypes. The results reveal that pigeons carry multidrug‐resistant pathogenic E. coli, which may interest public health. Nonetheless, further studies on whether these animals are sources of contamination for humans must be performed to understand their role in spreading antimicrobial resistance.

Pigeons are known for their capacity to harbor and spread several zoonotic agents. Studies have suggested that pigeons are also relevant disseminators of multidrug-resistant strains. In this study, pigeons surrounding a veterinary hospital were sampled and tested for the presence of pathogenic Escherichia coli, Salmonella spp., Staphylococcus spp., and Clostridioides (Clostridium) difficile. E. coli isolates from 19 (40.4%) pigeons tested positive for the E. coli heat-stable enterotoxin 1 (EAST1)-encoding gene. The intimin-encoding gene (eae) of enteropathogenicE. coli (EPEC) was found in one isolate (2.1%). Salmonella spp. were found in nine (19.1%) pigeons, all from the first capture event (P < 000.1). S. Typhimurium and S. Heidelberg were isolated from six and three pigeons, respectively. Enterobacterial repetitive intergenic consensus (ERIC-PCR) of the Salmonella spp. isolates suggested that eight of the nine strains had a high genetic similarity, supporting the hypothesis of an outbreak of salmonellosis in these pigeons. Twenty (42.5%) staphylococcal isolates were recovered from 18 (38.3%) pigeons. Eight different species were detected, with S. xylosus being the most frequent. Two (4.3%) C. difficile strains were isolated. Three isolates, one each of S. Typhimurium, S. aureus, and C. difficile, were classified as multidrug-resistant strains. The present research suggested that pigeons residing in urban areas can act as reservoirs and disseminators of pathogenic bacteria, including nosocomial pathogens, such as diarrheagenicE. coli and multidrug-resistant Staphylococcus spp., C. difficile, and Salmonella spp.
