“…Enrofloxacin, gentamicin, and ciprofloxacin resistance were not detected in any of the pigeon-origin E. coli isolates. Interestingly, these results were found to be consistent with one study that analyzed the antibiotic susceptibility profile of E. coli isolates obtained from domestic pigeons (Columba livia domestica) in Turkey and reported 100% susceptibility to enrofloxacin and gentamicin [67]. Furthermore, Silva et al [62] reported 100% gentamicin susceptibility of pigeon-origin E. coli isolates, which is consistent with the findings of this study.…”

Background Curbing the potential negative impact of antibiotic resistance, one of our era's growing global public health crises, requires regular monitoring of the resistance situations, including the reservoir of resistance genes. Wild birds, a possible bioindicator of antibiotic resistance, have been suggested to play a role in the dissemination of antibiotic-resistant bacteria. Therefore, this study was conducted with the objective of determining the phenotypic and genotypic antibiotic resistance profiles of 100 Escherichia coli isolates of gull and pigeon origin by using the Kirby-Bauer disk diffusion method and PCR. Furthermore, the genetic relationships of the isolates were determined by RAPD-PCR. Results Phenotypic antibiotic susceptibility testing revealed that 63% (63/100) and 29% (29/100) of E. coli isolates were resistant to at least one antibiotic and multidrug-resistant (MDR), respectively. With the exception of cephalothin, to which the E. coli isolates were 100% susceptible, tetracycline (52%), kanamycin (38%), streptomycin (37%), ampicillin (28%), chloramphenicol (21%), trimethoprim/sulfamethoxazole (19%), gentamicin (13%), enrofloxacin (12%) and ciprofloxacin (12%) resistances were detected at varying degrees. Among the investigated resistance genes, tet(B) (66%), tet(A) (63%), aphA1 (48%), sul3 (34%), sul2 (26%), strA/strB (24%) and sul1 (16%) were detected. Regarding the genetic diversity of the isolates, the RAPD-PCR-based dendrograms divided both pigeon and gull isolates into five different clusters based on a 70% similarity threshold. Dendrogram analysis revealed 47–100% similarities among pigeon-origin strains and 40–100% similarities among gull-origin E.coli strains. Conclusions This study revealed that gulls and pigeons carry MDR E. coli isolates, which may pose a risk to animal and human health by contaminating the environment with their feces. However, a large-scale epidemiological study investigating the genetic relationship of the strains from a "one health" point of view is warranted to determine the possible transmission patterns of antibiotic-resistant bacteria between wild birds, the environment, humans, and other hosts.

“…The different isolation rates or diversity of species can be resulted from different breeding facilities, management procedures and environmental factors [2,4,[10][11][12][18][19][20] . The presence of VRE in companion animals is becoming a high clinical concern due to the high transmission risk of VRE via close contact with their owners.…”

Infections caused by Vancomycin Resistant Enterococci (VRE) are important in human medicine in terms of treatment difficulties. Molecular studies in the last years revealed that VRE occurrence in animals might be important in epidemiology of infections in human. This study aims to detect VRE occurrence in various animals, examine antibiotic resistance profiles phenotypically, and determine the distribution of the vancomycin resistant genes, vanA, vanB, vacC1, vanC2/C3. For this purpose, rectal swabs were collected from farm and companion animals; and cloacal swab or litter were collected from chickens and they were processed for VRE isolation. Following the identification of the isolates, antimicrobial susceptibilities of the isolates were determined in accordance with the Clinical and Laboratory Standards Institute (CLSI) standards. Distribution of the vancomycin resistant genes; vanA, vanB, vanC1 and vanC2/C3 among enterococcus species and different animal species were determined by multiplex PCR. VRE were isolated from 17% of the feline samples, 20% of each of the other species, and 19% of all the samples. Those isolates were identified as E. casseliflavus (n=39), E. gallinarum (n=55) and E. faecium (n=3) as a result of multiplex-PCR. According to the antimicrobial susceptibility tests, most of the isolates were found to be resistant to penicillin G, ciprofloxacin and erythromycin. Eighteen (18.8%) of the isolates were found to be resistant against two antibiotic groups, while 69 (71 %) of them were resistant to three or more antibiotics. Keywords

With their food and shelter seeking habits, pigeons are often found in places where humans are present. However, these shared spaces can host public health risks for the transmission of zoonoses. Therefore, we sought to explore the existing relationship between the presence of domestic pigeons (Columba livia) and self-perceived respiratory and skin morbidity in individuals in a neighborhood of Bogotá, Colombia. We conducted a cross-sectional neighborhood survey from February to May, 2014. Random and probabilistic sampling based on a list of dwellings was conducted. All of the dwellings in the neighborhood, as well as all the inhabitants at home during the survey, were included. A univariate and bivariate descriptive analysis was carried out, to establish statistical relationships based on use of the chi-square test and prevalence ratios. Also, a negative binomial regression model was used to determine the relationship between some pigeon exposures and the number of self-perceived symptoms. Respiratory and skin self-perceived symptoms were surveyed, along with the conditions in the dwellings and the presence of pigeons and their droppings. Altogether, 27.4% of those surveyed reported pigeon droppings within their dwellings or outside of them, and 33.1% stated they had experienced contact with pigeon droppings. The presence of sick pigeons around the houses was associated with self-reported headaches, rhinorrhoea and sneezing. Similarly, droppings inside dwellings were associated with a range of self-reported symptoms, such as fever, dry cough and sneezing. The self-perception of respiratory and skin symptoms, and their association with the presence of pigeons may indicate that zoonotic transmission of pathogens has occurred in the respondents, despite the limitations of the study. Contact with domestic Columba livia pigeons or their droppings has previously been identified as a transmission route for zoonotic microorganisms.
