“…in asymptomatic parrots under human care. Silva et al (2016), when analyzing 85 parrots of different species from a zoo in Pernambuco, reported the presence of Mycoplasma spp. in 16.47% of the birds, however these mycoplasmas were not identified as MG or MS. Carvalho et al (2017), when evaluating 300 samples of CETAS parrots, commercial and conservation breeding, observed positivity for M. gallisepticum (MG) in 21.6% (16/74) in CETAS, 15.7% (19/121) in commercial breeding, and 6.7% (7/105) in conservationist, while for MS the occurrences were 2.7 % (2/74) in CETAS, 0.0% (0/121) in commercial breeding and 1.9% (2/105) in conservationist.…”

Brazil is one of the countries with the most abundant avifauna in the world. The confinement of birds associated with close contact with other animals and humans favor the spread of agents of respiratory diseases. Among them, mycoplasmas can cause asymptomatic or apparent disease that manifests in birds by coughing, sneezing, rales, conjunctivitis, ocular and nasal discharge. Several described mycoplasmas cause disease in birds, especially Mycoplasma gallisepticum(MG) andMycoplasma synoviae(MS). The diagnosis ofMycoplasmaspp. can be done by clinical observation and laboratory analysis. Molecular diagnosis by PCR was boosted by its speed, sensitivity, and low cost of agent isolation techniques that take up to 21 days to complete. This study aimed to verify the occurrence ofMycoplasmaspp. in birds of the Rio de Janeiro Zoo (Rio Zoo), by isolation and PCR. Of the total 635 birds from the Rio Zoo, 81 were studied for detection ofMycoplasmaspp., when taken for routine health assessment exams. These birds belonged to the following orders: Psittaciformes (45), Accipitriformes (18), Galliformes (7), Piciformes (5), Strigiformes (4), Falconiformes (1) and Cariamiformes (1), all individuals already identified by microchip or leg-ring. There was no isolation of mycoplasmas in any of the samples tested, whereas, in the PCR, 62.96% (51/81) were positive, with 1.96% (1/51) identified as MG and 19.61% (10/51) as MS, representing 1.23% (1/81) and 12.34% (10/81) of the total population studied. PCR was shown to be a more effective technique than isolation in the detection ofMycoplasmaspp. in birds. It was possible to detect mycoplasmas in birds from Riozoo with no clinical respiratory signs, with higher MS prevalence than MG. The positivities forMycoplasmaspp., MS, and MG were different among the orders studied, being the highest occurrence in birds of prey, followed by Galliformes and Piciformes. The presence of MG and MS in birds of Rio de Janeiro Zoo confirms the circulation of these agents and the need for further studies on the dissemination of mycoplasmas in zoos for the epidemiological analysis of these bacteria in these places.

“…Difference in culture and PCR results can be explained by the number of mycoplasmas in the sample, occurrence of inhibitors or failure in the diagnostic method (Timenetsky et al, 2006). The presence of mycoplasmas in asymptomatic wild captive birds has already been reported in the study by Silva et al (2016) who observed a prevalence of 16.5% Mycoplasma spp. in 85 parrots and Carvalho et al (2017) who found percentages of 21.6%, 15.7% and 6.7% positivity in birds from, respectively, a Wild Animal Sorting Center, a commercial breeding site and a conservation breeding site and these results agree with what was found in our study.…”
