“…Although research on the occurrence of Leptospira spp. in the species studied is still in the early stages, some studies (ANDREWS et al, 1965;DEZZUTTO et al, 2017;GLOSSER et al, 1974;GRIMM et al, 2015;OLIVEIRA et al, 2016) have indicated that chelonians can serve as possible reservoirs of these agents, showing high prevalence rates similar to those detected of the present study.…”

Leptospirosis is a zoonosis of worldwide distribution in which the agent can infect several animal species and accidentally humans. In view of the limited number of studies on anti-Leptospira antibodies in wild animal species, especially those living in aquatic environments, we sought in this study to investigate the presence of these antibodies in the spot-legged turtle (Rhinoclemmys punctularia) maintained in captivity in the Rodrigues Alves Botanical Garden-Amazon Zoobotanical Park, located in Belém, Pará State, Brazil. Serum samples were collected from 31 turtles, and identification of anti-Leptospira antibodies was performed using the microscopic agglutination test, using a collection of 31 live antigens which represent 19 serogroups of Leptospira. Among the analyzed samples, 54.83% (17/31) were observed to be reactive, and co-agglutination was detected in a further six samples which were not accounted for in the frequency of serogroups. The most frequently detected serogroups were Tarassovi 72.72% (8/11), Celledoni 18.18% (2/11), and Pomona 9.09% (1/11)], with titers ranging from 200 to 400, being this the first study to report infection of these serogroups in this species of chelonios. The animals were kept in water tanks, which probably favored the transport of the agent and allowed its transmission to the spot-legged turtle. We thus confirmed presence of anti-Leptospira antibodies in chelonians maintained in the Rodrigues Alves Botanical Garden.

“…Many domestic and wild mammals have been found to be either natural reservoirs or accidental hosts for several serotypes of Leptospira spp. However, non-mammalian animals such as those belonging to the herpetofauna (Andrews et al, 1965;Jobbins and Alexander, 2015) may play a role as reservoir hosts when considering the epidemiology (Glosser et al, 1974), transmission and persistence of Leptospira spp. (Jobbins and Alexander, 2015).…”

Detection of Leptospira spp. in wild Phrynops geoffroanus (Geoffroy’s side-necked turtle) in urban environment

Leptospira spp., a zoonotic agent relevant for public health, occurs frequently in tropical regions. The aquatic environment represents a viable survival and transmission pathway. This study aimed to investigate the presence of anti-Leptospira spp. antibodies in Phrynops geoffroanus (Geoffroy's side-necked turtle) serum samples using the microagglutination test (MAT), and Leptospira spp. in gastric and cloacal lavage samples using the polymerase chain reaction (PCR) technique. Antibodies against nine different Leptospira spp. serovars were detected in 45.45% (30/66) of the serum samples. Specific amplification of Leptospira spp. genomic material (331bp) was observed in 16.67% (11/66) of the samples. In conclusion, these freshwater testudines host Leptospira spp. and eliminate them. This situation may represent a risk to public health, especially to people who use urban streams for fishing and recreational activities. Additionally, we described some Leptospira spp. serovars, not yet reported in testudines, detected here in P. geoffroanus.

“…Specific agglutinins were also found to serotype canicola in C. picta serum. Agglutinins to parasitic leptospires in lower vertebrate sera have been reported by others (2,9,23,26). However, these agglutinins may not be related to antibody and may not be epidemiologically related.…”

Normal serum from the painted turtle (Chrysemys picta), the snapping turtle (Chelydra serpentina), and the frog (Rana pipiens) were found to possess bactericidal activity towards Leptospira. Leptospires from both the parasitic and biflexa complexes were killed by these sera at high dilutions. This pattern differs from that of mammalian serum, as generally only the biflexa complex leptospires are killed by normal mammalian serum. The activity in C. picta serum was characterized as being complement dependent and not mediated by basic proteins. Because complement-inactivated C. picta serum regained leptospiricidal activity after the addition of fresh rabbit serum, antibody is also likely to participate in the killing activity. Further support that C. picta serum contained leptospiral antibodies was found by the detection of serotype-specific agglutinins.
