Resumen

Chlamydia is an intracellular bacterium that infects a variety of birds, reptiles, amphibians, and mammals, such as humans. Recently, new Chlamydia species have been identified in reptiles. In this study, 25 cloacal swabs and tissue samples were collected from reptiles in professional care in Mexico. Using endpoint PCR, the genome of Chlamydia spp., was detected in 20 % of the samples. Specifically, the presence of the Chlamydia spp., genome was detected by partial sequencing of the intergenic region of 16S-23S rRNA in cloacal swabs and tracheal tissue samples of the Mapimí desert tortoise (Gopherus flavomarginatus), revealing 95 % homology to Chlamydia spp. This study reports the first documented case of Chlamydia spp., in reptiles in professional care in Mexico. Chlamydia can threaten reptile populations. Therefore, further investigations are recommended to identify the circulating Chlamydia species in Mexico and evaluate their epidemiologic impact.
