Background. Micromammals are reservoirs of zoonotic parasites such as viruses, bacteria, protozoans and helminths. Objective. To present a review of the published literature on the study of zoonotic (or potential zoonotic) parasites of micromammals in the Yucatan Peninsula (PYU), Mexico, conducted by research groups of the Campus de Ciencias Biológicas y Agropecuarias (CCBA) of the Universidad Autónoma de Yucatán (UADY). Main findings. Thirty-two scientific contributions published from January 2002 to May 2020 were identified. Parasites such as viruses (Flavivirus spp.), bacteria (Rickettsia spp., Leptospira spp.), protozoans (Trypanosoma cruzi, Toxoplasma gondii) and helminths (Hymenolepis spp., Hydatigera taeniaeformis), were studied. These parasites were identified in 15 micromammal species, including rodents Mus musculus, Rattus rattus (Muridae), Heteromys gaumeri (Heteromyidae), Peromyscus yucatanicus, Sigmodon toltecus, Ototylomys phyllotis and Mesocricetus auratus (Cricetidae), Sciurus yucatanensis (Sciuridae), the marsupial Didelphis virginiana (Didelphidae), the coati Nasua narica (Procyonidae), the grison Galictis vittata (Mustelidae), and the bats Artibeus jamaicensis, Chiroderma villosum, Glossophaga soricina (Phyllostomidae) and Pteronotus mesoamericanus (Mormoopidae). Implications. Micromammals from the PYU harbor several zoonotic parasites which represent a public health risk. Conclusion. Thirty-two studies have been published by researchers of the CCBA-UADY that have increased the knowledge of the eco-epidemiology of zoonotic parasites of micromammals in the PYU.

The aim of this editorial is to present a brief description of the Torque teno virus’ epidemiology and establish the actuality of their study in México. Also, we mentioned the studies made in México and Yucatán, specifically in the Center of Regional Research “Dr. Hideyo Noguchi” of the Autonomous University of Yucatán.El objetivo de esta editorial es presentar una breve descripción de la epidemiología del Torque teno virus, así como establecer la actualidad del escenario de su estudio en México.

El objetivo de la presente investigación fue estudiar la presencia de flavivirus en roedores de Yucatán, México, mediante una prueba de Reacción en Cadena de la Polimerasa (PCR), en su variante semi-anidada. Se capturaron 90 roedores (87 Rattus rattus, dos Heteromys gaumeri y un Mus musculus) y se les recolectó una muestra de sangre. Las 90 muestras de suero resultantes fueron agrupadas en 30 triadas (pooles). La PCR semianidada arrojó una frecuencia de positividad del 33.3% (10/30) The aim of this investigation was to study the presence of flaviviruses in rodents from Yucatan, Mexico, by the Polymerase Chain Reaction (PCR) in the semi-nested variant. Ninety rodents were captured (87 Rattus rattus, two Heteromys gaumeri and one Mus musculus), and blood samples were collected. The resulting serum samples were grouped into 30 triads (pools). The semi-nested PCR yielded a positivity frequency of 33.3% (10/30)
