Members of the subgenus Herpetosoma are specialized parasites of mammals of the order Lagomorpha and Rodentia. It is estimated that around 50 species within this subgenus are transmitted by several flea species. These parasites have recently gained attention from a public health perspective because several species have been reported to infect humans.

The monthly fluctuation of adult Ixodes keiransi in dogs from two cattle farms in southeastern Mexico was determined. In ranch 1 (R1), 6-7 mixed breed dogs from six months to five years of age; while in ranch 2 (R2), 7-8 mixed breed dogs from one to four years of age, were followed. All dogs were monthly inspected for tick infestation through one year.

Article Synopsis
  • Ticks, particularly from the Ixodes genus, are blood-feeding ectoparasites with at least 245 species, and the Ixodes affinis has a broad distribution from South America to the U.S.
  • This study aims to explore the genetic diversity of I. affinis across the Americas, especially in areas where data is sparse, and to clarify its taxonomy, suggesting it may represent a complex of four distinct species.
  • The research involved collecting samples from South Carolina and Yucatán, resulting in significant genetic structure findings that support the idea that I. affinis consists of several closely related species.

Bats are one of the groups of mammals with the highest number of associated Trypanosoma taxa. There are 50 Trypanosoma species and genotypes infecting more than 75 species of bats across five continents. However, in Mexico, the inventory of species of the genus Trypanosoma associated with bats is limited to only two species (Trypanosoma vespertilionis and Trypanosoma cruzi) even though 140 species of bats inhabit this country.

Article Synopsis
  • - The study investigates the presence of Leptospira bacteria in small mammals (bats and rodents) captured in Yucatan, Mexico, and examines how the environment at capture sites affects this occurrence.
  • - A total of 82 bats and 78 rodents were studied, revealing a combined Leptospira infection rate of 21.2%, with slightly higher rates in bats (21.9%) compared to rodents (20.5%).
  • - The research identified the main Leptospira species as L. borgpetersenii and L. noguchii, and found that sites with tropical deciduous forests had more infected rodents, while those with tropical sub-deciduous forests had greater diversity in infected bats.*
