Article Synopsis
- Rotavirus species A (RVA) significantly contributes to acute gastroenteritis in both humans and various animals, including rabbits, but detailed genetic studies on rabbit strains are limited.
- A new rotavirus strain (C-3/15) identified from a Mexican commercial rabbitry outbreak revealed a G3 P[8] genotype, which hasn't been previously reported in rabbits and shows close genetic ties to human rotaviruses.
- This finding suggests possible interspecies transmission of rotaviruses, marking the first molecular study of RVAs in rabbits in Mexico and highlighting the presence of human-associated genotypes in a rabbit with enteric disease.
Introduction: Endoparasites and ectoparasites in dogs are of global distribution. The close relationship between dogs and man implies a risk for the transmission of zoonotic parasites. Therefore, it is necessary to determine the parasites hosted by dogs in specific areas and the factors associated with their presence.

- Enteric diseases in livestock, such as coccidiosis caused by Eimeria spp., significantly impact productivity and cause economic losses due to high mortality and decreased growth rates.
- The study aimed to identify the eleven Eimeria species affecting sheep in the southeastern State of Mexico, using morphological techniques and partial sequencing of the ITS-1 rRNA region.
- The findings revealed phylogenetic connections between Eimeria species in sheep and those in other animals and proposed a new diagnostic method with implications for understanding ovine coccidial infections.
Urinary bladder worm infection is relatively uncommon in pet dogs and cats in the Americas. This report describes the diagnosis of lower urinary tract infection by Pearsonema plica in two asymptomatic dogs and P. feliscati in a cat with lower urinary tract clinical signs diagnosed between 2002 and 2015, and the first report of this type of parasitism in domestic small animals in Mexico at an altitude above 2600 m above sea level.

- This report marks the first identification of canine rotavirus in Mexico based on an analysis of 50 dog samples with gastroenteritis.
- The study used advanced techniques like polymerase chain reaction to detect the presence of rotavirus and parvovirus.
- Findings revealed that 7% of the dogs were solely infected with rotavirus, while 14% had both infections, with co-infected dogs showing more severe clinical symptoms.
