The aim of this study was to investigate whether Trypanosoma vivax is transmitted via rectal palpation in cattle, using the same glove with different blood scores, from an animal with an acute infection of this protozoan. In addition, the efficacy of iodine as disinfectant, together with water with or without the presence of feces, to prevent the transmission of T. vivax in cattle during the rectal palpation process was evaluated in the laboratory and animals.

Reactivation of Trypanosoma cruzi transmission by native vectors with different domiciliation capabilities is a major concern for Chagas disease control programs. T. cruzi transmission via intra-domestic Rhodnius prolixus was certified as interrupted by the Pan American Health Organization in Miraflores municipality (Boyacá, Colombia) in 2019.

Morphometry is an effort to describe or measure the morphology of the body, or parts of it. It also provides quantitative data on the interactions of living organisms with their environment, external or internal. As a discipline, morphometrics has undergone significant developments in the last decade, making its implementation more visual and less laborious.

Hemoparasitic diseases represent a significant problem with a considerable impact on tropical and subtropical areas of the world. These conditions cause economic losses associated with multi-organic failure and even the death of animals. In these areas, the hemoparasites are transmitted in an enzootic cycle when infectious cattle, such as persistently infected animals, including cows, contribute to the success of transmission.

The primary mode of transmission for Chagas disease is vector-borne transmission, spread by hematophagous insects of the subfamily. In Mexico, the triatomine is particularly significant in the transmission of . This study focused on analyzing protein expression and modifications by glycosylation in different regions of the digestive tract of fifth-instar nymphs of .
