Abstract

<p><strong>Background. </strong>In tropical and subtropical regions there are ideal conditions for the maintenance and proliferation of leptospirosis, toxoplasmosis, American trypanosomiasis, and heartworm disease, which affect the welfare and health of domestic and synanthropic animals and can cause zoonoses. <strong>Objective.</strong> To identify the main epidemiological findings of potentially zoonotic diseases such as leptospirosis, toxoplasmosis, American trypanosomiasis, and heartworm disease in domestic animals, synanthropics, and humans in the Yucatan Peninsula. <strong>Methodology.</strong> The compilation of scientific articles from the studies carried out by the academic body of Animal Health in the first 50 years of the Faculty of Veterinary Medicine and Animal Science of the Autonomous University of Yucatan was carried out. The review focused on four infectious agents with zoonotic potential (<em>Leptospira</em> spp,<em> Toxoplasma gondii</em>, <em>Trypanosoma cruzi</em>, and<em> Dirofilaria immitis</em>) that affect animals in the Yucatan peninsula. <strong>Results.</strong> The studies have shown a wide distribution of animals affected by these agents and described various aspects of epidemiology in animals and humans. <strong>Implications.</strong> Epidemiological monitoring of these agents and the study of their impact on health is essential for decision-making when it comes to implementing official control and prevention measures in both animals and humans. <strong>Conclusions.</strong> The infectious agents described (bacteria, protozoa and nematode) have a wide distribution in various species of domestic and synanthropic animals of the Yucatan peninsula, and have an impact on the human population in this region of Mexico. The epidemiological conditions described in this region should serve to prevent and control these diseases.</p>

Toxoplasmosis: comprensión de la respuesta inmunitaria que influye en la gravedad y la cronicidad de la infección

“…Por lo tanto, el enfoque del estudio se centró en el análisis de los principales de una prevalencia, baja (10-30%) en América del Norte, en algunos países del Sudeste Asiático, en Japón, en el norte de Europa y en las zonas sahelianas de África; tiene una prevalencia media (30-50%) en los países del centro y del sur de Europa; y las prevalencias más elevadas, a menudo superiores al 70%, están en regiones tropicales húmedas de los países de América Latina y África (A. Ortega-Pacheco et al, 2021). En la presente investigación realizada por Bernal, Juan (Bernal Santos, 2022) En Ecuador, se encontró que la seroprevalencia global de T. gondii era aproximadamente del 30% de la población humana.…”

TÉCNICA DE ABOMASOTOMÍA PARA LA EXTRACCIÓN DE Haemonchus contortus EN CABRAS VIVAS

“…In sheep, the laparoscopic abomasal cannulation has been described (Zhang et al, 2015) and used for abomasal biopsies in H. contortus infected sheep (Rowe et al, 2008). An abomasotomy technique was described to perform a monospecific artificial infection of H. contortus, by inserting adult worms into the abomasum of worm-free goats (Ortega-Pacheco et al, 2009). With that protocol the parasites' eggs were obtained from the infected animals in < 48 h postinfection.…”

“…(d) Infecting animals with adult worms. This protocol may be used to infect animals with adult worms as mentioned previously (Ortega-Pacheco et al, 2009). Animals infected with adult worms start excreting GIN eggs in the faeces as soon as 2 days post-surgery.…”
