En este trabajo se presenta la detección de leptospiras patógenas en muestras ... -
Molecular characterization and antimicrobial resistance profiles of Salmonella Heidelberg isolates from poultry
(Wiley, 2021-02)In the last 10 years, Salmonella Heidelberg has been extensively isolated from poultry in several countries. In this context, molecular characterization is essential to understand whether the strains have entered the farms ... -
Molecular evidence of Leishmania spp. in spider monkeys (Ateles geoffroyi) from The Tuxtlas Biosphere Reserve, Veracruz, Mexico
(Springer, 2021-10)The black-handed spider monkey (Ateles geoffroyi) is a platyrrhine primate distributed in southern Mexico, Central America, and part of South America. Two subspecies inhabit Mexico: Ateles geoffroyi vellerosus and Ateles ... -
Dynamics of the ruminal microbial ecosystem, and inhibition of methanogenesis and propiogenesis in response to nitrate feeding to Holstein calves
(Elsevier, 2021-12)It is known that nitrate inhibits ruminal methanogenesis, mainly through competition with hydrogenotrophic methanogens for available hydrogen (H2) and also through toxic effects on the methanogens. However, there is limited ... -
Use of the Leptospira sp. ligB C-terminus coding region as a diagnostic tool of animal leptospirosis
(Elsevier, 2021-10)Leptospirosis is the most widespread zoonosis worldwide, and it can cause reproductive failures in livestock, while in humans may vary from a mild fever to multi-organ failure and death. Due to this, in this study, we ... -
Comparison of ELISA using recombinant LipL32 and sonicated antigen of leptospira for detecting bovine leptospirosis
(Elsevier, 2022-01)Leptospirosis is one of the most widely distributed zoonosis in the world. Bovine leptospirosis is a serious problem in bovine production, causing reproductive losses. The aim of this work was to compare recombinant LipL32 ... -
In vivo neutralization of bee venom lethality by IgY antibodies
(Elsevier, 2021-07)Bee venom is a complex mixture of molecules, among which melittin and phospholipase A2 (PLA2) are the toxic components involved in envenoming accidents with multiple honeybee stings. Traditionally, the treatment of envenomings ... -
N-Glycosylation in piroplasmids : Diversity within simplicity
(MDPI, 2021-01)N-glycosylation has remained mostly unexplored in Piroplasmida, an order of tick-transmitted pathogens of veterinary and medical relevance. Analysis of 11 piroplasmid genomes revealed three distinct scenarios regarding ... -
Evaluation of the safety profile of the vaccine candidate Brucella melitensis 16MDvjbR strain in goats
(Elsevier, 2021-01)Small ruminant brucellosis is caused by the Gram negative cocci-bacillus Brucella (B.) melitensis, the most virulent Brucella species for humans. In goats and sheep, middle to late-term gestation abortion, stillbirths and ... -
Changes in hematological, biochemical, and blood gases prameters in response to progressive inclusion of nitrate in the diet of Holstein calves
(Veterinary World Publisher, 2021-01)Background and Aim: Nitrate (NO3-) reduces enteric methane emissions and could be a source of non-protein nitrogen in ruminant feeds. Nonetheless, it has a potential toxic effect that could compromise animal health and ... -
Characterization of innate immune response to Brucella melitensis infection in goats with permissive or restrictive phenotype for Brucella intramacrophagic growth
(Elsevier, 2021-04)Caprine brucellosis is a chronic, world-wide distributed disease which causes reproductive failure in goats and Brucella melitensis, its causative agent, bears a great zoonotic potential. There is evidence suggesting that ... -
