Evaluation of a 70 kDa Excreted/Secreted Coproantigen Immunoassay for the Detection of in Dogs.

Background: We aimed to develop a sandwich ELISA, using polyclonal antibodies against excretory/secretory (E/S) antigens specific to coproantigens present in -positive dogs.

Methods: Antibodies were produced at Biological Sciences School, Autonomous University of Nuevo León, in 2023 by immunization of rabbits with antigenic extracts from in vitro cultures of larvae. Assays were performed on 100 stool samples from pet dogs, measuring sensitivity, specificity, and cross-reactivity against other parasitic infections.

In Vitro Antiprotozoal Activity of Extract, Partitions, and Fractions against .

Chagas disease, caused by the protozoan , represents an important and worldwide public health issue, particularly in Latin America. Limitations of conventional treatment with benznidazole and nifurtimox underscore the urgent need for new therapeutic strategies for this disease. , a tree used in traditional medicine for various ailments, has demonstrated promising antiparasitic activity.

Genomic Characterization of Sonora, a Strain with Inhibitory Activity against -AHPND and Probiotic Candidate for Shrimp Aquaculture.

Acute hepatopancreatic necrosis disease, caused by strains carrying the A and B toxin genes (VpAHPND), has been causing great economic losses in Asia and America in the shrimp farming industry. Numerous strains are resistant to antibiotics. However, supplementation with probiotic antagonists has become a more desirable treatment alternative.

Diversity of midgut microbiota in ticks collected from white-tailed deer (Odocoileus virginianus) from northern Mexico.

Ticks host different pathogens as endosymbiont and nonpathogenic microorganisms and play an important role in reproductive fitness and nutrient provision. However, the bacterial microbiomes of white-tailed deer ticks have received minimal attention. This study aimed to examine the bacterial microbiome of ticks collected from Odocoileus virginianus on the Mexico-United States border to assess differences in microbiome diversity in ticks of different species, sexes, and localities.

In vitro anti-Trypanosoma cruzi activity of methanolic extract of Bidens pilosa and identification of active compounds by gas chromatography-mass spectrometry analysis.

Chagas disease, caused by Trypanosoma cruzi parasite, is a significant but neglected tropical public health issue in Latin America due to the diversity of its genotypes and pathogenic profiles. This complexity is compounded by the adverse effects of current treatments, underscoring the need for new therapeutic options that employ medicinal plant extracts without negative side effects. Our research aimed to evaluate the trypanocidal activity of Bidens pilosa fractions against epimastigote and trypomastigote stages of T.
