Bioactivity of synthetic peptides from Ecuadorian frog skin secretions against , , and .

Chagas disease, leishmaniasis, and malaria are major parasitic diseases disproportionately affecting the underprivileged population in developing nations. Finding new, alternative anti-parasitic compounds to treat these diseases is crucial because of the limited number of options currently available, the side effects they cause, the need for long treatment courses, and the emergence of drug-resistant parasites. Anti-microbial peptides (AMPs) derived from amphibian skin secretions are small bioactive molecules capable of lysing the cell membrane of pathogens while having low toxicity against human cells.

Identification of human leukocyte antigen in precancerous and cancerous cervical lesions from Ecuadorian women.

Cervical cancer is the fourth most common type of cancer in women. Worldwide, it is a public health problem with around 604,127 women diagnosed per year and 341,831 deaths. Cervical cancer and persistent high-risk human papillomavirus (HPV) infection are highly associated.

Nontyphoidal in Food from Latin America: A Systematic Review.

In Latin America, nontyphoidal (NTS) is one of the most important etiological agents of foodborne infections; it can survive in soil, water, and food even after processing. Here, we aimed to perform a systematic review by collecting data on the prevalence, serotypes, and antimicrobial resistance (AMR) of NTS isolated from different food products in Latin America, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Out of 1766 studies screened, 244 reports from 13 Latin American countries were eligible.

Molecular phylogeny of 42 species of Culicoides (Diptera, Ceratopogonidae) from three continents.

The genus Culicoides includes vectors of important animal diseases such as bluetongue and Schmallenberg virus (BTV and SBV). This genus includes 1300 species classified in 32 subgenera and 38 unclassified species. However, the phylogenetic relationships between different subgenera of Culicoides have never been studied.
