Although has become one of the most important nosocomial pathogens worldwide, very little is known about the genetic identity of isolates from less developed countries in Latin America. To alleviate this, we sequenced the genomes of 16 isolates from Honduras. Whole-genome sequencing was conducted on 16 isolates from five Honduran Hospitals. With the sequences of these Honduran isolates and other 42 publically available genomes, a maximum likelihood phylogeny was constructed to establish the relationship between the Honduran isolates and those belonging to the International Clones (ICs). In addition, sequence type (ST) assignation was conducted by the PubMLST, and antibiotic resistance genes were identified using ResFinder. The Honduran isolates are highly diverse and contain new allele combinations under the Bartual multilocus sequence typing scheme. The most common STs were ST447/ST10 and ST758/ST156. Furthermore, none of these isolates belongs to clonal complexes related to the ICs. Antibiotic susceptibility profiles of these isolates showed that they are multidrug resistant (MDR) or extensively drug resistant (XDR). In addition, the Honduran isolates had genes involved in resistance to seven antibiotic families. For instance, several OXA alleles were found, including OXA-23 and a gene encoding the metallo-beta-lactamase NDM-1. Notably, nine of the Honduran isolates have antibiotic resistance genes to three or more antibiotic families. In summary, in this study, we unveiled an untapped source of genetic diversity of MDR and XDR isolates; notably, these isolates did not belong to the well-known ICs.

Over the past decade, unauthorized migration from Honduras to the USA has become a topic of pressing international concern and a major factor in the political and humanitarian crisis at the southern border of the USA that has been unfolding since 2014. Untangling the causes of recent Honduran migration requires attending to economic change, political instability, the impact of violence and crime, rapidly changing gender roles, among many other forces that shape migration patterns. Recently, scholars and policy-makers have analyzed the impact of drought in the so-called Dry Corridor of Central America as a major source of migration, particularly among coffee producers who have been hard hit by unprecedented heat and lack of rain in parts of Honduras.

The experience of intimate partner violence (IPV) is influenced by individual, relationship, community, and societal-level factors, including the prevalence and acceptance of societal violence in which the victim lives. These factors transcend a woman's present circumstances and personal history and the gender and power relationships within her household. This is particularly relevant in Honduras, where a high level of IPV occurs within a traditionally patriarchal society and growing societal violence and crime.

species are one of the most important causes of human infections, especially in hospitals and among immunocompromised patients. The correct and rapid etiological identification of yeast infections is important to provide adequate therapy, reduce mortality, and control outbreaks. In this study, species were identified in patients with suspected fungal infection, and phenotypic and genotypic identification methods were compared.

Melons are a diverse group of fresh, dessert fruits that includes orange flesh cantaloupe, green flesh honeydew, and mixed hybrid melons. As part of an effort to discover potential health benefits of fruit and vegetable peels that are considered to be byproducts of food processing, we determined the total phenolic content and antioxidative activities of methanolic extracts of the powdered peels of the following commercial melon (Cucumis melo) varieties sold at retail markets in California that were imported from Mexico and Honduras: nonorganic Canary, Charentias, Hani Gold, Vine ripened, and Santa Claus; and organic Ambrosia, Cantaloupe, Galia, Goddess, Ham, Honeydew, and Tuscan. The total phenolic content (in mg gallic acid equivalents/g extract) ranged from 0.
