Prevalence and Antimicrobial Resistance of in Different Raw Food from Reynosa, Tamaulipas, Mexico.

() is an opportunistic foodborne pathogen that causes listeriosis in humans and animals, reaching up to 30% case mortality. There are only a few reports in Mexico about the strains found in various foods. The aim of this study was to determine the prevalence of , serogroups, virulence genes, and antimicrobial resistance in different foods from Reynosa, Tamaulipas, Mexico.

Genetic structure and historical and contemporary gene flow of in the Gulf of Mexico slope: a microsatellite-based analysis.

Background: from the river basins of the Gulf of Mexico slope are small freshwater fish that usually live in large groups in different freshwater environments. The group is considered successful due to its high capacity for dispersal and adaptation to different habitats, and the species present high morphological variability throughout their distribution in Mexico. This has produced the most extreme morphotype of the group; the hypogeous or troglobite, which has no eyes or coloration, and is probably the cause of taxonomic uncertainty in the recognition of species across the entire range.

Microsatellite loci obtained by next generation sequencing on the sablefish (Anoplopoma fimbria).

Eleven microsatellite loci were developed and characterized for the sablefish, Anoplopoma fimbria. The markers were identified from sequences obtained by next generation sequencing. Thirty samples from Aleutians Islands were genotyped.

Role of oceanography in shaping the genetic structure in the North Pacific hake Merluccius productus.

Determining the relative influence of biotic and abiotic factors on genetic connectivity among populations remains a major challenge in evolutionary biology and in the management and conservation of species. North Pacific hake (Merluccius productus) inhabits upwelling regions in the California Current ecosystem from the Gulf of California to the Gulf of Alaska. In this study, we examined mitochondrial DNA (mtDNA) and microsatellite variation to estimate levels of genetic differentiation of M.

Isolation and characterization of 14 tetranucleotide microsatellite loci for the cannonball jellyfish (Stomolophus sp.) by next generation sequencing.

The Cannonball jellyfish (Stomolophus sp.) is a species of jellyfish with high relevance in artisanal fishing. Studies of their populations do not extend beyond the morphological descriptions knowing that presents a great morphological variability.

The complete mitogenome of the live-bearing fish (Bean, 1887) (Actinopterygii: Goodeidae).

The live-bearing fish is representative of the viviparous Goodeinae subfamily (Goodeidae) from central Mexico. The mitogenome of the consist of 37 genes in 16,462 bp. Comparing with , the most related of the mitogenomes included, an identity of 91.

Genetic Structure of Pacific Trout at the Extreme Southern End of Their Native Range.

Salmonid fishes are cold water piscivores with a native distribution spanning nearly the entire temperate and subarctic northern hemisphere. Trout in the genus Oncorhynchus are the most widespread salmonid fishes and are among the most important fish species in the world, due to their extensive use in aquaculture and valuable fisheries. Trout that inhabit northwestern Mexico are the southernmost native salmonid populations in the world, and the least studied in North America.
