Parasites with zoonotic potential found in commercially important fish in Tamaulipas, Northeastern Mexico.

Human population is exposed to numerous parasitic ichthyozoonoses. Although Tamaulipas state (northeastern Mexico) is well known for its fishing and aquaculture industry, there are few reports of this type of zoonosis. Therefore, it is imperative to investigate whether the parasites that affect these fish may represent a zoonotic risk for the inhabitants of the area.

Density-dependent condition of juvenile penaeid shrimps in seagrass-dominated aquatic vegetation beds located at different distance from a tidal inlet.

Seagrasses are critical habitats for the recruitment and growth of juvenile penaeid shrimps within estuaries and coastal lagoons. The location of a seagrass bed within the lagoon can determine the value of a particular bed for shrimp populations. Consequently, differences in the abundance of shrimp can be found in seagrasses depending on their location.

Effect of Propolis, a Honeybee Product, Against a Parasite (Ligictaluridus floridanus) from Catfish (Ictalurus punctatus) Gills.

Purpose: The aim of this study was to evaluate the in vitro and in vivo efficacy of propolis against Ligictaluridus floridanus on Ictalurus punctatus gills.

Methods: This study used an ethanol extract of propolis at a concentration of 300 mg mL, with a total polyphenol concentration of 2.77 mg mL as determined by chromatography.

Confined toluene within InOF-1: CO capture enhancement.

The toluene adsorption properties of InOF-1 are studied along with the confinement of small amounts of this non-polar molecule revealing a 1.38-fold increase in CO capture, from 5.26 wt% under anhydrous conditions to 7.

The influence of host ecology and biogeography on the helminth species richness of freshwater fishes in Mexico.

Freshwater fish helminths, the most well known Mexican vertebrate parasites, include approximately 260 species (platyhelminthes, acanthocephalans, nematodes, and hirudineans). The distribution patterns of adult helminth diversity (throughout parasite and host groups and hydrological regions) are described and the effects of host traits and environmental and geographical factors on diversity are evaluated. Adult helminths include 160 species, parasitizing 149 fish species of 23 families distributed in 21 regions.
