Two new endemic species of Lygaeinae from Baja California, Mexico (Hemiptera: Heteroptera: Lygaeidae) .

Na+/K+-ATPase resistance and cardenolide sequestration: basal adaptations to host plant toxins in the milkweed bugs (Hemiptera: Lygaeidae: Lygaeinae).

Despite sequestration of toxins being a common coevolutionary response to plant defence in phytophagous insects, the macroevolution of the traits involved is largely unaddressed. Using a phylogenetic approach comprising species from four continents, we analysed the ability to sequester toxic cardenolides in the hemipteran subfamily Lygaeinae, which is widely associated with cardenolide-producin...

Immunopathological evaluation of recombinant mycobacterial antigen Hsp65 expressed in Lactococcus lactis as a novel vaccine candidate

Bovine tuberculosis (TBB) is a zoonotic disease distributed worldwide and is of great importance for public health and the livestock industry. Several experimental vaccines against this disease have been evaluated in recent years, yielding varying results. An example is the Bacillus Calmette-Guérin (BCG) vaccine, which has been used extensively in humans and tested in cattle showing mixed resul...

Induction of Lactation in Holstein Cows Using Progesterone Injections or Progesterone Vaginal Inserts

The aim of this study was to evaluate the effect of replacing progesterone injections by progesterone vaginal inserts on productive and reproductive parameters of lactating cows with reproductive problems after prolonged periods of heat stress. Fifteen Holstein cows were randomly assigned to one of three treatments: 1) treated with two progesterone vaginal inserts (P4-INS); 2) treated with prog...

Helminth parasites of some freshwater fishes from Baja California Sur, Mexico

Nine freshwater fish species were sampled from 13 bodies of water in Baja California Sur state, on the Baja California peninsula, Mexico. Twenty-four helminth parasite species of 19 genera and from 13 families were recorded. All are new records for the region, but have been recorded previously in Mexico. No endemic helminth species were identified. Most helminths were larval forms of generalist...

Identification of the nymphal stages of two European seed bugs, L. equestris and L. simulans (Hemiptera: Heteroptera: Lygaeidae), using DNA barcodes.
