In vivo binding of the Cry11Bb toxin of Bacillus thuringiensis subsp. medellin to the midgut of mosquito larvae (Diptera: Culicidae).

Bacillus thuringiensis subsp. medellin produces numerous proteins among which 94 kDa known as Cry11Bb, has mosquitocidal activity. The mode of action of the Cry11 proteins has been described as similar to those of the Cry1 toxins, nevertheless, the mechanism of action is still not clear.

In situ detection of antigenic glycoproteins in Taenia solium metacestodes.

Taenia solium has a complex life cycle. Its cysticercus can lodge in the brain, causing neurocysticercosis (NCC), and the adult tapeworm's survival in the intestine results in taeniasis. In this study, the in situ detection of previously described glycoprotein antigens used for serological diagnosis of NCC and the detection of other glycoconjugates was explored in cysticerci and the surrounding porcine tissue to understand their potential role in pathogenesis.

The inflammatory cell infiltrates in porcine cysticercosis: immunohistochemical analysis during various stages of infection.

Taenia solium metacestodes cause cysticercosis in both humans and pigs. In the former host species, the central nervous system involvement (neurocysticercosis (NCC)) may range from asymptomatic to life-threatening, but little is known about the corresponding variation in tissue response due to the difficulty in obtaining parasite-infected brain biopsies. The use of pigs as animal models for cysticercosis is ideal because the histological description of the animal's response around the parasites resembles the one recorded in human specimens.
