Two outer membrane lipoproteins from Histophilus somni are immunogenic in rabbits and sheep and induce protection against bacterial challenge in mice.

Histophilus somni is an economically important pathogen of cattle and other ruminants and is considered one of the key components of the bovine respiratory disease (BRD) complex, the leading cause of economic loss in the livestock industry. BRD is a multifactorial syndrome, in which a triad of agents, including bacteria, viruses, and predisposing factors or "stressors," combines to induce disease. Although vaccines against H.

LKTA and PlpE small fragments fusion protein protect against Mannheimia haemolytica challenge.

Bovine respiratory disease (BRD) complex is a major cause of economic losses for the cattle backgrounding and feedlot industries. Mannheimia haemolytica is considered the most important pathogen associated with this disease. Vaccines against M.

Genotypification of bovine group A rotavirus in México.

Bovine scours, frequently provoked by rotavirus infection, causes significant economic losses. Nevertheless, no information exists about the bovine rotavirus genotypes present in Mexico. This information is necessary for designing efficient vaccines.
