Plants offer a unique combination of advantages for the production of valuable recombinant proteins in a relatively short time. For instance, a variety of diagnostic tests have been developed that use recombinant antigens expressed in plants. The envelope glycoprotein gp51 encoded by Bovine...

Vaccination has proved to be an efficient strategy to deal with viral infections in both human and animal species. However, protection of cattle against viral infections is still a major concern in veterinary science. During the last two decades, the development of efficient plant-based expression...

Phylogeography data are of paramount importance in studying the molecular epidemiology dynamics of foot-and-mouth disease virus (FMDV). In this study, epithelial samples and oesophageal-pharyngeal fluids were collected from 361 convalescent animals (cattle and buffaloes) in the field throughout...

AIMS: To study the occurrence and spatial distribution of Shiga toxin-producing Escherichia coli (STEC) O157 in calves less than 1-week-old (bobby calves) born on dairy farms in the North Island of New Zealand, and to determine the association of concentration of IgG in serum, carcass weight,...

This replaces the B.Vet.C. of 1953 and its 1959 Supplement, and comes into force in March 1966. Monographs on 57 drugs, 18 biological products and 42 formulations have been added, among them ami-carbalide (Diampron), amprolium hydrochloride, cyacetazide (cynacethydrazide), diaveridine (Dar-visul),...

Foot and mouth disease virus. Type A. was rendered avirulent by 28 passages in day old chicks or 12 in embryonated eggs. These strains, were non-pathogenic, had good antigenicity and did not spread by contact. In field trials with the chick embryo strain immunity lasted at least eight months....

Bovine VIBRIOSIS was studied to assess the value of vaccination and to record the events leading to infertility. V. fetus cultures were introduced into the vagina a year before heifers came to first service to determine whether immunity will develop from such an exposure. A killed culture was used...

I. The examination of lesions in lymph nodes from pigs for Mycobacterium tuiberculosis and the typing of the strains was continued. Glands were divided into five groups. Group 1, "Mottled Glands", contained no distinct lesions but had fine white striations. Group 2 nodes had a large encapsulated...

A survey of the incidence of MASTITIS in cows dispelled the belief that mastitis due to Str. agalactiae has become negligible since the introduction of penicillin. Of milk samples from 6, 185 cows 16% were infected with Sir. agalactiae. There was a much lower incidence of Str. agalactiae in regions ...
