“…Another advantage is the specific immunization provoked also by C. ovis adjuvant against Corynebacterium ovis infection in sheep, cattle and buffa loes, taking into account that immunity to C. ovis is mainly cellular (11,8), and that there is no reliable serological test until now for its diagnosis (17).…”

Corynebacterium ovis has a clear immunopotentiating effect when used as an adjuvant with several antigens including egg albumin, Salmonella typhimurium and foot and mouth disease virus, inoculated into guinea pigs. The optimal dose was found to be 400 mg of C. ovis mixed with antigen. However, a dose of 300 mg of C. ovis when mixed with incomplete Freund's adjuvant was enough to stimulate a sustained potent immune response which was superior to that obtained with the complete Freund's adjuvant. Immunopotentiation is a topic in immunology that is attracting increasing interest. In this field, oil adjuvants have proved their superiority and Freund et al. (10) have shown that the addition of some bacteria, such as mycobacte ria, to such oil adjuvants improves their immunopotentiating effect. Current studies carried out in our laboratory on crystal violet treated C. ovis have clearly shown its capacity as a non-specific immune stimulant, capable of raising the resistance of sheep to artificial infection with potential pathogens, in a manner comparable with that produced by BCG (5, 6). It was decided to test the formalin-killed C. ovis for its immunopotentiat ing ability when used as an adjuvant with inert antigens and killed microbial vaccines. MATERIALS AND METHODS Animals. Guinea pigs : 630 healthy albino adult guinea pigs, weighing approxim ately 400-500 grams, were used in this study. The animals were put in equal * Under-Secretary of State for Veterinary Affairs, Egypt.

“…Occurrence of Leptospira infection in goats has been reported from many countries in South America (Ahl and others 1992, Ciceroni and others 1997, Lilenbaum and others 2007), Africa (Shigidi 1974, Moch 1975) and Asia (Pargaonker and Ramakrishna 1963, Kharole and Rao 1968, Sawhney 1968). Several epidemiological studies have been conducted in Europe and most of them come from Mediterranean Basin countries such as Greece (Burriel and others 2003), Portugal (Rocha 1998), Spain (Leon‐Vizcaino and others 1987) and Italy (Ciceroni and others 2000).…”

Leptospiral antibodies in the breeding goat population of Poland

In 2007, a survey was conducted on the prevalence of antibodies to 19 Leptospira serovars in goats in Poland . Sera were collected from adult females of all 49 breeding goat herds in Poland by applying simple random sampling. In total, 736 sera were tested by the microscopic agglutination test. A herd was considered seropositive if at least one goat with a titre of 100 or more was detected. Herd-level seroprevalence of Leptospira was 89.8 per cent and individual-level seroprevalence varied from less than 1.0 to 85.0 per cent among the herds. Antibodies to Leptospira serovars Zanoni, Bratislava, Autumnalis, Australis and Javanica were most frequently detected. Although 40.3 per cent of seropositive goats had high antibody titres (≥ 400), suggesting recent infection, no relationship with abortions or other clinical manifestation of leptospirosis in goats was detected.

“…In Africa, titers to the Pyrogenes serogroup have been detected in cattle from Uganda (4), in goats and sheep in the Sudan (26), and in humans in Nigeria (9). Strains of serogroup Pyrogenes have been isolated in Kenya and Nigeria.…”

The Royal Tropical Institute, 1105 AZ Amsterdam, The Netherlands3Five strains of the genus Leptuspiru belonging to serogroup Pyrogenes were isolated from cattle slaughtered in Zimbabwe and subjected to cross-agglutinin absorption and restriction fragment length polymorphism analysis. One strain, SBF 2, represents a new genetic strain of serovar kwule, while another strain, SBF 49, is a new genetic strain closely related to serovar nigeriu. Three strains belong to a new serovar for which the name mombe with reference strain SBF 20 is proposed. Restriction fragment length polymorphism analysis indicated that each of these three strains represents a different restriction polymorphism pattern group.
