“…It was significant to observe that unlike the last study in 1979 on canine leptospirosis conducted in the country where the predominant serovars detected serologically and by culture were canicola, icterohaemorrhagiae and hebdomadis (Everard et al, 1979), in the current study of apparently healthy and suspected cases of leptospirosis, no sample was positive for serovar canicola while some dogs were infected by serovar icterohaemorrhagiae. The absence of serovar canicola in canine leptospirosis has also been reported in some countries (Dikenson and Love, 1993;Weekes et al, 1997). Serovars canicola and icterohaemorrhagiae have been reported to be the predominant serovars responsible for canine leptospirosis leading most commercially available vaccines to include both serovars (Rentko et al, 1992;Faine, 1994).…”

A sero-epidemiological study on canine leptospirosis was conducted in house, stray, farm and hunting dogs, as well as in suspect cases of clinical canine leptospirosis. Serum samples were collected from apparently healthy (vaccinated and nonvaccinated), house dogs. A questionnaire was administered to the owners to elicit information on risk factors for leptospirosis. The microscopic agglutination test was used to screen for leptospirosis using 17 international serovars. Reciprocal titres of between 100 and <800 were considered as evidence of past exposure while reciprocal titres of 800 or greater were classified as suggestive of acute/current infection. Of a total of 419 serum samples tested, 61 (14.6%) were seropositive for Leptospira agglutinins, 23 (5.5%) had mixed infections and 16 (3.8%) had current infection. Amongst 50 suspected cases of clinical leptospirosis, 24 (48.0%) were seropositive and only 13 (26.0%) had current infection compared with 10 (6.3%) and three (1.9%) of 160 apparently healthy house dogs respectively. The difference was statistically significant (P < 0.05; v 2 ). Twelve (25.5%) of 47 hunting dogs, 10 (20.4%) of 49 farm dogs and five (4.4%) of 113 stray dogs were seropositive (P < 0.05; v 2 ). Overall, a total of nine serovars were detected with serovars mankarso, icterohaemorrhagiae RGA, autumnalis and copenhageni being involved in 29 (47.5%), 20 (32.8%), 25 (41.0%) and 10 (16.4%) respectively in 61 seropositive dogs (P < 0.05; v 2 ). Serovar mankarso was most predominant in seropositive apparently healthy dogs, 37.8% (14/37), suspected clinical cases of leptospirosis, 62.5% (15/24) compared with serovar icterohaemorrhagiae with a frequency of 21.6% (8/37) and 50.0% (12/24), the difference being statistically significant (P < 0.05; v 2 ). Although all vaccines used for prevention of canine leptospirosis in the country contain serovars canicola and icterohaemorrhagiae, serovar mankarso was mostly associated with infection and disease and may be a good candidate for inclusion in the vaccine used locally. The public health risk posed to owners of dogs infected with Leptospira cannot be over-emphasized considering the zoonotic nature of the disease.

Seroprevalence of Cat Leptospirosis in Belgrade (Serbia)

With its epizootiological characteristics, the territory of the municipality of Belgrade city is a potentially important locality for the maintenance and spreading of a number of serovars of Leptospira interrogans. In order to evaluate the epizootiological situation as far as animal leptospirosis in the Belgrade region is concerned, from January 2012 until June 2013 the prevalence of cat leptospirosis has been evaluated. The standard microagglutination test (MAT) was used to determine animals sero positive to different serovars that belong to L. interrogans sensu lato complex. The antigens used were: Icterohaemorrhagiae, Grippotyphosa, Pomona, Canicola, Bratislava, Batavie, Sejroe, Pyrogenes, Australis and Autumnalis. Out of the total number of tested animals, there were 43 (26.7%) positive to one, two or three serovar(s). Out of a total of 43 positive sera 20 (46.5%) samples were positive to more than one leptospira serovar.

between potential risk factors and both seropositive horses to the predominant serovar Bratislava and to Leptospira spp were statistically evaluated using univariable analysis and multivariable logistic regression models.Adult horses admitted to each equine hospital and horses seen on ambulatory service for various purposes were included in the study. Severely-ill, chronically infected, and horses with underlying immunosuppressive conditions were excluded from sampling, to control for potential bias.A total of 663 horse sera were collected and tested against a panel of 24 leptospiral serovars using the microscopic agglutination test. The most predominant serovars in Gauteng were The apparent prevalence to one or more serovars of Leptospira spp at a serum dilution of 1:100 in Gauteng, KwaZulu-Natal and Western Cape Provinces was 49%; 37% and 32% respectively. The true prevalence was calculated for each province taking into account the clustering effect during the sampling and was found to be between 24-74% in Gauteng; 26-39% in the Western Cape and 20-54% in KwaZulu-Natal.iv Nooitgedacht (South African horse breed) horses were found to be at greater risk of being seropositive to both serovar Bratislava (OR=5.08) and Leptospira spp (OR=6.3). Similarly, horses residing on properties with forestry in the vicinity were found to be at greater risk of being seropositive to both serovar Bratislava (OR=9.3) and Leptospira spp (OR=5.2). This study has shown that a high proportion of horses in South Africa are exposed to a wide range of serovars, inferring a complex epidemiology. It also describes for the first time new serovars of Leptospira in South African horses that have not previously been reported.v
