The effects of the exposure of the bacterium, Leptospira interrogans serovar canicola to a constant magnetic field with magnetic flux density from a permanent ferrite magnet=140+/-5 mT were studied. Changes in Leptospira cells after their exposure to the field were determined on the basis of changes in their growth behavior and agglutination immunoreactivity with a homologous antiserum using da...

INTRODUCTION The aim of the study was to compare haemoglobin and red cell counts between patients known to be infected with a range of leptospiral serovars. METHODS The study retrospectively compared the haemoglobin and red cell count results from the first blood samples taken from 207 patients at presentation to a Queensland Health hospital. RESULTS Significant differences were observed in...

L eptospirosis is a worldwide zoonotic disease caused by infection with the spirochete bacterium Leptospira inteTragons.L. interrogans is further divided on the basis of antigenic relatedness into serogroupsand serovars. Approximately 200 different serovars of L. interrogans have been identified, and within a geographic region, certain serovars are prevalent and becomeadapted to a particular ma...

The prevalence of Leptospira interrogans serovars in dairy cattle was determined by analyzing 464 serum samples from cows on 15 properties in Garanhuns municipal district, Pernambuco State, Brazil. A microscopic seroagglutination test including 12 serovars of Leptospira interrogans as antigens was used. Samples with titres 100 were considered positive. Two hundred and twenty-one (47.63%) of the...

Changes in lipid fractions were evaluated in young guinea pigs when infected with 1 ml of 7 day old live cultures of leptospira interrogans serovars australis, canicola and icterohaemorrhagiae. Statistically significant elevation in triglycerides, very low density lipoprotein and phospholipid and a significant reduction in high density lipoprotein (HDL) in all the groups was observed. Cholester...

Aim: To study the seroprevalence of leptospirosis in dogs in Kerala and to identify the most prevalent serovar. Materials and Methods: A total of 205 sera collected from dogs were screened for the presence of antibodies against leptospirosis by Microscopic Agglutination Test (MAT). Results: A seroprevalence rate of 71.12 per cent was observed. Leptospira interrogans serovar Autumnalis was found...
