This research aims at studying sero infection of leptospira interrogans in farms of Sarab. For this purpose, 200 serum samples were randomly collected. Six kinds of alive leptospira antigens, ballum, canicola, grippotyphosa, icterohaemorrhagia, hardjo,Pomona were isolated using MAT test. The results obtained from this test demonstrated that 23% of animals sera were serologically positive for di...

Leptospirosis is a neglected emerging infectious disease with high burden in Africa. Major reservoirs of leptospirosis are rodents and other small mammals. Studies of leptospirosis in bats and the extent to which they contribute to its transmission to humans and domestic animals in Tanzania are lacking. The objective of this study was to determine the prevalence of leptospirosis and local Lepto...

Leptospirosis, a disease with protean manifestations, is caused by Leptospira species. Early and reliable identification of Leptospira serovars remains to be a challenge due to diversity at serovar level. The potential of polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) was assessed for detection of sequence variation in pathogenic specific 631 bp fragment of 16S r...

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...

Canine leptospirosis is a zoonosis caused by bacteria belonging to the genus Leptospira. Dogs are one of animal species involved in cycle preservation and transmission urban areas. Serological testing for presence specific antibodies against Leptospira spp. dogs was continuously performed between 2010 2020 city Belgrade. At request owners themselves, other veterinary laboratories or laboratory ...

Leptospirosis is a worldwide zoonosis caused by Leptospira interrogans which include all pathogenic strains of the Genus Leptospira. The serological classification of the members of Leptospira interrogans distinguishes more than 200 serovars which have traditionally been grouped into serogroups according to their antigenic relation [16]. After natural infection with Leptospira, the spectrum of ...

The Leptospira interrogans vaccines currently available are serovar specific and require regular booster immunizations to maintain protection of the host. In addition, a hamster challenge batch potency test is necessary to evaluate these vaccines prior to market release, requiring the use of a large number of animals, which is ethically and financially undesirable. Our previous work showed that...
