Tropical climates provide ideal conditions for leptospires
to survive and transmission is exacerbated during high rainfall and flooding when bacteria are widely disseminated.
are detectable in the blood stream, decrease until 15 days (72) and (2) the start in the second week after the onset of symptoms, and the antibodies usually persist for several months (6).
The third examined the significance of understanding the relationship between leptospires
and their reservoir hosts of infection.
penetrate the host for lesions on the skin and mucous membranes.
are maintained in nature, in the renal tubules of certain animals.
Every serum which gave an agglutination of at least 50% of the leptospires
(as compared with the control antigen) was considered positive.
Leptospirosis is a bacterial infection caused by leptospires
Detection of pathogenic leptospires
by real-time quantitative PCR.
Expression and comparative analysis of genes encoding outer membrane proteins LipL21, LipL32 and OmpL1 in epidemic leptospires
Many aspects of leptospirosis epidemiology remain unknown because only limited information exists regarding leptospiral population genetics and the role of environmental factors, including environmental persistence of leptospires
, in disease occurrence.
Growth of leptospires
were checked Dark field microscope for a period of seven weeks.
The pathogenic leptospires
are divided into more than 250 different serovars and most common serovars affecting dogs include canicola, icterohaemorrhagiae, pomona, bratislava, grippotyphosa and australis (Koteeswaran, 2006).
