Leptospires may also be detected by histopathological examination in tissues using silver or immunohistochemical stains Levettbut the infecting serovar cannot be determined Bolin Leptospirosis in the Phillipines: However, there is a lack of large studies providing evidence for this threshold and the use of paired serum samples collected at different stages of the infection is prefered.
The incubation period of canine leptospirosis is about 5 to 15 days Van de Maele et al Hartmann K, C Greene. Some animals suffer severe clinical signs of leptospirosis when they are infected with serovars for which they are not adapted and they are called “incidental hosts”. The degree of transmission of the infection depends on climate, population density and contact rates between incidental and maintenance hosts Levett Cornell Vet 48, However, the relationship between infecting serovar and clinical disease requires further research Goldstein et al Frecuency and type of renal lesions in dogs naturally infected with Leptospira species.

Venkataraman KS, Nedunchelliyan S. Table 4 shows the results of some cross-sectional studies of Leptospira infection in felines worldwide.
Prevalence of Leptospira infection and frequently reported serovars in dogs in published cross-sectional studies carried lfptospirosis in Chile. In natural infections, IgM titres leptodpirosis within 1 week of infection and peak at 14 days after infection, whereas IgG titres are not present until 2 to 3 weeks after infection and peak at 1 month post infection Langston and Heuter Some serovars have worldwide distribution, while others have a more limited geographical spread Miller et al Leptospirosis in the family dog: Greene C, R Schultz.

This change has been cahina to widespread use of bivalent Leptospira vacines introduced in the s, as well as the increased contact between dogs and wildlife reservoirs in expanding suburban environments Stokes et al Int J Vet Res 5, In the primary reservoir hosts, kidney colonization occurs because the bacterium persist in the kidney tubular epithelial cells Sessions and Greene a.
Epidemiology of an outbreak of leptospirosis in man and dog.
Leptosppirosis prevent the disease in pets and their owners, simple preventive measures can be applied focusing on reducing the chances of infection, including vaccination leptospirsois dogs, good hygiene and to avoid the exposure of dogs and cats to infected animals and reservoir hosts.
In humans, worldwide incidences of leptospirosis has been estimated in 0. A specific disease syndrome in the cat is difficult to recognise or occurs most infrequently Agunloye and Nash Treatment of other dogs in the households that may have been coincidentally exposed to leptospires in the environment is recommended with antibiotics like doxycycline, and ideally with monitoring of acute and convalescent phase leptospiral antibody titres Sykes et al Clin Vaccine Immunol 14, Acha P, Szyfres B eds.
The MAT panel for canine leptospirosis should include serovars known to be circulating in the local dog population Leptospurosis et al Some maintenance or primary reservoirs and incidental hosts of common serovars of Leptospira interrogans that infect dogs, cats and other animals have been mentioned by Greene et al and are summarised in table 1.

These hosts can shed the bacterium in the urine for months intermittently or throughout their life, leading to the direct or indirect infection of other leptospirrosis or humans Van de Maele et al Canine leptospirosis infections clinical signs and outcome with different suspected Leptospira serogrups 42 cases. Iran J Vet Res 5, Higgins R, P Cayouette.
Nevertheless, all recovered patients should be monitored closely for at least 6 to 12 months after therapy, for development of complications associated with chronic renal failure Sessions and Greene b.
Laboratory testing is essential for the diagnosis, however, it is complicated due to the need to discriminate between Leptospira infection in animals with clinical disease from leptospiral specific antibody responses in maintenance hosts, or in animals with subclinical infection.

Further research is needed to better understand the transmission dynamics and how these are influenced by climatic events, environmental factors, animal reservoirs, demographic, social and human trends Lau et al The intermediate species are distinct from lleptospirosis and non-pathogenic strains according to their rRNA 16S sequence, and their virulence has not been demonstrated experimentally.
Outbreaks often increase after periods of flooding or increased rainfall. The disease can be presented as peracute, acute, subacute or chronic Langton and Heuter Serologic study of feline leptospirosis in Theran, Iran.
However most of the commercially available and in-house tests for leptospirosis have no validation of their diagnostic performance and some present variable results depending of the country or geographic region that hampers their selection as tests of choice Picardeau et al Penicillin and its derivates are the antibiotics of choice for the treatment of leptospiremia in dogs:
