In dogs and cats, the disease is caused by different serovars and while dogs act as maintenance host for some serovars, both species are incidental host for others.
Dogs that recover from leptospirosis may have permanent renal dysfunctions that require life-long therapy.

Leptospirosos has been suggested that a MAT titre of 1: Expedido por Instituto Nacional del Derecho de Autor. There is no evidence to suggest that cats are less capable of transmitting leptospirosis than dogs, but the characteristic squatting posture that cats assume when they urinate and the fact that they cover the urine, could limit the chances of prolonged survival of the organism Everard et al Some of the Leptospira serovars found in canines, in cross-sectional surveys carried out in different countries worldwide, are listed in the table 2.
The prevalence of leptospiral antibodies in free roaming cats in Worcester County, Massachusetts. However, the relationship between infecting serovar and clinical disease requires further research Goldstein et al Semin Vet Med Surg 11, Dogs may be sentinels for human exposure to leptospires Moore et al Laboratory testing is essential for the diagnosis, however, it is complicated due to the need to discriminate between Leptospira infection leptosoirosis animals with clinical disease from leptospiral specific antibody responses in maintenance hosts, or in animals with subclinical infection.
Health Science Journal 2, Climate change, urbanisation and leptospirosis: A serological survey of leptospirosis in cats. The transmission of the Cwnina infection occurs by contact of intact mucous membranes or abraded skin with infected urine or urine-contaminated soil, water, food and also after bite-wound inoculation or leptospiosis of infected tissues Sykes et al Leptospirosis in dogs; a review with emphasis on clinical aspects.
For this reason, dog peptospirosis should be aware that their pets may not be fully protected because serovars that cause the disease may vary temporally and leptsopirosis Guerra However, the increasing epidemiological evidence that other serovars are involved in clinical infections highlights the emerging need to produce new and multivalent Leptospira vaccines Wilson et al a.
Direct identification on darkfield microscopy has been used as a rapid screening test to identify leptospires in the urine of dogs Bolin but it is no longer recommended because of its technical difficulty and low specificity.

Leptospires may also be detected by histopathological examination in tissues using silver or immunohistochemical stains Levettbut the infecting serovar cannot be determined Bolin Zavitsanou A, F Babatsikou.
Arch Med Vet 28, J Vet Intern Med 20, However, most of the infections produce no pathognomonic signs Silva and Riedemann Acute leptospirosis is characterised by fever, vomiting, dehydration, tachypnoea and shock which can occur so quickly that hepatic or renal failure do not have time to develop Van de Maele et al ; this form is known as Stuttgart disease Faine 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 Immunization protects against disease caused by the homologous or antigenically similar serovars and the antibodies produced are relatively serovar-specific Levett However, recent serological evidence, demonstrated a change in the predominant serovars implicated in canine infections, for example in USA and Canada Goldstein et al It is known that domestic dogs are important reservoirs of infection for humans because they can shed live bacteria in the urine for months with no clinical signs Batista et aland especially in urban areas dogs should be considered as an important risk factor for leptospirosis Rodriguez et al Leptospirosis is a zoonotic disease of worldwide distribution caused by spirochetes of the genus Leptospira.
Young animals could be more vulnerable to the disease as they are reported to be more seriously affected than adults Bolin Serologic study of feline leptospirosis in Theran, Iran. In this sense, human infections of leptospirosis can be acquired by veterinarians, farmers, animal caretakers, animal researchers and by people exposed to contact with pet dogs or domestic livestock during daily activities Langston and Heuter The main problem is that the presence of other bacteria, detritus or artefacts in the sample can be confused with leptospires, conducting to false positive and false negative results.
Leptospirosis has a complex epidemiology in which a variety of domestic and wild animal species are involved. Venkataraman KS, Nedunchelliyan S.
Experimental canine leptospirosis caused by Leptospira interrogans serovars pomona and bratislava. Thus, there is an urgent need to develop new diagnostic test that are especially user-friendly, as well as leptosplrosis is canian need for the rapid detection of antibodies or antigens in the acute stage of the disease Picardeau Frequency of observed serovars of Leptospira.
To prevent the disease in pets and their owners, simple preventive measures can be applied focusing on reducing the chances of infection, including vaccination in dogs, good hygiene and to avoid the exposure of dogs and cats to infected animals and reservoir hosts.
