Leishmania infantum is the main species causing leishmaniosis in dogs and cats, as well as visceral and cutaneous forms of leishmaniosis in humans.

L infantum is most likely transmissible from cats to sand flies, because sand flies have been shown to feed on cats and to be infected after feeding on naturally infected cats. infection in cats, combined with the absence of clinical signs, might indicate that these animals are healthy carriers of these parasites. Cats exposed to L. infantum are able to mount a cell-mediated immune response that does not parallel antibody production. Your doctor will be looking for evidence of such diseases as lupus, cancer, and distemper, among other possible causes for the symptoms. This is a zoonotic infection, and the organisms residing in the lesions can be communicated to humans. are transmitted by sandflies. Of the 100 cats, 54 were seropositive for Leishmania … Recent epidemiological studies suggest that cats living in Leishmania endemic areas have similar exposition risk and prevalence data of dogs from the same area despite gen-erally being asymptomatic or subclinical [61,62]. Seropositivity was 60.0% (Ab titer > or =10) and 28.3% of animals presented Ab titers > or =40. Since there are often related lesions on the skin's surface, a skin biopsy will be in order as well. Hyperkeratosis — most prominent finding; excessive epidermal scaling with thickening, depigmentation (loss of skin color), and chapping of the muzzle and footpads, Nodules usually develop on the skin surface. This article provides an understanding of the epidemiology, life cycle and transmission of Leishmania infantum, reviews its diagnosis and treatment, and briefly discusses the current understanding of feline leishmaniosis.

The aim of the present study was to assess the prevalence of Leishmania infantum antibodies and DNA in blood samples collected in a sample of stray cats in metropolitan area of Milan in northern Italy, which is a nonendemic area … Traveling to endemic regions (usually the Mediterranean), where the cat can be exposed to sandflies -- a Leishmania host -- is the most common way of contracting the infection. Leishmaniosis (leishmaniasis) is a longterm, severe, protozoal (parasitic) disease of humans, dogs, and other animals. Recent epidemiological studies suggest that cats living in Leishmania endemic areas have similar exposition risk and prevalence data of dogs from the same area despite generally being asymptomatic or subclinical [61,62].When associated with disease, FeL may include a variety of signs, with skin or mucocutaneous lesions and lymph node enlargement being the most … In the great majority of cases, the condition occurs when the parasite Leishmania infantum is transmitted to the dog or cat, through the bite of a specific group of Phlebotomus (sandflies).

Leishmania are vector-borne protozoan parasites within the group known as the Kinetoplastids. These organisms will never be entirely eliminated, and relapse, requiring treatment, is inevitable. Leishmania-specific antibodies are prevalent in cats living in ecoregions around the Northwestern Mediterranean basin; thus, leishmaniasis must … Also see professional content regarding leishmaniosis.
