leishmaniasis is an important and common zoonotic disease with a great impact on public health. in the present study, a total of 195 companion cats of different ages were examined for serum antibody detection against leishmania infantum by immunochromatography assay. the cats were selected from those referring to veterinary hospital of ahvaz university, south west of iran from may 2009 to march...

General Considerations The most common etiologic agents of VL are 3 species of the L. donovani complex: Leishmania donovani donovani and Leishmania donovani infantum in the Indian subcontinent, Africa, China, the Mediterranean littoral, and the Middle East; and Leishmania donovani chagasi in South America. (Hereafter, organisms will be identified only by genus and species; eg, L. donovani for L...

The diagnosis of visceral leishmaniasis remains difficult in rural areas where the disease is endemic, and serologic methods still need assessment, as they are not very sensitive for the detection of asymptomatic infectious dogs. Here we present data on the development of enzyme-linked immunosorbent assay (ELISA)-based methods for the detection of antibodies against recombinant leishmanial anti...

In this study, a genotypification of Leishmania was performed using polimerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and sequencing techniques to identify species of Leishmania parasites in phlebotomine sand flies and dogs naturally infected. Between January-February of 2009, CDC light traps were used to collect insect samples from 13 capture sites in the municipali...

BACKGROUND Lutzomyia longipalpis is the vector of Leishmania infantum in the New World, and its saliva inhibits classical and alternative human complement system pathways. This inhibition is important in protecting the insect´s midgut from damage by the complement. L. longipalpis is a promiscuous blood feeder and must be protected against its host's complement. The objective of this study was t...

Canine leishmaniasis is a chronic parasitic disease transmitted by small bloodsucking insects. Clinically, affected patients present with progressive wasting, slight or marked reduction in appetite, lymphadenomegaly, splenomegaly, and cutaneous lesions (e.g., dry desquamation [dry seborrhea], ulcers, nodules). A correct diagnosis is based on specific serologic and molecular tests and nonspecifi...

Leishmaniosis caused by Leishmania infantum is an endemic zoonosis present in the Mediterranean area. Canidae (dog and fox) constitute the main reservoir hosts for the parasite, whilst wild rodents or the cat can be carriers of the protozoan and are considered as secondary potential reservoirs. This paper describes a case of disseminated feline leishmaniosis with cutaneous (ulcerative), viscera...

CASE SUMMARY This is the first clinical report of feline viscerocutaneous leishmaniosis caused by Leishmania infantum genotype E associated with an invasive squamous cell carcinoma (SCC) in a domestic cat from Portugal. Initially, the cat presented a single cutaneous lesion in the right nostril. A fine-needle aspiration was performed and Leishmania amastigotes were observed without the presence...

BACKGROUND Although many studies had been conducted on various aspects of canine visceral leishmaniasis (CVL) in domestic dogs in the endemic areas of Iran, investigations on CVL in wild canines are rare. METHODS This is a cross-sectional study was conducted from December 2012 to 2013 in northeast of Iran where human VL is endemic. Wild canines were trapped around the areas where human VL cas...

Despite the broad distribution of leishmaniasis among Iranians and animals across the country, little is known about the genetic characteristics of the causative agents. Applying both HSP70 PCR-RFLP and sequence analyses, this study aimed to evaluate the genetic diversity and phylogenetic relationships among Leishmania spp. isolated from Iranian endemic foci and available reference strains. A t...
