Promastigote infectivity inLeishmania infantum [PDF]

Parasitology Research, 1991
Different clones and subpopulations of clones of Leishmania infantum were analyzed for their infective potential in vitro. Infectivity for macrophage-like cells (P388D1) and the response to a challenge with normal human serum enabled a clear differentiation between infective and non/low-infective populations. The results were confirmed by determination

Susceptibility of Cebus nigrivittatus to Leishmania infantum

The Journal of Parasitology, 1986
is associated with nausea, vomiting, and deafness with tinnitus. Such afflicted individuals cannot walk and have to lie down in bed without turning over. Our observations on the motility of dolphins that were pushed back into the water or captured in a pool indicated a disturbance of equilibrium. Odontoceti suffering from acute octavus neuropathy might

A seroepidemiological survey on Leishmania infantum infection

European Journal of Epidemiology, 1991
Findings from a seroepidemiological survey of Leishmania infantum (LI) infection are presented. Among residents in the province of Rome, 2.7% (4.4% in the city of Rome and 1% in the suburbs) of 374 adults were positive for specific LI antibodies in indirect haemoagglutination studies.

Molecular tracking of infections by Leishmania infantum

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2001
Leishmania infantum is a major opportunistic parasite in patients with acquired immune deficiency syndrome and is very variable in these subjects. Isoenzyme characterization is not able to explain this variability, since half of the stocks isolated from patients co-infected with human immunodeficiency virus and Leishmania belong to zymodeme MON-1 ...

Amplification of the H locus in Leishmania infantum

Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 1994
We have selected for a Leishmania infantum cell line resistant to high levels of methotrexate (MTX). The resulting cells were 1233-fold more resistant than wild-type and contained amplified H-region circles. Homologous genes to the antifolate resistant ltdh gene and to the P-glycoprotein ltpgpA gene of Leishmania tarentolae were observed to be ...

Thymoquinone Effect on Leishmania tropica/infantum and Leishmania-Infected Macrophages

Acta Parasitologica, 2023
Leishmania is a parasitic protozoan that tries to enter and amplify within macrophages. Macrophage cells are also immune defense cells that phagocyte many microbes like bacteria, fungi, as well as parasites like Leishmania spp. However, they are unable to kill this parasite that resides in the phagosomes of contaminated macrophages and multiplies in ...

Leishmaniosis (Leishmania infantum infection) in dogs

Revue Scientifique et Technique de l'OIE, 2015
The authors present an overview of canine leishmaniosis due to Leishmania infantum. This protozoan is transmitted by sandflies and the disease is frequently characterised by chronic evolution. Cutaneous and visceral clinical signs appear as the infection progresses.

Detection of Leishmania (Leishmania) amazonensis and Leishmania (Leishmania) infantum chagasi in Brazilian bats

Veterinary Parasitology, 2010
Although bats are one of the most abundant mammals in the new world and are present in virtually all ecosystems, including urban and peri-urban environments, few studies have investigated the role of these animals in the epidemiological chain of leishmaniosis.

Genetic diversity and phylogenetic relationships between Leishmania infantum from dogs, humans and wildlife in south‐east Spain

Zoonoses and Public Health, 2019
Leishmania infantum causes human and canine leishmaniosis. The parasite, transmitted by phlebotomine sand flies, infects species other than dogs and people, including wildlife, although their role as reservoirs of infection remains unknown for most ...

Feline leishmaniosis due to Leishmania infantum in Italy

Veterinary Parasitology, 2002
A case of leishmaniosis in domestic cats (Felis catus domesticus) is described. The subject showed a nodular lesion on the eyelid. The diagnosis was achieved by serological, parasitological, and light and electron microscopic investigations. By molecular techniques the aetiological agent was identified as belonging to Leishmania infantum, the species ...
