Arginase activity in pathogenic and non-pathogenic species of Leishmania parasites. [PDF]

PLoS Neglected Tropical Diseases, 2017
Proliferation of Leishmania (L.) parasites depends on polyamine availability, which can be generated by the L-arginine catabolism and the enzymatic activity of arginase (ARG) of the parasites and of the mammalian hosts.

Ecological determinants of leishmaniasis vector, Lutzomyia spp.: A scoping review

Medical and Veterinary Entomology, Volume 38, Issue 4, Page 393-406, December 2024.
Lutzomyia spp. survival is impacted by climatic, habitat and geodemographic factors. Lutzomyia spp. have demonstrated a wide range of temperature tolerance, ranging from 11 to 30°C. There is limited research on this topic, posing a significant challenge for future studies. Abstract Leishmania spp. are zoonotic parasites transmitted by phlebotomine sand

A cross‐sectional study on phlebotomine sand flies in relation to disease transmission in the Republic of Kosovo

Medical and Veterinary Entomology, Volume 38, Issue 4, Page 573-585, December 2024.
We provide the currently known sand fly distribution and species diversity in Kosovo, including a COI barcode inventory and distribution maps. Phlebotomus neglectus and Ph. perfiliewi were identified to be the predominant species and environmental analyses depicted two geographical groups of sand flies in Kosovo, with notable differences between the ...

A Global Map of Suitability for Coastal Vibrio cholerae Under Current and Future Climate Conditions [PDF]

, 2015
Vibrio cholerae is a globally distributed water-borne pathogen that causes severe diarrheal disease and mortality, with current outbreaks as part of the seventh pandemic. Further understanding of the role of environmental factors in potential pathogen distribution and corresponding V. cholerae disease transmission over time and space is urgently needed

Investigation of Viral, Bacterial and Parasitic Zoonotic Diseases in Rodents in Turkey

Veterinary Medicine and Science, Volume 10, Issue 6, November 2024.
Rodents are reservoir hosts for zoonotic pathogens. In this study, the presence of viral lymphocytic choriomeningitis and hantavirus infections, bacterial tularaemia and leptospirosis, and parasitic leishmaniasis and toxoplasmosis were investigated in 498 rodents collected in Erzurum province, Turkey.

The complexities of blood‐feeding patterns in mosquitoes and sandflies and the burden of disease: A minireview

Veterinary Medicine and Science, Volume 10, Issue 5, September 2024.
Mosquitoes and phlebotomine sandflies are infectious disease vectors through hematophagy. The development of hematophagy likely provided an evolutionary advantage, offering a rich nutrient source for reproduction. These insects exhibit diverse blood‐feeding patterns, from invertebrates to various vertebrates. Multiple sensory cues to guide host‐seeking

Automated identification of flagella from videomicroscopy via the medial axis transform [PDF]

, 2018
Ubiquitous in eukaryotic organisms, the flagellum is a well-studied organelle that is well-known to be responsible for motility in a variety of organisms. Commonly necessitated in their study is the capability to image and subsequently track the movement of one or more flagella using videomicroscopy, requiring digital isolation and location of the ...

Detection, molecular typing and phylogenetic analysis of Leishmania isolated from cases of leishmaniasis among Syrian refugees in Lebanon

Parasite Epidemiology and Control, 2016
Leishmania is a parasitic protozoan with more than two-dozen species causing the disease leishmaniasis. It is transmitted to humans through the bite of an infected female phlebotomine sand-fly vector.
