Telomeric localization of the modified DNA base J in the genome of the protozoan parasite Leishmania [PDF]

Nucleic Acids Research, 2007
Base J or beta-d-glucosylhydroxymethyluracil is a DNA modification replacing a fraction of thymine in the nuclear DNA of kinetoplastid parasites and of Euglena. J is located in the telomeric sequences of Trypanosoma brucei and in other simple repeat DNA sequences.

Characterisation of tabanid flies (Diptera: Tabanidae) in South Africa and Zambia and detection of protozoan parasites they are harbouring [PDF]

, 2017
Tabanids are haematophagous flies feeding on livestock and wildlife. In the absence of information on the relationship of tabanid flies and protozoan parasites in South Africa and Zambia, the current study was aimed at characterizing tabanid flies ...

Unexpected Diversity and Differential Success of DNA Transposons in Four Species of Entamoeba Protozoans [PDF]

Molecular Biology and Evolution, 2005
We report the first comprehensive analysis of transposable element content in the compact genomes (approximately 20 Mb) of four species of Entamoeba unicellular protozoans for which draft sequences are now available. Entamoeba histolytica and Entamoeba dispar, two human parasites, have many retrotransposons, but few DNA transposons.

DNA break site at fragile subtelomeres determines probability and mechanism of antigenic variation in African trypanosomes. [PDF]

, 2013
Antigenic variation in African trypanosomes requires monoallelic transcription and switching of variant surface glycoprotein (VSG) genes. The transcribed VSG, always flanked by '70 bp'-repeats and telomeric-repeats, is either replaced through DNA double ...

A combination DNA vaccine encoding nucleoside hydrolase 36 and glycoproteine 63 protects female but not male hamsters against Leishmania mexicana

Parasite, 2009
Leishmaniasis is a group of diseases caused by protozoan parasites of the Leishmania genus. Previous studies have shown that a DNA vaccine encoding Leishmania donovani antigen nucleoside hydrolase 36 and L. mexicana glycoprotein 63 is protective in mice.

A nuclear family A DNA polymerase from Entamoeba histolytica bypasses thymine glycol. [PDF]

PLoS Neglected Tropical Diseases, 2010
BACKGROUND: Eukaryotic family A DNA polymerases are involved in mitochondrial DNA replication or translesion DNA synthesis. Here, we present evidence that the sole family A DNA polymerase from the parasite protozoan E.

Overview of DNA Repair in Trypanosoma cruzi, Trypanosoma brucei, and Leishmania major

Journal of Nucleic Acids, 2010
A wide variety of DNA lesions arise due to environmental agents, normal cellular metabolism, or intrinsic weaknesses in the chemical bonds of DNA. Diverse cellular mechanisms have evolved to maintain genome stability, including mechanisms to repair ...

New methods for the diagnosis of Babesia bigemina infection

Memorias do Instituto Oswaldo Cruz, 1992
Accurate diagnosis of Babesia bigemina infection, an economically important tick-transmitted protozoan parasite of cattle, is essential in the management of disease control and in epidemiological studies.
