Fish are often infected with different blood protozoa of the genera Babesiosoma, Trypanosoma, and Hemogrigarina. These parasites match which infect mammals. A total 120 samples from five fish species (Barbus grypus, Barbus sharpyi, Liza abu, Carasobarbus luteus, Aspius vorax) were collected Khazar River in Ninevah Governorate, Iraq at weekly intervals during period April 2022 to October for det...

Trypanosoma brucei rhodesiense was named after Rhodesia which, in turn, the British imperialist and white supremacist Cecil Rhodes. In light of Black Lives Matter movement contemporary consciousness postcolonial legacy, it seems opportune to reconsider subspecies name. Pros cons renaming T. b. are discussed.

Most African trypanosomes, including the veterinary species Trypanosoma brucei brucei and T. congolense are susceptible to lysis by human serum. A recent study by Alsford et al. [PLoS Pathogens (2014) 10, e1004130] has identified a T. b. brucei lysosomal cathepsin with an inhibitory effect on human serum's trypanolytic action.

In this study we analyze and compare the trends in codon usage in five representative species of kinetoplastid protozoans (Crithidia fasciculata, Leishmania donovani, L. major, Trypanosoma cruzi and T. brucei), with the purpose of investigating the processes underlying these trends. A principal component analysis shows that the G+C content at the third codon position represents the main source ...

In Crocodylidae family three trypanosomes species were described, T. grayi in African crocodilian and T. cecili and Trypanosoma sp. in Caimans species from Brazil. T. grayi was transmitted by tsetse flies and the vector of Brazilian caimans trypanosomes is unknown. We characterized first Brazilian trypanosome isolated in spectacled caiman (Caiman crocodilus) from Mato Grosso State in Brazil. Mo...

N-Ribohydrolases, including the inosine-adenosine-guanosine-preferring (IAG) nucleoside hydrolase, have been proposed to be involved in the nucleoside salvage pathway of protozoan parasites and may constitute rational therapeutic targets for the treatment of these diseases. Reported is the complete sequence of the Trypanosoma brucei brucei iagnh gene, which encodes IAG-nucleoside hydrolase. The...

Members of the subfamily Triatominae, family Reduviidae, comprise a large number of insect species of which some are vectors of Trypanosoma cruzi, the causative agent of Chagas' disease. This article outlines research on the process of transformation and the dynamics of developmental stages of Trypanosoma cruzi in the triatomine insect hosts. Special attention is given to the interactions of pa...

To investigate possible cardiac manifestations of Chagas disease, we tested 97 Latinx patients with nonischemic cardiomyopathy in Houston, Texas, USA, for Trypanosoma cruzi infection. We noted a high prevalence underdiagnosed infection and discrepant results clinical diagnostic assays. the United States would benefit from laboratory screening T.

A Canadian man came to the hospital with history of daily fever in the afternoon, for five days, ranging from 38.5oC to 39oC, headache, muscle pain and asthenia. He is a photographer enthusiastic about wild life and had been to Zimbabwe for 14 days, where he filmed groups of lions and animals of the African megafauna. Upon examination, he presented a hyperemic skin lesion in the posterior regio...
