Host conservation through their parasites: molecular surveillance of vector-borne microorganisms in bats using ectoparasitic bat flies

Parasite, 2020
Most vertebrates host a wide variety of haematophagous parasites, which may play an important role in the transmission of vector-borne microorganisms to hosts.

Examining marginal sequence similarities between bacterial type III secretion system and Trypanosoma cruzi surface proteins: Horizontal gene transfer or convergent evolution? [PDF]

arXiv, 2012
The cell invasion mechanism of Trypanosoma cruzi has similarities with some intracellular bacterial taxa especially regarding calcium mobilization. This mechanism is not observed in other trypanosomatids, suggesting that the molecules involved in this type of cell invasion were a product of (1) acquired by horizontal gene transfer; (2) secondary loss ...

Increased CD8dim and Decreased CD8bright T Cells as Immunological Signature for Multibacilary Leprosy Patients

Immunology, EarlyView.
Leprosy, a chronic infectious disease caused by Mycobacterium leprae, manifests in a spectrum of clinical forms and severity. This study investigated the percentage of CD8+ T cells and their subpopulations (CD8bright and CD8dim T cells) in leprosy patients stratified by clinical forms, bacterial load, and age.

SUMOylation inTrypanosoma brucei

PeerJ, 2013
Small ubiquitin like modifier (SUMO) proteins are involved in many processes in eukaryotes. We here show that Trypanosoma brucei SUMO (Tb927.5.3210) modifies many proteins. The levels of SUMOylation were unaffected by temperature changes but were increased by severe oxidative stress.

Converting Blastocrithidia Nonstop, a Trypanosomatid With Non‐Canonical Genetic Code, Into a Genetically‐Tractable Model

Molecular Microbiology, EarlyView.
Blastocrithidia represents a very small group of species, in which all 3 stop codons are reassigned to encode amino acids with only one of them serving a dual role of a sense and a stop codon simultaneously. Here we demonstrated for the first time that B. nonstop can be genetically modified.

Linajes de Trypanosoma cruzi en pacientes con enfermedad de Chagas y coinfección por VIH [PDF]

, 2009
Introducción. Las poblaciones naturales de T. cruzi han sido clasificadas en seis linajes filogenéticos o unidades de tipificación discreta: T. cruzi I, IIa, IIb, IIc, IId y IIe, que pueden jugar un rol en el tropismo tisular y patogénesis de la ...

Perspectives on the Trypanosoma cruzi-host cell receptor interaction [PDF]

, 2009
Chagas disease is caused by the parasite Trypanosoma cruzi. The critical initial event is the interaction of the trypomastigote form of the parasite with host receptors. This review highlights recent observations concerning these interactions.

Potential geographic displacement of Chagas disease vectors under climate change

Medical and Veterinary Entomology, EarlyView.
As a result of modelling the potential distribution of 55 triatomine species in the Neotropical region, with climate change projected for up to 2050, we found no significant changes. With climate change projected for up to 2080 in the Neotropical region, we see a significant potential for the migration of 55 species of triatomines towards the Amazon ...

Hydroxyurea-induced synchronisation of bloodstream stage Trypanosoma brucei [PDF]

, 2009
Synchronisation of the <i>Trypanosoma brucei</i> cell cycle proved elusive for many years. A recent report demonstrated that synchronisation of procyclic form cells was possible following treatment with hydroxyurea.

Identification of a new fish trypanosome from the large yellow croaker (Larimichthys crocea) and description of its impact on host pathology, blood biochemical parameters and immune responses

Parasite
The aim of this study was to clarify the taxonomic identification of a hemoflagellate and assess the effect of trypanosome infection on Larimichthys crocea. Giemsa staining showed the presence of three morphotypes of trypomastigotes. The trypanosomes had
