Infectivity of Aflagellar Epimastigotes of Trypanosoma caninum in the DH82 Cell Line and Mouse Peritoneal Macrophages

Journal of Parasitology Research, Volume 2025, Issue 1, 2025.
Background:Trypanosoma caninum presents aflagellar and flagellar epimastigote, trypomastigote, and spheromastigote forms in axenic cultures. Attempts to utilize trypomastigote forms of T. caninum to develop in vitro and in vivo infection models have failed. To investigate the infection potential of aflagellar epimastigotes, T.

Associations Between Developmental Stability, Canalization, and Phenotypic Plasticity in Response to Heterogeneous Experience

Ecology and Evolution, Volume 14, Issue 10, October 2024.
Decreased canalization may promote plastic responses in traits before or during the induction of plasticity, whereas canalization may reflect phenotypic convergence after plastic responses. ABSTRACT The processes of developmental stability, canalization, and phenotypic plasticity have ecological and evolutionary significance, and been studied ...

Estudo sobre a utilização de Rhodnius neglectus para xenodiagnósticos realizados em marsupiais (Didelphis) The utilization of Rhodnius neglectus in xenodiagnosis: a study performed on opossums

Revista de Saúde Pública, 1976
Em marsupiais (Didelphis), portadores de infecção natural pelo T. cruzi, procurou-se levar a efeito xenodiagnósticos com o emprego de ninfas de Rhodnius neglectus e de Triatoma infestans e através do exame periódico de lotes formados por cinco insetos ...

Trypanosomes and gut microbiota interactions in triatomine bugs and tsetse flies: A vectorial perspective

Medical and Veterinary Entomology, Volume 38, Issue 3, Page 253-268, September 2024.
Trypanosoma sp. presence modulates or has zero effect on gut microbiota composition. Microbiota presence modulates or has zero effect on Trypanosoma sp. growth. Vector biology of triatomine bugs and tsetse flies influences their gut microbiota composition.

Chromosomal location of heterochromatin and 45S rDNA sites in four South American triatomines (Heteroptera: Reduviidae)

Comparative Cytogenetics, 2010
The Triatominae are distributed in Brazilian regions and are the vector of Chagas disease. This group is also characterized by lower karyotype variability, occurrence of holokinetic chromosomes and inverted meiosis of the sex chromosomes.

Biology, diversity and strategies for the monitoring and control of triatomines - Chagas disease vectors

Memorias do Instituto Oswaldo Cruz, 2009
Despite the relevant achievements in the control of the main Chagas disease vectors Triatoma infestans and Rhodnius prolixus, several factors still promote the risk of infection. The disease is a real threat to the poor rural regions of several countries

Insights from tissue-specific transcriptome sequencing analysis of Triatoma infestans

Memorias do Instituto Oswaldo Cruz
Triatoma infestans is an insect of subfamily Triatominae (Hemiptera: Reduviidae) and an important vector of Trypanosoma cruzi, the etiologic agent of human Chagas disease. In this work we reported a transcriptome assembly and annotation of T.

How sexual reproduction affects the population biology of Phytophthora infestans [PDF]

, 2012
Phytophthora infestans is a rapidly evolving and highly adaptable pathogen. It is the cause of late blight, one of the most devastating diseases in potato production. Depending on whether both mating types are present or not, P.
