Effects of Sheep and Mouse Urine on the Growth Pattern of Leishmania major Promastigotes

BioMed Research International, Volume 2013, Issue 1, 2013., 2013
The protozoan parasites of the genus Leishmania are the causative agents of different clinical diseases. Fetal calf serum (FCS) is the main part and the most expensive ingredient of the Leishmania culture media. Here, the efficacies of different concentrations (1%, 2.5%, 5%, and 10%) of the filtered and autoclaved sheep and mouse urine were evaluated ...

Genes for cysteine proteinases fromTrypanosoma rangeli [PDF]

FEMS Microbiology Letters, 1995
PCR amplification of genomic DNA from the American trypanosome, Trypanosoma rangeli, using as primers oligonucleotides derived from the gene of cruzipain, the major cysteine proteinase (CP) from Trypanosoma cruzi, allowed the production of a probe which was used to obtain three clones encoding a CP with 70% overall identity with cruzipain.

Studies on Trypanosoma rangeli Tejera 1920. VII - Its effect on the survival of infected triatomine bugs

Memorias do Instituto Oswaldo Cruz, 1984
The pathological effects of Trypanosoma rangeli on Rhodnius prolixus and R. robustus, and the relation of mortality to infection, were studied under laboratory conditions. Frequent observations revealed that when the first instar nymphs of R.

Successional and native forests predict the occurrence and infection status of Chagas disease vectors in Panama

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Findings here show that successional forest predicts greater kissing bug infestation risk in palm trees, whereas native forest predicts lower kissing bug occurrence but greater infection with T. cruzi. These insights can guide land use planning towards vegetation management practices that help minimize T. cruzi transmission risks for rural communities.

First Report of Trypanosoma sp. in Spectacled Caiman (Caiman crocodilus): Morphological and Phylogenetic Relationships

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
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.

Trypanosoma rangeli expresses a β-galactofuranosyl transferase

Experimental Parasitology, 2012
Glycoconjugates play essential roles in cell recognition, infectivity and survival of protozoan parasites within their insect vectors and mammalian hosts. β-galactofuranose is a component of several glycoconjugates in many organisms, including a variety of trypanosomatids, but is absent in mammalian and African trypanosomes.

Verificação de flagelados semelhantes ao Trypanosoma rangeli Tejera, em Rhodnius prolixus alimentados em caso de doença de Chagas na Venezuela: considerações sobre a natureza deste protozoário

Memorias do Instituto Oswaldo Cruz, 1943
1) - Por inoculação do sangue de um caso agúdo de moléstia de Chagas de Zaraza, Guárico, Venezuela, em cobaia (12-11-1940), obteve-se um Schizotrypanum com caractéres morfológicos distintos dos das amostras humanas comuns do Schizotrypanum cruzi; seu ...

A Simple and Efficient Stereoselective Synthesis of a 2,3‐Difluorosialic Acid‐Based Influenza Virus Neuraminidase Inhibitor

Chemistry – A European Journal, Volume 31, Issue 16, March 17, 2025.
A new simple approach for the exquisitely stereo‐controlled introduction of the C‐3 equatorial fluorine on neuraminic acid derivatives by incorporation of steric bulk at C‐4. Through this size‐controlled method, we have elaborated a novel synthetic route that exclusively produces the potent anti‐influenza drug candidate; 2,3‐difluoro‐zanamivir analogue

Trypanosoma cruzi: Seroprevalence Detection in Suburban Population of Santiago de Querétaro (Mexico)

The Scientific World Journal, Volume 2012, Issue 1, 2012., 2012
Objectives. To evaluate the potential of iron‐oxide dismutase excreted (SODeCRU) by T. cruzi as the antigen fraction in the serodiagnosis of Chagas disease and compile new epidemiological data on the seroprevalence of this disease in the suburban population of the city of Santiago de Querétaro (Mexico). Design and Methods.
