La prevalencia de infecciones por Toxoplasma gondii en el ser humano es de 5-90% según la zona geográfica; en Costa Rica por ejemplo, la seroprevalencia es de un 58%, por lo que es importante comprender algunos procesos inmunológicos, propios en estas ...

Trypanosoma musculi infections in complement-deficient mice
Abstract Strains of mice (CFW, C57B1/10Sn, B10.D2/nSn, and B10.D2/oSn) were infected with Trypanosoma musculi ( Trypanosoma duttoni ). The complement-deficient B10.D2/oSn mice showed typical parasitemias similar to those presented by the strains possessing hemolytic complement activity. Peak parasitemias occurred 12 days postinoculation.

The immunosuppression caused by species of the gender Trypanosoma has been widely documented. The influence over experimental infections with Toxoplasma gondii is evident when using Trypanosoma lewisi, a natural parasite of white rats. We decided to test the effect of Trypanosoma musculi from mice, an organism with very similar biological ...

Unclear host taxonomy hinders parasite studies: An up-to-date checklist of the protozoan and metazoan parasites of Phoxinus minnows (Teleostei: Leuciscidae). [PDF]
Abstract Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas ...

Lysozyme Activity in the Plasma of Rodents Infected with their Homologous Trypanosomes
Background: In this study the concentration of lysozyme in blood plasma of Microtus agrestis, Clethrinomys glareolus, Apodemus sylvaticus, BK rats and outbred white mice before and after infection with culture forms of Trypanosoma microti, T, evotomys ...

Enhanced Trypanosoma musculi infections in mice with concomitant malaria
A PHASE of immunodepression is characteristic of experimental malaria infections and, in mice, immune responses to antigens as diverse as sheep red blood cells1, tetanus toxoid2, oncogenic viruses3 and Toxoplasma gondii4 are diminished. From immunological and epidemiological viewpoints it is important to know what happens when animals are infected with

Response of inbred mice to infection with a new isolate ofTrypanosoma musculi [PDF]
SummaryA new isolate ofTrypanosoma musculihas been derived from organisms recovered fromMus spretuscaptured in Lisbon, Portugal. The time-course and profiles of infection with this isolate in inbred mice have been compared with those obtained with the existing Partinico II isolate. Infections with the Portuguese isolate are less intense, and controlled

Trypanosoma musculi infection in B-cell-deficient mice. [PDF]
The course of infection with Trypanosoma musculi was assessed in mice deprived of B-lymphocytes by administration, from birth, of rabbit antiserum to mouse immunoglobulin M (IgM). Initial control of parasitemia leading to the first crisis and establishment of the plateau phase was unaffected by lack of B-lymphocyte function, although multiplicative ...

Lipopolysaccharide hyperreactivity of animals infected with Trypanosoma lewisi or Trypanosoma musculi. [PDF]
Rats and mice infected with Trypanosoma lewisi and Trypanosoma musculi, respectively, showed hyperreactivity to lipopolysaccharide (LPS) from gram-negative bacteria. Fatal shock could be precipitated with a dose of LPS 100 to 1,000 times less in infected compared with noninfected animals.
