Trophoblastic invasion of the uterine epithelium in Calomys callosus (Rodentia, cricetidae)

Journal of Morphology, 1994
AbstractImplantation sites in the uterus of the cricetid rodent Calomys callosus were examined by light and electron microscopy at several points during day 4 of pregnancy to determine the changes occurring in the trophoblast and epithelial cells during the early blastocyst‐endometrial relationship, particularly the epithelial removal phase. By morning,

Influence sexual dimorphism on the persistence of blood parasites in infected Calomys callosus

Research in Veterinary Science, 2008
Gender has long been known to be a contributory factor in the incidence and progression of disorders associated with immune system disregulation. The aims of this experiment were to verify the influences of sexual dimorphism on the persistence of blood parasites out of the acute phase of infection.

Nitric oxide involvement in experimental Trypanosoma cruzi infection in Calomys callosus and Swiss mice

Parasitology Research, 1997
Nitric oxide (NO) production by peritoneal macrophages was evaluated in Calomys callosus and Swiss mice during the course of infection with two strains of Trypanosoma cruzi. In C. callosus, no NO production was detected throughout the period of observation in animals infected with either parasite strain, except for a very low amount measured on day 40 ...

Trypanosoma cruzi: Effects of social stress in Calomys callosus a natural reservoir of infection

Experimental Parasitology, 2008
Social environment can represent a major source of stress affecting cortisol and/or corticosterone levels, thereby altering the immune response. We have investigated the effects of social isolation on the development of Trypanosoma cruzi infection in female Calomys callosus, a natural reservoir of this protozoan parasite. Animals were divided in groups

Mast cells in the eyes of Calomys callosus (Rodentia: Cricetidae) infected by Toxoplasma gondii

Parasitology Research, 2002
The mast cell is a powerful effector cell for the innate immune system, acting through the secretion of several distinct mediators. Few studies have demonstrated the relationship between mast cells and toxoplasmosis. In this study, mast cells were investigated in two experimental Toxoplasma infections using Calomys callosus (Rodentia: Cricetidae) as ...

Azithromycin Reduces Ocular Infection During Congenital Transmission of Toxoplasmosis in the Calomys callosus Model

Journal of Parasitology, 2009
Toxoplasma gondii is a widely distributed obligatory intracellular parasite that causes severe disease to the fetus when transmitted during pregnancy. Drugs used to avoid congenital transmission have shown side effects, and their efficacy is controversial.

Normal hematologic values of various age groups of Calomys callosus (Rodentia Cricetidae).

Laboratory animal science, 1996
Hematologic values for Calomys callosus, a wild rodent, were established. Males and females from a colony raised in Animal Housing of the Institute of Tropical Medicine of São Paulo were examined individually. For the red blood cell series, the number of erythrocytes, hemoglobin concentration, hematocrit, and platelet and reticulocyte numbers were ...
