MODULATION OF PARASITEMIA AND ANTIBODY-RESPONSE TO TRYPANOSOMA-CRUZI BY CYCLOPHOSPHAMIDE IN CALOMYS-CALLOSUS (RODENTIA, CRICETIDAE)

open access: yes, 1992
Calomys callosus a wild rodent, previously described as harboring Trypanosoma cruzi, has a low susceptibility to infection by this protozoan.Experiments were designed to evaluate the contribution of the immune response to the resistance to T.

Immune Tolerance in Calomys callosus infected with Machupo Virus

Nature, 1969
MACHUPO virus, the aetiological agent of Bolivian haemorrhagic fever, is an ether-sensitive RNA virus immunologically classified as a member of the Tacaribe group of “arboviruses”1–3. Repeated isolation of this virus from the cricetine rodent Calomys callosus4, the demonstration of chronic virus infection with persistent viruria in this animal5, and ...

Isolation of Machupo Virus from Wild Rodent Calomys callosus

The American Journal of Tropical Medicine and Hygiene, 1966
Summary Nine virus strains were recovered from a small group of tissues from the wild rodent Calomys callosus captured in the area of San Joaquin, Bolivia, in 1963. Each virus was successfully reisolated and shown to be serologically related to Machupo virus, the etiologic agent of Bolivian Hemorrhagic Fever.

Morphological and quantitative study of ganglionated plexus of Calomys callosus trachea

Autonomic Neuroscience, 2008
Calomys callosus is a wild, native forest rodent found in South America. In Brazil, this species has been reported to harbour the parasitic protozoan Trypanosoma cruzi. The ganglionated plexus of this species was studied using whole-mount preparations of trachea that were stained using histological and histochemical methods.

Influence of Trypanosoma cruzi Chronic Infection in the Depletion of Esophageal Neurons in Calomys callosus

Digestive Diseases and Sciences, 2006
The extent of neuronal loss was studied in this work, in aged female Calomys callosus infected with the MORC-1 strain of Trypanosoma cruzi. Fifteen months after infection, one group of animals was immunosuppressed with cyclophosphamide (CY). Sections of the distal esophagus were collected and stained with cresyl violet.

Evaluation of the ethanol intake on the Calomys callosus seminal vesicle structure

Micron, 2008
The effects of chronic alcohol ingestion on the structure of the glandular epithelium of the seminal vesicle of the rodent Calomys callosus were analyzed in 24 adult animals aged 3 months divided into three experimental groups. The control group received a solid diet and tap water, the alcoholic group received the same solid diet and ethanol P.A ...

Chronic ethanol ingestion on the uterine horn of Calomys callosus

2023
The present work was carried out to evaluate the possible effects of chronic alcohol intake on the histology and ultrastructure of the endometrial lining epithelium of the uterine horn of Calomys callosus. 20 adult female rodents, Calomys callosus, three months old, were used. These animals were divided equally into 2 experimental groups called control
