Isolation of Machupo Virus from Wild Rodent Calomys callosus
American Journal of Tropical Medicine and Hygiene, 1966Summary 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.

Immune Tolerance in Calomys callosus infected with Machupo Virus
Nature, 1969MACHUPO 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 ...

AbstractThe genus Calomys includes several species that have very similar external morphologies, which often leads to confusing field identification and has resulted in conflictive taxonomic histories. One of its clades involves large‐sized body forms, known as the Calomys callosus complex.

Morphological and quantitative study of ganglionated plexus of Calomys callosus trachea
Autonomic Neuroscience: Basic and Clinical, 2008Calomys 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.

Structural evaluation of the effects of chronic ethanol ingestion on the testis of Calomys callosus
Tissue and Cell, 2009Chronic exposure to ethanol may results in pathophysiologic changes in cellular function. The present work was designed to investigate the morphology of testis submitted to experimental ethanol ingestion. Experimental animals were divided into two groups.

Trophoblastic invasion of the uterine epithelium in Calomys callosus (Rodentia, cricetidae)
Journal of Morphology, 1994AbstractImplantation 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,

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.
