| detection of new babesia microti-like parasites in a rhesus monkey (macaca mulatta) with a suppressed plasmodium cynomolgi infection. | a new type of piroplasm, phylogenetically closest to babesia microti-like parasites previously detected in eurasian red squirrels (sciurus vulgaris orientis), was identified in a rhesus monkey (macaca mulatta) imported from china. after challenge with plasmodium cynomolgi m strain blood-stage parasites, the rhesus monkey repeatedly showed markedly reduced levels of plasmodium parasitemia when compared with animals not infected with this organism. | 2008 | 18385363 |
| malignant melanoma of the eyelid in a red squirrel (sciurus vulgaris orientis). | a 6-year-old male red squirrel (sciurus vulgaris orientis) developed bilateral tumors of upper and lower eyelids. the tumors in the left lid recurred despite surgical removal. necropsy revealed metastasis to the lung. the neoplastic cells were epithelioid and highly pleomorphic, and only a few cells contained melanin granules. occasionally melanoma cells were immunoreactive for s100, neuron-specific enolase and vimentin, and a small number of cells for cytokeratin. ultrastructurally, the presenc ... | 2002 | 11999447 |
| babesia microti-like parasites detected in eurasian red squirrels (sciurus vulgaris orientis) in hokkaido, japan. | six eurasian red squirrels (sciurus vulgaris orientis), victims of road traffic found during 2002 and 2004 near the noppro forest park in ebetsu, hokkaido, japan, were examined for the presence of babesia parasites. three of the six squirrels exhibited positive signals by nested pcrs targeting both the 18s rrna and beta-tubulin genes. three squirrels proved to be infected with a b. microti-like parasite as evidenced by sequencing the amplified dnas and by the morphology of the intraerythrocytic ... | 2006 | 16891774 |
