hepatozoon griseisciuri infection in gray squirrels of the southeastern united states. | blood films and selected tissue sections from 270 gray squirrels (sciurus carolinensis) from 18 sites in 11 southeastern states were examined for hepatozoan griseisciuri. this parasite was found in 110 (41%) squirrels from 17 of the 18 sites. data suggested transmission of the parasite apparently occurs throughout the year and increases from spring to late summer. the infection was more prevalent in subadults and adults than in juveniles. schizogonic stages were found only in the lungs, suggesti ... | 1976 | 815571 |
tissue "cysts" of hepatozoon griseisciuri in the grey squirrel, sciurus carolinensis: the significance of these cysts in species of hepatozoon. | the lungs of a grey squirrel infected with hepatozoon griseisciuri contained, in addition to typical haemogregarine schizonts, small cysts, each of which contained a single cystozoite. the presence of these cysts, which resemble those recorded in hepatozoon species in reptiles, suggests that they may be a common feature in all hepatozoon species and that these parasites may be transmitted by predation as well as by ingestion of infected arthropod vectors. | 1990 | 2319428 |

hepatozoon griseisciuri in grey squirrels (sciurus carolinensis): changes of blood leucocyte numbers resulting from infection. | numbers of leucocytes in squirrels with gametocytes of hepatozoon in their blood (infected) were compared with animals without gametocytes (uninfected). typical values for leucocytes/mm3 blood in uninfected squirrels were: leucocytes 5.7 x 10(3), granulocytes 3.4 x 10(3), lymphocytes 2.0 x 10(3) and monocytes 0.3 x 10(3) cells. infection caused an increase in monocytes, lymphocytes and granulocytes, and there was a significant positive association between parasitaemia level and numbers of both t ... | 2003 | 12954012 |
