This study aimed to determine whether asymptomatic horses naturally infected with Theileria equi retain infected erythrocytes in the spleen and whether the presence of the hemoparasite in this organ is associated with parasitemia. We collected samples from 25 adult horses without clinical signs of any disease. From each animal, we collected whole blood samples from the jugular vein and a splenic puncture blood sample. All samples were submited to blood cell counts and detection of Theileria or Babesia. DNA extraction and PCR were performed in all samples for identification of piroplasm infection (T. equi and B. caballi). From the 25 horses evaluated for piroplasm detection by PCR, seven horses (28%) were positive in jugular vein blood but negative in splenic blood samples, five horses (20%) were positive in splenic blood samples but negative in jugular vein blood samples, and 13 horses (52%) were positive in both jugular vein and splenic blood samples. The hematological evaluation revealed anemia in 13 of 25 (52%) infected horses, lymphopenia in five (20%), neutrophilia in two (8%), neutropenia in one (4%), and thrombocytopenia in one (4%) infected horse. The present study demonstrated that several (20%) of the asymptomatic piroplasm carrier horses did not show parasitemia, but show infected erythrocytes in the spleen.

Parameters of virulence and the course of infection were compared in mice infected with Toxoplasma gondii strains P-Cz (mice virulent), 38 (cyst-forming, highly pathogenic) and HIF (cyst-forming, avirulent). Mice, that succumbed to infection with cystforming strain 38 had lesions in the spleen (days 7-14 p.i.), liver (days 7-14 p.i.), lungs (days 9-21 p.i.), heart (days 14-21 p i.), and brain (days 21-35 p.i.). In contrast, the animals which succumbed to strain P-Cz had practically unaffected hearts and brains. There were no fundamental differences in the temporal sequence of histopathological changes in infections with virulent and both cyst-forming strains. Depending on the virulence of each strain the infections differed markedly in the degree of organ damage, duration of parasitemia, numbers of cysts in the brain, as well as in mortality and body weight loss. The differences in post mortem findings are not due to different organ affinity, but to the virulence-dependent time of death. All P-Cz infected mice die in the early stage of infection, before their hearts and brains can be seriously damaged.

Haemoproteus osea sp. nov. is described from the blood of Nectarinia osea, sunbird species, endemic to Israel and the Red Sea zone of Arabia. Infection was found only in one out of 44 birds, in Eilat, at the north end of Gulf of Aqaba; level of parasitaemia was 0.07%. Young gametocytes adhere alongside the nucleus. The gametocytes extend alongside the erythrocyte nucleus, filling the entire space to the erythrocyte envelope and only slightly impose over the tip of the erythrocyte nucleus. Mean nuclear displacement ratio is 0.75. H. osea differs from H. sequeirae Tendeiro, 1947 in having the microgametocyte cytoplasm blue staining, similarly to the macrogametocyte, rather than reddish white, and also in causing less evident displacement of the erythrocyte nucleus.
