This paper deals with the epizootiology and the natural transmitters of Leucocytozoonosis in transmitters cpizootiology of Leucocytozoonosis in chickens and its in Fujion Province. Thin blood films from 1526 chickens were examined for Lencocytozoonosis infection. The incidence-rate varied from 12.55% to 94.67% with an average of 62.25%. .From the endemic farms in Loon-Hai district, it was found that 61.1% to 61.8% of the 768 infected chickens with serious illness or ending in fatality belong to 2-4 and 5-7 month age-groups.Blood examinations were taken in 10 acutely infected chickens. It Was clearly indicated that blood feature of the infected chickens were lower than those of healthy birds. The pathological effects were anemia, splenomegaly, liver hypertrophy and degeneration in 18 cases of necropsy.The first appearance of gametocytes in the peripheral blood of the infected chickens were found in 10th to 14th days after experimental injection. The parasitemia reached their peaks varing from 19th to 29th days after injection. They usually remained at a higher teevel in the blood circulation for a long period (30-130 days).As shown, by the examination of 9 naturally infected chickens, there was a diurnal fluctuation of gametocyte-numbers in the peripheral blood. The diurnal periodicity was characterized by the peak densities during daylight hours.There were three species of Simulium of which only Simulium sp. 1 showed to be a natural vector for Leucocytozoon sabrazesi 118 of 336 examined were found to be naturally infected with ookinetes, oocysts and sporozoids. Among 1-18 infected flies, 8 of them were being sporozoid infections. There were 17 chickens ( 4 months old) being experimentally injected with saline of Simulium sp. 1, 8 of them (47.06%) were proved to be infected with Leucocytozoon sabrazesi 11-14 days after injection.The diurnal fluctuation in Simulium numbers were studied in a semi-quantitative survey. It was found that the maximum number was in the early morning (5-6 a.m.), and a small peak was found at evening (7-7.15 p.m.). The lowest number tended to occur in the afternoon (1-4 p.m.), Survey on the seasonal incidence of Simulinm number was carried out during 1974-1975. The great majortiy of Simulium population invelving larvae, pupae and adults wese found from May to July and the peak appeared in June. The numbers fell down quickly in August, but higher number counts appeared again from September to March of next year.

For experimental research cn malaria, it is necessary to have a fairly high and relatively stable infection rate of the mosquite vectors with malaria parasite. Many factors are known to exert influence on the sporogeny of P.yoelii, so far, we have made observations only on(1) the influence of splenectomy on the course of infection of mice (Kuming strain) with P.ycelii; (2) that of P-amincbenzoic acid on its sporogonic stages; and(3) the rhyrnic periodicity of infectivity of the gametocytes of the parasite to the mosquitoes The results obtained are reported as follows:(1)It was found that in the splenectomized animals, their parasttemia reached a peak level 6 days after inoculation (3×107-4.5×107 parasitized cells inoculated) and remained at a high level through to the end. The animals began to die from day 8 onwards and finally a total of 7 out of 10 test animals died of the infection within 20 days. However, in the intact animals infected with the same parasites the parasitemia gradually peaked in 8-12 days after inoculation and then dropped rapidly. All of them became latent by day 22 without death at all(2)Two to four days after blood inoculation intact mice were found most infective to the anophline mosquitoes with a gland infection rate of about 40%. The mosquitoes feeding on the splenectomized infected mice during the same period gave rise to, however, a higher gland infection rate than the former. The later the time want on, the more statistically significat the difference in the rate between the two groups of mosquitoes became(P<0.001). while the rate of the latter was still as high as 38.5±7.4% on day 10 after inoculation, that of the formerdropped down to zero.(3)In comparison with the control (without addition of PABA) more oocysts of the parasites were developed in the mosquito vectors when they were fed on the PABA of various concentrations (0.5%, 0.05%, 0.005%) added to the glucose solution. The 0.05% concentration was found most suitable for development of theoocysts.(4)The peak level of the infection rate of the vector, when fed on the mice with blood induced infection, varied with the time of blood inoculation. For instance, it occured at about midnight (20:00-24:00) when inoculated at 12 O'clock; conversely, it did at about noon (08:00-12:00) when inoculated at 24:00. But no such a change as mentioned above has been noted in the sporozoite-induced infections of mice with the parasite, at least in the early generations of schizogonic cycle.

Fine structures of Leucocytozoon sabrazesi gametocytes from peripheral blood of infected chickens were studied via electron microscopy. All gametocytes examined were situated intracelluary in lymphocytes and monocytes. It was found that some of them appeared to be round in shape and others elongated ovoid.Both macro-and micro-gametocytes were surrounded by three layers of clearly marked membranes; The thickness of the outermost membrane is 19.78nm; the middle membrane 18.99nm; and the intermost membrane 25.59nm. They all contain nuclei, nucleoli, ribosomes, lipid inclusions round osmiophillic bodies, axonems. mitochondria with microtubular cristae and host cell nuclei. Macroga-metccytes are easily distinguished from microgametocytes by dark staining appearance. The nuclei in microgametocytes are large and diffuse. The structures of mature elongate gametocytes of Leucocytozoon sabrazesi appeared to be remarkly similar to the Leucocytozoon simondi.The only difference being that in the macrogametocytes of the former there are many lipid inclusions in the cytoplasm.
