| the erythrocytic entry- and exit-mechanism of aegyptianella pullorum carpano, 1928. | the erythrocytic entry- and exit-mechanisms of aegyptianella pullorum were investigated and characterized by scanning (sem) and transmission electron microscopy (tem) using for tem ruthenium red as a marker of the red cell plasmalemma. the scanned aegyptianella preparations produced static evidence of an endocytosis followed by an erythrocytic vesiculation as the possible mode of entrance of initial bodies into erythrocytes. the presence of ruthenium red only coating the membrane around the para ... | 1979 | 120644 |
| tick-borne diseases of domestic animals in northern nigeria. ii. research summary, 1966 to 1976. | during the first 10 years of its existence, the department of parasitology and entomology of the faculty of veterinary medicine, ahmadu bello university in zaria, nigeria, confirmed or described for the first time the occurrence of 25 different tick-borne parasites of domestic animals in the northern part of the country. most of these organisms occur as inapparent infections but may serve as complicating factors in any adverse host condition. the transmission of babesia bigemina by boophilus dec ... | 1977 | 339447 |
| [the efficacy of pleuromutilins on aegyptianella pullorum infections in chickens (author's transl)]. | pleuromutilins have an aegyptianellicidal efficacy. a significant chemotherapeutic influence on the course of the infection in chickens could only be achieved after repeated oral and intramuscular applications of at least 150 mg and 75 mg/kg body weight respectively. however, even at these concentrations the infections were not cleared. | 1979 | 575580 |
| survival of aegyptianella pullorum, anaplasma marginale and various parasitic protozoa following prolonged storage in liquid nitrogen. | various protozoa species were examined using in vivo and in vitro methods to determine their ability to survive prolonged periods of storage in liquid nitrogen. the following protozoan species were successfully recovered after they had been cryopreserved for a period over 10 years: trypanosoma lewisi, t. cruzi, t. congolense, t. brucei, t. rhodesiense, t. gambiense, t. evansi, t. equinum, t. equiperdum, leishmania donovani, plasmodium berghei, p. praecox (relictum), babesia rodhaini and b. canis ... | 1977 | 919686 |
| description of aegyptianella botuliformis n. sp. (rickettsiales: anaplasmataceae) from the helmeted guineafowl, numida meleagris. | aegyptianella botuliformis n. sp. (rickettsiales: anaplasmataceae) isolated from helmeted guineafowls numida meleagris from the kruger national park is described. the rickettsia occurs within a membrane-bound vacuole in the cytoplasm of erythrocytes with up to 8 organisms in a mature inclusion. the initial body resembles that of aegyptianella pullorum. the tightly packed, sausage-shaped intermediate forms are a distinctive morphological feature, seen as irregular, pleomorphic forms under light m ... | 1992 | 1513599 |
| broiler pulmonary hypertension syndrome. i. increased right ventricular mass in broilers experimentally infected with aegyptianella pullorum. | infection with the obligatory intra-erythrocytic anaplasma-like rickettsia aegyptianella pullorum in 4-week-old broilers at a moderate altitude of 1,200 m produced a significant increase in the mean relative right ventricular (rv) mass (rv: tv) from 0.23 in the controls to 0.31 in the infected group. this was accompanied by an increase in the number of birds suffering from severe rv hypertrophy from 14.3% in the controls to 50% in the infected group. pulmonary hypertension and subsequent rv hype ... | 1987 | 2957638 |
| avian pulmonary hypertension syndrome. iv. increased right ventricular mass in turkeys experimentally infected with plasmodium durae. | infection of young turkeys with plasmodium durae produced a significant increase in the mean relative right ventricular mass from 0.172 in the controls to 0.208 in the infected group. although turkeys react less strongly to hypoxia than broiler chickens, the similarity of this finding to that previously reported in broilers infected with aegyptianella pullorum suggests that the hypoxic effect of the anaemia produced by these blood parasites causes the pulmonary hypertension and subsequent right ... | 1988 | 2969087 |
| freeze-drying of aegyptianella pullorum. | heparinized whole blood, parasitized with aegyptianella pullorum, was collected from 2 fowls. buffered lactose peptone (blp) was added v/v as a stabilizer and the mixture lyophilized in 2 ml aliquots after rapid or slow freezing. at different stages during the freeze-drying process, as well as after lyophilization and reconstitution with 1.8 ml of sterile water, samples were taken and injected into pullets. infectivity was maintained throughout. however, the prepatent period was lengthened after ... | 1988 | 3393371 |
| isolation and identification of aegyptianella pullorum (rickettsiales, anaplasmataceae) in wild turkeys from north america. | isodiagnosis of blood from rio grande wild turkeys from southern texas revealed a small, intraerythrocytic rickettsia, aegyptianella pullorum carpano, 1928, in 24 of 300 samples. identification of this first isolate from north america was made using both light and transmission electron microscopy. it is suggested that the translocation of wild turkeys from texas to other states could spread this pathogen to both wild birds and domestic poultry. | 1985 | 4026738 |
