active surveillance of anaplasma marginale in populations of arthropod vectors (acari: ixodidae; diptera: tabanidae) during and after an outbreak of bovine anaplasmosis in southern manitoba, canada.bovine anaplasmosis is the disease caused by the bacterium anaplasma marginale. it can cause production loss and death in cattle and bison. this was a reportable disease in canada until april 2014. before then, infected herds were quarantined and culled, removing infected animals. in north america, a. marginale is biologically vectored by hard ticks (acari: ixodidae), dermacentor variabilis and d. andersoni. biting flies, particularly horse flies (diptera: tabanidae), can also act as mechanical ...027127345
genetic diversity of tick-borne rickettsial pathogens; insights gained from distant strains.the ability to capture genetic variation with unprecedented resolution improves our understanding of bacterial populations and their ability to cause disease. the goal of the pathogenomics era is to define genetic diversity that results in disease. despite the economic losses caused by vector-borne bacteria in the order rickettsiales, little is known about the genetic variants responsible for observed phenotypes. the tick-transmitted rickettsial pathogen anaplasma marginale infects cattle in tro ...025364572
blood parasites of livestock in certain regions in saudi arabia.blood samples from camels, sheep, goats and cattle from six regions in saudi arabia were examined for blood parasites. asir region camels were disinfected while those of the eastern, jazan, northern frontiers, riyadh and tabouk regions were infected with trypanosoma evansi (5-40%), those of riyadh and the eastern regions were infected with dipetalonema evansi (1-6%) and those of the eastern, jazan and riyadh regions were infected with eperythrozoon species (8-20%). sheep and goats of all tested ...023961044

the nature of bands in parasitized bovine erythrocytes.anaplasma marginale is the etiological agent of a hemolytic disease of cattle, known as anaplasmosis. the organism appears as a marginal inclusion in parasitized erythrocytes, but certain isolates also have bands associated with the inclusion. inclusions and associated bands in parasitized erythrocytes in the liver and peripheral circulation were studied by light microscope cytochemistry and electron microscopy. bands were comet- and dumbbell-shaped by light microscopy and were stained by techni ...19655857258

exacerbation of latent erythrocytic infections in deer following splenectomy.eight adult deer and 4 fawns, from wild populations, were splenectomized and observed for evidence of hemo-parasitic relapses. the animals were maintained indoors under tick-free conditions and in the absence of known arthropod vectors. following splenectomy 2 adult deer and 2 fawns developed acute eperythrozoon infections, 3 adult deer developed acute theileria infections, 2 adult deer developed a demonstrable anaplasma marginale parasitemia, and 1 adult deer exhibited a low level parasitemia o ...19674229931
evidence of lactate dehydrogenase in anaplasma marginale.extracts from preparations of partially purified anaplasma marginale revealed low levels of lactate dehydrogenase (ldh). enzyme inhibition by immune sera further indicated that a. marginale possesses a protein moiety the same as that of the normal red blood cell (rbc), although data suggested an alteration of ldh(1) from that observed in normal rbc. bimodal isozyme distribution was detected after electrophoresis of the extracts. one isozyme approached the cathode and the other the anode, and bot ...19676025428

isolation of plasma membrane fragments from hela cells.a method for isolating plasma membrane fragments from hela cells is described. the procedure starts with the preparation of cell membrane "ghosts," obtained by gentle rupture of hypotonically swollen cells, evacuation of most of the cell contents by repeated washing, and isolation of the ghosts on a discontinuous sucrose density gradient. the ghosts are then treated by minimal sonication (5 sec) at ph 8.6, which causes the ghost membranes to pinch off into small vesicles but leaves any remaining ...19694239370
