Anaplasma species are transmitted by ticks and cause diseases in humans and animals. These pathogens infect sheep, an economically important domestic animal worldwide. The current study was designed to characterize in 200 animals the infection with Anaplasma phagocytophilum and Anaplasma ovis and the genetic diversity of A. ovis strains ... Anaplasma is a genus of gram-negative, intracellular bacteria infecting different blood cells in animals. Three of the species infect the erythrocytes of ruminants, A. marginale and A. centrale most often infect cattle, while A. ovis primarily infects sheep and goats. Different species of wild ruminants can also become infected. Anaplasma ovis is the major cause of small ruminant anaplasmosis . Anaplasma ovis detection in this study (5.5%) was lower than previously reported detection rates in goats from South Africa (36.3%) , Sudan (60.1%) , and Tunisia (93.8%) . The differences in infection rates could be attributed to the difference in climatic conditions, vector ...

Although A. ovis may infect domestic sheep and goats without clinical Anaplasma ovis, A. centrale, or other as yet unidentified anaplasms may well occur in other ruminants. With the exception of black-tailed deer, the epidemiologic significance of anaplasmosis in ...

On a per province basis, A. ovis infection rates ranged from 7.4%–93.3% and 13.3%–100% in sheep and goats, respectively. Introduction. Anaplasmosis is an arthropod-borne disease of cattle and other ruminants which is caused by different geneses of Anaplasma species (Rickettsiales: Anaplasmataceae). 1 Five Anaplasma genuses including A. marginale, A. centrale, A. phagocytophilium, A. bovis and A. ovis are usually identified in Iranian cattle and sheep using molecular methods (through blood sampling). 2-7 ... Anaplasma ovis was demonstrated in all examined sheep keds, and from one pool of free-living deer keds. Rickettsia helvetica or other, unidentified rickettsiae were also present in one pool of sheep keds, and in four pools of deer keds from both red deer and roe deer. La anaplasmosis, causada por Anaplasma phagocytophilum es una zoonosis que además de afectar al hombre, puede provocar enfermedad en caballos (Equus caballus), burros (Equus africanus asinus), grandes y pequeños rumiantes (Bos taurus, Ovis aries, Capra aegagrus hircus), perros (Canis lupus

Dark-purple round or oval inclusions consistent with Anaplasmataceae morulae were observed in the cytoplasm of erythrocytes. Phylogenetic trees produced using different methods agreed that the organism detected in this study belongs to the genus Anaplasma, and suggested that it is most closely related to the cluster comprising A. centrale, A. capra, A. marginale and A. ovis.
Background: Anaplasma ovis infections can cause clinical symptoms in acute phase and lead to huge economic losses in flocks. The aim of the present study was to investigate the hematological and parasitological changes in experimental anaplasmosis in sheep with Iranian strain of A. ovis.

Even before the recent reclassification within the family Anaplasmataceae, the msp5 gene was known to be highly conserved among all Anaplasma species, (11) which, at that time, included A. marginale, A. centrale, and A. ovis (18).

Multiple infections with these four Anaplasma pathogens have been reported in many cases. We introduce a novel multiplex PCR for the ...

Recently a disease condition that involves sudden death of reindeer and cases involving fever, lethargy, and pale mucous membranes has been reported.

Anaplasma ovis was detected in 35.9% of the tested samples. Although in cattle the most pathogenic Anaplasma species are A. marginale and A. phagocytophilum (Durrani and Goyal 2012), A. ovis is the most commonly found Anaplasma in other ruminant species in Greece, it is potentially zoonotic and could cause disease in cattle (Chochlakis et al.

Anaplasma is a genus of obligate intracellular, gram-negative bacteria that infect blood cells of mammals. These bacteria can cause diseasesin vertebrates and the vertebrates may also serve as reservoirs (Rymaszewska and Grenda 2008). The Anaplasma species that infect and may cause disease in ani-mals are A. marginale, A. ovis, A. centrale, A ... Goats which have recovered from acute Anaplasma ovis infection remain seropositive, although infected erythrocytes cannot be detected by microscopic examination. Persistence of A. ovis 17 to 21 months following experimental infection was demonstrated by PCR detection of the msp-5 gene. Quantitative analysis of persistent rickettsemia over time showed that all levels were below the limit of ...

However, Anaplasma inclusion bodies were only observed in 32.1% of the tested animals. T. ovis were found in 88% of the inspected sheep by PCR, and 67.8% of them were detected microscopically, as well. Anaplasma mesaeterum is closely related to A ovis and may also cause disease in sheep and goats, however it appears to be less pathogenic for goats (Uilenberg et al., 1979; Nakamura et al., 1993). Despite widespread distribution and severe losses, effective control of anaplasmosis has not been achieved on a sustainable basis in most affected areas.
