(Universidade Federal de Minas Gerais (UFMG), Escola de Veterinária, 2006-12-01)
Relata-se o caso de um bovino com, aproximadamente, seis horas de vida, apresentando histórico de febre, apatia, inapetência e desconforto ocular. No exame oftálmico rotineiro, encontraram-se valores do teste da lágrima ...
Low genetic diversity of Anaplasma marginale in calves in an endemic area for bovine anaplasmosis in the state of São Paulo, Brazil
(Elsevier B. V., 2015-08-20)
Major surface protein 1a has been used as a marker for genetic stability in identifying geographical isolates of Anaplasma marginale. We conducted a longitudinal study to ascertain the genetic diversity of A. marginale in ...
Anaplasma phagocytophilum Inhibits Apoptosis and Promotes Cytoskeleton Rearrangement for Infection of Tick Cells
(American Society for Microbiology, 2013-07)
Anaplasma phagocytophilum causes human granulocytic anaplasmosis. Infection with this zoonotic pathogen affects gene expression in both the vertebrate host and the tick vector, Ixodes scapularis. Here, we identified new ...
Risk factors for anaplasmosis in dairy cows during the peripartum
(Springer, 2014-02-01)
Anaplasma marginale is endemic in tropical and subtropical areas around the world. Some studies have suggested that cows during peripartum may present a transient immunosuppression state and development of clinical signs ...
Evaluation of a frozen trivalent attenuated vaccine against babesiosis and anaplasmosis in Brazil
(New York Acad Sciences, 1998-01-01)
Transplacental transmission of bovine tick-borne pathogens: Frequency, co-infections and fatal neonatal anaplasmosis in a region of enzootic stability in the northeast of Brazil
(2016-03-01)
Bovine tick-borne disease (TBD) constitutes a worldwide group of diseases that result in great losses for dairy and beef cattle. With regard to the epidemiological profile of the diseases, the importance of transplacental ...
High genetic diversity and superinfection by Anaplasma marginale strains in naturally infected Angus beef cattle during a clinical anaplasmosis outbreak in southeastern Brazil
(2022-01-01)
Anaplasma marginale is an obligate intracellular Gram-negative bacterium that is parasitic to erythrocytes and is the main agent of bovine anaplasmosis. This disease causes severe anemia and reduces weight gain and milk ...
