molecular epidemiology of the emerging zoonosis agent anaplasma phagocytophilum (foggie, 1949) in dogs and ixodid ticks in brazil.anaplasma phagocytophilum is an emerging pathogen of humans, dogs and other animals, and it is transmitted by ixodid ticks. the objective of the current study was a) detect a. phagocytophilum in dogs and ixodid ticks using real-time polymerase chain reaction (qpcr); and b) determine important variables associated to host, environment and potential tick vectors that are related to the presence of a. phagocytophilum in dogs domiciled in rio de janeiro, brazil.201324330631
detection of anaplasma phagocytophilum in brazilian dogs by real-time polymerase chain reaction.anaplasma phagocytophilum was detected in dogs from brazil in the municipalities of seropédica and itaguaí, rio de janeiro state, by real-time polymerase chain reaction (pcr) using sybr green to detect the amplification. of 253 samples, 18 (7.11%) were positive, with a threshold cycle (ct) ranging from 31 to 35 cycles. the pcr product from a positive sample was cloned and sequenced. the sequence obtained demonstrated 100% identity with other a. phagocytophilum sequences published in the genbank ...201121908321
