For general laboratory and research use only
Anaplasma centrale is a Gram-negative bacterium of the Rickettsiales order lacking a
traditional cell wall. The double-stranded, circular genome of this species is around 1.2 Mb
in length, coding for over 900 proteins. Infection causes a mild form of anaplasmosis in
cattle and has been used as a vaccine against A. marginale. It occurs primarily in warm
tropical and subtropical areas.
A. centrale is most commonly transmitted by ticks such as Boophilus spp. and
Dermacentor spp but can also be transmitted via contaminated needles, dehorning
equipment, castrating knives, tattoo instruments, biting flies and mosquitoes.
It multiplies within the tick vectors before being passed to cattle when the ticks feed. The
bacteria infect the erythrocytes, thrombocytes and leukocytes of the cattle and mainly
multiply within the cells of the spleen and liver. The host immune system destroys infected
cells leading to anemia.
Cattle infection presents with fever, loss of appetite, jaundice, anemia and respiratory
problems. The infected animal may recover from the clinical symptoms of the infection but
will remain a carrier of the bacteria, passing it back to ticks during feeding. Immunity can
be passed to calves via milk feeding and offers protection to infants. In severe case, the
infection may result in animal fatality.
Introduction to Anaplasma centrale
The PCR Max qPCR Kit for Anaplasma centrale (A.centrale) genomes is designed for the
in vitro quantification of A.centrale genomes. The kit is designed to have the broadest
detection profile possible whilst remaining specific to the A.centrale genome.
The primers and probe sequences in this kit have 100% homology with a broad range of
A.centrale sequences based on a comprehensive bioinformatics analysis.
