The list of tick-borne pathogens is long, varied and includes viruses,
bacteria, protozoa and nematodes. As all of these agents can exist in
ticks,
their co-infections have been previously reported. We studied co-infections
of emerging bacterial pathogens (Borrelia burgdorferi sensu lato, Anaplasma
phagocytophilum and Francisella tularensis) in Ixodes ricinus ticks in
Serbia.
Using PCR technique, we detected species-specific sequences, rrf-rrl rDNA
intergenic spacer for B. burgdorferi s.l., p44/msp2 paralogs for A.
phagocytophilum, and the 17 kDa lipoprotein gene, TUL4, for F. tularensis,
respectively, in total DNA extracted from the ticks. Common infections with
more than one pathogen were detected in 42 (28.8%) of 146 infected I.
ricinus ticks.
Co-infections with two pathogens were present in 39 (26.7%) of infected
ticks.
Simultaneous presence of A. phagocytophilum and different genospecies of B.
burgdorferi s.l. complex was recorded in 16 ticks, co-infection with
different B. burgdorferi s. l. genospecies was found in 15 ticks and eight
ticks harbored mixed infections with F. tularensis and B. burgdorferi s.l.
genospecies. Less common were triple pathogen species infections, detected
in three ticks, one infected with A. phagocytophilum / B. burgdorferi s.s.
/
B. lusitaniae and two infected with F. tularensis / B. burgdorferi s.s. /
B.
lusitaniae. No mixed infections of A. phagocytophilum and F. tularensis
were
detected.
