Molecular detection of vector-borne bacteria and protozoa in healthy hunting dogs from Central Italy

Objective:To determine the pi’evalence of vector-bome bacteria and protozoa in hunting dogs living in Central Italy.Methods:Molecular testing was executed on DNA which was extracted from blood specimens collected from 117 asymptomatic dogs to detect Anaplasma phagocytophilum,Babesia canis(B.canis),B...

Description
Summary:Objective:To determine the pi’evalence of vector-bome bacteria and protozoa in hunting dogs living in Central Italy.Methods:Molecular testing was executed on DNA which was extracted from blood specimens collected from 117 asymptomatic dogs to detect Anaplasma phagocytophilum,Babesia canis(B.canis),Bartonella spp..Coxiella burnetii(C.burnetii).Ehrlichia canis.Hepatozoon canis.and Leislnnania infantum.Results:A total of 48 dogs(41.0%) were infested by Ixodes ricinus and Rhipicephalus sanguineus ticks.Tick-borne infections were observed in 64(54.7%) animals.More in detail.38 dogs(32.5%) screened positive for Hepatozoon canis,24(20.5%) for Bartonella rinsonii subsp.berkhoffii.20(17.1%) for Leishmania infantum,6(5.1%) for C.burnetii,5(4.3%) for B.canis(3 B.canis vogeli and 2 B.canis canis),3(2.5%) for Anaplasma phagocytophilum,and 2(1.7%) for Ehrlichia canis.Mixed infection by 2 agents occurred in 17(14.5%) subjects,by 3 agents in 7(6.0%) dogs,and by 4 agents in 1(0.9%) animal.Conclusions:The results demonstrated that several vector-borne pathogens were circulating in this region and dogs infected by these agents were usually asymptomatic.A relevant finding was the presence of DNA of C.burnetii,a severe zoonotic agent,in the 5.1% of tested dogs,which can be source of infection for their owners not only through tick bites,but also directly with urine,feces and birth products.
