[Determination of tick species and treatment of cows, sheep and goats in the Sivas-Zara region]. / Sivas-Zara yöresindeki sigir, koyun ve keçilerde kene türlerinin belirlenmesi ve sagaltimi

The purpose of this study was to examine tick infestation in cattle, sheep and goats in the Zara-Sivas region for one year and to determine the epizootiology of the tick species as well as to investigate treatment of the infested animals. Tick infestation was detected in 71 (29.6%) out of 240 cattle, 66 (24.0%) out of 275 sheep and 50 (19.9%) out of 252 goats in the Zara region. It has been shown that the tick infestation on cattle included Haemaphysalis parva (33.8%), Dermacentor marginatus (2.8%), Boophilus annulatus (21.1%), Haemaphysalis concinna (15.5%), Hyalomma marginatum (19.7%) and Rhipicephalus bursa (7%). Those on sheep included Dermacentor niveus (18.2%), Dermacentor marginatus (31.8%), Haemaphysalis parva (13.6%), Haemaphysalis concinna (4.5%), Hyalomma marginatum (4.5%) and Rhipicephalus bursa (27.3%). Those on goats included Dermacentor niveus (4%), Dermacentor marginatus (12%), Haemaphysalis parva (40%), Haemaphysalis concinna (2%), Boophilus annulatum (4%), Hyalomma marginatum (6%) and Rhipicephalus bursa (32%). Ivermectin was administered to the infested animals in a dose of 200 microg/kg subcutaneously. The administration of the ivermectin was effective. As a result, it has been shown that the tick infestation is present in cattle, sheep and goats in Zara region, the tick species differ according to the season and administration of ivermectin was an effective treatment.

[Investigation of vectors for Borrelia burgdorferi and Lyme seropositivity in Sivas region]. / Sivas yöresinde Borrelia burgdorferi vektörlerinin ve lyme seropozitifliginin arastirilmasi.

The aims of this study were to investigate the presence of vector ticks for Borrelia burgdorferi and to determine the seropositivity of lyme disease in Sivas region of Middle Anatolia. A total of 10,303 ticks were collected and classified at genus level, however, none of them belonged to Ixodes genus, the vector of B. burgdorferi. For the seroepidemiological study, serum samples were collected from 270 subjects who inhabited in rural area and raised livestock, and from 135 subjects as the control group who inhabited in urban area and have no livestock story. The samples were screened for the presence of B. burgdorferi IgG antibodies with a commercial enzyme immunoassay kit (ImmunoWell Borrelia, Genbio, San Diego). As a result, one subject in the each group (0.4% and 0.7%, respectively) yielded positive result, however as these sera gave positive reaction in rapid plasma reagin (RPR) test, these were evaluated as cross-reactivity (false positivity). These results indicated that lyme disease is not endemic in our region since neither Ixodes genus ticks nor seropositive subjects were detected.
