Ticks (Acari: Ixodida) parasitizing humans in Corum and Yozgat provinces, Turkey.

In order to identify ticks infesting humans in Corum and Yozgat provinces in Turkey, a total of 2110 ticks representing 14 species were collected on humans, between June and September 2009. Of those, 1551 (687♂, 450♀, 407 nymphs, 7 larvae) were collected from Corum and 559 (330♂, 180♀, 49 nymphs) were collected from Yozgat. The majority of ticks (n = 1121, 53.1 %) was Hyalomma marginatum. Other common ticks infesting humans were Dermacentor marginatus (n = 209, 9.9 %) and Rhipicephalus turanicus sensu lato (n = 145, 6.9 %) in the study area. In addition, a total of 386 immature Hyalomma were found on humans in Corum (335 nymphs, 7 larvae) and Yozgat (44 nymphs). Ixodes laguri and Haemaphysalis erinacei taurica were recorded for the first time in Corum. To the best of our knowledge, this study is the first detailed investigation on ticks infesting humans in Corum and Yozgat, except individual or incidental records. The present study provides useful information for those concerned with ticks and tick-borne diseases in Turkey.

A survey of ticks (Acari: Ixodida) infesting some wild animals from Sivas, Turkey.

In order to determine the species composition of infesting ticks, between 2011 and 2012 a total of 1118 wild animals were captured from various regions of Zara, Sivas province, Turkey. A total of 138 ticks were obtained from the 58 host animals. Ticks were identified as Dermacentor marginatus (Sulzer), Haemaphysalis erinacei taurica Pospelova-Shtrom, Haemaphysalis parva (Neumann), Haemaphysalis punctata Canestrini and Fanzago, Haemaphysalis sulcata Canestrini and Fanzago, Hyalomma marginatum Koch, Ixodes laguri Olenev, Ixodes ricinus (L.), Ixodes vespertilionis Koch and Rhipicephalus turanicus Pomerantzev. To the best of our knowledge, there are several new host records for D. marginatus, H. e. taurica and I. laguri. In addition, I. vespertilionis was recorded for the first time in the Central Anatolian Region in Turkey, whereas I. laguri and H. e. taurica are firstly reported in Sivas.

Molecular detection of spotted fever group rickettsiae in ticks removed from humans in Turkey.

A total of 229 attached hard ticks were collected from humans in Yozgat province (Turkey) in 2009. All ticks were individually examined for the presence of Spotted Fever Group (SFG) rickettsiae using the polymerase chain reaction (PCR) targeting rickettsial citrate synthase (gltA) and outer membrane protein (ompA) genes. Rickettsial DNA was detected in 24 (10.5%) tick samples belonging to Dermacentor marginatus (Sulzer) (9 males, 3 females), Hyalomma marginatum Koch (8 males, 2 females) and Haemaphysalis parva (Neumann) (2 males). Four SFG rickettsiae were identified: Rickettsia aeschlimannii in H. marginatum, Rickettsia raoultii and Rickettsia slovaca in D. marginatus; Rickettsia hoogstraalii in H. parva ticks. With the present study, the presence of SFG rickettsiae in ticks was reported in Yozgat province for the first time.
