Abstract
This Turkey-based study investigated the presence of various tick-borne microorganisms in a broad-range of host-seeking ticks (n = 1019) that exhibit both hunter and ambusher characteristics. All collected ticks were analyzed individually via PCR-sequencing, resulting in the identification of 18 different microorganisms: six Babesia spp., including one putative novel species (Ba. occultans, Ba. crassa, Ba. rossi, Babesia sp. tavsan1, Babesia sp. tavsan2, and Babesia sp. nov.); six SFG rickettsiae (Ri. aeschlimannii, Ri. s. mongolitimonae, Ri. slovaca, Ri. raoultii, Ri. monacensis, and Ri. hoogstraalii); two Borrelia burgdorferi sensu lato spp. (Bo. afzelii and Bo. lusitaniae); two unnamed Hepatozoon spp.; Theileria annulata; and Hemolivia mauritanica. This provided evidence for the natural transstadial survival of these tick-borne microorganisms in adult ticks (in addition a nymph) of Turkey. Surprisingly, this study determined the presence of five different microorganisms (Ba. crassa, Ba. rossi, Babesia sp. Ucbas, Hepatozoon sp., and Ri. hoogstraalii) in host-seeking Haemaphysalis parva adults, for which poor data exist on its vectorial competence. Therefore, this study provides important data indicating the potential vectorial capacity of Ha. parva. This study also revealed the presence of the close ecological and evolutionary relationships between two important vector ticks, Hyalomma marginatum and Hy. aegyptium and determined genetic variations (distinct phylogenetic divergences inside the main clades) in some pathogenic SFG rickettsiae that are found in these ticks. Additionally, the presence of two Babesia species described very recently in hares with unknown vectors, namely Babesia sp. tavsan1 and Babesia sp. tavsan2, were detected for the first time in ticks. Finally, two unnamed Hepatozoon spp. were detected in Haemaphysalis ticks and their phylogenetic positions were demonstrated. Consequently, this study provides important data on the diversity of tick-borne microorganisms in host-seeking ticks and on potentially novel microorganisms (Babesia and Hepatozoon species) and their possible vectors (Ha. parva, Ha. sulcata, Hy. aegyptium, Hy. marginatum, and Rh. turanicus).

Abstract
In this study, a total of 319 ticks were obtained from hedgehogs (Erinaceus concolor). All ticks were pooled into groups and screened by PCR for tick-borne pathogens (TBPs). PCR and sequence analyses identified the presence of a novel Babesia sp. in adult Haemaphysalis erinacei. In addition, the presence of natural transovarial transmission of this novel Babesia sp. was detected in Ha. erinacei. According to the 18S rRNA (nearly complete) and partial rRNA locus (ITS-1/5.8S/ITS-2) phylogeny, it was determined that this new species is located within the Babesia sensu stricto clade and is closely related to Babesia spp. found in carnivores. Furthermore, the presence of three pathogenic spotted fever group (SFG) rickettsiae was determined in 65.8% of the tick pools: Rickettsia sibirica subsp. mongolitimonae in Hyalomma aegyptium (adult), Hyalomma spp. (larvae), Rhipicephalus turanicus (adult), and Ha. erinacei (adult); Rickettsia aeschlimannii in H. aegyptium (adult); Rickettsia slovaca in Hyalomma spp. (larvae and nymphs) and H. aegyptium (adult). To our knowledge, this is the first report of R. sibirica mongolitimonae in H. aegyptium, Ha. erinacei, and Rh. turanicus, and the first report of R. slovaca in H. aegyptium. In addition, the presence of a single Hemolivia mauritanica haplotype was detected in H. aegyptium adults. Consequently, the presence of a novel Babesia sp. has been identified in a new candidate vector tick species in this study. Additionally, three SFG rickettsiae that cause infections in humans were identified in ticks collected from hedgehogs. Therefore, environmental wildlife monitoring for hedgehogs should be carried out for ticks and tick-borne pathogens in the region. Additionally, studies regarding the reservoir status of hedgehogs for the aforementioned pathogens must be carried out.

Abstract
Nymphs and larvae belonging to Ixodes spp. were collected from a red fox in Turkey. The ticks were identified morphologically and molecularly (16S rDNA PCR and phylogenetic analysis) as I. kaiseri. Sequence and phylogenetic analyses show that our I. kaiseri isolate is very similar to I. kaiseri isolates collected from Germany, Serbia, Romania, and Hungary. Therefore, the existence of I. kaiseri has been demonstrated for the first time in Turkey. More studies relating to the regional distribution and vectorial competence of I. kaiseri are needed.

Abstract
To date, no study has investigated Babesia ecology in wild boars, hares or foxes in Turkey. This study aimed to determine and characterize Babesia spp. in wild animals and their ticks. We identified a novel Babesia genotype and four known Babesia species in wild animals and their ticks. We detected Babesia spp. molecularly in hares for the first time. In addition, we identified B. vulpes in foxes for the first time in Turkey. The presence of B. rossi, B. crassa and B. occultans was also revealed in ticks collected from wild boars and hares. This is only the second report of B. rossi in ticks outside of Africa and suggests that B. rossi is circulating in ticks in Turkey. Therefore B. rossi poses a significant threat to domestic dogs. Here we demonstrate the role of wild animals in the life cycle of Babesia species in Turkey and contribute to Babesia ecological and taxonomic information.

Abstract
We aimed to determine the ticks of the Anatolian wild sheep and to define their tick-borne pathogens while molecularly studying their relationships with those of the domestic sheep. Furthermore, another aim of this study is to investigate tick paralysis resulting in the death of the Anatolian wild sheep. Ticks and blood samples were collected from the wild sheep whilst tick samples were also collected from hares, guinea fowls, chickens, and a turkey living in the Anatolian wild sheep breeding area. While PCR amplification was carried out for the detection of Babesia spp., Theileria spp. and Anaplasma spp. in blood samples, CCHF virus was screened in the tick samples in addition to the above-mentioned pathogens. Theileria spp. was detected in blood samples of 45 wild sheep. A total of 3494 ticks were collected from 52 Anatolian wild sheep, 5 hares, 5 guinea fowls, 2 chickens, and 1 turkey whereas 98 ticks were collected from the ground. B. ovis and T. ovis were detected in tick pools (Rh. bursa and H. excavatum) that were collected from the wild sheep. The paralysis was diagnosed in both of the hind legs of the newborn lambs infested with a great number of ticks. We also report that the tick species (H. excavatum and Rh. bursa) are determined to cause tick paralysis and tick toxicosis, which are associated with mortality especially in lambs. T. ovis and B. ovis were detected and studied for the first time in Anatolian wild sheep and in their ticks. The results of phylogenetic analyses showed that T. ovis and B. ovis isolates are genetically very close to the isolates that were previously obtained from the domestic small ruminants. We show that the Anatolian wild sheep can play the role of a reservoir for T. ovis. The presence of the CCHF virus has also been clearly shown and it has been observed that this virus, which is very pathogenic for humans, is anywise circulating in the region.

Abstract
Background The importance of tick-borne diseases is increasing all over the world, including Turkey. The tick-borne disease outbreaks reported in recent years and the abundance of tick species and the existence of suitable habitats increase the importance of studies related to the epidemiology of ticks and tick-borne pathogens in Turkey. The aim of this study was to investigate the presence of and to determine the infection rates of some tick-borne pathogens, including Babesia spp., Borrelia burgdorferi sensu lato and spotted fever group rickettsiae in the ticks removed from humans in different parts of Ankara. Methodology/Principal Findings A total of 169 ticks belonging to the genus Haemaphysalis, Hyalomma, Ixodes and Rhipicephalus were collected by removing from humans in different parts of Ankara. Ticks were molecularly screened for Babesia spp., Borrelia burgdorferi sensu lato and spotted fever group rickettsiae by PCR and sequencing analysis. We detected 4 Babesia spp.; B. crassa, B. major, B. occultans and B. rossi, one Borrelia spp.; B. burgdorferi sensu stricto and 3 spotted fever group rickettsiae; R. aeschlimannii, R. slovaca and R. hoogstraalii in the tick specimens analyzed. This is the report showing the presence of B. rossi in a region that is out of Africa and in the host species Ha. parva. In addition, B. crassa, for which limited information is available on its distribution and vector species, and B. occultans, for which no conclusive information is available on its presence in Turkey, were identified in Ha. parva and H. marginatum, respectively. Two human pathogenic rickettsia species (R. aeschlimannii and R. slovaca) were detected with a high prevalence in ticks. Additionally, B. burgdorferi sensu stricto was detected in unusual tick species (H. marginatum, H. excavatum, Hyalomma spp. (nymph) and Ha. parva). Conclusions/Significance This study investigates both the distribution of several tick-borne pathogens affecting humans and animals, and the presence of new tick-borne pathogens in Turkey. More epidemiological studies are warranted for B. rossi, which is very pathogenic for dogs, because the presented results suggest that B. rossi might have a wide distribution in Turkey. Furthermore, we recommend that tick-borne pathogens, especially R. aeschlimannii, R. slovaca, and B. burgdorferi sensu stricto, should be taken into consideration in patients who had a tick bite in Turkey. Ticks are widespread in over all Turkey. Primary tick-borne diseases (TBDs), such as theileriosis, babesiosis, and anaplasmosis, affecting animals have been known for a long time in Turkey. However, TBDs have become a major concern in humans in recent years due to the recent Crimean-Congo hemorrhagic fever outbreak in Turkey. We know that some TBDs like CCHF, Lyme borreliosis, spotted fever group rickettsiosis, babesiosis and anaplasmosis exist in this geography. However, the other diseases except for CCHF are neglected in patients. In this study, we aimed to investigate Babesia spp., Borrelia burgdorferi sensu lato and spotted fever group rickettsiae in ticks removed from humans in different parts of Ankara by using PCR and sequencing. The result of this study showed that 4 Babesia species, one B. burgdorferi sensu lato, and 3 spotted fever group rickettsia are detected in ticks. The most striking result of this study is that B. rossi, which is very pathogenic for dogs, was reported for the first time from a region that is out of Africa and in Ha. parva. Therefore, B. rossi should be considered in dogs in Turkey. Furthermore, we propose that R. aeschlimannii, R. slovaca, and B. burgdorferi sensu stricto should be taken into consideration in patients who had a tick bite in Ankara.

Abstract
Myiasis is a cause of urogenital parasitosis. In this study, a 29 year-old male patient who was admitted to our hospital with urinary discharge of worms has been presented. Larvae were examined parasitologically and urogenital myiasis caused by Psychoda albipennis larvae was diagnosed. No other pathological findings were detected in the patient and the symptoms resolved spontaneously within a few days. Despite the fact that urinary myiasis is very rare in humans, it should be considered in patients with urinary complaints. Apparently, a quick recovery without treatment is possible in most cases.

Abstract
OBJECTIVE This study has been planned to investigate some biological features of Hyalomma marginatum, which is one of the important vectors in the world and in our country. METHODS The study started with the adult H. marginatum which were collected from cattle in the field and attempts were made for these to be adapted to the laboratory by breeding in the laboratory throughout a generation. Unfed adult ticks and unfed larvae were bred on the rabbit ear while unfed nymphs were bred on the calf ear. The biologic development stages of this tick kind, except for sucking blood stage, passed in an incubator which was at a temperature of 28°C and 85% relative humidity, while the unfed active stages passed in an incubator which was at 18°C and 85% relative humidity to conserve for a long time. RESULTS Unfed females on rabbits were full and fell in approximately 15 days, began to ovulate 20.5 days later and ovulated for 16 days. The larvae which hatched out approximately 29 days later became active in 8.5 days. These larvae sucked blood from rabbits for 14.5 days and abandoned these animals as full nymphs. Unfed adult ticks, which existed as a result of these nymphs casting off their skin in approximately 26 days, became active by completing their cutinization in approximately 10 days. CONCLUSION At the end of the study, it was determined that H. marginatum showed 2 different behaviors in rabbits. According to this, the total life cycle in the laboratory environment changed by between 97 and 182 days and lasted approximately 138.5 days.

Abstract
In this study, Hyalomma anatolicum anatolicum male ticks were subjected to gamma radiation with a dose of 10 Gy emitted by a gamma-ray source of Caesium 137. Female ticks were divided into 3 groups and placed in rabbit ears to feed. In the first group, the females fed with normal and irradiated males, in the second group females fed only with irradiated males and in last group females fed with normal males. Biological parameters such as the feeding period, weights, period of time from dropping until egg-laying began, the number of eggs and the number of larva hatching from eggs were recorded. With the results of statistical analysis it was found that the average egg laying period of females in the second group was clearly less (22.77 days) than other groups and the difference between these groups was statistically important (P < 0.05). After evaluation of numbers of larva, also there was a statistically important difference between the groups and the average number of larva was clearly higher (2519.30) in third group than other groups. In conclusion, in this study it was found that irradiated males could not compete with normal males in mating with females and because of this they couldn't affect the feeding and reproductivity of females.

Abstract
Bovine babesiosis is a widespread disease occurring throughout tropical and subtropical regions and causes serious economical losses. Transmitted by ticks, Babesia species attract attention as the cause of disease and parallel the seasonal activity of ticks, in spring-summer months when temperatures increase. Ticks, that transmit the disease, belong to the Ixodidae family (pasture ticks-hard ticks) and affect cattle that go out to pasture during the warm season. In this case, babesiosis was reported from a barn in Ankara, the temperatures had decreased to under 0 degrees C and it was snowing in February. The cattle hadn't been in a pasture for the past 3 months.

Abstract
We report the case of urogenital myiasis caused by Psychoda albipennis in a 50-year-old female patient who had a urinary bladder surgery at Osmangazi University, Faculty of Medicine. After the surgery she returned to the hospital claiming that she had seen small, white colored, active particles in her urine. The examination of the material revealed the presence of 3 larvae, which were identified as the fourth stage of the moth fly Psychoda albipennis. The complaints of the patient disappeared after antibiotic and antiseptic treatment of the infested area. This case is of special interest due to the fact that parasites were seen after urinary bladder surgery.

Abstract
This study was carried out on 45 stool specimens, consisting of 18 samples from children with diarrhea and 27 samples from diarrheic calves. Samples were screened by both carbol fuchsin staining and nested PCR for presence of Cryptosporidium spp. Using the carbol fuchsin staining method, we detected a total of 4 (8.9%) positive samples out of 45; of these 3 (11.2%) were from calf samples and 1 (5.6%) from a child. Nested PCR detected a total of 9 (20.0% positive samples out of 45 including 8 (29.7%) from calf samples and 1 (5.6%) from a child. Although the staining method revealed a 100% specificity, it was deficient in sensitivity (44.0%) compared to nested PCR. The study showed that nested PCR is an acceptable method for studying the etiology of doubtful diarrheal cases.

Abstract
This study was carried out to determine the status of tick infestation of cattle in the Kayseri region in Turkey. Eight hundred and sixty-six cattle and their barns in 12 localities were examined during the period of June 2000-November 2001, where 188 (21.7%) of which were infested by ticks. A total of 1,585 ticks consisting of Rhipicephalus turanicus (2.27%), R. bursa (2.14%), R. sanguineus (0.94%), Hyalomma marginatum (17.16%), H. anatolicum excavatum (24.73%), H. a. anatolicum (19.62%), Dermacentor niveus (1%), Boophilus annulatus (16.71%), Ornithodorus lahorensis (0.25%), Hyalomma sp. nymphs (7.31%), and Boophilus annulatus nymphs (7.82%) were collected. Seasonal fluctuation of ticks was also determined in this region. Rhipicephalus species were generally found in spring, others like Hyalomma in late spring, summer, and early autumn, B. annulatus in September, October, and December, D. niveus in December, January, and February, and O. lahorensis in December. Immature forms (nymphs) of Hyalomma species were found in summer and autumn, while B. annulatus nymphs were observed in October, November, and December.

Abstract
Selamectin, a novel avermectin compound, was evaluated for its efficacy against naturally occurring infestations of Psoroptes cuniculi and Sarcoptes scabiei. A total of 42 New Zealand rabbits with psoroptic mange and 37 Angora rabbits with sarcoptic mange were used in the present study. On day 0, infested rabbits were treated topically with either selamectin at minimum dose of 6 mg kg(-1) (6-18 mg kg(-1) for New Zealand rabbits, n = 31 and 10-12 mg kg(-1) for Angora rabbits, n = 23) or vehicle only (control groups, n = 11 for New Zealand rabbits, n = 14 for Angora rabbits). The efficacy of selamectin was assessed both clinically and parasitologically by the presence or absence of viable mites. Rabbits were scraped for sarcoptic mites on days 7, 14, 28, 42 and 56 and had otoscopeic and/or microscopic examination for the detection of Psoroptes mites on days 7, 14, 42 and 56. Fisher's exact test was used to assess differences between the vehicle and selamectin treatment in the number of rabbits without mites (cure rates) on each assessment date. It was found that significantly fewer selamectin-treated rabbits had mites detected on skin scrapings (for S. scabiei) or otoscopeic and/or microscopic examination (for P. cuniculi) (P < 0.01) than the vehicle group. Results of the present study suggest that selamectin is effective against naturally infestations of P. cuniculi and S. scabiei in rabbits.

Abstract
This study was undertaken for the determination of Sarcocysts species in sheep slaughtered in Kirikkale Municipality Slaughterhouse. For this study, oesophageal, diaphragm and intercostal muscles were collected from randomly selected 112 sheep out of 1131 sheep (814 sheep and 317 lambs) that were slaughtered from October 2005 to May 2006. The samples were examined for macro and microcyst of Sarcocysts spp. Macrocysts and microcysts were found in 58.92% of the overall samples. Microcysts were found in 47.32% and macrocysts were perceived in 20.53% of the sheep that were under examination. The distribution of the microcysts with respective to the age of the sheep was studied and it has been observed that 16.12% (5 in every 31 lambs) of the lambs under 1 year old and 59.25% (48 in every 81 sheep) of the sheep equal or older than 1 year old had possessed microcysts. Sarcocystis ovicanis (47.32%) and S. arieticanis (1.23%) were the species with the highest and lowest number of recurrences respectively. Macrocysts were observed in every sheep over one age. In addition, randomly selected oesophagi with macrocyst were examined histopathologically. Sarcocystis sporocysts were not found in dog feces.

Abstract
In this study, male ticks belonging to the Hyalomma anatolicum anatolicum species were subjected to gamma radiation doses of 5, 10, 15, 20 and 50 Gy, emitted by a gamma-ray source of Caesium 137. In females that fed with these male ticks, proportional to the increase in radiation dose, the period of feeding was found to shorten. A decrease was demonstrated in the number of engorged female ticks, engorgement weights, number of laying ticks and number of eggs. The hatching period of larvae from eggs was found to increase despite the decrease in the number of hatched larvae. Moreover no larvae were observed to hatch from any of the eggs of female ticks treated with a radiation dose of 50 Gy. Similarly, proportional to the applied dose of radiation, rates of viability and activity were observed to decrease in male ticks. In conclusion, taking into consideration the feeding periods and fertility rates of female ticks as indicators of male activity, this study has demonstrated that in combating with H. anatolicum anatolicum, radiation may be successful and a radiation dose of 10 Gy is most favorable.

Abstract
In the first part of the present study, a total of 109 faeces samples collected from calves suffering from diarrhoea were examined for Cryptosporidium parvum oocytes and 39 (35.8%) of them were found to be positive. On the basis of oocyte counts, 14 (36%) samples were assessed as mildly infected and 25 (64%) samples as heavily infected. The occurrence of the disease was more common in winter (56.4%) than during other seasons (autuma 0%, summer 15.4% spring 28.2%. In the present study, the ionophore polyetherantibiotic Lasalocid-Na, that is licensed as a feed additive (Bovatec, 15% Lasalocid-Na, Roche AG) in Turkey, was administered to 11 calves naturally infected with Cryptosporidium and its therapeutic effect was evaluated. Lasalocid-Na (8 mg/ kg BW) was given once daily for 3 days added to the milk. The clinical parameters of infected calves were evaluated before and 3 days after the treatment in 24 hour intervals. The oocyst counts of faeces of calves with cryptosporidiosis were between 15 x 10(6) and 96 x 10(6)/mL before treatment. No oocystes were found in faecal samples of 3 calves (27.3%) after 48 hours and 4 (40%) calves after 72 hours of treatment, respectively. The number of oocytes in the faeces of the remaining calves varied between 90 and 1.2 x 10(6)/mL during the respective period. The number of oocystes before treatment was significantly higher than the number of oocytes after treatment. One of the calves died 56 h after the first treatment despite the treatment. The pH of venous blood was decreased prior to treatment as expected. The lowest pH was 6.83, the lowest bicarbonate concentration was 3.80 mmol/l and the lowest base excess was -31.2 mmol/l. After the treatment, pH, pCO2, HCO3- and BE values of the venous blood increased significantly and reached physiological values before discharge. The differences between the values assessed before the treatment and at the 2nd, 3rd, and 4th sampling time were statistically significant. Number of leucocyte and haemoglobin concentration before the treatment were significantly higher than the values after treatment (p < 0.01). These values returned back to physiological ranges 72 hours after first treatment. Lasalocid-Na was rather well tolerated. Side effects such as the decline of the suckling reflex and intoxication symptoms in respect to present administration form and dosage were found only in one calf (9%). Treatment procedure in the present study with Lasalocid-Na was found to be suitable in combination with an adequate infusion therapy for the treatment of calves on farms with problems related to cryptosporidiosis. Although the use of Lasolacid-Na for the treatment of Cryptosporidium infection in the EU is banned, it might be used as an alternative drug outside of the EU since it has a successful effect for preventing reinfections.

Abstract
This study has been carried out to show that myiasis flies can grow on the carelessly discarded remains of slaughtered cattle. For this purpose, 11 larvae that were found on a piece of cattle remains that weighed 250 grams was put into 70% alcohol for identification; and the remaining 20 larvae were put into a pot containing sand on the bottom. The pot was covered with a piece of cloth in order to let them complete their growth. Later the pot was put outside so that the larvae could develop under natural conditions and daily growth of the larvae was determined. Pupas were produced by the larvae after 21 days and adult flies, after 28 days. With the help of identification keys, it was determined that out of the eleven larvae that were initially put into 70% alcohol, 5 larvae were third period Calliphora vicina and 3 larvae, second period. The remaining 3 larvae were third period Muscina stabulans. All of the 18 flies that developed from the 20 larvae in the covered pot outside were C. vicina.

Abstract
An epidemiological survey for Theileria annulata infection was conducted in 12 selected villages around Ankara in Central Anatolia, Turkey, during the period April 1990 to January 1993. During the survey, 198 cattle of 30 local breeds, 84 Holstein-Friesian x local breeds and 84 Holstein-Friesian breed were examined for antibodies to T. annulata and the presence of the vector ticks. Four species of Hyalomma ticks were identified: Hyalomma anatolicum anatolicum, Hyalomma anatolicum excavtum, Hyalomma detritum and Hyalomma marginatum marginatum. Salivary gland staining indicated that infected adult ticks of all four species were present and, therefore, were implicated in the transmission of tropical theileriosis in the field. Generally, the Hyalomma infestation rate was low, with the heaviest infestations occurring on the older animals. Young adults and calves had very low infestation rates. Most ticks seen on cattle were adults, very few nymphs were found. The blood smear and serological examination of the 198 cattle conducted in March, before the start of the first disease season, showed that the prevalence of piroplasmosis was 11.1% (22 out of 198) and the seroprevalence of T. annulata was 10.6% (21 out of 198). Forty-three animals were then excluded from the study because they were seropositive and/or harboured piroplasms. Ninety-two seronegative animals showed piroplasmosis (92 out of 155) and 34 seronegative animals became seropositive for T. annulata (34 out of 155) during the three disease seasons. One animal became clinically ill with tropical theileriosis and required treatment. The incidence of cattle showing piroplasmosis and disease in the total study sample was 50.7% and 0.5% per disease season, respectively. The seroconversion rate of new infection with T. annulata in the total study was 14.3% per animal season. The number of cattle showing piroplasmosis was much greater than the number of seropositive cattle, which may indicate the presence of another species of Theileria. The two different management systems encountered in the study were considered to have influenced the tick infestation levels.

Abstract
In this comparative study unfed nymphs of four Hyalomma tick species (Hyalomma anatolicum anatolicum, Hyalomma anatolicum excavatum, Hyalomma detritum and Hyalomma marginatum marginatum) were allowed to engorge on calves experimentally infected with Theileria annulata. The infection prevalence in the salivary glands of the adult female and male ticks of each Hyalomma species used in the study were assessed. The infection prevalence with T. annulata was high and did not vary markedly in the four Hyalomma tick species. The mean number of infected acini per tick in female and male ticks was different with female ticks having higher numbers of infected acini than the male ticks. The sex difference was more significant between H.a. anatolicum and H.a. excavatum than between H. detritum and H.m. marginatum. This study clarifies the roles of four Hyalomma tick species, and their sex, in the development of T. annulata.

Abstract
A serological survey using Indirect Fluorescent Antibody Test (IFAT) for Babesia ovis infection of sheep has been carried out in different geographical regions of Turkey. The results indicated that 71.6% of 141 sheep in Black Sea region, 70.9% of 93 sheep in central Anatolia, 80.2% of 96 sheep in Aegean region and 55.7% of 122 sheep in eastern Anatolia were seropositive. This means that B. ovis infection is endemic throughout Turkey. In addition, occurrence of B. ovis, B. motasi, Theileria hirci, T. recondita and Anaplasma ovis infections in sheep and goats has been reported previously in Turkey as well. However further studies are needed to obtain more information about the agents to keep the infection under control.

Abstract
Cerebral myiasis with a 10-day history of convulsions due to an intracerebral hematoma caused by a Hypoderma bovis larva is reported in an 8-year-old child. Computerized tomography (CT) showed the hematoma in a right parieto-occipital location. The H. bovis larva and the extensive intracerebral hematoma were discovered during surgery. Among human parasitoses, cerebral myiasis is rare: a review of the literature revealed only two reports, one published in 1969 and one in 1980. This is the first case that has been diagnosed as cerebral myiasis with exact identification of the Hypoderma bovis larva both from the CT scans and at surgery in a patient during life.
