In vitro feeding of all life stages of two-host Hyalomma excavatum and Hyalomma scupense and three-host Hyalomma dromedarii ticks.

Ticks are blood-sucking ectoparasites and can transmit various pathogens of medical and veterinary relevance. The life cycle of ticks can be completed under laboratory conditions on experimental animals, but the artificial feeding of ticks has attracted increased interest as an alternative method. This study represents the first report on the successful in vitro feeding of all life stages of two-host tick species, Hyalomma scupense and Hyalomma excavatum, and the three-host tick Hyalomma dromedarii.

In vitro feeding of Hyalomma excavatum and Hyalomma marginatum tick species.

The rearing of ticks is an important technique for studies aiming to elucidate the course and pathogenesis of tick-borne diseases (TBDs). TBDs caused by protozoans (Theileria, Babesia) and bacteria (Anaplasma/Ehrlichia) impose a serious constraint upon livestock health and production in tropical and sub-tropical regions where the distributions of host, pathogen, and vector overlap. This study focuses on Hyalomma marginatum, one of the most important Hyalomma species in the Mediterranean region, being a vector of the virus that causes Crimean-Congo haemorrhagic fever in humans, together with H.

Arthropod vectors of disease agents: Their role in public and veterinary health in Turkiye and their control measures.

Mosquitoes, sandflies, and ticks are hematophagous arthropods that pose a huge threat to public and veterinary health. They are capable of serving as vectors of disease agents that can and have caused explosive epidemics affecting millions of people and animals. Several factors like climate change, urbanization, and international travel contribute substantially to the persistence and dispersal of these vectors from their established areas to newly invaded areas.

Selection of genotypes harbouring mutations in the cytochrome b gene of Theileria annulata is associated with resistance to buparvaquone.

Buparvaquone remains the only effective therapeutic agent for the treatment of tropical theileriosis caused by Theileria annulata. However, an increase in the rate of buparvaquone treatment failures has been observed in recent years, raising the possibility that resistance to this drug is associated with the selection of T. annulata genotypes bearing mutation(s) in the cytochrome b gene (Cyto b).

Effects of flumethrin and eprinomectin in naturally infected mice with Myocoptes musculinus.

Mite infestations can occur in laboratory mice and cause an undesirable immune system response and adversely affect study results. Myocoptes musculinus is a mite species that can occasionally parasitized in laboratory-housed and breeding mice. In this study, the efficacy of flumethrin and eprinomectin were compared in 30 male Balb/c mice naturally infested with M.

Evaluation of Cases with Suspected Canine Leishmaniasis History: A Five-year Retrospective Study (2016-2021).

Objective: This study aimed to evaluate the polymerase chain reaction (PCR) and immunofluorescence antibody test (IFAT) results of suspected samples with canine leishmaniasis (CanL) that were sent to the Parasitology Department Laboratories of the Veterinary Faculty in Aydın Adnan Menderes University.

Additionally, after the isolation of genomic DNA of 27 blood samples, PCR of these samples was performed using primers that amplify the 145 bp kDNA region of species.

Prevalence of Theileria/Babesia Species in Ruminants in Burdur Province of Turkey.

Purpose: Theileriosis and babesiosis, two tick-borne haemoparasitic diseases (TBHDs) of ruminants, are caused by protozoan parasites of the genus Theileria and Babesia, respectively. Among them, some species are considered to be highly pathogenic causing serious economic losses to livestock holders especially in tropic and subtropic regions. Local and/or general control measures are needed to be applied to reduce economic impact of TBHDs.

Zoonotic visceral leishmaniasis is caused by protozoa of the genus Leishmania. Although dogs are considered to be primary reservoir hosts of Leishmania spp., several mammals, such as foxes, jackals and small rodents may also be hosts of different Leishmania spp.

Molecular and Serological Analysis for Prevalence of Canine Visceral Leishmaniasis in the Muğla Region of Turkey.

Objective: This study aimed to determine the prevalence of canine visceral leishmaniasis by molecular and serological techniques among owned dogs brought to veterinary clinics in the Muğla region of Turkey.

Methods: Blood samples were collected from a total of 131 dogs of different breeds and gender that were brought to veterinary clinics between October 2017 and November 2018 in the Muğla region. These blood samples were analysed using immunofluorescent antibody test (IFAT) and polymerase chain reaction (PCR).

Comparison of protectiveness of recombinant Babesia ovis apical membrane antigen 1 and B. ovis-infected cell line as vaccines against ovine babesiosis.

Babesiosis is a disease complex caused by unicellular Babesia parasites and among them, malignant ovine babesiosis caused by B. ovis has a devastating economical impact on the small ruminant industry. The control of disease is mainly based on chemotherapy and preventing animals from tick infestation and to date no vaccine is available against ovine babesiosis.

High genetic diversity and differentiation of the Babesia ovis population in Turkey.

Babesia ovis is a tick-transmitted protozoan haemoparasite causing ovine babesiosis in sheep and goats leading to considerable economic loss in Turkey and neighbouring countries. There are no vaccines available, therapeutic drugs leave toxic residues in meat and milk, and tick vector control entails environmental risks. A panel of eight mini- and micro-satellite marker loci was developed and applied to study genetic diversity and substructuring of B.

Tick Bites on Humans in Southwestern Region of Turkey: Species Diversity.

Objective: The aim of the present study was to determine tick species found on humans who suffered from tick bite in the Southwestern Anatolia Region, Turkey.

Methods: Between January and October 2007, ticks were collected from people admitted to the city and/or town hospitals with complaints of tick bites in nine different provinces of Turkey. Genus and/or species of the ticks in adult, larva and nymph stages were identified microscopically.

Infection dynamics of Theileria annulata over a disease season following cell line vaccination.

Tropical theileriosis is a tick-borne haemoparasitic disease of cattle caused by the protozoan parasite Theileria annulata. Globally, the economic impact of the disease is immense and enhanced control measures would improve livestock production in endemic regions. Immunisation with a live attenuated vaccine is an effective and widely used control method, however, the repeated use of live vaccines may have an impact on the field parasite population at a genetic level.

Molecular Identification and Clinicopathological Findings of Hepatozoon sp. Infection in a Cat: First Report from Turkey.

Hepatozoon is a genus of protozoa belonging to the phylum Apicomplexa. Ticks are the vectors for the members of this genus. The protozoans infect a wide variety of mammals, birds, reptiles, and amphibians.

Identification of candidate transmission-blocking antigen genes in Theileria annulata and related vector-borne apicomplexan parasites.

Background: Vector-borne apicomplexan parasites are a major cause of mortality and morbidity to humans and livestock globally. The most important disease syndromes caused by these parasites are malaria, babesiosis and theileriosis. Strategies for control often target parasite stages in the mammalian host that cause disease, but this can result in reservoir infections that promote pathogen transmission and generate economic loss.

Background: Tick-borne haemoparasitic diseases (TBHDs), caused by Theileria, Babesia, Anaplasma and Ehrlichia, are common in regions of the world where the distributions of host, pathogen and vector overlap. Many of these diseases threaten livestock production and some also represent a concern to human public health. The primary aim of this study was to determine the prevalence of the above-mentioned pathogens in a large number of blood samples (n = 1979) collected from sheep (n = 1727) and goats (n = 252) in Turkey.
