molecular detection of tick-borne rickettsial and protozoan pathogens in domestic dogs from turkey.canine tick-borne parasites have emerged in recent years, showing a wider geographic distribution and increased global prevalence. in addition to their veterinary importance, domestic dogs play an important role in the transmission cycles of some agents by acting as reservoirs and sentinels. this study investigated babesia, theileria, anaplasma, and ehrlichia species in asymptomatic dogs in ten provinces of turkey.201525889911
screening of bat faeces for arthropod-borne apicomplexan protozoa: babesia canis and besnoitia besnoiti-like sequences from chiroptera.bats are among the most eco-epidemiologically important mammals, owing to their presence in human settlements and animal keeping facilities. roosting of bats in buildings may bring pathogens of veterinary-medical importance into the environment of domestic animals and humans. in this context bats have long been studied as carriers of various pathogen groups. however, despite their close association with arthropods (both in their food and as their ectoparasites), only a few molecular surveys have ...201526315069
novel foci of dermacentor reticulatus ticks infected with babesia canis and babesia caballi in the netherlands and in belgium.autochthonous populations of dermacentor reticulatus ticks in the netherlands were discovered after fatal cases of babesiosis occurred in resident dogs in 2004. the presence of d. reticulatus in the netherlands has also linked with the emergence of piroplasmosis in the resident horse population. the aim of this study was to put together results of continued surveillance of field sites and hosts for this tick in the netherlands and also in belgium and determine their infection status for babesia ...201525889392

development of loop-mediated isothermal amplification (lamp) for detection of babesia gibsoni infection in dogs.diagnosis of canine babesiosis, caused by babesia gibsoni is difficult, especially in chronically infected dogs. a loop mediated isothermal amplification (lamp) assay was developed and standardized by using four oligonucleotide primers targeting the hypervariable region of 18s rrna gene (genbank acc. no. kc461261). the primers specifically amplified b. gibsoni dna, while no amplification was detected with dna from non-infected dogs as well as from dogs infected with babesia canis vogeli, hepatoz ...201525749021
distribution patterns of babesia gibsoni infection in hunting dogs from nine japanese islands.canine babesiosis constitutes a major global veterinary medical problem caused by tick-borne hemoparasites babesia gibsoni and babesia canis. babesia gibsoni induces more severe clinical signs and is mainly transmitted by the ixodid haemaphysalis longicornis. in japan, b. gibsoni is primarily found in the western districts, with few records in the eastern parts. the aim of the current investigation was to evaluate distribution patterns of b. gibsoni infection in 9 japanese islands and peninsulas ...201525419881
hyperaldosteronism and its association with hypotension and azotaemia in canine babesiosis.the previous work on canine babesiosis revealed hypokalaemia and increased fractional excretion of potassium in infected dogs suggesting a role for aldosterone in the loss of potassium via the kidneys in affected dogs. moreover, hypotension, which is one of the complications of canine babesiosis leading to renal failure, may induce secondary hyperaldosteronism.201525347616
first molecular identification of babesia gibsoni in dogs from slovakia, central europe.canine babesiosis is a severe and potentially life threatening infection. in europe, babesia canis is considered to be the most common species responsible for the disease. we report two cases of babesiosis caused by babesia gibsoni. the polymerase chain reaction, restriction fragment length polymorphism analysis and further sequencing of 18s rrna gene fragments from blood samples of both dogs revealed the identity of isolates with b. gibsoni genotypes from other dogs worldwide. this species was ...201626304014
