Although there is evidence of high seroprevalence of antibodies to Babesia spp. in dogs in central Namibia, clinical babesiosis is rarely diagnosed. Rhipicephalus sanguineus sensu lato, the vector of Babesia vogeli, is common in Namibia while Haemaphysalis elliptica, the vector of the highly virulent but morphologically indistinguishable Babesia rossi, has rarely been recorded, mainly in northe...

Co-infection with Borrelia species and Anaplasma phagocytophilum or Babesia spp. was assessed in a retrospective study of tick-exposed individuals from southeastern Poland. The co-infection rate of these pathogens was found to be rather low (Borrelia spp./Anaplasma phagocytophilum--4.2%, 1/24; Borrelia spp./Babesia spp.--4.2%, 1/24). However, due to the increased prevalence of Borrelia spp. in ...

A study on the presence of Babesia in humans was performed in Puerto Berr o (Latitude 6.50deg. Longitude: -74.38deg. River: Magdalena. Area: 74.410km , Colombia-South America). Indirect immunofluorescence, thin and thick blood smears were used to study 194 individuals. Patients were grouped according to their risk-factors for Babesia infection: (group 1) individuals with fever, chills, sweating...

The haemoprotozoan Babesia canis has been recognized in Australia for many years, and a second, smaller species has recently been discovered. Amplification and sequencing of a partial region of the 18S small subunit ribosomal RNA (rRNA) gene enabled detection and characterization of the large and small canine babesiae of Australia for the first time. Isolates from northern Australia were geneti...

Serum and DNA from blood samples collected from Vietnamese yellow cattle (n=101) and cattle imported from Thailand (n=54) at a Vietnamese slaughter house were screened for Babesia bovis and Babesia bigemina infections by enzyme-linked immunosorbent assay (ELISA) and PCR. The positive rates determined by ELISA (B. bovis and B. bigemina) or PCR (B. bigemina) in the Vietnamese cattle were signific...

We report the complete genome sequence of Mycoplasma ovis strain Michigan. Its single circular chromosome has 702,511 bp and contains 2 copies of the 16S rRNA gene, one corresponding to M. ovis and the other to "Candidatus Mycoplasma haemovis." All housekeeping genes and the 5S-23S rRNA genes are present in single copies.

In this study blood samples were collected from 193 goats in north and northeastern Iran with the aim to develop a PCR-RFLP assay, as a specific and sensitive diagnostic tool enabling direct and concurrent identification of two Anaplasma species (A. ovis, A. marginale) in goats. A polymerase chain reaction (PCR) for amplification of a fragment of the major surface protein 4 (msp4) gene from A....

Infectious bovine keratoconjunctivitis (IBK) is a highly contagious ocular disease that affects cattle of all ages and that occurs worldwide. Piliated hemolytic Moraxella bovis is recognized as the etiologic agent of IBK. According to data from the Nebraska Veterinary Diagnostic Laboratory System, however, Moraxella (Branhamella) ovis has been isolated with increasing frequency from cattle affe...

Recent epidemiological observations from field studies indicated that sheep selected for resistance to digestive nematodes were more infected than susceptible ones with the nasal bot fly, Oestrus ovis. The present study was undertaken to verify these informations and to explore the possible associated mechanisms. After a whole grazing season and an anthelmintic drench, two groups of 6 rams belo...

In the present study, to contribute to the understanding of the evolutionary history of sheep, the mitochondrial (mt) DNA polymorphisms occurring in modern Turkish native domestic (n = 628), modern wild (Ovis gmelinii anatolica) (n = 30) and ancient domestic sheep from Oylum Höyük in Kilis (n = 33) were examined comparatively with the accumulated data in the literature. The lengths (75 bp/76 bp...
