Red deer (Cervus elaphus) were introduced in southern Latin America about a century ago and characteristics of the invasion raise concerns over their epidemiological role for various diseases. We report on the possible occurrence of Taenia ovis krabbei established in a sylvatic cycle in Patagonia. Hook characters, size, appearance, and location of a cysticercus from a wild red deer are consiste...

BACKGROUND Hemotropic mycoplasmas (hemoplasmas) are emerging zoonotic pathogens with a worldwide distribution that can cause mild to severe hemolytic anemia, icterus, ill-thrift, infertility, and poor weight gain. However, understanding of the molecular epidemiology of hemoplasmas (Mycoplasma ovis and 'Candidatus Mycoplasma haemovis') is limited in sheep and goats, and the hemoplasma strain/spe...

The present study assesses the efficacy of SVANOVIR Theileria annulata-Ab, the first commercial ELISA kit for the diagnosis of Theileria annulata infection in cattle based on a recombinant protein known as T. annulata surface protein (TaSp). As a reference test, a polymerase chain reaction (PCR) assay depending on T. annulata merozoite surface antigen (Tams-1) was applied. A total of 468 blood ...

Cross-neutralization studies showed that 3 different isolates of herpesvirus ovis from cell cultures derived from the lungs of sheep suffering from jaagsiekte were not only identical but were also related to similar isolate made in Scotland. No relationship, however, could be established between herpesvirus ovis and common bovine or equine herpesviruses. Antibodies to herpesvirus ovis were pres...

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....

BACKGROUND In 2012-2013, an investigation was carried out in the Viterbo province, Lazio region, on ticks and tick-borne Apicomplexan protozoa of the Babesia and Theileria genera. This followed the reporting of high density of ticks by soldiers operating in a military shooting range, and the signaling by owners and local veterinary authorities of several cases of babesiosis among cattle. METH...

Several facets of spliceosomal intron in apicomplexans remain mysterious. First, intron numbers vary across species by 2 orders of magnitude, indicating massive intron loss and/or gain. Second, previous studies have shown very different evolutionary patterns over different timescales, with 100-fold higher rates of intron loss/gain between genera than within genera. Third, the timing and dynamic...

As part of a larger survey to map the geographical distribution of Babesia and Theileria parasites in the southern African rhinoceros population, white rhinoceroses were sampled during routine immobilisations in the Kruger National Park. Polymerase chain reaction (PCR) and reverse line blot (RLB) hybridisation assays were used to screen for the presence of piroplasms and complete blood counts w...

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...
