Halofuginone lactate, given once orally at a dosage rate of 1,2 mg/kg body mass on the 1st, 3rd or 5th days of fever, resulted in the recovery of only 1 out of 5 splenectomized cattle. Three splenectomized animals, treated on the 1st as well as the 4th day of fever, recovered and were then carriers. Six untreated controls all died. The potential value of a chemotherapeutic agent for Theileria p...

BACKGROUND Bovine theileriosis results from infection with obligate intracellular protozoa of the genus Theileria. The phylogenetic relationships between two isolates of Theileria annulata, and 36 Theileria spp., as well as 6 outgroup including Babesia spp. and coccidian protozoa were analyzed using the 18S rRNA gene sequence. METHODS The target DNA segment was amplified by PCR. The PCR produ...

A major problem in evaluating biological invasions is the lack of information on failed non-native species introductions, with invasiveness determined purely on establishment successes. This is the case of topmouth gudgeon Pseudorasbora parva, an Asiatic cyprinid fish that now occurs throughout most of Europe and is said to be highly invasive. Although the species has established itself in many...

East Coast fever is a lymphoproliferative disease caused by the tick-borne protozoan parasite Theileria parva. The sporozoite stage of this parasite, harboured and released from the salivary glands of the tick Rhipicephalus appendiculatus during feeding, invades and establishes infection in bovine lymphocytes. Blocking this initial stage of invasion presents a promising vaccine strategy for con...

Turneriella parva Levett et al. 2005 is the only species of the genus Turneriella which was established as a result of the reclassification of Leptospira parva Hovind-Hougen et al. 1982. Together with Leptonema and Leptospira, Turneriella constitutes the family Leptospiraceae, within the order Spirochaetales. Here we describe the features of this free-living aerobic spirochete together with the...

We have developed two loop-mediated isothermal amplification (LAMP) assays for the detection of Theileria parva, the causative agent of East Coast fever (ECF), an economically important cattle disease in eastern, central and southern Africa. These assays target the polymorphic immunodominant molecule (PIM) and p150 LAMP genes. The primer set for each gene target consists of six primers, and eac...

An infection and treatment protocol is used to vaccinate cattle against Theileria parva infection. Due to incomplete cross-protection between different parasite isolates, a mixture of three isolates, termed the Muguga cocktail, is used for vaccination. While vaccination of cattle in some regions provides high levels of protection, some animals are not protected against challenge with buffalo-de...

Theileria parasites invade and transform bovine leukocytes causing either East Coast fever (T. parva), or tropical theileriosis (T. annulata). Susceptible animals usually die within weeks of infection, but indigenous infected cattle show markedly reduced pathology, suggesting that host genetic factors may cause disease susceptibility. Attenuated live vaccines are widely used to control tropical...

Many individual hosts are infected with multiple parasite species, and this may increase or decrease the pathogenicity of the infections. This phenomenon is termed heterologous reactivity and is potentially an important determinant of both patterns of morbidity and mortality and of the impact of disease control measures at the population level. Using infections with Theileria parva (a tick-born...
