Identification of Theileria uilenbergi immunodominant protein for development of an indirect ELISA for diagnosis of ovine theileriosis.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Theileriosis of small ruminants in the northwest of China is a protozoan disease that restricts the development of the livestock industry. The disease is caused by infection with Theileria uilenbergi and Theilerialuwenshuni, both of which are transmitted by ixodid Heamaphysalis ticks. The development of serological tools as a means of integrated control of the disease is an urgent and important requirement. Here we describe the identification and partial recombinant expression of a T.uilenbergi immunodominant protein (TuIP), which was identified by immunoscreening of a merozoite cDNA library. Using the recombinant TuIP...

Estimating the sensitivity and specificity of Kato-Katz stool examination technique for detection of hookworms, Ascaris lumbricoides and Trichuris trichiura infections in humans in the absence of a 'gold standard'Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The accuracy of the Kato-Katz technique in identifying individuals with soil-transmitted helminth (STH) infections is limited by day-to-day variation in helminth egg excretion, confusion with other parasites and the laboratory technicians' experience. We aimed to estimate the sensitivity and specificity of the Kato-Katz technique to detect infection with Ascaris lumbricoides, hookworm and Trichuris trichiura using a Bayesian approach in the absence of a 'gold standard'. Data were obtained from a longitudinal study conducted between January 2004 and December 2005 in Samar Province, the Philippines. Each participant prov...

Malaria vaccines - how and when to proceed?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In the field of malaria vaccines, there are many barriers to moving lead candidates from the bench into developmental programmes before clinical testing. Many of the same challenges are to be found in the field of vaccines for other infectious diseases. Here, we briefly outline the process of pre-clinical development to help identify ways to support the translation of laboratory-based information into viable vaccine candidates.

The Association of Adult Onchocerca volvulus with Lymphatic Vessels.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Immunocytochemical examination of onchocercal nodule tissues containing adult Onchocerca volvulus using immuno-markers for blood and lymphatic vessels (Factor VIII, D2-40, podoplanin, Prox-1 and Lyve1) shows a distinct pattern of distribution of these vessels within nodules. Blood vessels were commonly seen associated with organized lymphoid cellular aggregates in the both the outer and inner areas of the nodules. In contrast, the majority of the lymphatic vessel components were present in the central zones in close apposition to the adult parasites, or associated with microfilariae in the outer areas of the nodule. Th...

The dynamics of mutations associated with anti-malarial drug resistance in Plasmodium falciparum.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The evolution of resistance in Plasmodium falciparum against safe and affordable drugs such as chloroquine (CQ) and sulfadoxine-pyrimethamine (SP) is a major global health threat. Investigating the dynamics of resistance against these antimalarial drugs will lead to approaches for addressing the problem of resistance in malarial parasites that are solidly based in evolutionary genetics and population biology. In this article, we discuss current developments in population biology modeling and evolutionary genetics. Despite great advancements achieved in the past decade, understanding the complex dynamics of mutations co...

Toxoplasmosis: a history of clinical observations.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
It has been 100 years since Toxoplasma gondii was initially described in Tunis by Nicolle and Manceaux (1908) in the tissues of the gundi (Ctenodoactylus gundi) and in Brazil by Splendore (1908) in the tissues of a rabbit. Toxoplasma gondii is a ubiquitous, Apicomplexan parasite of warm-blooded animals that can cause several clinical syndromes including encephalitis, chorioretinitis, congenital infection and neonatal mortality. Fifteen years after the description of T. gondii by Nicolle and Manceaux a fatal case of toxoplasmosis in a child was reported by Janků. In 1939 Wolf, Cowen and Paige were the first to con...

Differential gene expression in hypobiosis-induced and non-induced third-stage larvae of the bovine lungworm Dictyocaulus viviparus.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Hypobiosis is of particular importance in overwintering of the bovine lungworm Dictyocaulus viviparus. However, in parasitic nematodes there is no information available on the genetic mechanisms of hypobiosis. Suppression subtractive hybridisation was performed to identify upregulated transcripts of hypobiosis-induced and non-induced third-stage D. viviparus larvae, respectively. Subtracted libraries containing 105 clones of the hypobiosis-induced and 104 clones of the non-induced larvae were generated. By differential screening and Southern dot blot, 26 clones of the hypobiosis-induced and 22 clones of the non-induced...

The little-known Dipteropeltis hirundo Calman, 1912 (Crustacea, Branchiura): SEM investigations of paratype material in light of recent phylogenetic analyses.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The Branchiura are fish ectoparasites which include the well-known and very commonly found genus Argulus. But the Branchiura also contains the monotypic genus Dipteropeltis, about which only very little is known. In this investigation of two female paratype specimens we describe for the first time the external morphology of Dipteropeltis based on Scanning Electron Microscopy. We show that Dipteropeltis has a pre-oral spine, unique suction disc support structures, an Argulus-like mouth cone and second maxillae with a combination of features seen in both Argulus and Chonopeltis. This data is compared with data from the t...

Lack of resistance against the tick Ixodes ricinus in two related passerine bird species.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Although many wild bird species may act as reservoir hosts for tick-transmitted diseases and/or support long distance dispersal of infected ticks, to date no research has been done on the extent to which songbirds may acquire resistance to ixodid ticks. Here we investigate whether two passerine species belonging to the family Paridae, the the blue tit (Cyanistes caeruleus) and the great tit (Parus major), are able to acquire resistance after repeated infestations with Ixodes ricinus nymphs. As blue tits are less frequently exposed to I. ricinus in the wild than great tits, we expected I. ricinus to be less adapted towa...

Balamuthia mandrillaris: Role of galactose in encystment and identification of potential inhibitory targets.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In this study, we examined the effects of exogenous sugars on B. mandrillaris encystment. The findings revealed that free exogenous galactose, but not other sugars, enhanced parasite differentiation into cysts, and apparently a galactose-binding protein is involved in B. mandrillaris encystment. Cytoskeletal re-arrangements and phosphatidylinositol 3-kinase (PI3K)-mediated pathways are involved in B. mandrillaris encystment based on inhibitor studies. Dual functionality of galactose-binding protein in B. mandrillaris pathogenesis and encystment is discussed further. PMID: 19766634 [PubMed - as supplied by publisher] (S...

Cucullanus maldivensis n. sp. (Nematoda: Cucullanidae) and some other adult nematodes from marine fishes off the Maldive Islands.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Marine fishes were collected from off the Maldive Islands in March, 2005. From amongst the material collected, the nematode Cucullanus maldivensis n. sp. is described from the intestine of a lutjanid fish, the black and white snapper Macolor niger (Forsskål). This species is morphologically and biometrically most similar to C. bourdini Petter & Le Bel, 1992, differing from it principally in the protruding vulval lips, the location of the first pair of pre-anal papillae, the absence of an elevated cloacal region, and having distinctly larger eggs (51-57 x 33-36 mum). Additionally, adult females of the nematodes...

Does resistance to filarial reinfections become leaky over time?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Strategies for the control of human parasitic diseases such as onchocerciasis and lymphatic filariasis require an understanding of how the parasite successfully infects and persists in humans. Despite the fact that the vast majority of infective larvae are eliminated after infection, this 'protection' is far from being an all-or-nothing response. The hypothesis presented here, which is based on epidemiological observations, suggests that the resistance against filarial parasites includes a time-dependent component, probably caused by an early immune response with short-term memory. Validating this hypothesis requires e...
