Ocular toxocariasis in school children
(2004)Ocular toxocariasis in humans is typically a unilateral disease caused by second?stage larvae of the Toxocara species. Serological evidence of widespread infection in humans provides little information on clinical disease. ... -
On the evolution of claustral colony-founding in ants
(Evolutionary Ecology Ltd, 2003)The dispersal and survival of offspring is a key step in an organism?s life history. In ants, the main strategy used to complete this step is known as independent colony-founding. Here, individual young queens leave their ... -
Patterns of soil-transmitted helminth infection and impact of four-monthly albendazole treatments in preschool children from semi-urban communities in Nigeria: a double-blind placebo-controlled randomised trial.
(2009)BACKGROUND: Children aged between one and five years are particularly vulnerable to disease caused by soil-transmitted helminths (STH). Periodic deworming has been shown to improve growth, micronutrient status (iron and ... -
Predisposition to ascariasis: patterns, mechanisms and implications
(2009)Ascaris lumbricoides, the human roundworm, is a remarkably infectious and persistent parasite. It is a member of the soil-transmitted helminths or geohelminths and infects in the order of 1472 million people worldwide. ... -
Procollagen Type I amino-terminal propeptide : pediatric reference data and relationship with procollagen type I carboxyl-terminal propeptide
(American Association for Clinical Chemistry, 2004)Type I collagen is the predominant collagen in bone and soft tissue. The rate of synthesis of type I collagen can be assessed by measuring plasma concentrations of the C-terminal (PICP) and N-terminal (PINP) propeptides ... -
Queen-controlled sex ratios and worker-reproduction in the bumble bee Bombus hypnorum, as revealed by microsatellites
(Blackwell, 2003)Social insect colonies provide model systems for the examination of conflicts among parties with different genetic interests. As such, they have provided the best tests of inclusive fitness theory. However, much remains ... -
Soil-transmitted helminth infections in Nigerian children aged 0-25 months
(2009)The objective of this cross-sectional study was to determine the prevalence and intensity of soil-transmitted helminths (STHs) in children aged 0?25 months and to identify the associated risk factors for Ascaris lumbricoides ... -
Strong context-dependent virulence in a host-parasite system: reconciling genetic evidence with theory
(Blackwell, 2003)1. Parasites can have dramatic effects on the ecology of their hosts. Such strong host-parasite interactions are the result of either parasites with generally high virulence, or generally benign parasites that nevertheless ... -
Toxocara in the mouse : A model for parasite-altered host behaviour ?
(2001)The objective of this paper is to critically evaluate the significance of parasite-altered host behaviour in the Toxocara mouse model particularly in the light of the Manipulation Hypothesis. Murine behaviours were examined ... -
Two domains of the human bZIP transcription factor TCF11 are necessary for transactivation

Utilisation of brown trout by Acanthocephalus clavula (Acanthocephala) in brown trout (Salmo trutta) in an Irish lake: is this evidence of a host shift?
(2004)The population biology of the fish acanthocephalan Acanthocephalus clavula was described from 161 wild brown trout, Salmo trutta sampled over a two-year period in Clogher Lake in the west of Ireland. Overall prevalence of ...
