The relationship between three intensity levels of Toxocara canis larvae in the brain and effects on exploration, anxiety, learning and memory in the murine host
(2001)Outbred LACA mice were administered low (100 ova), medium (1000 ova), high (3000 ova) and trickle (4?250 ova) doses of Toxocara canis ova and the effect of infection was examined with respect to the number of larvae recovered ... -
The public health importance of Ascaris lumbricoides
(2000)Numerous studies have shown that anthelminthic treatment can be effective in improving growth rates when given to malnourished children with ascariasis. Recent investigations have also indicated that Ascaris infections can ... -
The public health significance of Trichuris trichiura
(2000)An estimated 1049 million persons harbour T. trichiura, including 114 million preschool-age children and 233 million school-age children. The prevalence of T. trichiura is high and may reach 95% in children in many parts ... -
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 ... -
The influence of inoculum size and time post-infection on the number and position of Toxocara canis larvae recovered from the brains of outbred CD1 mice
(2001)Outbred CD1 mice were administered doses of 1000 and 3000 Toxocara canis eggs and postmortem took place on days 7, 42 and 120 post-infection. Mice were killed by cervical dislocation and brains were sagitally bisected and ... -
Serum crosslaps: pediatric reference intervals from birth to 19 years of age
(American Association for Clinical Chemistry, 2002)During childhood growth, bone undergoes extensive modeling involving separate osteoblastic and osteoclastic processes. Markers of bone formation and resorption circulate at higher concentrations in children than in adults, ... -
Comparison of the macroparasite communities of stocked and wild trout (Salmo trutta) from the West of Ireland
(2002)The aim of the present study was to compare the helminth infra and component communities of wild and stocked brown trout in Lough Feeagh, in the west of Ireland, and also to examine the establishment and development of ... -
Interspecific interactions between Acanthocephala in the intestine of brown trout : are they more frequent in Ireland?
(2003)The aim of this paper was to test the hypothesis that when the 2 species of Acanthocephalan Pomphorhynchus laevis and Acanthocephalus clavula are found concurrently within the intestine of brown trout under field conditions, ... -
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. ... -
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 ... -
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 ... -
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. ... -
The development of a mouse model to explore resistance and susceptibility to early Ascaris suum infection
(2006)Ascaris suum and Ascaris lumbricoides exhibit an over-dispersed frequency distribution in their host populations in both the adult and larval stages. The impact of host factors on this observed distribution is still poorly ... -
The migration of Ascaris suum larvae, and the associated pulmonary inflammatory response in susceptible C57BL/6j and resistant CBA/Ca mice
(2007)Ascariasis is an important infection in humans (Ascaris lumbricoides) and pigs (Ascaris suum) and individuals appear to be predisposed to either heavy or light worm burdens. These extremes of susceptibility and resistance ... -
A murine model for cerebral toxocariasis: characterisation of host susceptibility and behaviour.
(2006)Toxocara canis, the parasitic roundworm of dogs, can infect a number of paratenic hosts, such as mice and humans, due to the widespread dissemination of its ova in the environment. In these paratenic hosts, larvae have ... -
Dose-dependent impact of larval Ascaris suum on host body weight in the mouse model
(2009)Ascaris lumbricoides and Ascaris suum are important helminth parasites of humans and pigs, respectively. Although it is now well established that the presence of mature adult worms in the host intestine contributes to ... -
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 ... -
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 ... -
Identification of Mechanosensitive Genes during Embryonic Bone Formation.
(2008)Although it is known that mechanical forces are needed for normal bone development, the current understanding of how biophysical stimuli are interpreted by and integrated with genetic regulatory mechanisms is limited. ... -
Impacts of inbreeding on bumblebee colony fitness under field conditions
(BioMed Central, 2009)BACKGROUND: Inbreeding and the loss of genetic diversity are known to be significant threats to small, isolated populations. Hymenoptera represent a special case regarding the impact of inbreeding. Haplodiploidy may permit ...
