it is well established that reproduction is sensitive to the state of energy reserves, and that there is a balance between energy homeostasis and fertility. in this view, this study examined the effects of different diets on growth and reproductive performance of fresh water angelfish. twenty four pairs of angelfish (weighing 3.58 ± 0.24 g) were fed with four types of diets including live earth...

We report a statistical study to discover transcriptome similarity of developmental stages from D. melanogaster and C. elegans using modENCODE RNA-seq data. We focus on "stage-associated genes" that capture specific transcriptional activities in each stage and use them to map pairwise stages within and between the two species by a hypergeometric test. Within each species, temporally adjacent st...

INTRODUCTION: The activity of garlic oil extract against Schistosoma japonicum cercariae was evaluated. METHODS: The in vitro and in vivo cercaricidal activities against S. japonicum larvae were determined. RESULTS: Exposure to ≥ 10-6 (v/v) garlic emulsions for 30 min led to 100% cercariae mortality; pre-exposure treatment with ≥ 10-4 (v/v) garlic emulsions showed 100% preventive efficacy ...

BACKGROUND Strongyloidiasis is a truly neglected tropical disease, but its public health significance is far from being negligible. At present, only a few drugs are available for the treatment and control of strongyloidiasis. METHODOLOGY/PRINCIPAL FINDINGS We investigated the activity of tribendimidine against third-stage larvae (L(3)) of Strongyloides ratti in vitro and against juvenile and ...

This study investigated why the susceptible or resistance phenotype to the nematode Heligmosomoides polygyrus was lost when susceptible (C57BL/6) and resistant (Balb/c) strains of mice were housed together in indoor arenas with continuous transmission of the parasite larvae present in peat trays (Scott, 1991). First, both strains expressed their normal phenotype when given a controlled challeng...

Regular worm counts were done post-mortem on sheep that had grazed on Kikuyu pastures at the Elsenburg Research Station near Stellenbosch, a winter rainfall region. Major species were Trichostrongylus colubriformis, Trichostrongylus axei, while Ostertagia circumcincta was usually present in large numbers. Minor species were Haemonchus contortus, Nematodirus spathiger, Dictyocaulus filaria, Oeso...

Studies on common antigenicities were carried out by using rabbit sera immunized with Angiostrongylus cantonensis adult worms or the third stage larvae and antigens of various species of snails and vice versa by the immunoblotting technique. The results obtained are summarized as follows: (1) Common antigenicities between A. cantonensis adult worms and snails susceptible to A. cantonensis were ...

NEVILL, E. M., 1975 Preliminary report on the transmission of Parafi/aria bovicola in South Africa. Onderstepoort J. vet. Res. 42 (1), 41-48 (1975) The filarial worm Parafi/aria bovico/a causes streaks of blood on the skins of live cattle and slimy bruise-like lesions on the subcutaneous surfaces of their carcases. To determine the vectors of this worm a field survey was conducted in November 1...

introduction ophthalmomyiasis is a rare disorder that is caused by invasion of dipterous larvae to necrotic tissues. case presentation an 80-year-old woman with invasive basal cell carcinoma (bcc) presented anabnormal growth of worm in her eye. she had ophthalmomyiasis caused by lucilia sericata larva in here nucleated eye. l. sericata is common all over the temperate and tropical regions, main...

Canthariasis is a human/ animal infestation by larval stages of coleopteran insects - the beetles. This study reports rare case gastrointestinal canthariasis caused Alphitobiusdiaperinus. A six-year-old boy presented with complaints pain abdomen associated non-bilious, non-blood-stained vomiting for 15 days and history passage worm-like creatures via stools occasionally in vomitus. All investig...
