The infective larvae of Nematospiroides dubius were exposed to various levels (0-30 krad) of gamma irradiation by means of a Cobalt 60 source. Groups of mice were infected with these larvae and autopsied 5 weeks later for worm counts. It was found that male worms were more susceptible to irradiation than female worms. In both instances, however, the survival curve on a semi logarithmic plot was...

The aim of this study was to determine the insecticide potential essential oils (EOs) thyme (Thymus vulgaris; Lamiaceae) and ginger (Zingiber officinale; Zingiberaceae) control cotton leaf worm (Spodoptera littoralis; Lepidoptera: Noctuidae) under laboratory conditions. Generally, there a positive correlation between magnitude above toxic effects concentrations all EOs. Ginger oil (GEO) showed ...

BEHNKE J. M. 1975. Immune expulsion of the nematode Aspiculuris fetraptera from mice given primary and challenge infections. International Journal for Parasitology 5: 511-515. The distribution of larval Aspiculuris tetraptera was studied in 4-week-old male and female CFLP mice. Whereas on days lo-12 the larvae were entirely confined to the anterior third of the colon, by day 14 larvae could be ...

Insects have been proposed as a high-quality, efficient and sustainable dietary protein source. The present study evaluated the protein quality of a selection of insect species. Insect substrates were housefly pupae, adult house cricket, yellow mealworm larvae, lesser mealworm larvae, Morio worm larvae, black soldier fly larvae and pupae, six spot roach, death's head cockroach and Argentinean c...

Organisms are attacked by different natural enemies present in their habitat. While enemies such as parasitoids and predators will kill their hosts/preys when they successfully attack them, enemies such as micropredators will not entirely consume their prey. However, they can still have important consequences on the performance and ecology of the prey, such as reduced growth, increased emigrati...

Background Urinary myiasis is a form of myiasis caused mainly by larvae of Fannia scalaris, Musca, Sarcophaga, Lucilia, Wohlfahrtia, Calliphora, and rarely by Eristalis and Clogmia albipunctata. Methods This report presents a case of female patient complaining of dysuria and frequency of micturition associated with intermittent passage of small, motile, dark-colored worm-like organisms in uri...

Nigeria reported highest incidence of dracunculiasis in the world 1991 (WHO 1991). Ebonyi, a small state south-eastern part country was rated most endemic with total 3,370 cases 1996 alone (Global 2000 & Ojodu 2001). In 2005, World Health Organisation proclaimed that disease eradicated from Ebonyi and indeed, Nigeria, declared guinea worm free. This study examined bionomics Cyclops sampled ...

Burkholderia is an important bacterial genus with a complex taxonomy that contains species of both ecological and pathogenic importance, including nine closely related species collectively termed the Burkholderia cepacia complex (BCC). In order to more thoroughly investigate the virulence of this bacterial complex of microorganisms, alternative infection models would be useful. To this end, we ...

Angiostrongylus cantonensis is the major cause of eosinophilic meningoencephalitis cases in Taiwan. Mice were orally infected with 35 infective larvae. One group of mice were given a single dose of mebendazole (20 mg/kg of body weight) per os at various times and examined at 14 days postinfection (dpi) for worm recovery rate and pathological studies. A 94 to 97% reduction in worm recovery was o...

To the Editor: The commentary by Das regarding the paper of Summers et al on the use of the pig pathogen, Trichuris suis, as a treatment of inflammatory bowel disease raises some important questions. We have been aware of this treatment since 1999, when at an AGA meeting, a poster prompted one of us to question the safety of it. Summers et al have repeatedly spoken of T. suis as noninvasive. In...
