background: echinococcus granulosus , a zoonotic cestode parasite, causative agent of hydatid cyst is endemic in many parts of the world including the middle east. study on different aspects of this parasite is very important and valuable. however, working with adult worms which their habitat situated in the small intestine of canids, is dangerous and risky. achieving such risky situa­tion need...

The present study was conducted to assess the effects of different feed regimes for nursing knife fish (Notopterus notopterus) larvae up 35 days. Larvae were reared in 50 L tank with Moina, Tubifex worm, and commercial powder substituted culture Feeding worms during found best growth rate survival fish. result obtained when fed 0-5 days 6-20 tubifex 21–35-day weight gain 0.31 g, length 2.36 cm,...

Laboratory-reared Caenorhabditis elegans eat Escherichia coli. A new study demonstrates a strong diet-gene interaction: worms with reduced nhr-114 activity are fertile when fed E. coli K-12 strains but are sterile on E. coli B. Surprisingly, tryptophan supplementation of E. coli B restores worm fertility.

Background: Echinococcosis is a zoonotic parasitic disease caused by the larval stage of Echinococcus granulosus. Several native and recombinant antigens, derived from different stages of E. granulosus life cycle, have been used for vaccine trials. In vitro reared adult worms are good candidates for vaccination as they do not produce fertile egg/s and do not have any risk of contamination for r...

Aspects of the life cycle of the nematomorph Gordius robustus were investigated. Gordius robustus larvae fed to Tenebrio molitor (Coleoptera: Tenebrionidae) readily penetrated and subsequently encysted in the posterior portion of the midgut wall. Parasite development was then arrested in each infected beetle. Upon feeding these cysts to laboratory-reared Gryllus firmus, worm larvae developed to...

the experiment was carried out in a factorial arrangement with the base of randomized complete block design in three repetitions. the first factor consisted of 11 bed for eating worm and the second factor is the different seasons (spring and autumn) respectively. traits was including number of capsules (coconut), the number of adult worms, the number of immature worms, live worms masses (mg), m...

Background: Cystic echinococcosis (CE), also known as echinococcosis/hydatidosis, is one of the most important parasitic diseases in the world. It enhances both humoral and cellular (Th1 and Th2) responses in infected host. Different antigens of the worm may favor the Th1 or Th2 immune responses in CE patients. Objective: To evaluate the humoral and cellular immune responses of Balb/c mice agai...

With a pair of beefed-up forelimbs ready for action, praying mantises look as prepared any prize fighter, but these animals aren't just fighting glory, the stakes are far higher: they're after dinner. Yet, even mighty vulnerable to larger predators, so there will be occasions when it would wise disregard tasty treat avoid ending up on someone else's menu. ‘Most behaviour needs strike balance’, ...

The fall army worm, Spodoptera frugiperda (J E Smith) (Noctuidae; Lepidoptera) is a recently introduced polyphagous pest, poses potential threat to cotton cultivation in India. Therefore, laboratory assays were conducted on different public sector Bt hybrids study the survival and development of pest. results confirmed significantly (p=0.05) higher mortality early larval instars, than later. su...
