Body composition and fatty acid profile of the body tissue of Caspian kutum (Rutilus frisii kutum) fish larvae were determined from fertilized egg to 50 days post hatching (dph). Feeding with rotifer started from day 3 to day 7 thereafter they were fed with dry food until the end of the experiment. The changes observed in lipid content and the decrease in lipid levels during larval ontogeny ref...

  Khark and Kharko Islands are located at far northern point of fringing coral reefs in the Iranian coast of the Persian Gulf. These coralline are the habitats of the wildlife refuge with total area of 2400ha and located in the territory of Bushehr province. The present study was carried out from July 2006 to June 2007 over 12 stations. Sampling was conducted obliquely from bottom using Bongo-n...

The aim of this study was to evaluate the effect of environmentally realistic egg loadings of the polychlorinated biphenyl Aroclor 1254 on the subsequent growth and behavioural survival skills of Atlantic croaker Micropogonias undulatus larvae. Adult fish were given a dietary administration of 0 (control) or 0.4 (dosed) mg Aroclor 1254 kg–1 fish d–1 for 2 wk during the final stages of gonadal r...

Efficacy of albendazole against early and late stage of Trichinella spiralis infection in mice was determined. To determine the efficacy of albendazole against the early stage (enteral phase) of trichinosis, mice experimentally infected with T. spiralis were treated with albendazole 20 mg/kg at 7 days post infection for 15 days. Larvae were recovered from the infected mice 7 days after the trea...

Ascaris lumbricoides remains the most common endoparasite in humans, yet there is still very little information available about the immunological principles of protection, especially those directed against larval stages. Due to the natural host-parasite relationship, pigs infected with A. suum make an excellent model to study the mechanisms of protection against this nematode. In pigs, a self-c...

To elucidate the relationship between diapause and cold hardiness in the oriental corn borer, Ostrinia furnacalis, the levels of various substances, cold hardiness and respiration were measured in diapausing and post-diapausing overwintering larvae. Under field conditions, diapause terminated between November and January, although O(2) consumption, measured at 20 degrees C in the laboratory, re...

OBJECTIVES Epidermicin is a novel antimicrobial peptide that has potent activity against Gram-positive pathogens, including methicillin-resistant Staphylococcus aureus, and it may have potential for use in therapy for infections caused by these bacteria, though in vivo efficacy needs to be demonstrated. Galleria mellonella larvae have recently been introduced as an alternative in vivo model to ...

A preliminary study to characterize filamentous bacteria, whose presence is related to high mortality of Litopenaeus vannamei larvae cultured in Santa Catarina State, Brazil, is reported. The extract of infected larvae was diluted in different concentrations, cultured in marine agar (Difco, Marine Agar 2216) and incubated at 30 degrees C for 48 hours. The biochemical characterization included h...

The recent appearance and invasion of feral oysters (Crassostrea gigas) along the northern European Atlantic coast, underscores the necessity to investigate the relationship between environmental variables, reproductive physiology, larval development and recruitment. We studied these relationships at both high (HT) and intermediate (IT) - turbidity sites, through historical data on water temper...
