Arrested development of abomasal trichostrongylid nematodes was studied in 30 permanent grazing lambs on a large farm in the North-East of Algeria. The steppe climate has cold winters and hot and dry summers. The lambs were monitored monthly for gastrointestinal nematodes using nematode faecal egg counts, from February 2008 to February 2009. Every 2 months, two of the original 30 permanent lamb...

Four trials were conducted to determine the effect of different levels of nodular worm (Oesophagostomum spp.) infection on the performance of growing-finishing swine and on digestion and absorption of nutrients by the growing pig. In each of two growing-finishing trials, 48 crossbred pigs (average body weight 26.6 kg in trial 1 and 24.4 kg in trial 2) were individually housed and given a single...

We describe a 61-year-old man who developed a mild gastrointestinal discomforts including diarrhea associated with feces containing many larvae similar to rhabditiform larvae of Strongyloides stercoralis diagnosed finally as Diploscapter coronata, a free-living nematode. This case is unusual infection in human and there are a few reports of this worm as a real parasite. Microscopically, Diplosc...

Earhead worm Autoba silicula (Swinhoe, 1897) (Lepidoptera: Erebidae) is recorded for the first time in India on maize. Larvae were found feeding maturing grains and silk, fully fed matured larvae pupates under a dome shaped or elongated galleries made of silk inside cob. Roving survey conducted during 2019 2020 an average 0.40 0.45 per plant, respectively, which below economic threshold. In pre...

background: haemonchus contortus causes severe economic losses in small ru-minants, so this study was conducted to study the uv effect on h. contortus larvae and its protective effect. methods: sixteen male goats were divided into 5 groups, control infected, con-trol uninfected and uv 30minutes exposure; uv 60minutes exposure and uv booster 60minutes exposure. the uv groups were exposed to uv i...

that the clinical isolate and the larvae from the Pacifi c cod were identifi ed as P. azarasi, 1 of 2 species found in water near Japan. Adult worms live in the intestines of seals and sea lions, and infective larvae live in the tissues of various marine fi sh, including cod, pollack, and smelt (1). In Japan, most patients infected with Pseudoterranova spp. have acute or subacute abdominal pain...

AIM To investigate the ultrastructural features of the newly hatched larvae of Strongyloides stercoralis in human duodenal mucosa. METHODS Duodenal biopsies from an AIDS patient were studied by transmission electron microscopy to investigate morphology, location, and host-worm relations of newly hatched larvae. RESULTS Newly hatched larvae were found in the Lieberkuhn crypts within the tunn...

The present study explored the embryonic and larval development of an endangered fish species Nandus nandus and resolved larval growth performances with the dietary supplementation of different types of lipids. Fertilized eggs were collected from fiber glass tanks immediately after spontaneous spawning of N. nandus, which were fed with a 1% phospholipid (squid meal) supplemented diet for 3 mont...

Infective larvae (L3) of a strain of benzimidazole-resistant Haemonchus contortus were stored in the gas phase of liquid nitrogen, thawed and used to infest worm-free sheep from which, in turn, larvae were cultured, frozen and thawed. This cycle was repeated 5 times. Thereafter, the progeny of the cryopreserved larvae were compared with the progeny of the original untreated larvae for susceptib...
