BACKGROUND Corvidae is a cosmopolitan family of oscine birds including crows, rooks, magpies, jays, chough, and ravens. These birds are migratory species, especially in the shortage of foods, so they can act like vectors for a wide range of microorganisms. They live generally in temperate climates and in a very close contact with human residential areas as well as poultry farms. There is no ava...
this study was conducted to determine the prevalence and effect of parasitic infection on erythrocyte indices in trade camels slaughtered in maiduguri, nigeria. two hundred adult one humped camels comprised of 87 (43.5 %) males and 113 (56.5 %) females were examined for helminths and hemoparasites at their slaughter time according to the standard procedures. an overall prevalence of 79 % for si...
The impacts of two organic soil amendments on nematode abundance, community structure and soil characteristics were studied in field grown tomatoes. We hypothesized that as the raw (labile form) and composted (non-labile form) manures differ in their chemical composition and effect on microbial activity. Also they will have different effects on soil properties and directly and indirectly affect...
A drip irrigation delivery system was used to infest field sites with the plant-parasitic root-knot nematodes, Meloidogyne incognita. Juvenile or egg inocula passed through the system without blockage of emitters or harm to the nematodes. Field sites so infested were available for experimentation. Delivery of approximately 5 x 10 to 10 juveniles or 10 to 3 x 10 eggs per emitter through the drip...
Insulin-like (ins) peptides play an important role in development and metabolism across the metazoa. In nematodes, these are also required for dauer formation and longevity and are expressed in different types of neurons across various life stages which demonstrate their role in parasites and could become possible targets for parasite control. To date, many nematode genomes are publically avail...
examination of faecal samples of 6,430 school children aged between 2 and 20 years, for gastrointestinal parasites using sedimentation and kato smear techniques was carried out in benin city, nigeria between january 1997 and december 1998. four thousand two hundred and thirty six (65.8%) were infected. three species of protozoa and 8 species of helminths were recorded as follows: entamoeba hist...
The effects of vermicomposts on plant parasitic, fungivorous and baterivorous nematode populations were investigated in grape (Vitis vinifera) and strawberry (Fragaria ananasa) field crops. Commercially-produced vermicomposts derived from recycled paper, and supermarket food waste were applied to replicated plots at the rates of 2.5 t ha–1 or 5.0 t ha–1 for the grape crop and 5.0 t ha–1 or10 t ...
the risk of disease spread through water, fruits and vegetables contaminated through unclean waters varies from region to another. springs and underground water resources are essentially free of germs or they have tolerable levels of germs; unless they are infected by surface water or human excreta. scientific reports have shown that outbreaks of food-borne illnesses especially foods such as fr...
