haemato-biochemical studies in rainbow trout infected with saprolegnia were carried out under temperate climatic conditions of kashmir valley to find out the variation in blood parameters. the trial was carried out on 405 cultured rainbow trout fish ranging in length from 47.8 to 69.8 cm and in weight from 1300 to 1920 g. the same experiment was carried out on 2,70000.00 trout fish eggs from no...
Background : Salmonella is a short rod shape, gram-negative, non-encapsulated, aerobic and anaerobic options that cause food poisoning in humans. Raw food of animal origin, particularly meat and eggs of birds have important role in the transfer of this disease. Since duck and turkey eggs are very important in the transmission of Salmonellosis and consuming of local and non-industrial eggs of du...
Introduction: The nematophagus fungi have been suggested as an alternative way to eliminate the zoonotic helminths eggs from the environment. In the present study, we evaluated the ovicidal activity of a fungus, Paecilomyces lilacinus, recovered from a compost soil, on the eggs of parasitic helminths under in vitro condition. Methods: Water suspension of the soil samples collected from differen...
Background and Objectives: Microbial quality, particularly parasitic characteristics in terms of effluent reuse in agriculture is one of the most important indices. The aim of this study is determination of removal efficiency of Kermanshah wastewater treatment(conventional activated sludge) and Gilangharb wastewater treatment plants (stabilization ponds) for cyst and parasitic eggs.Material and...
Background and Aim: Salmonella is one of the common bacterial pathogens between man and birds throughout the world. Inconsistent Salmonella contamination following consumption of eggs, as one of the main contributors of the disease has also become an important public health issue. The aim of this study was to investigate prevalence of Salmonella contamination in locally-produced eggs in Birjand...
Background: The specific antibody response against Newcastle disease virus (NDV) in the blood serum of chickens hatched from eggs exposed to low dose gamma-radiation was studied. Materials and methods: Two groups of eggs of commercial meat chicken lines were irradiated with the dose of 0.30 Gy 60Co gamma-rays before incubation and on the 19th day of incubation, respectively. The same num...
saprolegnia is one of? the? ?most important agents decreasing the eggs survival rate in sturgeon hatcheries. there are some chemical substances for controlling the fungal infection of eggs. in this study, an attempt was made to introduce a ?germ negative bacterium, pseudomonas aeroginosa (ptcc1430)(persian type culture collection) as a biocontrol??ling agent of? ?water mold. saprolegnia was iso...
Hatching studies with Heterodera glycines typically have been conducted with a mixture of egg-mass and encysted eggs. Laboratory research was conducted to compare hatching of H. glycines eggs from external egg masses with that of eggs extracted from within females and cysts (encysted eggs). Egg-mass eggs were collected by soaking infected soybean roots in 0.5% sodium hypochlorite, and encysted ...
Light and scanning electron micrographs of Opisthorchis viverrini, Haplorchis taichui, H. pumilio, A Phaneropsolus bonnei, and Prosthodendrium molenkampi eggs were studied. Under light microscopy. O. viverrini eggs had rough eggshells and prominent shoulders. H. taichui, H. pumilio were similar in shape and had smooth eggshells and prominent shoulders. H. pumilio eggs were bigger than H. taichu...
