despite of beneficial effects of antibiotics in treatments of infectious diseases, antibiotic residues in meat, milk, eggs and another products can cause serious side effects for human health. it is clear that, antibiotic residues in food stuff, cause bacterial resistance, allergic reactions, toxicity, carcinogenic effects and change of natural micro flora of intestine in consumers. so, the aim...

background: the presence of antibacterial drug residues in food caused many concerns for consumers. this study was designed to determine of antibacterial drug residues in commercial eggs distributed in urmia, iran.  methods: disc diffusion microbial inhibition test was performed using three media seeded with bacillus subtilis at different ph values (6, 7.2 or 8) and a fourth medium seeded with ...

Abstract Background The pink bollworm, Pectinophora gossypiella , is the most destructive pests of cotton plant in Egypt. Due to several problems insecticides, present study was conducted evaluate toxicity effect entomopathogenic fungi (EPF), Beauveria bassiana and Metarhizium anisopliae against different stages (Saunders) (Lepidoptera: Gelechiidae) Results fungal isolates exhibited a toxic tre...

In the Northeast of Brazil, expansion of guava crops has been impaired by Meloidogyne enterolobii that causes root galls, leaf fall and plant death. Considering the fact that arbuscular mycorrhizal Fungi (AMF) improve plant growth giving protection against damages by plant pathogens, this work was carried out to select AMF efficient to increase production of guava seedlings and their tolerance ...

The health status of goshawk chicks (Accipiter gentilis) from the nests in the vicinity of Wrocław was evaluated. The research was conducted in spring 2001. Each nest was inspected three times at different phases of the reproduction period and the protocol included: the counting of eggs in each nest, clinical examination of chicks, collecting swabs from the crop and cloaca, blood and litter sam...

A wild type strain ofVerticillium lecanii and a mutant strain with increased tolerance to the fungicide benomyl were evaluated in greenhouse experiments for effects on Heterodera glycines populations. Nematodes were applied at 300 eggs and juveniles per 4,550-cm(3) pot (two soybean plants in 4,990 g loamy sand per pot) and at both 300 and 10,000 eggs and juveniles per 1,720-cm(3) pot (one soybe...

The role of Pasteuria penetrans in suppressing numbers of root-knot nematodes was investigated in a 7-year monocuhure of tobacco in a field naturally infested with a mixed population of Meloidogyne incognita race 1 and M. javanica. The suppressiveness of the soil was tested using four treatments: autoclaving (AC), microwaving (MW), air drying (DR), and untreated. The treated soil bioassays cons...

An experiment was conducted to evaluate the tolerance of micropropagated and mycorrhized alpinia plants to the parasite Meloidogyne arenaria. The experimental design was completely randomized with a factorial arrangement of four inoculation treatments with arbuscular mycorrhizal fungi (AMF) (Gigaspora albida, Claroideoglomus etunicatum, Acaulospora longula, and a non-inoculated control) in the ...
