Enzyme-based metabolic mechanisms of insecticide resistance were investigated, comparing a deltamethrin-susceptible parent stock and resistant colonies of Anopheles minimus species A using biochemical assays. The control parent colony was determined susceptible to the diagnostic lethal concentration of deltamethrin (0.05%), whereas the 6 resistant test populations at selected 4, 8, 12, 14, 16, ...

Introduction: It is often difficult to ascertain how Salmonella issues in poultry begin and what measures should be implemented to prevent them. Chickens may become colonized through both vertical (from parent stock) and horizontal (environmental) means. This purpose of this article is to detail how Salmonella colonize poultry and to explain effective measures for preventing or controlling colo...

Background Vertical integration of the broiler industry allows producers to combine different biosecurity and sanitation practices, housing technologies, and feeding regimens to improve food safety. The purpose of this study was to investigate the prevalence and distribution of Salmonella, to determine the source of Salmonella contaminants, and to reveal the relationships between isolates at ea...

One hundred and eighty lachrymal glands obtained from 90 broiler chickens originating from a commercial stock, equal number from both genders at the age of 1, 7, 14, 21, 28, 35, 42, 49 and 56 days were investigated. After the narcosis, decapitation and glandular preparation, using paraffin and frozen sections an evaluation of the gland polysaccharides was carried out following the conventional ...

The purpose of this study was to investigate the distribution of Salmonella species in an integrated broiler supply chain in Korea. A total of 1,214 samples from various steps of an integrated broiler production company including broiler breeder farms, broiler farms, broiler trucks, slaughterhouse, and retail chicken meats were collected and investigated. Salmonella was detected in 195 of the s...
