Effects of short-term sodium chlorate exposure on pigs.

The present study evaluated the effects of exposure to different doses of sodium chlorate in 10-week-old pigs. Twenty pigs were divided into four equal groups and treated with different doses of sodium chlorate: 0, 125, 250 and 500 mg kg-1 body weight per day via the drinking water for 7 consecutive days. The results showed a significant decrease (P < 0.

Application of a solid-phase fluorescence immunoassay to determine amoxicillin residues in fish tissue.

The present study demonstrates an application of Parallux (a solid-phase fluorescence immunoassay) for amoxicillin analysis in fish tissue. Amoxicillin at the recommended therapeutic dose (400 mg/kg body weight) was orally administered to three groups of 25 olive flounder ( Paralichthys olivaceus ), 25 rockfish ( Sebastes schlegeli ) and 25 red sea bream ( Pagrus major ) for 7 consecutive days. Amoxicillin was detected in the muscle of fish treated by the 3rd day of the withdrawal period.

Biological and antibacterial activities of the natural herb Houttuynia cordata water extract against the intracellular bacterial pathogen salmonella within the RAW 264.7 macrophage.

Salmonellosis is a major bacterial zoonosis that causes a variety of disease syndromes, from self-limiting enteritis to fatal infection in animals and food-borne infection and typhoid fever in humans. Recently, the emergence of multidrug-resistant strains of Salmonella sp. has caused more serious problems in public health.

Ceftiofur distribution in plasma and tissues following subcutaneously administration in ducks.

A study was performed to determine the residues in blood and edible tissues of healthy ducks (25 days old, mean body weight 1.0+/-0.13 kg) after subcutaneous administration of ceftiofur sodium at a dose rate of 2 mg/kg body weight (Group I) and 4 mg/kg body weight (Group II).

Application of a solid-phase fluorescence immunoassay to determine oxytetracycline and tetracycline residues in tissue of olive flounder (Paralichthys olivaceus).

Parallux, a solid-phase fluorescence immunoassay (SPFIA) developed for antibotics residue detection in milk, was applied for analysis of fish tissue. The recommended therapeutic doses of oxytetracycline (OTC, 100 g/ton water, withdrawal period 30 days) and tetracycline (TC, 150 g/ton water, withdrawal period 30 days) were treated to a group of 35 olive flounders (Paralichthys olivaceus) using dipping administration. Muscle was sampled before and after drug treatment 1st, 2nd, 3rd, 5th, 7th, and 14th day.
