Tetracycline Resistance among Isolates from Broilers in Iran: A Systematic Review and Meta-Analysis.

Background: Avian colibacillosis are infections caused by Avian Pathogenic which causes high morbidity, high mortality, and significant economic losses. Antibiotics such as tetracycline are an important treatment choice for colibacillosis in Iran. However, the irrational use of antibiotics has caused high antibiotic resistance.

Consequently, its control is warranted. The key in controlling bovine tuberculosis is to test and slaughter the infected cows.

Antinociceptive effects, acute toxicity and chemical composition of Vitex agnus-castus essential oil.

Objective: Vitex agnus-castus (VAC) and its essential oil have been traditionally used to treat many conditions and symptoms such as premenstrual problems, mastalgia, inflammation, sexual dysfunction, and pain. In this study, the effects of essential oil extracted from Vitex agnus-castus (EOVAC) leaves were investigated in three behavioral models of nociception in adult male Wistar rats.

Materials And Methods: Chemical composition of EOVAC was analyzed using gas chromatography - mass spectrometry (GC-MS) and also its possible toxicity was determined in mice.
