Tracheo-bronchial aspirates (TBA) can be used as a reliable sample for the diagnosis of lower respiratory tract affections in cattle. Percutaneous tracheo-bronchial aspirate sampling was performed in 173 standing conscious cattle using two types of catheters. Fifty four cows were sampled with Large Animal transtracheal wash Kit (MILA International, Inc. USA) and 119 with infant feeding tube. Cytologic analysis of TBA smears was performed to assess the diagnostic utility of samples. Diagnostic samples were obtained in 87.8 per cent cows (152/173). Sampling using commercial catheter and infant feeding tube retrieved diagnostic samples in 90.7 per cent and 86.6 per cent of cows, whereas repeated infusions were required in 61.2 per cent and 78.7 per cent of cases, respectively. None of the cows exhibited complications post sampling. Infant feeding tube (7 Fr) with 10 G steel introduction catheter was effectively used in the collection of TBA and was comparable with commercial catheter.

Parasites are one of the most common diseases that affect most organisms. The worm Aspiculuris tetraptera is a common intestinal parasite of Mus musculus and rats, it is spread around the world. Aspiculuris tetraptera infection remains a problem for modern research groups; They should be excluded and monitored in rat populations due to their effects on animal health. Methods: The present study was conducted to assess the anthelmintic activity of Laurus nobilis extract in mice naturally infected with Aspiculuris tetraptera. Used was Thirty-six adult male and female (C57BL/6) mice, naturally infected with Aspiculuris tetraptera, were divided into six groups, each comprising six mice: Group 1, was the negative control (infected, untreated), and Groups 2, 3, 4, and 5 were treated with 50, 100, 200 and 400 ìg/ml of L. nobilis for 5 days respectively. Group 6 was treated with 10 mg/mL Albendazole for 3 days as a positive control. Different six treatments were used to test Aspiculuris tetraptera worms in vitro, Containing 4 concentrations (50, 100, 200 and 400 mg/ml) of L. nobilis extract. Ten actively moving adult worms were then placed in each petri dish at room temperature. A saline solution and 10 mg/ml of Albendazole were prepared and used as negative and positive controls. After treatment, observations were made by recording the death time for worms at 20, 40, 80, 120 and 180 minutes. Worms are considered dead if they do not move for 30 seconds after touching their body parts using a surgical needle and the petri dish is shaken. Result: The analysis of phytochemicals by FT-IR for alcoholic extracts of L. nobilis extracts revealed the presence of 15% effective chemical ingredients responsible for killing worms’ activity. In vitro, worms died in 20, 40, 80, 120 and 180 minutes. Attained 96% and 100% after 180 minutes at the highest concentrations (200 and 400 mg/ml).
