Reduction of Ascaridia galli Pathology by Salmonella typhimurium in Broiler Chicken.

Previous studies have reported interactions between spp. and some helminth coinfections. In this study, and coinfections were analyzed, and the consequences on therapy were proposed. In a first experiment where the effect of the bacteria on the nematode was evaluated, thirty 42-day-old broiler chickens were divided into 3 groups and coinfected with both parasites. The rate of egg inoculum was kept constant at 500/ml while that of varied as follows: T (500 eggs/ml), T (500 eggs/ml+104 CFUs), and T (500 eggs/ml +10 CFUs). EPG and parasitic load were measured using the McMaster technic, and number of worms and their length were also measured. We observed that T containing 10 CFUs of significantly reduced the EPG values, and this group recorded the lowest worm load ranging from 18 to 21 worms. Likewise, the length of the worms obtained with T and T appeared to be shorter than those of the control (T). In a second experiment to assess the effects of the nematode on the bacteria, thirty 42-day-old broiler chickens were divided into 3 groups and coinfected with both parasites. The rate of inoculum was kept constant at 10 CFUs while that of varied as follows: T (10CFUs), T (500 eggs/ml +10 CFUs), and T (750 eggs/ml +10 CFUs). Bacterial load was measured using Voogt technique. We observed that T increased the colonization time and prolonged the duration of secretion. appears to be a hyperparasite considering the deleterious effect on . Due to this, it may be prudent to combine anti- treatment with anthelmintic so as to effectively treat pathologies caused by these two pathogens.
