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.
先前的研究报道了某些物种与一些蠕虫共感染之间的相互作用。在本研究中，分析了[具体物种1]和[具体物种2]的共感染情况，并提出了对治疗的影响。在第一个评估细菌对线虫影响的实验中，将30只42日龄的肉鸡分为3组，同时感染两种寄生虫。[具体虫卵1]的接种率保持恒定为500个/毫升，而[具体虫卵2]的接种率变化如下：T1（500个虫卵/毫升）、T2（500个虫卵/毫升 + 10⁴ 个菌落形成单位）和T3（500个虫卵/毫升 + 10⁵ 个菌落形成单位）。使用麦克马斯特技术测量每克粪便虫卵数（EPG）和寄生虫负荷，还测量了蠕虫的数量及其长度。我们观察到含有10⁵ 个[具体细菌]菌落形成单位的T3显著降低了EPG值，并且该组记录的蠕虫负荷最低，为18至21条蠕虫。同样，用T2和T3获得的蠕虫长度似乎比对照组（T1）的短。在第二个评估线虫对细菌影响的实验中，将30只42日龄的肉鸡分为3组，同时感染两种寄生虫。[具体细菌]的接种率保持恒定为10⁵ 个菌落形成单位，而[具体虫卵2]的接种率变化如下：T4（10⁵ 个菌落形成单位）、T5（500个虫卵/毫升 + 10⁵ 个菌落形成单位）和T6（750个虫卵/毫升 + 10⁵ 个菌落形成单位）。使用沃格特技术测量细菌负荷。我们观察到T5增加了定殖时间并延长了[具体细菌]分泌的持续时间。考虑到对[具体细菌]的有害影响，[具体虫卵2]似乎是一种超级寄生虫。因此，将抗[具体细菌]治疗与驱虫药联合使用可能是谨慎的，以便有效治疗由这两种病原体引起的病症。
