Abstract

Aim: The objective of the present study was to determine the effect of some types of probiotics to minimize the hazard effect of cadmium on Oreochromis niloticus (O. niloticus) and to determine the influence of probiotics on the growth performance and immune status of O. niloticus. 

Methods: Fish were divided into four groups, the first one was fed on a diet without any additives (control group), and the second group was fed on diet with the addition of 0.1 from (LC50) of cadmium 32 ppm in water. The third group was fed on a diet containing 1 gm/kg of Lactobacillus acidophilus. The fourth group was fed on a diet containing 1 gm/kg of L. acidophilus with 0.1 addition from (LC50) of cadmium 32 ppm.

Results: The experiment lasted about 60 days which resulted in an improvement in growth performance, with a decrease in the number of micronucleus formation in the group which received the probiotic. The group which was affected with cadmium showed decrease in the growth performance with increase in the number of micronucleus formation while the group which received probiotics and treated with cadmium had significant improvement in growth performance and decreased in the number of micronucleus formation.

Conclusions: Probiotics decrease cadmium pollution.

The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.

To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here


 

The 6th World Conference on Research Integrity (WCRI) is to be held on June 2-5, 2019 in Hong Kong.

The WCRI is the largest and most significant international conference on research integrity. Since the first conference in Lisbon in 2007, it has given researchers, teachers, funding agencies, government officials, journal editors, senior administrators, and research students opportunities to share experiences and to discuss and promote integrity in research. Read more:
