The screening of microorganism for antiparasitic agents produces a variety of compounds like avermectins and different discoveries have focused on the nafuredin, atpenins, argifin, and argadin. Nafuredin shows anthelmintic activity against Haemonchus contortus in sheep which is a -specific inhibitor of electron-transport enzyme. The atpenins are reported to be the most powerful complex II inhibitors. The study of co-crystallization of atpenin A5 and E. coli complex II demonstrated the binding mechanism of ubiquinone to complex II. The argifin and argadin are the first cyclic peptides to inhibit chitinase at little concentration. By structure they are similar but their chitinase inhibition mechanisms are different.

This article has covered the study ofmicrobial products and the producing strain. It has been proved that avermectins is significant as health agent of animals and human medication. This study has focused on the genome-sequencing analysis of Streptomyces avermectiniu. However, the gene clusters of secondary metabolites was anticipated to be more than 30 in numbers as 6.6% of total genome DNA has been used for gene clusters of secondary metabolites. It is proved that the isolation and screening of genes of microorganisms provides number of opportunities for the exploration of many more novel and greatly needed drugs medicines, reagents, and other products from different bioenvironments, using different methods, and with the application of gene technology and the introduction of new screening methods. The biologically fascinating microbial products argued in the article have given essential scientific information for use in the life sciences, such as biochemistry and medicine.
