Submitted (24-MAR-2016) to the DDBJ\/EMBL\/GenBank databases.
The Cymothoidae are a family of isopods in the suborder Cymothoidae and are found in marine and freshwater. Cymoithoids are ectoparasites, fish. There are around 40 genera and more than 380 species of Cymothoidae which were identified.

<\/p><\/div>

Characteristics:<\/span><\/strong><\/p>

1-They produce anticoagulants and suck the fish’s blood.
2-Different species of parasite included in the skin, fins, the gills and the mouth, and some species located in muscles.<\/p>

Biology:<\/span><\/strong><\/p>

1- Cymothoids are protandrous hermaphrodites.
2- Each juvenile develops first into a male, but if there are no any females nearby.
3- The male will later become a female and attach permanently to the host.
4- Female is able to secretes pheromones which prevent male cymothoids in the vicinity from becoming female.<\/p>

Accession No.: LC130572
Submitted (05-MAR-2016) to the DDBJ\/EMBL\/GenBank databases.\u00a0Mycobacterium tuberculosis is an obligate pathogenic bacterial species in the family Mycobacteriaceae and the causative agent of tuberculosis.The genome contains 250 genes involved in fatty acid metabolism, with 39 of these involved in the polyketide metabolism generating the waxy coat.<\/p><\/div>

Such large numbers of conserved genes show the evolutionary importance of the waxy coat to pathogen survival. Chaperonin sequences are useful for phylogenetic studies and have been widely exploited in studies of prokaryotic and eukaryotic evolution. Group I chaperonin sequences have also been employed as targets for detection and identification of organisms since a 549-567 bp segment of the cpn60 coding region, the “universal target”, can be amplified with universal PCR primers.<\/p>
