Ph.D.MicrobiologyMicrobiology:
It is science that deals with micro – organisms that cannot visible in the naked eyes, encompasses the study of organisms that cause the disease; the host response to infection & the ways in which such infection may be prevented
dental student study microbiology by basic understanding of general and medical microbiology and detailed about the clinical oral microbiology in order to diagnosis oral microbial infection which are intimately related to the overall treatment plan for their patients. Moreover the two major oral disorders are caries and periodontal disease
The cellular organisms classified into .
.Eukaryotes : a- alge , b- fungi c-protozoa
Prokaryotes : bacteria
Eukaryotes
It is the organism have true nucleus surrounded by membrane its also contains membrane-bound organelles such as Golgi bodies & chloroplast, there are metabolic function and energy conversion chromosomes present in the nucleus of microorganism there are two types of cell division sexual& A sexual,DNA is complex with histone proteins, peptidoglycan is not present in the cell wall in these microorganisms
. Prokaryotes:
organisms related to this group don’t have nucleus; chromosomal DNA is in a circular loop &a plasmid they have few internal structures in the cytoplasm on this group, peptidoglycan present in cell wall of these group,the cell division occur by a process called binary fission
