lecture 2- rotavirus

Rotavirus is causative agent for diarrhea disease at children below 5 years. This virus could cause the mortality to 608,00 children at developer country (Choi et al, 2005) .Infected children has several symptoms such as fever, diarrhea and hydration. This virus was in reoviridae family with others virus like Orthoreovirus, Orbivirus, Cypovirus, Phytoreovirus and Fijivirus. Electron microscope observation mention that rotavirus had an icosahedral form as like as motorcycle wheels. Rotavirus has seven groups those are Rotavirus A, B, C, D, E, F and G.

Rotavirus A is important agent that can cause gastroentritis among children. Rotavirus was spread to person by human oral route. Rotavirus is non enveloped virus. They has double strand RNA genom and has proteins suchs as VP6, VP7, VP9 and VP4.

Peptidoglycan

Lecture 1- Peptidoglycan

Microorganism is small particles that Can't see by your eyes. There have many types of microbes, one of the type is bacteria. Bacteria got two group. Gram positive bacteria and gram negative of bacteria. Gram positive bacteria consist a thick peptidoglycan, meanwhile gram negative bacteria consist thin peptidoglycan. Peptidoglycan compose sugar and proteins. Peptidoglycan is very important to bacteria because, its will strengthen the structure of bacteria. Without peptidoglycan, bacteria easy to destroy and lysis.

From the info, scientist can generate a medicine or antibiotic to destroy the peptidoglycan in bacteria. Maybe the antibiotic will attack the peptidoglycan and destroy bacteria (pathogenic) in human body.

For more information, the blog will give the structure of peptidoglycan and we also provide the content in peptidoglycan. From the information, i hope scientist got idea to generate a medicine or antibiotic to destroy the pathogenic bacteria in human body.













All bacteria have a peptidoglycan to strengthen their structure.












Peptidoglycan consist a N-acetyl glucosamine and bridge of tetrapeptide.
