Research unearths bacteria cells jointly give birth to diseases

JAMSHORO: A faculty member of Sindh University Dr. Abdul Nabi Mirjat has discovered that bacteria cells communicate with one another and they give birth to different diseases like pneumonia when they are gathered on a single platform.

He unearthed it in his PhD thesis which he completed on the topic “Quorum-sensing (QS)” in microbiology at Ocean University Qingdao, China. He recently returned home from China and held a courtesy meeting with vice chancellor of Sindh University Prof. Dr. Abida Taherani here on Wednesday.

Dr. Mirjat told the vice chancellor that he has also done a one year course of Chinese language in a bid to have command on it.

Dr. Taherani congratulated him over completing his PhD in microbiology in time from China and hoped that he would be sharing with his academic & research experiences with his students on the campus.

He said, “His study reveals that a single bacterium was not able to create any disease but when the bacterial cells mingle with one another, they create diseases which harm human health.

The scholar in his research further revealed that the bacteria produced some particular type of chemicals such as N-acyl homoserine lactones (AHLs) and through these chemicals, the tiny bacteria cells communicated with one another & expressed certain genes to perform various biochemical and physiological functions.

“Quorum-sensing is a communication system used by various bacterial species”, he said, adding that with the help of a mechanism setup, the prokaryotic cells can behave like eukaryotes”, said Dr Mirjat in his findings.
