Methionine

Methionine was first isolated in 1922 by the American chemist John Howard Mueller.

He identified it while studying proteins and bacterial nutrition.

Mueller discovered that certain bacteria required a previously unknown sulfur-containing amino acid for growth—this compound was later named methionine.

Methionine (Met) is a vital sulfur-containing amino acid that serves as a cornerstone for bacterial life and host-microbe interactions.

                                              World War 1: STI causes Troop Losses 

In earlier wars (like World War I), STIs caused significant troop losses, prompting stricter control in WWII. 

The First World War served as a breeding ground for sexually transmitted diseases. The number of these infections grew massively during the war and eventually spread to the unaffected populous. The most common sexually transmitted infections were gonorrhea and syphilis which quickly spread amongst the troops and weakened their fighting capabilities. At that time, the cure for venereal disease was very expensive, time-consuming and largely ineffective. 

 

                                                         World War 1 To World War 2

During World War II, there was an urgent need to screen military personnel for sexually transmitted infections.  

The VDRL test was formally developed in the 1940s at the Venereal Disease Research Laboratory, part of the United States Public Health Service.   

The VDRL test became a key public health tool because it could be easily deployed on a mass scale.

Rapid Plasma Reagin Test

 

 

The Rapid Plasma Reagin test is a non-treponemal, macroscopic, flocculation-charcoal card agglutination test developed in the 1950s and 60s to screen for syphilis.

 It acts as a faster, more accessible improvement on the VDRL (Venereal Disease Research Laboratory) test by detecting reaginic antibodies—which arise from tissue damage caused by T. pallidum—using cardiolipin antigen, charcoal particles, and choline chloride.
