While a majority of bacteria in the human body are countered by the immune system, there are a few that are pathogenic in nature. Pathogenic bacteria cause infectious diseases like leprosy, cholera, anthrax, and bubonic plague.uberculosis is an infectious disease. The bacteria that cause tuberculosis are called mycobacterium tuberculosis. People with TB or tuberculosis cough excessively and suffer a terrible pain in the chest. They cough up blood and display excessive weight loss, fatigue, loss of appetite, and persistent fever.
Titration, also known as titrimetry, is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte.Since volume measurements play a key role in titration, it is also known as volumetric analysis.A reagent, called the titrant or titrator is prepared as a standard solution. A known concentration and volume of titrant reacts with a solution of analyte or titrand to determine concentration.n assay is a form of biological titration used to determine the concentration of a virus or bacterium. Serial dilutions are performed on a sample in a fixed ratio (such as 1:1, 1:2, 1:4, 1:8, etc.) until the last dilution does not give a positive test for the presence of the virus.
Report Abuse. Complexometric titration (sometimes chelatometry) is a form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration. Complexometric titrations are particularly useful for the determination of a mixture of different metal ions in solution.
