ISOLATION OF FOOD-POISONING BACTERIA ( Salmonella) The Salmonellas are rod-shaped bacteria which are l-3|i in length and 0.5 - 0.7|i in width. They are gram negative, mostly motile with peritchous flagella. They can grow in presence or absence of oxygen. They ferment glucose only and do not produce urease. There are 1,200 named..

Clinical symptoms

Generally, a person infected with HIV does not show any apparent symptoms for a number (3 to 12) of years. Ten to fifteen percent infected people may, however, suffer from mild fever, headache and uneasiness for sometime after a few weeks of infection. Soon, these symptoms disappear, and infected persons continue transmitting the virus to ..

clinical use

Calcium is present in serum in three forms (i) calcium bound to proteins; (ii) calcium bound to other organic substances e.g. citrate; and (iii) ionized calcium. Most of the physiological functions of calcium depend upon the ionized fraction, but for routine work only total calcium in serum is estimated. A convenient and commonly used meth..

. For example, RFLP analysis can also be used for prenatal diagnosis of certain genetic defects, if the nucleotide sequence or at least the location of the gene is known. A variation on standard RFLP analysis, popularly known as DNA fingerprinting, is increasingly used in forensic medicine to help convict or clear a suspect; a class of R..

. Surrounding all these is a phospholipid membrane or envelope. It is derived from the membrane of the host cell. The envelope has projections called spikes. They are made up of glycoprotein (gp). They are named gp 120 and gp 40. They are meant for binding to receptors of the infecting cells. 2. Life Cycle. HIV infection begins when it attacks the..

MERCURY THERMOMETER OR CLINICAL THERMOMETER

">1. Mercury freezes at - 39C and boils at 357C. Moreover, it has uniform coefficient of expansion over a wide range of temperature. So, the range of the mercury thermometer is quite wide. 2. Since mercury is a good conductor of heat therefore it quickly attains the required tem^ 3. Mercury does not wet glass. So, the rise and fall of mercury in t..

DNA 'proofreading" and DNA repair

Usually, about an hour or so after DNA replication, the cell enters into the division phase. This interval is a period of active "proofreading" and repair of the replicated DNA. In this process, the same DNA polymerase and DNA ligase enzymes which steer replication detect the areas of unmatching nucle..

plasmid dna and chromosomal dna

7. Conjugation Bacterial conjugation provides another evidence to state that DNA is the genetic material. Conjugation is the temporary union of two bacteria for the transfer of genetic materials. There are two types of bacteria, namely F + cell or male cell and F - cell or female cell . The F + cell has a do..
