Mucus is a thinner secretion from your nose and sinuses. Phlegm is thicker and is made by your throat and lungs.

Amphophilic – It is a term used to indicate that the tissue stains with both the basic and the acidic dyes. Neutrophilic – No special affinity for either the basic or acidic components of a dye.

Acidic stain (Anionic stain) Acidic stain are used to stain the positively charged components such as background staining. histone protein is positively charged so it can be stained by acidic stain. Acidic stain can not stain bacterial cell due to repulsion of same charge. Examples: Eosin, Nigrosin, India ink.

• Types of staining techniques. Simple staining.
• Differential staining. (Use of of single stain)
• (Use of two contrasting stains) Direct.
• Indirect. Separation.
• Visualization. (Positive)
• (Negative) into groups. of structures.
• Gram stain. Flagella stain.
• Acid fast. Capsule stain.

Take a very deep breath and hold the air for 5 seconds. Slowly breathe out. Take another deep breath and cough hard until some sputum comes up into your mouth. Spit the sputum into the plastic cup.

It is usually thick, cloudy and sticky. Sputum is not saliva (spit) as saliva comes from your mouth and is thin, clear and watery.

You cannot get TB germs from: Saliva shared from kissing. TB is NOT spread through shaking someone’s hand, sharing food, touching bed linens or toilet seats, or sharing toothbrushes.

CDC: TB treatment can now be done in 3 months.

By the dawn of the 19th century, tuberculosis—or consumption—had killed one in seven of all people that had ever lived. Throughout much of the 1800s, consumptive patients sought “the cure” in sanatoriums, where it was believed that rest and a healthful climate could change the course of the disease.

Although relatively little is known about its frequency before the 19th century, its incidence is thought to have peaked between the end of the 18th century and the end of the 19th century.

Left untreated,TB can kill approximately one half of patients within five years and produce significant morbidity (illness) in others. Inadequate therapy for TB can lead to drug-resistant strains of M. tuberculosis that are even more difficult to treat. Not everyone who inhales the germ develops active TB disease.

Death remains a common outcome for patients with TB. Case-fatality rates are reported to be between 7% and 35% [17–19]. Delayed treatment and infection with multidrug-resistant strains of mycobacteria are associated with increased risk of death [20–22].

Tuberculosis is curable and preventable. TB is spread from person to person through the air.

Persons who have been Recently Infected with TB Bacteria Persons who have immigrated from areas of the world with high rates of TB. Children less than 5 years of age who have a positive TB test. Groups with high rates of TB transmission, such as homeless persons, injection drug users, and persons with HIV infection.

Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. Not everyone infected with TB bacteria becomes sick.
