Answer:
BacterialDiseases
1. Typhoid
Causative Organism: Salmonella typhi
Mode of Transmission: Pathogens generally enter the small intestine through contaminated food and water and migrate to other organs through blood.
Diagnostic Test: Widal Test
Symptoms: High fever b(39° to 40°C), weakness, stomach pain, constipation, headache & loss of appetite.
2. Pneumonia
Causative Organism: Streptococcus pneumoniae and Haemophilus influenzae
Mode of Transmission: A healthy person acquire the infection by inhaling the droplets/ aerosols released by an infected person or by sharing glasses and utensils with an infected person.
Diagnostic Test: Blood Test/ Sputum Test.
Symptoms: Alveoli get filled with fluid leading to problem in respiration, fever, chills, cough & headache.
3. Plague/Bubonic plague (Black death)
Causative Organism: Yersinia pestis
Mode of Transmission: Spread by flea bites (Xenopsylla)
Diagnostic Test: Sputum Test
Symptoms: High fever & bubo (lump) in the groin or the armpit. Red patches appear on skin which turn black and leads to death.
4. Cholera
Causative Organism: Vibrio cholerae
Mode of Transmission: Contaminated food and water.
Diagnostic Test: Stool Test
Symptoms: Frequent stools which are white like rice-water & repeated vomiting.
5. Diphtheria
Causative Organism: Corynebacterium diphtheria
Mode of Transmission: Direct contact with infected person or through the air.
Diagnostic Test: Throat Culture
Symptoms: Sore throat, chills with mild fever, vomiting & headache. Throat and tonsils show grey membrane which may spread down and cause hoarseness and difficulty in breathing.
5. Tuberculosis (TB) (Koch's disease)
Causative Organism: Mycobacterium tuberculosis
Mode of Transmission: By airborne particle called droplet nuclei.
Diagnostic Test: Mantoux Test
Symptoms: Fever, cough, Sputum containing blood, pain in the chest, loss of weight, excessive fatigue, loss of appetite, rise of temperature in evening, hoarseness of throat, night sweating & rapid pulse.
6. Tetanus (Lock Jaw)
Causative Organism: Clostridium tetani
Mode of Transmission: Direct transfer of C. tetani spores from soil, excreta of animals, wound & cut.
Diagnostic Test: Physical exam
Symptoms: Irritability and restlessness, the neck becomes stiff and there is difficulty in chewing and swallowing, spasms of muscles of the jaw and face.
7. Leprosy (Hansen's Disease)
Causitive Organism: Mycobacterium leprae
Mode of Transmission: Nasal secretion or droplets
Diagnostic Test: Serology
Symptoms: Appearance of light coloured patches on the skin, thickening of the nerves, ulcers & skin eruption.
Answer:
P(X)=x-x-6
p(3)=3-3-6
=0-6
=-6 and
p(-2)=-2-(-2)-6
=-2+2-6
=0-6
=-6
then 3 and -2 are the zeros of the polynomial
