Disease Causative Agents

Correct answer. Pneumonia – Bacterial disease; caused by Diplococcus pneumoniae Leprosy – Bacteria disease; caused by Mycobacterium leprae Plague – Bacterial disease; caused by Bacillus Yersinia pestis

This is the correct option. Cancer is not a water borne disease that is caused due to the drinking of contaminated water.

Conjunctivitis, commonly known as pink eye, is an inflammation or infection of the conjunctiva - the transparent membrane covering the white part of the eye and inner eyelids. The symptoms primarily affect the eyes.

Pullorum disease is a disease of poultry (chickens) caused by Salmonella pullorum, not cattle. Foot and mouth disease, udder swelling (mastitis), and anthrax are all cattle diseases, making Pullorum the correct answer for 'not a cattle disease'.

Bacillus anthracis is the causative bacterium of anthrax, affecting both cattle and humans (zoonotic). Streptomycin is an antibiotic drug, pneumococcus causes pneumonia in humans. Anthrax is indeed transmitted from cattle to humans.

Anthrax is a zoonotic disease caused by Bacillus anthracis that can spread from cattle to humans through contact with infected animals or their products. Foot and mouth disease primarily affects animals and rarely infects humans. Swelling of udder is a symptom rather than a specific disease.

Swelling under the udder in cattle is mastitis, an inflammatory condition primarily caused by bacterial infections (Staphylococcus, Streptococcus, E. coli). While viruses can cause infections, udder swelling is most commonly bacterial in origin.

Smallpox is an infectious disease caused by the variola virus, not by bacteria, protozoa, or fungi. It was one of the most devastating diseases in human history before being eradicated through vaccination in 1980. Viruses are distinct from other pathogens.

Ans-1 Typhoid and Tuberculosis(TB) are bacterial diseases while Malaria is caused by a protozoan.

Correct. Rickettsias, Chlamydias (obligate intracellular pathogens) and Treponema pallidum do not grow on artificial media and Mycobacterium leprae is grown in armadillos because of its low temperature.

Ranikhet disease (Newcastle disease) is a viral disease that primarily affects poultry/chickens. It causes respiratory distress and neurological symptoms and is highly contagious among birds.

Cholera, typhoid, polio, meningitis, hepatitis and dysentery are waterborne diseases.

Mumps is a viral infection that primarily affects the salivary glands, especially the parotid glands which are the largest salivary glands located near the ears. This causes the characteristic swelling of the cheeks and jaw.

This option is correct. Most oral cancers look very similar under the microscope and are called squamous cell carcinoma.
