TUBERCULOSIS(TB) 
? TB is caused by two types of bacteria 
mycobacterium tuberculosis and M.bovis 
? The bacteria are spread from persons to 
persons as aerosolised droplets produced 
when the affected persons coughs or sneezes 
? The form of TB caused by M.bovis also occurs 
in cattle and spread to humans in meat and 
milk
Diagnosis 
? Diagnosis is by the tuberculin or mantoxu test 
? Where a purified protein derivative from the 
bacterium is injected in to the skin of the 
suspected patients. 
? Development of a red ,raised around the 
area of injection indicates an infection
Bacterial diseases
treatment 
? Treatment is by multidrug antibiotic therapy, 
which has to be continued for a long time 
until the bacteria are completely eliminated 
? Infection can be prevented by vaccination 
with BCG(Bacilli Chalmette Guerrin)
DIPHTHERIA 
? Diphtheria is a disease of the upper 
respiratory tract , caused by the toxin 
produced by the bacterium corynebacterium 
diphtheria
pathogenesis 
? The bacterium infects its victim when the person 
inhales contaminated respiratory droplets from 
an infected person and rapidly colonies the 
upper regions of the respiratory tract 
? It produces an exotoxin that inhabits protein 
synthesis in the epithelial cells killing them 
? As dead tissues accumulate the toxins mixes 
with the mucus secretion ,white blood cells and 
the colonies of bacteria forming a thick leathery 
greyish black membrane like material blocking 
the respiratory tract
Bacterial diseases
treatment 
? : vaccination against diphtheria has to be 
taken at infancy using the DTP vaccine
pneumonia 
? Pneumonia is an infectious disease of the 
lower respiratory tract in the bronchial tubes 
of the lungs
Bacterial diseases
Mode of infection and treatment 
? Infection is acquired when a person inhales 
or comes in to contact with aerosolic droplets 
droplets from infected peoples 
? Treatment is administration of antibiotics 
such as penicillin, tetracycline and 
chloramphenicol
LEPROSY 
? IT is a chronic contact communicable disease 
caused by Mycobacterium leprae 
? It spread through direct contact with infected 
people or their clothing or through 
aerosolised respiratory discharges from 
infected peoples
