3. INTRODUCTION
 Airborne diseases are caused
by pathogenic microbes that can be
transmitted through the air.
 The relevant pathogen may be
viruses, bacterial, fungi.
 These can be transmitted through
breathing, talking, coughing,
sneezing, laughing, raising of dust,
spraying of liquids, toilet flushing
and close personal contact or
aerosolization of the microbe.
 The discharged microbes remain
suspended in the air on dust particles,
and water droplets.

DISEASES IN HUMAN
Bacterial airborne disease are:-Tuberculosis, pneumonia,
diphtheria, whooping, etc.
Bacterial airborne disease effects:-
Allergens causes inflammation in the nose, throat and the
lungs.

7. Tuberculosis is commonly called TB.
 It is a contagious bacterial disease.
It is cause by mycobacterium.
Transmission spread from person to person through air.
The bacterial can attack any part of the body, but it most commonly stick to
the lungs and causes TB of lungs.
Treatment by antibiotic (isoniazid and rifampicin).

8. SYNPTOMS OF
TUBERCULOSIS

9. Pneumonia
Lower respiratory tract infection.
Cause by streptococcus pneumonia.
A serious illness of the lungs which makes breathing difficult.
Transmission through airborne respiratory droplets (sneezes).
Treated by antibiotics (azithromycin or erythromycin) along
with rest and drinking plenty of water.

PNEUMONIA

11. Diphtheria is an infections disease of the upper respiratory tract
Disease cause by corynebacterium diphtheria.
It is an gram positive bacillus.
Transmission through airborne respiratory droplets (sneezing) and saliva.
The membrane can obstruct breathing.
Treated by antibiotics (penicillin or erythromycin)

13. PREVENTION
Maintain good personal hygiene.
Wear a mask properly
Keep the environment clean and hygienic.
Wash your hand after sneezing.
Adopt a healthy lifestyle.
Stay away from sick people.
Ensure good ventilation.

14. TYPES AND EFFECTS OF BACTERIALAIR
BORNE DISEASES ON PLANTS
Bacterial disease can be damage to plant tissue and the symptoms
that they cause, which may include vascular wilt, necrosis, soft rot,
and tumors.
Bacterial diseases are influenced greatly by temperature and
moisture.
Airborne bacterial diseases such as fire blight, soft rot, crown gall,
citrus canker.
CITRUS CANKER WATER-SOAKED ON
LEAFS
SPOTS ON STEMS

15. FIRE BLIGHT
The oozing bacterial are carried by insects, wind, and rain to infect new plants
and tissues.
It is an contagious disease affecting apples, pears.
Cause by Erminia amyluria.
The spread intercellularly and upto 1.2 meters (4feet) through vascular tissue in
the wood, during late spring and early summer, darkening, and killing the tissue.
INFECTED PEARS BROWN SPOTS ON STEMS

16. SYMTOMS
Apple plant affected
by fire blight
Pear plant affected by
fire blight
Brown spots on stem
Blossoms appear
water-soaked on leafs

17. CITRUS CANKER
It mainly affects on citrus plants.
It cause lesions on leaves, stems, and fruits of plants.
There is no cure for citrus canker.
Prevention is the best option to protect against citrus canker.
Citrus canker high contagious and can be spread rapidly by:-
Wind-driven rain
Infected took and equipment's.
Exposed plants.
FRUIT RIND BLEMISHING
DISEASE
WATER-SOAKED ON LEAFS

18. SYMTOMS
Water-soaked appearance.
Fruit rind blemishing
disease.
Brown spots appearance on
stem also.

19. PREVENTION
Infected wood should be removed in late summer or
winner when the bacteria are not actively spreading.
Using canker disease-free nursery plants.
Pruning and burning infected twigs.
Spraying copped-based bactericides.
Developing canker resistant varieties.
