8. Clinical findings
⚫ Rapid, shallow respiration
⚫ dyspneaoccurring in the laterstages.
⚫ Polypnoea.
⚫ Cough
⚫ Bronchopneumonia - moist painful cough,
⚫ interstitial pneumonia -, dry, backing cough,
⚫ nasal discharge mayor may not be presentsaccompanying inflammation of
the upperrespiratorytract.
⚫ Auscultationof the thorax beforeand aftercoughing maydetect exudate in the
airpassages.
⚫ thevascular murmur is increased.
⚫ Moist ralesdevelop in broncho-pneumoniaas bronchiolarexudation increases
⚫ in uncomplicated interstitial pneumonia, clear, harsh bronchial tones are
audible.
⚫ Fever
⚫ anorexia,
⚫ depression,
⚫ an increase in pulserate.
9. Treatment
⚫ Isolationof affected animals
⚫ Affected animals should be housed in warm, well ventilated, draft-
free accommodation, provided with ample, fresh water, and light
nourishing food
⚫ Antimicrobial agents e.g. Sulphadimidine(33.5%) solution @ 15-
30ml/50kg B.W. I/V or S/Cly, oxtetracycline @ 10-20 mg/kg BW I/m or
I/V for 7 days, Penicillin @ 20-40 lakh IU for LA for 5-7 days
⚫ In parasitic Pneumonia- Levamisole, Fenbendazole
⚫ In fungal- Grisovin, Amphotericin-@ 0.5 mg/Kg BW
⚫ Corticosteroids fortheiranti-inflammatorye.g. Dexamethason
⚫O2 supply
⚫Expectorants, e.g. Zeet Expectorant, Pot iodide
⚫VitC & Calcium
10. Aspirition pneumonia (Drenching pneumonia,
Foreign body Pneumonia, Regulation pneumonia,
Inhalation pneumonia, Mechanical pneumonia
⚫Etiology:
⚫Careless drenching.
⚫Careless passage of stomach tubeduring relieveof other
diseases.
⚫Vomiting in ruminantsand horses that followed by
aspiration.
⚫Paralysisof the pharynx & larynx
11. Symptoms:
⚫Death occursquickly
⚫Signs of pneumoniaare present
⚫Coughing
⚫Rales,
⚫foamy nasal discharge
⚫Protrusionof tongue
⚫feted odors breath,
⚫Congested mucosa
⚫ Rapid pulsation & febrilecondition.
⚫Thecondition is usually followed bygangrenous
pneumonia
12. Treatment
⚫If the lesion is advanced, treatment is non effective,
⚫using broad spectrumantibiotic & sulfonamides.
⚫Careof theanimalsand supportiveremedies &
sedatives
13. Lung worm infestation
(Verminous broncho pneumonia
⚫Lung worm infestation is an enzootic or epizootic
affection manifested by bronchitis & bronchopneumonia
& caused by infestationof lung by metastrongylides
14. Etiology
⚫Dictycaulus filarial of sheep, goat, camel &
occasionallycattle.
⚫Dictycaulus viviparous of cattle.
⚫Dictycaulus oviparous of horse & donkey.
⚫Metastrongylus elongatus of pigs & occasionally in
sheep.
⚫Prostrongylus rufescens: sheep, goat & rabbit.
⚫Prostrongylus commintatus: sheepand goat.
⚫Mallerious coppillaris: sheep & lambs.
⚫Strongylus abstruses: cat.
⚫Haemostrongylus vasorum: dog.
15. Clinical findings
⚫Cough.
⚫Nasal discharge.
⚫Respiration is labored.
⚫Severeriseof body temperaturereaching to 42 when
the lung is involved.
⚫Emaciation.
⚫Anaemia.
⚫Frequentdiarrhea.
⚫Enlargement & swelling of submaxillanyregion, lips &
eye lids
16. Treatment
