Slide 3: 

Introduction Sheep and goat pox are contagious viral diseases of small ruminants. These diseases may be mild in indigenous breeds living in endemic areas, but are often fatal in newly introduced animals.

Slide 4: 

Etiology: Sheep pox and goat pox result from infection by sheeppox virus (SPV) or goat-pox virus (GPV), closely related members of the Capripox genus in the family Pox-viridae. Most isolates are host specific, with SPV mainly causing disease in sheep and GPV predominantly affecting goats.

Slide 5: 

Epidemiology: Mainly susceptible host are cow horse, sheep, goats, buffaloes, swine, fowl as well as human beings also. Worldwide distribution. Sheep and goat pox is highly contagious and enzootic prevalent in north and central Africa, India, Bangladesh and middle eastern countries, china.

Slide 6: 

Clinical Signs Papulove-sicular form of the disease, the centers of the papules become depressed, whitish gray and necrotic. Nodules can be found in the epidermis, dermis and subcutaneous tissues. All superficial lymph nodes usually become enlarged. Lesions in the mouth, nares , eyes or eyelids can cause salivation or inappetence , as well as rhinitis, conjunctivitis or blepharitis with mucopurulent discharges.

Slide 8: 

Mode of Transmission SPV and GPV are often transmitted by the respiratory route during close contact, but they may also enter the body through other mucous membranes or abraded skin. These viruses can be found in saliva, nasal and conjunctival secretions, milk, urine and feces, as well as in skin lesions and their scabs. Ulcers on the mucous membranes are important sources of virus.

Slide 9: 

Incubation Period The incubation period varies from four to 21 days, but it is usually 1 to 2 weeks.

Slide 10: 

Diagnosis Clinical sign consists of skin lesion Dyspnea, conjunctivitis, nasal discharges and other signs may also be seen. A persistent fever Mortality may approach 50% in adult and 95% in lambs and kids Lymphadenitis and often pneumonia A persistent fever

Slide 11: 

Laboratory diagnosis Sample collection:Skin biopsies Necropsy specimens:Skin trachea lung lymph node Buffy coat from blood collected into heparin or EDTA can also be used Agar gel precipitation test using lymph node biopsy

Slide 12: 

Differntial diagnosis: contagious ec-thyma Bluetongue, Der-matophilosis, Mange Photosensitization, Peste des petits in ruminants.

Slide 13: 

Treatment Whitefield`s ointment and 10% sulphathiazole ointment Antibiotic ointment Gentacin ® -Square, (0.1% Gentacin , 5gm tube) Nebanol ® -Square,(Neomycin & Bacitracin , 10gm tube) Neotracin ® -Acme, ,(Neomycin & Bacitracin , 10gm tube)

Slide 14: 

Prevention and control Quarantine and examine newly purchased animal for 14days before introduction to the milking herd Isolate infected animals Minimize risk of disease transmission by fliesRestriction on movement of animal products-meat, hair, wool and hides. Vaccination strategy.

Slide 15: 

CONCLUSION Sheep and goat pox can limit trade and prevent the development of intensive livestock production. Economic losses result from decreased milk production, damage to the quality of hides and wool, and other production losses
