This is contagious disease of goat having resemblance with contagious bovine pleuropneumonia.
Distribution
The disease is wide spread in tropical countries. In India, the disease is reported from Chennai, Assam, Mumbai, Haryana, Uttar Pradesh, Bihar, West Bengal.
Aetiology
Mycoplasma mycoides sub species caprae is the causative organism of this disease. Other mycoplasma like M. mycoides sub species mycoides. M. agalactiae, M. arginini and M. capricola have also been seen to cause pathological changes. M. mycoides sub species mycoides has been considered as the principal cause of pleuropneumonia in kids upto 6 months.
Mode of Transmission
The infection is spread through inhalation. The organisms do not live long outside the animal’s body. Bot fly has been found to spread the infection. Experimental transmission is possible.
Clinical Findings
This is a highly fatal disease of sheep and goat. Mortality varies from 60 to 100%. The incubation period is about 4 days. The signs are comprised of anorexia, dullness, depression, nasal discharge, abdominal respiration, fever and dry painful cough. Animal may die having no pathological changes in the lungs.

The clinical lesions and patterns are almost similar to cattle except that a sequestrum is not formed.
Lesions
On post-mortem examination, congestion and consolidation of lungs, thickening of inter lobular septa and necrosis of pleura is noted.
Diagnosis
Methods are more less similar to CBPP. Blood picture shows decrease RBC and haemoglobin and increase serum glucose and urea nitrogen. CFT and ELISA can be made to detect carrier animal PCR may be used. it has to be differentiated from PPR, HS, contagious agalactia and MAMEPs.
Treatment
This can be treated with oxytetracycline, rolitetracycline, chloramphenicol and Tylosin. Tylosin @ 40 mg/kg for 5 days and Tiamulin @ 36 mg/kg gave satisfactory response. Treatment with Tylosin tartrate @ 10 mg/kg intramuscularly along with cotrimoxazole tablet for 5-7 days have been suggested. Treatment with alincomycin gave satisfactory result.
Control
Vaccine may be used. The vaccine consists of live culture of M. caprae. Dose 0.2 ml to be given at the tip of the ear. Saponin killed lyophilized vaccine can be used. Revaccination at 6 month interval is recommended.
