Cluster A

Contagious caprine pleuropneumonia (CCPP) is caused by Mycoplasma capricolum subsp. capripneumoniae (Mccp) which belongs to the Mycoplasma mycoides cluster, a group of five closely related Mycoplasmas, pathogenic to ruminants. The true lesions of CCPP are restricted to the alveolar tissues of infected goats, which distinguish it from other respiratory diseases of small ruminants caused by members of the Mycoplasma mycoides cluster. The typical signs of CCPP are an accumulation of pleural fluid, unilateral hepatisation, adhesions, pleurisy and pleuropneumonia which clearly differentiate it from “MAKePS” syndrome caused by Mycoplasma mycoides subsp. capri (Mmc). The available literature on CCPP shows that so far in Pakistan, the true causative agent (Mccp) of this disease has only been isolated in the Pashin District of Balochistan and that the disease is more frequently confused with other respiratory diseases of goat caused by the Mycoplasma mycoides cluster. The lack of suitable techniques and extensive knowledge in the field is a big limitation for the isolation and characterisation of Mccp from prevailing CCPP-like cases in the goat population of Pakistan.

Contagious agalactia (CA) is suspected when small ruminants show all or several of the following clinical signs: mastitis, arthritis, keratoconjunctivitis and occasionally abortion. It is confirmed following mycoplasma isolation or detection. The historical and major cause is Mycoplasma agalactiae which was first isolated from sheep in 1923. Over the last thirty years, three other mycoplasmas (Mycoplasma mycoides subsp. capri, Mycoplasma capricolum subsp. capricolum and Mycoplasma putrefaciens) have been added to the etiology of CA because they can occasionally cause clinically similar outcomes though nearly always in goats. However, only M. agalactiae is subject to animal disease regulations nationally and internationally. Consequently, it makes little sense to list mycoplasmas other than M. agalactiae as causes of the OIE-listed CA when they are not officially reported by the veterinary authorities and unlikely to be so in the future. Indeed, encouraging countries just to report M. agalactiae may bring about a better understanding of the importance of CA. In conclusion, we recommend that CA should only be diagnosed and confirmed when M. agalactiae is detected either by isolation or molecular methods, and that the other three mycoplasmas be removed from the OIE Manual of Diagnostic Tests and Vaccines in Terrestrial Animals and associated sources.

Contagious Caprine Pleuropneumonia

Mycoplasma infection of the respiratory tract of goats is prevalent worldwide including the South Asian sub-continent. Owing to intensive and large scale goat farming, the incidence of the disease is on an increase. Among various species of mycoplasma, Mycoplasma capricolum subspecies Capri pneumoniae is increasingly incriminated in Contagious Caprine Pleurapneumonia (CCPP) in goat populations with considerable economic fallout in the form of high morbidity and mortality. The disease manifestations in caprines are recorded as anorexia, high febrile reaction and respiratory embarrassment in the shape of clinical dyspnoea, polypnea, paroxysmal cough and sero-purulent nasal discharges. The disease is thus contracted by the healthy animals through aerosol, contaminated feed and water sources in the herd premises, without a protective immunity and that the conferred immunity in recovered cases being short-lived. The true lesions of CCPP are confined to the lung alveolar tissues of infected goats, which distinguish it from other respiratory diseases of small ruminants caused by the members of the Mycoplasma mycoides cluster. Atypical pneumonia caused by the mycoplasma infection of goats, also known as Contagious Caprine Pleuropneumonia (CCPP) has been more often reported from Africa and Asia than Europe. Classical, acute CCPP attributed to Mycoplasma capricolum subsp. Capri pneumoniae, originally known asthe F38 biotype (World Organisation for Animal Health, 2008) causes heavy kid mortality. Two other organisms in this group, M. mycoides subsp. capri and M. mycoides subsp. mycoides large-colony type, can cause disease in small ruminants that clinico-pathologically mimics CCPP but may have extra pulmonary signs and lesions, sometimes. Mycoplasma Capri pneumoniae and other members of the M. mycoides cluster cross-react in serological tests and share biochemical and genetic similarities. The most favourable epidemiological scenario in the Sub-continent is the hot humid climate during monsoons. The diversity and multi-etiological subspecies involved in the disease is detrimental in the development of an effective vaccine even though in some places a liquid vaccine is presently in use. At other places, anti-mycoplasmal antibiotics of aminoglycoside and fluoroquinolone and perhaps the macrolide groups remain to be the main option in preventing flock mortalities.

Goat rearing has emerged as a significant resource in rural areas even under unfavorable environmental conditions. Goat population in India has grown over the past few decades and stands at 148.88 million during 2019 (Census, 2019) owing to their greater socio-economic relevance. Goats, while being generally resistant to diseases, are highly susceptible to respiratory diseases, which account for almost 50% mortality amongst them. Irrespective of the etiology, the infectious respiratory diseases of sheep and goats contribute to 5.6% of the total diseases of small ruminants and is responsible for around 28.7 % mortality. Pneumonia has been noticed as one of the most frequently encountered condition and is responsible for around 28.7% mortality. Amongst various infections, Mycoplasmosis is one of the most dreaded diseases of goats. The present study was undertaken to detect the Mycoplasma capri infection in cauvery delta region of Tamil Nadu. All the collected tissue materials were subjected to isolation and PCR assay with Mycoplasma group specific primers (GPO- 1 and MGSO) which yielded 715 bp product and Mycoplasma capri specific primers (P 4 and P 6) which gave an amplicons of 195 bp products. The findings indicate that the PCR assay is very simple and useful method for detecting the mycoplasma infection directly from the tissue materials in a very short span.

Background: Contagious caprine pleuropneumonia (CCPP), caused by Mycoplasma capricolum subsp. Capripneumoniae (Mccp), is one of the most important goat diseases causing high morbidity and mortality, these results in heavy economic losses to countries like Somalia, which is a country affected the civil war of the 1990s. Objective: Generally, the disease presence has been reported in the country. However, there is no quantitative data on the prevalence and distribution of the disease has been scientifically reported in the country. Methods: A cross-sectional study was conducted from September 2019 to June 2020 in three villages of Afgoye district of Somalia to assess the seroprevalence and identify the associated risk factors for the occurrence of the CCPP. The risk factors considered included sex, age, and locations. Results: A total of 100 blood samples were collected and evaluated by Capri-Latex Agglutination Test (Capri-LAT). A total of 49/100 (49%, CI 95%: (38.86%-59.2%) goats were seropositive for anti-CCPP antibody. The epidemiological risk factors considered, sex, age and locations, were not significantly associated with the CCPP sero prevalence (p>0.05). However, the sero positivity was slightly higher in female (51%, 95% CI: 39.8-62.6), >3 years old goats (86.3%, 95% CI: 48.9-87.4) and Markazka village (56%, 95% CI: 41.3-70.0) compared to male (40%, 95% CI: 19.1-63.9), 1-3 years old (57.5%, 95% CI: 40.9- 73.0), and Shareeco (43.8%, 95% CI: 19.8-70.1) and Siinka (41.2%, 95% CI: 24.7-59.3) villages, respectively. Conclusion: The present study indicates the prevalence of CCPP in the studies areas and this requires practicable measures to be put in place towards the control of the disease.

Foot And Mouth

Background: Foot-and-Mouth Disease (FMD) remains a serious threat to the Indian livestock sector due to significant economic loss associated with it. Systematic vaccination of large ruminants over the years has lead to a gradual reduction in the number of disease outbreaks in India. However exposure to FMDV infection in small ruminants has been recorded during the past few years (Rout et al. 2013). Sheep and goat population have not been vaccinated so far against FMD under the FMD-Control program (FMD-CP). The present study highlighted the outbreak of FMD in small ruminants in Karnataka, India.Methods: During the period 2018-19, seven suspected FMD outbreaks among sheep population in Bellary and Tumakuru districts of Karnataka state were investigated. Tongue epithelium (oral swabs) and foot lesions (n=23) from clinically affected sheep and tissues such as heart, lung, liver, spleen, lymph nodes and kidneys from lambs during post mortem (n=67) were collected. All the samples were processed in the laboratory for the detection of FMD virus antigen by employing Serotype differentiating antigen detection ELISA and by multiplex PCR. Heart tissue samples were also collected in buffered formalin for histopathology study and processed by routine paraffin embedding technique and stained with Hematoxylin and Eosin (H and E). Serum samples from the recovered animals were collected and screened by NSP-ELISA and LPB-ELISA to check the antibody status in the affected herd. Result: A total of seven suspected outbreaks of FMD involving 688 small ruminants was investigated. The outbreak of FMD due to FMDV serotype O was confirmed by ELISA and multiplex PCR assays. Clinically, the affected adult sheep showed typical signs of FMD, while mortality in young lambs was observed without apparent signs of disease. Histologically, heart tissues from FMD affected lambs showed myocardial necrosis with marked aggregations of lymphocytes and neutrophils in the myocardium and perivascular spaces. History of FMD outbreaks in cattle and common grazing land for the livestock, as well as sheep within the reach of these villages, may be the major contributing factors for the outbreaks in sheep populations.
