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.

Mycoplasmas cause some of the most economically important diseases of sheep and goats, including diseases listed by the World Organisation for Animal Health (OIE) such as contagious caprine pleuropneumonia (CCPP) and contagious agalactia (CA). Other important mycoplasma diseases include chronic respiratory and arthritic syndrome (CRAS) and atypical pneumonia, both present on all continents where small ruminants are farmed. Unfortunately, owing to a lack of investment, most commercial vaccines for these diseases are of poor quality, being mostly composed of killed bacteriocins of dubious or unknown efficacy. Several Mediterranean laboratories produce autogenous vaccines, but these can only be used on farms where outbreaks have been officially declared, and consequently have limited impact on disease nationally. Effective live vaccines are available, but their use is often restricted because of safety concerns. With the necessary safeguards in place, we argue for their greater use. This review examines reported vaccines for mycoplasma diseases of small ruminants and attempts to identify new candidate antigens that may enable the development of improved products. Vaccines for CCPP are covered elsewhere.

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.

Peste des petits ruminants (PPR) is a highly contagious disease of small ruminants that leads to high morbidity and mortality, and thereby results in devastating economic consequences to the livestock industry. It is caused by the PPR virus (PPRV), which belongs to the genus Morbilivirus in the family Paramyxoviridae. PPR was first recorded in early 1942 in Ivory Coast, West Africa. In the following years, the disease extended its distribution to other parts of the world and now circulates throughout Northern, Eastern and West Africa, as well as Asia – in particular, China, Central Asia, Eurasia, the Indian subcontinent and the Middle East. The molecular epidemiology of PPRV, based on the sequence comparison of a small region of either the N or the F gene, has revealed the existence of four distinct lineages (I-IV) of the virus. Until June 2018, PPR had never been detected in Europe, with the exception of the European part of Turkish Thrace. However, on 24th June 2018 the Bulgarian authorities reported cases of PPR in sheep in the village of Voden, Bolyarovo municipality of Yambol region, on the border with the Thrace region of Turkey. It was the first occurrence of PPR in Bulgaria and in the European Union (EU). The source of PPR infection in Bulgaria is not clear, it could have been the illegal movement of animals, contaminated materials or humans, e.g. refuges. Due to the increased risk of introduction of PPR from North Africa and Turkey to neighbouring regions, the European Food Safety Authority (EFSA) has recently published a report assessing the risk of PPR spreading in Europe. According to a scientific opinion by the EFSA, the spread of PPRV in the territory of the UE could occur by the illegal transport of infected animals or infected animal products. In order to limit the spread and impact of PPR outbreaks in Europe, rapid detection, movement restriction, prompt culling of infected herds and disinfection measures should be introduced immediately. The control and eventual eradication of PPR is now one of the top priorities for the Food and Agriculture Organization (FAO) and the World Organization for Animal Health (OIE). In 2015, the international community agreed on a global strategy for PPR eradication, setting 2030 as a target date for elimination of the disease.

Bluetongue is non contagious vector borne viral disease of small ruminants. It transmits by biting of culicoids midges and causes severe economic losses to animal owner in term of high morbidity, decreased production and impaired reproduction. Balochistan, being largest province of the country have scattered population in far remote areas. About 70% of the provincial population rely upon livestock rearing for their livelihood. Kalat is largest division of the province that stretches from Kalat city upto Lasbella including Khuzdar, Kharan and Awaran. It is located on main RCD route that will ultimately boost the animal marketing and their easy access to main market. Although different vaccines are practiced throughout the province but no such vaccine is available against BTV in the country. That’s why animals are facing problems of some undiagnosed diseases. This review provides necessary information about disease in the region. It is need of the time to educate farmer and strict vigilance may be practiced for proper and timely vaccination of all animals to curtail deadliest diseases in the region.

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.

AbstractSmall ruminants represent an important economic source in small farm systems and agriculture. Feed is the main component of livestock farming, which has gained special attention to improve animal performance. Many studies have been done to improve feed utilisation through addition of feed additives. For a long period, antibiotics have been widely used as growth promoters in livestock diets. Due to their ban in many countries, search for alternative feed additives has been intensified. Probiotics are one of these alternatives recognised to be safe to the animals. Use of probiotics in small ruminant nutrition has been confirmed to improve animal health, productivity and immunity. Probiotics improved growth performance through enhancing of rumen microbial ecosystem, nutrient digestibility and feed conversion rate. Moreover, probiotics have been reported to stabilise rumen pH, increase volatile fatty acids production and to stimulate lactic acid utilising protozoa, resulting in a highly efficient rumen function. Furthermore, use of probiotics has been found to increase milk production and can reduce incidence of neonatal diarrhea and mortality. However, actual mechanisms through which probiotics exert these functions are not known. Since research on application of probiotics in small ruminants is scarce, the present review attempts to discuss the potential roles of this class of feed additives on productive performance and health status of these animals.

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.

The proper diagnosis of gastrointestinal parasites of small ruminants requires the development of multivalent techniques characterized by high sensitivity, specificity, precision, reproducibility, and the ability to quickly detect and monitor infections that pose risks to animal health. The aim of this study was to evaluate the performance of Mini-FLOTAC technique and McMaster egg counting (gold standard) in the detection of gastrointestinal parasites of goats and sheep. A total of 789 fecal samples were analyzed (401 of sheep and 388 of goats). From those, nematode eggs were detected in 80.86% (638/789), being 72.57% (291/401) from sheep and 89.43% (347/388) from goats. The Mini-FLOTAC technique presented a better performance to detect helminth eggs in both goats (88.40%; 343/388) and sheep (71.57%; 287/401) (?2 = 10.358; p < 0.0001). Kappa analysis revealed a weak concordance between techniques for goats (k = 0.342; p < 0.001) and sheep (k = 0.281; p < 0.001). Data herein reported suggests that the Mini-FLOTAC is a technique more sensitive than the McMaster egg counting, therefore its use might be adopted for the diagnosis of gastrointestinal infection in small ruminants.

Peste des petits ruminants (PPR) is a highly contagious and economically important, viral disease of small ruminants caused by the peste des petits ruminants virus (PPRV), which belongs to the genus Morbilivirus in the family Paramyxoviridae. PPR control is achieved mostly through vaccination and/or slaughter of susceptible animals coupled with clinical or laboratory-based diagnosis. Since clinical signs of PPR are not disease-specific and clinical diagnostics is not reliable, it should be confirmed by laboratory testing. Laboratory confirmation of clinical suspicions is made by detection of PPRV in blood, swabs or post-mortem tissues through classical virus isolation (VI), agar gel immunodiffusion (AGID)/agar gel precipitation test (AGPT), counter-immunoelectrophoresis (CIE), immunoperoxidase test (IPT) or enzyme-linked immunosorbent (ELISA) assays. However, these conventional methods have been superseded by more rapid, sensitive and accurate molecular diagnostic techniques based on the amplification of parts of either nucleocapsid (N) or fusion (F) protein gene, such as RT-PCR, real-time RT-PCR, reverse transcription loop-mediated isothermal amplification (RT-LAMP), reverse transcription recombinase polymerase amplification (RT-RPA) and Oxford nanopore MinION technology. Although these molecular diagnostic assays are accurate, rapid and sensitive, they have to be performed in laboratory settings, and samples must be transported under appropriate conditions from the field to the laboratory, which can delay the confirmation of PPRV infection. The recently developed immunochromatographic lateral flow device (IC-LFD) assay can be used in the field (“pen-side”) without the need for expensive equipment, so a well-established laboratory is not required. The control and eventual eradication of PPR is now one of the top priorities for the Food and Agriculture Organization (FAO) and the World Organization for Animal Health (OIE). In 2015, the international community agreed on a global strategy for PPR eradication, setting 2030 as a target date for elimination of the disease
