“…All these tests are either based on the growth and metabolic characteristics of Mccp, for example, ability to ferment glucose, digest casein and serum, reduce tetrazolium (Adehan et al. 2006; Soayfane et al. 2018) or to its immunogenic potential, for example, surface antigens which are glycolipids and proteins, as detected by CFT and ELISA, respectively (OIE 2014; Peyraud et al.…”

“…Adehan et al. (2006) noted that Mccp hydrolysed glucose, reduced tetrazolium chloride, and weakly digested serum. Recently, based on oxygen uptake rates, Mccp have been divided into two major biochemical groups, namely organic acid-oxidizing group that metabolise oxidised organic acids and glycerol and the glucose-oxiding group that metabolises sugars (Soayfane et al.…”

Contagious caprine pleuropneumonia (CCPP) is a serious disease of goats, occasionally sheep and wild ruminants, caused by Mycoplasma capricolum subspecies capripneumoniae (Mccp). The disease is characterized by severe serofibrinous pleuropneumonia, very high morbidity ($100%), and mortality (80-100%). CCPP affects goats in more than 40 countries of the world thereby posing a serious threat to goat farming around the globe. The characteristic clinical signs of CCPP are severe respiratory distress associated with sero-mucoid nasal discharge, coughing, dyspnea, pyrexia, pleurodynia, and general malaise. In later stages, severe lobar fibrinous pleuropneumonia, profuse fluid accumulation in pleural cavity, severe congestion of lungs and adhesion formation is observed. Mycoplasmal antigen interactions with host immune system and its role in CCPP pathogenesis are not clearly understood. CCPP is not a zoonotic disease. Diagnosis has overcome cumbersome and lengthy conventional tests involving culture, isolation, and identification by advanced serological (LAT, cELISA) or gene-based amplification of DNA (PCR, RFLP, and hybridization) and sequencing. The latex agglutination test (LAT) is rapid, simple, and better test for field and real-time diagnosis applicable to whole blood or serum and is more sensitive than the CFT and easier than the cELISA. Moreover, the studies on antibiotic sensitivity and exploration of novel antibiotics (fluoroquinolones, macrolides) can help in better therapeutic management besides preventing menace of antibiotic resistance. Re-visiting conventional prophylactic measures focussing on developing novel strain-based or recombinant vaccines using specific antigens (capsular or cellular) should be the most important strategy for controlling the disease worldwide.

“…Mycoplasma infections cause indirect economic losses as a result of emaciation, delayed market weight, and infertility, owing to the sub-acute or chronic pneumonia, especially in small ruminants, which are of great importance in rural development. A major health problem of small ruminants is pneumonia/ pleuropneumonia, which may be caused by Mycoplasma species alone or in conjunction with other microbes (Adehan et al, 2006). The isolation of these bacterial species is time-consuming and requires different media and laboratory conditions.…”

Respiratory infections of sheep and goats cause heavy morbidity and mortality, leading to huge economic losses. Conventional methods of diagnosis that include isolation and identification of incriminating microbes are time-consuming and fraught with logistic challenges. Direct detection of incriminating microbes using molecular tools is gaining popularity in clinical, microbiological settings. In this study, a total of 50 samples (44 nasal swabs and 6 lung tissues) from sheep and goats were screened for the detection of different bacterial species by in vitro amplification of genus or species-specific genes. Histophilus somni was detected in 2% goat samples, Trueperella pyogenes in 20% goat nasal swabs, whereas 22% goat nasal swab samples were found positive for Mycoplasma spp. None of the samples from sheep was detected positive for H. somni, T. pyogenes, Mycoplasma spp. Similarly, all samples, irrespective, whether from sheep or goats, showed negative results for Pasteurella multocida, Mannheimia haemolytica, and Corynebacterium pseudotuberculosis.

“…As micoplasmoses em caprinos são amplamente disseminadas pelo mundo (ADEHAN et al, 2006) e representam um grande problema socioeconômico, principalmente em regiões que dependem desses animais como fonte renda (RAZIN, 2002). Devido à cultura dos criadores nordestinos na participação em feiras e exposições, a troca de animais reprodutores entre os produtores menores e a rápida disseminação desses micro-organismos (BANDEIRA et al, 2008), associada à falha na detecção, proporciona a expressiva propagação das micoplasmoses por todo rebanho caprino nordestino (CÂMARA, SILVA e GUERRA, 2015).…”

“…Os micoplasmas podem ser responsáveis por afecções em sistema respiratório (pleuropneumonia e pneumonia), mastite, artrite e poliartrite, doenças genitais e lesões oculares (conjuntivite e cerato-conjuntivite) (NICHOLAS, 2002;GREGORY et al, 2003;ADEHAN et al, 2006;RAZIN & HAYFLICK, 2010 (CONTRERAS, 2003;AZEVEDO, 2005;AZEVEDO et al 2006;CORRALES, 2007;OIE, 2014;KUMAR et al 2014;SANTOS et al 2015).…”
