“…Furthermore, the present studies have also revealed the evidence of isolation of Mycoplasma capricolum subsp capripneumonae (Mccp), the causative agent of contagious caprine pleouro pneuminiae (CCPP) among the goat population in the study area, previous studies had [12,13]. this however, led to the assertion that Mccp might have been long existed in the area, since the introduction of new flocks was not a common practice among the farmers, there is high tendency to incriminate the uncontrolled animal movement between northern Cameroon and the neighboring countries in the east and west, particularly with those in the east Africa where CCPP is common.…”

“…One of the major constraints to increase small ruminants production in Africa has been the occurrence of infectious diseases and poor management practiced in most parts of the continent [7][8][9][10][11]. Among such diseases is the occurrence of Pasteurellosis and Mycoplasmosis [3,8,[12][13][14][15]. Peste des petits ruminants (PPR) is also known as 'goat plague', 'Kata', 'syndrome of stomatitis-pneumoenteritis'.…”

The role of husbandry practice and incidence of respiratory pathogens (Mycoplasma capricolum subsp. capripneumoniae [Mccp], Pasteurella multocida [MP] and Peste des petits ruminant virus [PPRV]) were investigated among 13 flocks consisting of 300 goats and 200 sheep in the Northern Cameroon. The variables investigated were introduction of new stock into flock, morbidity, mortality, destocking, routine tissue culture rinderpest vaccine (TCRV) vaccination and rearing of small ruminants with other animals species. Introduction of new stock was not commonly practiced by flock owners and animals in the flocks received routine TCRV vaccination. Slaughtering and sale of sick animals were the commonest means of destocking. These correlated positively with morbidity and mortality rates in all the flocks investigated. Attempts at recovery of respiratory pathogens from nasal swabs of the experimental animals revealed the following isolates: Mycoplasma (small colony) from 27% of goats and 0% of sheep; MP from 18% of goats and 5% of sheep; Mycoplasma (large colony) from 6% of goats and 10% of sheep. None of the swabs shows peste des petit ruminants virus (PPRV) isolate. The difference in the pathogen recovery rate between sheep and goat was significant. It has correlated positively with the occurrence of respiratory symptoms, morbidity and mortality in most of the flocks and locations studied. The occurrence of respiratory pathogens observed in the present studies may be an important factor in the production of small ruminants in northern Cameroon. This study has provided preliminary data for further investigation into the definite role of these respiratory infections of small ruminant in northern Cameroon. We therefore suggest the need to embark on a mass vaccination program campaign against this pathogen, and the need for strict control of animal movement to and from the neighboring countries and a periodic surveillance for respiratory pathogens be incorporated into a national program for the prevention and control measures against this endemic pathogen.

“…In addition, analysis of specimens collected from slaughtered animal during routine examination at Garoua abattoir (in the north-province) yielded several respiratory pathogens including Mycoplasmascapricolum (Mcc), Pasteurella multocida and PPRV [15][16][17]. Mycoplasmas was reported to have been the major cause of economic losses in goat population in at least 30 countries in Africa and Asia containing a total goat population of more than 300 million [18,19].…”

“…Mycoplasma mycoides subsp capri (Mmc) mainly causes mastitis, arthritis, keratitis, pneumonia and septicaemia in goats (Thiaucourt and Bolske, 1996), which threaten a great number of goat populations throughout the world, with a high impact in Asia, Africa, and the Middle East (MacOwan and Minette, 1976;Ojo, 1976;Villalba et al, 1992;Martrenchar et al, 1995). In China, the diseases are prevalent in flocks in Guizhou province and Guangxi zhuang autonomous region, resulting in major economic losses (Wan et al, 2001;Zou et al, 2007).…”

ABSTRACT. Mycoplasma mycoides subsp capri is the cause of goat "MAKePS" (Mastitis, Arthritis, Keratoconjunctivitis, Pneumonia, Septicemia) syndrome. We identified three genes (GL_ 000459; 000461; 000462) as variable lipoprotein genes in the M. mycoides subsp capri str. PG3 genome by genomic information and comparative genomic analyses. To study the role of variable lipoproteins in M. mycoides subsp capri pathogenesis and evaluate the immunogenic and protective potentials of those proteins, we constructed the expression systems and expressed the mature peptide portion of the three proteins in E. coli. We also determined the titers and opsonophagocytosis activity of total IgG antibodies and the levels of Th1 and Th2 cytokines in sera, and we ran a lymphocyte proliferation assay in mice immunized with recombinant proteins His-tag-GL000459, His-tag-GL000461, and His-tag-GL000462. These three lipoproteins induced humoral and cellular immune responses in the immunized mice. Additionally, the whole blood opsonophagocitic in vitro assay demonstrated that the antibodies produced by the immunized groups can neutralize strain PG3; consequently, these three variable lipoproteins could be the major surface antigens in M. mycoides subsp capri str. PG3.
