| detection of mycoplasmas in goat milk by flow cytometry. | the detection of mycoplasma in milk can be performed by either culture techniques or polymerase chain reaction (pcr) based methods. although pcr can reduce the average diagnostic time to 5 h in comparison with the several days for the isolation of the agent, there is still a need to develop methods, which could give earlier results. for this purpose, we tested the ability of flow cytometry (fc) to detect mycoplasmas in milk samples. milk samples inoculated with four different mycoplasmas, mycopl ... | 2007 | 17972304 |
| in vitro antimycoplasmal activity of six jordanian medicinal plants against three mycoplasma species. | the in vitro effect of six jordanian traditional medicine plant methanolic extracts were tested against 32 isolates of mycoplasma species; mycoplasma mycoides subsp. mycoides lc (6), mycoplasma capricolum subsp. capricolum (8) and m. putrefaciens (18), all isolated from either nasal swabs or milk, from sheep and goats in different regions in jordan. all mycoplasma species showed susceptibility to artemisia herba-alba and artemisia arborescens with mic ranges from 3.125-12.5 mg/ml. allium sativum ... | 2007 | 17969714 |
| a pcr for the detection of mycoplasmas belonging to the mycoplasma mycoides cluster: application to the diagnosis of contagious agalactia. | contagious agalactia is a mycoplasmal infection caused by mycoplasma agalactiae, mycoplasma mycoides subsp. mycoides lc, m. mycoides subsp. capri, mycoplasma capricolum subsp. capricolum and mycoplasma putrefaciens. identification of the causative organisms is usually performed by isolation and classical biochemical and serological tests, though this is a lengthy and cumbersome process for mycoplasmas. specific pcr assays have been developed for the identification of mycoplasma agalactiae and m. ... | 2007 | 17606362 |
| experimental infection of goats with an unusual strain of mycoplasma mycoides subsp. capri isolated in jordan. | goats were infected experimentally with a mycoplasma (the "irbid" strain) isolated previously from a goat with contagious agalactia in northern jordan. the strain was unusual in that, although it had been identified by molecular methods as mycoplasma mycoides subsp. mycoides lc/mycoplasma mycoides subsp. capri, it showed no inhibition of growth by any of the hyperimmune rabbit antisera conventionally used to speciate members of the mycoplasma mycoides cluster. animals were infected either intrat ... | 2009 | 19446837 |
| mycoplasma leachii sp. nov. as a new species designation for mycoplasma sp. bovine group 7 of leach, and reclassification of mycoplasma mycoides subsp. mycoides lc as a serovar of mycoplasma mycoides subsp. capri. | the mycoplasma mycoides cluster consists of six pathogenic mycoplasmas causing disease in ruminants, which share many genotypic and phenotypic traits. the m. mycoides cluster comprises five recognized taxa: mycoplasma mycoides subsp. mycoides small colony (mmmsc), m. mycoides subsp. mycoides large colony (mmmlc), m. mycoides subsp. capri (mmc), mycoplasma capricolum subsp. capricolum (mcc) and m. capricolum subsp. capripneumoniae (mccp). the group of strains known as mycoplasma sp. bovine group ... | 2009 | 19502315 |
| kinetics of substrate oxidation and hydrogen peroxide production by mycoplasma mycoides subsp. mycoides large colony (lc) type and mycoplasma mycoides subsp. capri. | mycoplasma mycoides subsp. mycoides large colony (lc) type is a pathogen of goats causing contagious agalactia and respiratory disease, found on all continents where small ruminants are kept. it shares close genetic characteristics with m. mycoides subsp. capri. substrate oxidation by 22 strains of m. mycoides subsp. mycoides lc from nine countries was compared with that of eight strains of m. mycoides subsp. capri from five countries. there was considerable similarity in the substrates used, bu ... | 2009 | 19457526 |
| strains of mycoplasma mycoides subsp. mycoides small colony type isolated in china between 1953 and 1960 show close similarity to strains of the africa/australia cluster. | in this study, six chinese strains of mycoplasma mycoides subsp. mycoides small colony type (mmmsc) isolated between 1953-1960 were analysed and their molecular characteristics compared to those of the african pg1 and afade strains, the european c305 and 138/5 strains and the closely related caprine m. mycoides subsp.mycoides large colony type y-goat strain. pcr amplification of long dna fragments showed that the six chinese strains, the pg1 strain and the y-goat strain, just like afade, did not ... | 2009 | 17936044 |
| effects on goat milk quality of the presence of mycoplasma spp. in herds without symptoms of contagious agalactia. | this study was designed to assess the possible effects of mycoplasmas on the quality of milk produced by goat herds in a contagious agalactia (ca) endemic area with absence of classical symptoms. several factors related to milk quality (percentages of fat, total protein, lactose and total solids, standard plate counts (spc) and presence of staphylococcus aureus) were compared in mycoplasma-infected and non-infected herds. to define the ca status of 26 herds on the island of lanzarote (spain), wh ... | 2009 | 18922196 |
| extended surveillance for cbpp in a free country: challenges and solutions regarding the potential caprine reservoir. | contagious bovine pleuropneumonia (cbpp) is a severe respiratory disease of cattle and buffalo caused by mycoplasma mycoides subsp. mycoides "small colony" (mmmsc). the agent of cbpp has been isolated from goats in different countries including cbpp-free areas. goats can therefore be regarded as a putative mmmsc reservoir. no diagnostic test for cbpp surveillance in goats has been proposed as yet. furthermore, serological tests could be seriously hampered by a widespread caprine infection due to ... | 2011 | 21620492 |
