| ageing-related changes in mycoplasma canadense membranes. | fluidity and composition of cell membranes during progression of mycoplasma canadense cultures grown in a serum-free medium was assessed. the fluorescence anisotropy of 1,6-diphenyl-1,3,5-hexatriene at 25 degrees c of intact cells and liposomes in the exponential and stationary phases of growth was compared. a decrease in fluidity and an increase in the ratio of saturated to unsaturated fatty acids was detected in cell membranes on aging. nevertheless, membrane density remained unaltered althoug ... | 1992 | 1541600 |
| conditions for growing mycoplasma canadense and mycoplasma verecundum in a serum-free medium. | mycoplasma canadense and mycoplasma verecundum were cultured in a serum-free medium containing bovine serum albumin, cholesterol, oleic acid, and palmitic acid in order to avoid the addition of horse serum. growth was detected by measurement of a640 and by colony formation. the level of growth attained in this medium was less than that obtained in the horse serum-supplemented media, but colonies retained their distinctive morphology. | 1990 | 2202260 |
| an outbreak of granulomatous vulvitis in feedlot heifers. | an unusual form of vulvitis occurred in outbreak form affecting at least 18 of a group of 35 to 40 heifers soon after their introduction to a feedlot in the western transvaal area of the republic of south africa. initially, affected animals showed a knob-like swelling of the ventral commissure of the vulva. this grew in size up to approximately 6 cm in diameter and then appeared to burst open and give rise to a granulomatous lesion. bovine herpesvirus type-1, moraxella bovis, mycoplasma bovigeni ... | 1990 | 2269990 |

| studies on inactivation of pathogenic microorganisms in culture media and in bovine semen by photosensitive agents. | the application of three photosensitive agents for disinfection of bovine semen was investigated. bovine microbial pathogens suspended in tissue culture medium and/or pbs and also added to bovine semen were exposed to the photosensitive agents followed by irradiation. hematoporphyrin, hematoporphyrin derivative and thiopyronine were effective against bovine herpes virus-1, bovine viral diarrhoea virus, mycoplasma bovigenitalium, mycoplasma canadense, and ureaplasma diversum in culture media. in ... | 1994 | 8017031 |
| phylogeny of some mycoplasmas from ruminants based on 16s rrna sequences and definition of a new cluster within the hominis group. | almost complete (> 96%) 16s rrna sequences from nine ruminant mycoplasmas have been determined by solid-phase dna sequencing. polymorphisms were found in four of the 16s rrna sequences, which indicated the existence of two different rrna operons. seven polymorphisms were found in mycoplasma agalatiae, three were found in mycoplasma bovis, one was found in mycoplasma alkalescens, and one was found in mycoplasma bovirhinis. the sequence data were used for construction of phylogenetic trees. all bu ... | 1996 | 8863441 |
| mastitis outbreak due to mycoplasma californicum and mycoplasma canadense in a commercial dairy herd in the state of jalisco, méxico. | a commercial dairy herd with 282 cows in lactation suddenly began to have a problem with atypical clinical mastitis. the first 28 cases showed severe purulent mastitis with hard swollen mammary glands, but without systemic signs of illness some of the cows were lame. the cases were not responsive to antibiotics. the evidence suggested that milking machine malfunction and other management practices may have contributed to spread infection and to increase the number of clinical cases. culture of m ... | 1999 | 10932757 |
| pasteurization of discard mycoplasma mastitic milk used to feed calves: thermal effects on various mycoplasma. | discard milk from sick or antibiotic-treated cows is often used as an economical alternative to milk replacer at dairy farms. this practice poses a health risk to calves if the discard milk is from cows with mycoplasma mastitis. mycoplasma bovis, mycoplasma californicum, and mycoplasma canadense are among the agents known to cause contagious mastitis in cattle and occasionally pneumonia, otitis media, or arthritis in calves. this report describes a recent outbreak of calf polyarthritis and respi ... | 2000 | 11049070 |
| abattoir-based survey of contagious bovine pleuropneumonia in cattle in turkey. | blood samples collected from 945 cattle at four local abattoirs in turkey were examined for contagious bovine pleuropneumonia (cbpp) by the complement fixation test (cft) and competitive elisa (celisa). in addition, the carcases of the animals were examined macroscopically at the abattoirs and 62 lung samples which had lesions suggestive of cbpp were collected for bacteriological culture. to identify suspicious isolates the pcr was used in addition to the routine biochemical tests. by the cft, t ... | 2003 | 12638910 |
| experimental pathogenicity evaluation of mycoplasma canadense from bovine mastitis in vitro and in vivo laboratory models. | mycoplasma canadense, a clinical isolate from milk of a mastitic buffalo, was experimentally tested for its pathogenic potential in hamster tracheal ring and rabbit fallopian tube explant organ cultures (in vitro) and rat and rabbit mammary gland (in vivo) models. the activity percentage reduction in m. canadense infected hamster tracheal rings was 99.1% in comparison to 16.4% in control rings. mycoplasma canadense, also induced complete ciliostasis at 11-day post-infection in rabbit fallopian t ... | 2004 | 15282947 |
| identification of mycoplasma bovigenitalium and mycoplasma canadense from outbreaks of granulopapular vulvovaginitis in dairy cattle in israel. | a syndrome in which white foci and granulopustular lesions appeared on the vaginal mucous membranes of holstein cows in several dairy herds in israel is described. during clinical and diagnostic investigations, mycoplasma bovigenitalium was isolated from 11 of 20 clinical cases. vaginal swabs taken from the same cows yielded three isolates of mycoplasma canadense, which were all associated with the m bovigenitalium infection. two isolates of small, round, non-enveloped viral particles were appro ... | 2009 | 19749209 |
| detection of bacterial and viral organisms from the conjunctiva of cats with conjunctivitis and upper respiratory tract disease. | a variety of pathogens are involved in conjunctivitis in cats. in this study, the prevalence of feline herpesvirus (fhv), chlamydophila felis, mycoplasmas, and aerobic bacteria on the conjunctival surface of cats with conjunctivitis and upper respiratory tract disease was investigated by polymerase chain reaction (pcr), immunofluorescent assay (ifa), and aerobic bacterial culture of ocular swabs. forty-one cats were included of which 37 were found to be infected with an ocular organism. single a ... | 2010 | 20817584 |
| validation of a mycoplasma molecular diagnostic test and distribution of mycoplasma species in bovine milk among new york state dairy farms. | mycoplasma mastitis is a contagious and costly disease of dairy cattle that significantly affects animal health and milk productivity. mycoplasma bovis is the most prevalent and invasive agent of mycoplasma mastitis in dairy cattle, and early detection is critical. other mycoplasma have been isolated from milk; however, the role and prevalence of these species as mastitis pathogens are poorly understood. routine screening of milk for mycoplasma by bacteriological culture is an important componen ... | 2016 | 27016831 |
