OBJECTIVES To screen novel small molecule compounds for inhibition of Mycoplasma bovis growth and to characterize their activity in terms of dose-dependency and ability to function in milk. METHODS Using a tetrazolium salt cytotoxicity assay, 480 natural compounds were screened to determine which of the small molecules have the potential to become therapeutic options for M. bovis prevention a...

Many extensive studies have been made on the glucose polymers, known as dextrans, whichare produced from sucrose by the transglucosidase activity of species in the genus Leucomostoc. Less work has been described, however, on similar polysaccharides produced from sucrose by streptococcal species. Niven, Smiley & Sherman (1941) reported that various strains of Streptococcus bovis, of unrecorded o...

Apnea, cyanosis, lethargy and prolongation in capillary filling time developed on the postnatal 37(th) day in a preterm baby who was born at the 30(th) gestational week with a birth weight of 1 300 g. Acute phase reactants and immature/total neutrophil count ratio were found to be high. The patient who was diagnosed with sepsis was successfully treated with meropenem which was started empirical...

in most countries, tuberculosis caused by mycobacterium bovis is mainly a disease of cattle but can infect buffalos too. the disease can be controlled successfully by mean of a test-and-slaughter program. in iran test-and-slaughter program has started since 1971 and prevalence of bovine tuberculosis reduces from 5% to less than 0.12% in recent years. in western azarbaijan, north west of iran, t...

Maintenance energy expenditures were mesured for five rumen bacteria, Selenomonas ruminantium, Butyrivibrio fibrisolvens, Bacteroides ruminicola, Megasphaera elsdenii, and Streptococcus bovis, by using a complex medium with glucose as the carbon source. Large differences (as high as 8.5-fold) in maintenance energy expenditures were seen among these bacteria. The suggestion is made that maintena...

Fermentation pathways have been elucidated for predominant ruminal bacteria, but information is limited concerning the specific transport mechanisms used by these microorganisms for C, energy, and N sources. In addition, it is possible that changes in ruminal environmental conditions could affect transport activity. Five carrier-mediated soluble nutrient transport mechanisms have been identifie...

a two-year laboratory study on the biology (including self-fertilization) of bulinus truncatus, the intermediate host of schistosoma haematobium, s. bovis and paramphistomum microbotrium in iran, has revealed information on the longevity, reproduction, hatchability rate, hatching time during various months of the year, and growth and mortality rates of this snail. it was found that the reproduc...

M. bovis is a zoonosis and is the aetiological agent o f bovine TB. The incidence of bovine TB in the UK is increasing, demonstrating that the current test and slaughter policy is failing. M. bovis-BCG, the vaccine used against human TB, is not used in cattle as it interferes with the tuberculin skin test and only confers partial protection. The control o f bovine TB will require the design o f...

BACKGROUND Schistosomes are dioecious parasitic flatworms, which live in the vasculature of their mammalian definitive hosts. They are the causative agent of schistosomiasis, a disease of considerable medical and veterinary importance in tropical and subtropical regions. Schistosomes undergo a sexual reproductive stage within their mammalian host enabling interactions between different species,...

BACKGROUND:Mastitis is the most economically importantdisease in dairy industry worldwide. Bulk tank milk (BTM)analysis has been suggested for monitoring the udder healthstatus at herd level. OBJECTIVES: A cross-sectional study wasconducted to evaluate udder health status in 15 Holstein dairyfarms located in Qom province. METHODS: Bulk tank somaticcell count (BTMSCC) was analyzed using opto-flu...
