Study of zoonotic bacteria in conventional laboratory mice breeding colonies
To investigate the status of conventional laboratory mice colonies for zoonotic bacteria, three mice colonies, NIH, NMRI and Balb/c strains of Razi institute were studied for five zoonotic bacteria including Pasteurella pneumotropica, Salmonella typhimurium, Salmonella enteritidis, Streptobacillus moniliformis, Streptococcus Pneumonia. Study populations were 74 mice of premature, mature and pos...
متن کاملZero prevalence of extended spectrum beta-lactamase-producing bacteria in 300 breeding Collared Flycatchers in Sweden
Wild birds are important indicators and potential spreaders of antibiotic resistance. The order Passerines is scarcely studied apart from Corvus sp. but extended spectrum beta-lactamases (ESBLs) has been found in Blackbirds. We tested 300 fecal samples from a well-studied population of Collared Flycatchers (Ficedula albicollis) at the Island of Gotland in Sweden and found no ESBL-producing bact...
متن کاملProduction of Biomass of Photosynthetic Bacteria on Base of Stock-breeding and Poultry Wastes
On base of stock-breeding and poultry wastes the cheap nutrient media for cultivation and production of biomass of phototrophic bacteria have been developed. Cultivation of purple nonsulfur bacteria Rhodobacter sphaeroides together with Bacillus megaterium in mixed culture has been succeeded in high biomass yield. The obtained biomass was distinguished with rich contents of biologically active ...
متن کاملIsolation of mosquito-toxic bacteria from mosquito-breeding sites in Kenya.
A large number of source materials were collected for isolating entomopathogenic bacteria from larval mosquito habitats in Kirinyaga District, Kenya. Mosquito-toxic bacteria were included among the numerous types of microorganisms isolated from the habitats. The pathogenic isolates shared common structural characteristics; they were gram-positive, spore-forming bacilli that produced parasporal ...
متن کاملBreeding and Genetics: Dairy Cattle Breeding I
Humans obtain a number of products from animals. These include food, clothing, medical materials, companionship and research knowledge to name a few. A valued ethic contends that it is inappropriate for one to treat another as a means to an end. In short, it is wrong to treat another as simply a product. Historically, non-human beings have not been included as “others” and thus their treatment ...
