Phylogeny and DNA-DNA hybridization.
Resolving the phylogeny of the hominoid primates is a test case for molecular systematic methods because, by most genetic measures, humans, chimpanzees, and gorillas are very closely related. Recently, Sibley and Ahlquist (1984) applied DNADNA hybridization techniques to infer the hominoid phylogenetic tree with humans and chimpanzees closest. Templeton (1983, 1985) argues rather that the chimp...
متن کاملHeat resistance and mechanism of heat inactivation in thermophilic campylobacters.
The heat resistance of Campylobacter jejuni strains AR6 and L51 and the heat resistance of Campylobacter coli strains DR4 and L6 were measured over the temperature range from 50 to 60 degrees C by two methods. Isothermal measurements yielded D55 values in the range from 4.6 to 6.6 min and z values in the range from 5.5 to 6.3 degrees C. Dynamic measurements using differential scanning calorimet...
متن کاملDNA-DNA hybridization study of Bradyrhizobium strains.
DNA-DNA hybridizations were performed between Bradyrhizobium strains, isolated mainly from Faidherbia albida and Aeschynomene species, as well as Bradyrhizobium reference strains. Results indicated that the genus Bradyrhizobium consists of at least 11 genospecies, I to XI. The genospecies formed four subgeneric groups that were more closely related to each other (>40% DNA hybridization) than to...
متن کاملRecovery of Resistant Thermophilic Campylobacters on Farm and Market Vegetables
Campylobacter are zoonotic pathogens that frequently cause diarrhoea in humans often surpassing salmonellosis and shigellosis with C. jejuni and C. coli species mostly implicated (EFSA, 2013; WHO, 2015). Consumption of undercooked meat is the main source of human infections and the most significant risk factor. Nevertheless, environmental routes such as faecally contaminated water serving as co...
متن کاملImproved toluidine blue-DNA agar for detection of DNA hydrolysis by campylobacters.
Our improved toluidine blue-DNA agar was compared with methyl green DNase test agar for the detection of DNA hydrolysis by campylobacters. The toluidine blue-DNA agar gave clear-cut positive and negative reactions with campylobacter strains belonging to several species.
