Substrate utilization by Campylobacter jejuni and Campylobacter coli.
An attempt was made to elucidate in Campylobacter spp. some of the physiologic characteristics that are reflected in the kinetics of CO2 formation from four 14C-labeled substrates. Campylobacter jejuni and C. coli were grown in a biphasic medium, and highly motile spiral cells were harvested at 12 h. Of the media evaluated for use in the metabolic tests, minimal essential medium without glutami...
متن کاملUtilization of Exogenous Inorganic Carbon Species in Photosynthesis by Chlorella pyrenoidosa.
The nature of the inorganic carbon utilized during photosynthesis by Chlorella pyrenoidosa was investigated using three experimental techniques (open gas analysis system with "artificial leaf" or "aqueous" chambers and O(2) electrode system) to measure carbon assimilation. Photosynthesis was studied as a function of pH and CO(2) concentration. The CO(2) concentration was inadequate to meet the ...
متن کاملPrevalence of Campylobacter jejuni and Campylobacter coli in captive wildlife species of India
Campylobacteriosis is an important zoonotic disease and the prevalence of Campylobacter is largely unknown in the wildlife of India. A total of 370 samples, comprising of 314 fresh faecal samples from apparently healthy captive wild animals and birds, 30 stool swabs from animal care takers and 26 samples of the animals’ food and water were collected from G. B. Pant High Altitude Zoo, Nainital, ...
متن کاملHydrolysis of indoxyl acetate by Campylobacter species.
One hundred and twelve Campylobacter strains comprising 15 species and subspecies were examined for their ability to hydrolyze indoxyl acetate. All strains of C. coli, C. cryaerophila, C. fennelliae, and C. jejuni hydrolyzed the compound, whereas three strains of C. cinaedi were negative and a fourth was weakly positive. Representatives of all other species were negative. Organisms that hydroly...
متن کاملHeme utilization in Campylobacter jejuni.
A putative iron- and Fur-regulated hemin uptake gene cluster, composed of the transport genes chuABCD and a putative heme oxygenase gene (Cj1613c), has been identified in Campylobacter jejuni NCTC 11168. Mutation of chuA or Cj1613c leads to an inability to grow in the presence of hemin or hemoglobin as a sole source of iron. Mutation of chuB, -C, or -D only partially attenuates growth where hem...
