A newly isolated smooth colony morphology phage-resistant strain 8416 isolated from a 45-year-old cattle farm cleaner with clinical features of brucellosis in China was reported. The most unusual phenotype was its resistance to two Brucella phages Tbilisi and Weybridge, but sensitive to Berkeley 2, a pattern similar to that of Brucella melitensis biovar 1. VITEK 2 biochemical identification sys...
Twenty-one small Gram-negative motile coccobacilli were isolated from 15 systemically diseased African bullfrogs (Pyxicephalus edulis), and were initially identified as Ochrobactrum anthropi by standard microbiological identification systems. Phylogenetic reconstructions using combined molecular analyses and comparative whole genome analysis of the most diverse of the bullfrog strains verified ...
The cellular fatty acid composition of Brucella canis and Brucella suis was determined by gas-liquid chromatography. The presence of relatively large amounts of a 19-carbon cyclopropane fatty acid in B. suis was a major distinguishing feature between these organisms. The gas-liquid chromatography test for cellular fatty acids provides an additional criterion for the distinction of antigenically...
Background and purpose: Synthetic fertilizers damage the environment. Biofertilizers that consist of microorganisms emerge as an environmentally friendly alternative. improve plant growth by mobilizing soil nutrients, triggering hormone synthesis, or competing with pathogenic bacteria. However, biofertilizers often fail due to insufficient colonization roots.Materials methods: To explore dynami...
The DNAs of two viable strains of simian virus 40, 776 and 777, have been compared by using restriction endonucleases. Differences between the two strains were detected at five separate points on the simian virus 40 genome. One of these differences, in the region of DNA coding for the major viral coat protein, was confirmed by tryptic peptide analysis of coat proteins from the two strains. Some...
Background & Objective: Persister cells are defined as a subpopulation of bacteria that are capable of reducing their metabolism and switching to dormancy in stress conditions. Persister cells formation has been attributed to numerous mechanisms, including stringent response and Toxin-Antitoxin (TA) systems. This study aimed to investigate the hypothetical role of TA systems in...
To clarify the taxonomic status of two recently described Borrelia genomic groups, groups VS116 and M19, three group VS116 strains and eight group M19 strains isolated from Ixodes ricinus ticks in Switzerland, The Netherlands, and the United Kingdom were characterized. PCR-restriction fragment length polymorphism (RFLP) analysis of the 5S-23S intergenic spacer amplicon, rRNA gene restriction an...
Brucellosis is named after Dr. David Bruce who first isolated the bacterium that caused Malta fever from four fatal cases amongst the British forces on the island. The genus Brucella was subsequently proposed after similar bacteria were isolated from cattle and swine and the zoonotic connection recognized. The close similarities between these isolates were acknowledged but nomen species were su...
