Objective(s): Klebsiella infections are caused mainly by K. pneumoniae and K. oxytoca. In the last two decades, a new type of invasive Klebsiella pneumoniae which contains mucoviscosity-associated gene (magA) has emerged. The aim of this study was to investigate the prevalence of magA gene and to detect antimicrobial susceptibility patterns of Klebsiella   spp. isolated from clinical samples....

BACKGROUND Primary pyogenic liver abscess (PLA) caused by Klebsiella pneumoniae is an emerging infectious disease. Capsular serotype K1 and the magA gene have been reported to be associated with this disease. METHODS The prevalence of magA was determined by polymerase chain reaction (PCR). The sequences of the magA flanking region were completed by inverse PCR and direct sequencing. Serotypin...

In this issue of the Journal, Yeh et al [1] revisit the importance of magA in Kleb-siella pneumoniae causing pyogenic liver abscess, as well as its exact role in serotype K1 capsule formation. The mucoviscosity-associated gene A (magA) of K. pneumo-niae was originally discovered in 2002 by me and my colleagues [2, 3] in tissue-invasive K. pneumoniae strains causing primary liver abscess complic...

PURPOSE The ability to longitudinally monitor cell grafts and assess their condition is critical for the clinical translation of stem cell therapy in regenerative medicine. Developing an inducible genetic magnetic resonance imaging (MRI) reporter will enable non-invasive and longitudinal monitoring of stem cell grafts in vivo. METHODS MagA, a bacterial gene involved in the formation of iron o...

objective(s): klebsiella infections are caused mainly by k. pneumoniae and k. oxytoca. in the last two decades, a new type of invasive klebsiella pneumoniae which contains mucoviscosity-associated gene (maga) has emerged. the aim of this study was to investigate the prevalence of maga gene and to detect antimicrobial susceptibility patterns of klebsiella   spp. isolated from clinical samples.  ...

Magnetospirillum sp. AMB-1 is a freshwater magnetic bacterium which synthesizes intracellular particles of magnetite (Fe3O4). A genomic DNA fragment required for synthesis of magnetic particles was previously isolated from a nonmagnetic transposon Tn5 mutant. We have determined the complete nucleotide sequence of this fragment. The 2975-base pair region contains two putative open reading frames...

background and objectives: klebsiella pneumoniae ( k. pneumoniae ) is an opportunistic microorganism. this study aimed to investigate the presence of mag a gene and antimicrobial susceptibility in k. pneumoniae . materials and methods: 195 clinical specimens were collected from hospitals of shahrekord, iran. bacterial culture, biochemical diagnostic standard test, determination of antibiotic se...

Taiwan has witnessed an emerging syndrome of liver abscess caused by Klebsiella pneumoniae carrying the magA gene required for exopolysaccharide web biosynthesis. We report a patient transferred from Alaska to Washington State with a magA(+) K. pneumoniae liver abscess and describe a simple approach for recognition of these hypervirulent strains.

Magnetotactic bacteria have the ability to orient along geomagnetic field lines based on the formation of magnetosomes, which are intracellular nanometer-sized, membrane-enclosed magnetic iron minerals. The formation of these unique bacterial organelles involves several processes, such as cytoplasmic membrane invagination and magnetosome vesicle formation, the accumulation of iron in the vesicl...
