Shigella strains are in reality clones of Escherichia coli and are believed to have emerged relatively recently (G. M. Pupo, R. Lan, and P. R. Reeves, Proc. Natl. Acad. Sci. USA 97:10567-10572, 2000). There are 33 O-antigen forms in these Shigella clones, of which 12 are identical to O antigens of other E. coli strains. We sequenced O-antigen gene clusters from Shigella boydii serotypes 4, 5, 6...

Fusarium has recently emerged as an opportunistic pathogen of humans, but the histological differentiation of Fusarium from Aspergillus and Scedosporium is particularly difficult because these fungi may induce similar clinical features and exhibit filamentous development in host tissues. Thus, there is a need to establish rapid and reliable methods that are applicable to pathological diagnoses....

BACKGROUND Invasive fungal infection (IFI) is a leading cause of infection-related mortality among kidney allograft recipients.  OBJECTIVE To estimate the incidence and etiology of systemic fungal infection in renal allograft recipients in Sydney transplant facility. METHODS 471 kidney recipients, transplanted between 2000 and 2010 at the Westmead Hospital renal transplantation center, Sydn...

Ribosomal RNA (rRNA) is present in all prokaryotic and eukaryotic cells. Although sequences are conserved, variations in nucleic acid composition are known to be species specific. Formalin or Bouin's fixed, paraffin-embedded tissue specimens from 17 cases of culture proven Aspergillus sp infections were studied by a rapid (< 30 minutes) in situ hybridization procedure using a biotinylated oligo...

Pseudallescheria/Scedosporium species are filamentous fungi widely distributed in nature. Some are considered emerging pathogen due to its clinical importance, especially in immunocompromised patients. During the last few years, many virulence factors have been described, some of them being molecules localized on the fungal cell wall, such as glycoproteins, polysaccharides and glycolipids. In t...

Bacillary dysentery and acute gastroenteritis caused by infection of Shigella species are major public health burden in India and its neighboring countries. Emergence of antimicrobial resistance threatens to render current treatments ineffective. The current study was attempted to investigate the effect of biofield treatment on Shigella boydii (S. boydii) with respect of antimicrobial susceptib...

Two additional new compounds, pseudellone D (1) and (5S,6S)-dihydroxylasiodiplodin (3), along with the two known compounds lasiodipline F (2), (5S)-hydroxylasiodiplodin (4) were isolated from the marine-derived fungus Pseudallescheria ellipsoidea F42-3 associated with the soft coral Lobophytum crassum. Their structures, including absolute configurations, were elucidated on the basis of the corr...

Shigella is an important human pathogen. It is generally agreed that Shigella and Escherichia coli constitute a single species; the only exception is Shigella boydii type 13, which is more distantly related to E. coli and other Shigella forms and seems to represent another species. This gives S. boydii type 13 an important status in evolution. O antigen is the polysaccharide part of the lipopol...
