early onset morganella morganii sepsis in a newborn infant with emergence of cephalosporin resistance caused by depression of ampc beta-lactamase production..a preterm infant with early onset morganella morganii sepsis was treated with cefotaxime and gentamicin after confirmation of antimicrobial susceptibility. the infant developed persistent ventriculitis caused by the emergence of a cefotaxime-resistant morganella variant with derepression of its ampc beta-lactamase. when choosing antibiotic therapy, the risk of development of resistance to cephalosporins should be considered in infections caused by m. morganii and other gram-negative organisms wi ...200616567997
morganella morganii pericarditis 3 years after allogenic bone marrow transplantation for mantle cell lymphoma.we report herein a case of morganella morganii-associated acute purulent pericarditis that developed 3 years after allogenic bone marrow transplantation. the patient was successfully treated with surgical drainage and cefotaxime for 6 weeks. splenectomy and immunosuppression for chronic gvh-d are likely to have favored the development of this rare infectious complication after bmt. m. morganii should be added to the list of bacteria causing purulent pericarditis, especially in immunocompromised ...200616569434
formation of histamine and biogenic amines in cold-smoked tuna: an investigation of psychrotolerant bacteria from samples implicated in cases of histamine fish poisoning.two outbreaks and a single case of histamine fish poisoning associated with cold-smoked tuna (cst) were reported in denmark during 2004. the bacteria most likely responsible for histamine formation in cst implicated in histamine fish poisoning was identified for the first time in this study. product characteristics and profiles of biogenic amines in the implicated products were also recorded. in the single poisoning case, psychrotolerant morganella morganii-like bacteria most likely was responsi ...200616629036
improved production of enzymes, which are expressed under the pho regulon promoter, in the rmf gene (encoding ribosome modulation factor) disruptant of escherichia coli.using a dna macroarray, we investigated the effects of rmf gene (encoding ribosome modulation factor) disruption on gene expression profiles in escherichia coli. this strain showed a phosphate-starvation-like response in gene expression even under phosphate sufficient conditions; significant upregulation of the pho regulon genes was observed. further, the production of alkaline phosphatase, a product of the pho regulon gene, phoa, increased in the rmf disruptant under a pi sufficient condition. ...200616636463

histidine decarboxylases and their role in accumulation of histamine in tuna and dried saury.histamine-producing bacteria (hpb) such as photobacterium phosphoreum and raoultella planticola possess histidine decarboxylase (hdc), which converts histidine into histamine. histamine fish poisoning (hfp) is attributable to the ingestion of fish containing high levels of histamine produced by hpb. because freezing greatly decreases the histamine-producing ability of hpb, especially of p. phosphoreum, it has been speculated that hfp is caused by hdc itself from hpb cells autolyzing during froze ...200717220267

microfluidic chip analysis of outer membrane proteins responsible for serological cross-reaction between three gram-negative bacteria: proteus morganii o34, escherichia coli o111 and salmonella adelaide o35.bacterial strains have complex and individual antigenic structure, which provides basis for their serological identification. however, serological cross-reaction may occur when antibodies against a certain strain recognize other strains too. the molecular basis of this phenomenon is the expression of similar or identical antigenic epitopes on the surface of different bacterial cells. such cross-reactions might harden the serological diagnosis of pathogenic bacteria. but it can be also advantageo ...200717362972

[evaluation of vitek 2 performance for identifying extended spectrum beta-lactamases in enterobacteriaceae "other than escherichia coli, proteus mirabilis and klebsiella spp"].production of beta-lactamases is the main resistance mechanism of gram-negative bacteria against beta-lactam antibiotics. extended spectrum beta-lactamases (esbls) have the ability to hydrolyze a broader spectrum of beta-lactam drugs. hence rapid, accurate detection of this resistance mechanism is extremely important to guide proper patient antimicrobial therapy. these enzymes are most commonly produced by klebsiella spp. and escherichia coli, but may also occur widely in other gram-negative bac ...200617380089
