Acinetobacter baumannii continues to be a major health problem especially in hospital settings. Herein, features that may play a role in persistence and disease potential were investigated in a col...

A group of yellow-pigmented isolates from ammonia-supplied biofilters showed an unusual denitrification reaction. All strains reduced nitrite but not nitrate without production of nitrogen (N-2). T...

Four highly polymorphic simple sequence repeat (SSR) loci were selected and used to differentiate 84 Japanese isolates of "Candidatus Liberibacter asiaticus." The Nei's measure of genetic diversity...

Certain pathogens evolve with their hosts in a stepwise arms race of virulence and resistance, mediated by one or a few genetic loci in their genomes. Other pathogens may retain the ability to colo...

Citrus variegated chlorosis (CVC) and coffee stern atrophy (CSA) are important diseases in Brazil associated with closely-related strains of Xylella fastidiosa, but little is know about host overla...

Xanthomonas fragariae, the causal organism of angular leaf spot on cultivated strawberry (Fragaria x ananassa), is an economically important pathogen of nursery stock in California. The ability to ...

This opinion addresses a request from the European Commission to evaluate whether heterogeneous populations of Xylella fastidiosa subsp. pauca have been found in Apulia (Italy) in addition to the s...

The quinolone resistance-determining regions (QRDRs) of topoisomerase II and IV genes from Stenotrophomonas maltophilia ATCC 13637 were sequenced and compared with the corresponding regions of 32 u...
