“…Approximately 800 bp of sequence was obtained per amplicon; these were compared with those deposited in the GenBank database, using the online BLAST program (http://www.ncbi.nlm.nih.gov/BLAST/) and with those in the Ribosomal Database Project (http://rdp.cme.msu.edu/index.jsp). Sequences sharing a percentage of identity of 97% or higher to those in databases were considered to belong to the same species (Stackebrandt et al 2002).…”

Bacteria may adhere to and develop biofilm structures onto dairy surfaces trying to protect themselves from adverse conditions such as pasteurization and CIP processes. Thus, biofilms are considered common sources of food contamination with undesirable bacteria. The purpose of this study was to evaluate the diversity of the microbiota attached to stainless steel surfaces in pre-and post-pasteurization pipe lines of a milk-processing plant. Seventy Gram-positive isolates were identified as Enterococcus faecalis (33), Bacillus cereus (26), Staphylococcus hominis (8), Staphylococcus saprophyticus (2), and Staphylococcus epidermidis-Staphylococcus aureus (1) species. Fifty-five Gram-negative isolates were identified to the species Escherichia coli (18), Klebsiella pneumoniae (13), Acinetobacter calcoaceticus (6), Serratia marcescens (6), Enterobacter spp. (5), Pseudomonas aeruginosa (4), Escherichia vulneris (2), and Proteus mirabilis (1). Fifty-five different strains were detected by the RAPD technique. These were subjected to an in vitro assay to evaluate their biofilm-forming capability. E. faecalis (7), A. calcoaceticus (4), K. pneumoniae (3), S. hominis (3), and P. aeruginosa (2) were the species in which more biofilm producer strains were encountered. The adhered microbiota was also assessed by the PCR-DGGE culture-independent technique. This analysis revealed a greater bacterial diversity than that revealed by culturing methods. In this way, in addition to the bacteria detected by culturing, DNA bands belonging to the genera Chrysobacterium and Streptomyces were also identified. This study emphasizes that knowledge of attached Dairy Sci. & Technol. (2016) 96:27-38 DOI 10.1007

“…According to the recommendations of the "Ad Hoc Committee for the re-evaluation of the species definition in bacteriology" (Stackebrand et al 2002), the name of this as yet uncultured organism should be "Candidatus Treponema paraluisleporis", pending further characterization (Euzéby 1997).…”

Widespread treponemal infections of hare populations (Lepus europaeus) in the Netherlands

Further to the first description of treponemal infection in hares (Lepus europaeus) in one province of the Netherlands (Flevoland), this report provides further evidence for the widespread occurrence of hare syphilis in this country. Hunter-bagged hares which had the typical lesions of the disease were serologically examined using the Treponema pallidum hemagglutination assay and the fluorescent treponemal antibody absorption test, and tissue samples were stained with the Bosma-Steiner modified silver stain. Nine out of 12 suspected hares from five different provinces from the Netherlands showed serological and histological evidence of syphilis. Hare populations from at least half of the provinces of the Netherlands are infected with this agent.

“…The reclassification of Enterobacter sakazakii to Cronobacter was based on a polyphasic approach that included DNA-DNA hybridisation, amplified fragment length polymorphisms (AFLP), automated ribotyping, full length 16S rRNA gene sequencing and phenotypic analysis 22,34 . A total of 210 strains, previously described as Enterobacter sakazakii were divided into 16 biogroups based on indole production, methyl red test, Voges-Proskauer, ornithine decarboxylase, motility, malonate utilisation and acid production from inositol, dulcitol and methylglucoside.…”

“…There is a high level of similarity between C. sakazakii and C. malonaticus and sequence analysis based on 16S rRNA is not sufficient to distinguish between these two species 22,31,33 . Biochemical differentiation between the two species can be accomplished by testing for the utilisation of malonate, although a small number of C. sakazakii strains do utilize malonate 34 . Controversial results regarding these two species have been found when the phenotypic data of 150 isolates was compared to ribotyping results 36 .…”

Cronobacter sakazakii (Enterobacter sakazakii): An Emerging Foodborne Pathogen

Cronobacter sakazakii (Enterobacter sakazakii) is an emerging pathogen that causes necrotizing enterocolitis, sepsis, and meningitis. This bacterium is opportunistic pathogen and is linked with life-threatening infections in neonates and elderly persons. It is considered as ubiquitous organism and can be found in a broad range of foods & food ingredients and in water, in a variety of areas, including hospitals and houses though outbreaks most commonly associated with the ingestion of contaminated powdered infant formula (PIF). International Commission on Microbiological Specifications for Foods has ranked C. sakazakii a “severe hazard for restricted populations.” It poses high tolerance to environmental stresses such as osmotic stress, elevated temperature etc. and decontamination processes and has broad antibiotic resistance and resistance to bile salts and disinfectants. Cronobacter sakazakii may survive in macrophage cells and efficiently attach to and invade epithelial cell lines, produce exopolysaccharide, form biofilm and has active efflux pumps. Controlling the organism in the production environment, thereby reducing dissemination, necessitates the provision of suitable diagnostic tools. Appropriate measures by parents, food and infant formula manufacturers, and health care providers, as well as understanding of the pathogenesis, are important in the prevention of C. sakazakii-related infections.

Report of the ad hoc committee for the re-evaluation of the species definition in bacteriology.

Abstract: An ad hoc committee for the re-evaluation of the species definition in bacteriology met in Gent, Belgium, in February 2002. The committee made various recommendations regarding the species definition in the light of developments in methodologies available to systematists.
