Advances in next-generation sequencing (NGS) technologies since 2005 have revolutionized biological science. One particular application of NGS is to elucidate microbiomes built environments. We are currently conducting a series studies on the elucidation and control mass infection mechanisms based dynamic measurement environment microbiomes. The objective this study clarify dispersion character...

female sex worker; thus, the bacteria could have derived from her pharynx. N. gonorrhoeae strain H041 was previously isolated from the pharynx of a female sex worker (1). To prevent the emergence and spread of ceftriaxone-resistant N. gonorrhoeae, pharyngeal gonorrhea must be treated. It is uncertain whether a 1-g dose of ceftriaxone would be effective against pharyngeal gonorrhea caused by str...

Members of the genus Neisseria include pathogens causing important human diseases such as meningitis, septicaemia, gonorrhoea and pelvic inflammatory disease syndrome. Neisseriae are found on the exposed epithelia of the upper respiratory tract and the urogenital tract. Colonisation of these exposed epithelia is dependent on a repertoire of diverse bacterial molecules, extending not only from t...

Two Neisseria gonorrhoeae isolates from Seattle and two isolates from Uruguay were resistant to erythromycin (MIC, 4 to 16 microg/ml) and had reduced susceptibility to azithromycin (MIC, 1 to 4 microg/ml) due to the presence of the self-mobile rRNA methylase gene(s) ermF or ermB and ermF. The two Seattle isolates and one isolate from Uruguay were multiresistant, carrying either the 25.2-MDa tet...

A dual-purpose study was carried out in an attempt to develop a rapid, sensitive method to identify Neisseria species by gas chromatography and to learn more about the metabolism of these organisms. Sixty-nine isolates of Neisseria were grown in a chemically defined fluid medium; the spent medium was extracted sequentially at pH 2 with diethyl ether and at pH 10 with chloroform. The pH 10 extra...

The sexually transmitted bacterium Neisseria gonorrhoeae has developed resistance to all antibiotic classes that have been used for treatment and strains resistant to multiple antibiotic classes have evolved. In many countries, there is only one antibiotic remaining for empirical N. gonorrhoeae treatment, and antibiotic management to counteract resistance spread is urgently needed. Understandin...

The Phadebact Monoclonal GC OMNI Test (Pharmacia Diagnostics, Piscataway, N.J.) is used for the definitive identification of Neisseria gonorrhoeae. In this test, boiled organisms are examined by using a 1-min coagglutination technique. A total of 776 Neisseria strains, confirmed to the species level by patterns of acid production from carbohydrates incorporated in cysteine-tryptose agar or morp...

The genus Neisseria contains at least eight commensal and two pathogenic species. According to the Neisseria phylogenetic tree, commensals are basal to the pathogens. N. elongata, which is at the opposite end of the tree from N. gonorrhoeae, has been observed to be fimbriated, and these fimbriae are correlated with genetic competence in this organism. We tested the hypothesis that the fimbriae ...
