We designed and synthesized five new 5-nitrothiazole-NSAID chimeras as analogues of nitazoxanide, using a DCC-activated amidation. Compounds 1-5 were tested in vitro against a panel of five protozoa: 2 amitochondriates (Giardia intestinalis, Trichomonas vaginalis) and 3 kinetoplastids (Leishmania mexicana, Leishmania amazonensis and Trypanosoma cruzi). All chimeras showed broad spectrum and potent antiprotozoal activities, with IC50 values ranging from the low micromolar to nanomolar order. Compounds 1-5 were even more active than metronidazole and nitazoxanide, two marketed first-line drugs against giardiasis...

BACKGROUND: Enterococcus faecalis is a microorganism commonly detected in asymptomatic, persistent endodontic infections. Triple antibiotic paste has stood the test of time as a proven antibiotic combination against E. Faecalis. However, problems with this include staining of teeth and standardization of the preparation. Thus, the search for better alternatives and better preparation techniques is still on. AIM: To observe the potential of combinations [(Amoxicillin+ Metronidazole, Amoxicillin Clavulanic Acid + Metronidazole; Amoxicillin and Cloxacillin + Metronidazole)] over Triple Antibiotic Paste...

A variant of dielectric-barrier discharge named surface desorption dielectric-barrier discharge ionization (SDDBDI) mass spectrometry was developed for high-efficiency ion transmission and high spatial resolution imaging. In SDDBDI, a tungsten nanotip and the inlet of the mass spectrometer are used as electrodes, and a piece of cover slip is used as a sample plate as well as an insulating dielectric barrier, which simplifies the configuration of instrument and thus the operation. Different from volume dielectric-barrier discharge (VDBD), the microdischarges are generated on the surface at SDDBDI, and therefore the plasma density is extremely high...

Trichomonas vaginalis, the most common non-viral sexually transmitted parasite, causes ∼283 million trichomoniasis infections annually and is associated with pregnancy complications and increased risk of HIV-1 acquisition. The antimicrobial drug metronidazole is used for treatment, but in a fraction of clinical cases, the parasites can become resistant to this drug. We undertook sequencing of multiple clinical isolates and lab derived lines to identify genetic markers and mechanisms of metronidazole resistance...

Hyoung-Chul Park, Min Jeong Kim, Bong Hwa Lee
BACKGROUND: Although it is accepted that complicated appendicitis requires antibiotic therapy to prevent post-operative surgical infections, consensus protocols on the duration and regimens of treatment are not well established. This study aimed to compare the outcome of post-operative infectious complications in patients receiving old non-standardized and new standard antibiotic protocols, involving either 5 or 10 days of treatment, respectively. METHODS: We enrolled 1,343 patients who underwent laparoscopic surgery for complicated appendicitis between January 2009 and December 2014...

Genital mycoplasmas, which can be vertically transmitted, have been implicated in preterm birth, neonatal infections, and chronic lung disease of prematurity. Our prior work uncovered 16S rRNA genes belonging to a novel, as-yet-uncultivated mycoplasma (lineage 'Mnola') in the oral cavity of a premature neonate. Here, we characterize the organism's associated community, growth status, metabolic potential, and population diversity. Sequencing of genomic DNA from the infant's saliva yielded 1.44 Gbp of high-quality, non-human read data, from which we recovered three essentially complete (including 'Mnola') and three partial draft genomes (including Trichomonas vaginalis)...

Chronic alcohol consumption perturbs the normal intestinal microbial communities (dysbiosis). To investigate the relationship between alcohol-mediated dysbiosis and pulmonary host defense we developed a fecal adoptive transfer model, which allows us to investigate the impact of alcohol-induced gut dysbiosis on host immune response to an infectious challenge at a distal organ, independent of prevailing alcohol use. Male C57BL/6 mice were treated with a cocktail of antibiotics (ampicillin, gentamicin, neomycin, vancomycin, and metronidazole) via daily gavage for two weeks...
