Nowadays, fungal infections increase, and the demand of novel antifungal agents is constantly rising. In present study, silver, titanium dioxide, cobalt (II) hydroxide (II,III) oxide nanomaterials have been synthesized from Spirulina platensis extract. The synthesis mechanism has studied using GCMS FTIR thus confirming involvement secondary metabolites, mainly amines. obtained products analysed XRD, SEM, TGA zeta potential techniques. findings revealed average crystallite size 15.22 nm with...

The cultivation of cyanobacteria by exploiting available in situ resources represents a possible way to supply food and oxygen astronauts during long-term crewed missions on Mars. Here, we evaluated the possibility cultivating extremophile cyanobacterium Chroococcidiopsis thermalis CCALA 050 under operating conditions that should occur within dome hosting recently patented process produce nutrients medium adopted cultivate this cyanobacterium, named Martian medium, was obtained using mixture...

ABSTRACT Resident mucosal pathogens may induce immune tolerance breach, specific autoimmune response, and the development of rheumatoid arthritis (RA) in susceptible individuals. Despite a number studies linking infections by Mollicutes bacteria to disorders’ onset progression, role Mycoplasma hominis , common urogenital mucosa colonizing bacterium, inducing humoral response RA has been seldom addressed. This study reports M. seroprevalence patients compared healthy controls (HC) testing two...

The symbiosis between the parasitic protist Trichomonas vaginalis and opportunistic bacterium Mycoplasma hominis is only one currently described involving two obligate human mucosal symbionts with pathogenic capabilities that can cause independent diseases in same anatomical site: lower urogenital tract. Although several aspects of this intriguing microbial partnership have been investigated, many questions on influence parasite pathobiology still remain unanswered. Here, we examined vitro...

Trichomonas vaginalis can host the endosymbiont Mycoplasma hominis, an opportunistic pathogenic bacterium capable of modulating T. pathobiology. Recently, a new noncultivable mycoplasma, "

Mycoplasma hominis is considered an opportunistic pathogen able to colonize the lower urogenital tract; in females infection associated with severe pregnancy and postpartum complications, including abortion, endometritis, preterm delivery, low birth weight. Molecular mechanisms of pathogenicity virulence effectors remain poorly characterized. A number studies last decade have demonstrated that M. can establish endosymbiotic relationship Trichomonas vaginalis, a parasitic protozoon, also...

(1) Background: It has been previously shown that sourdough bread, compared to commercial yeast elicits a lower postprandial glycemic and insulinemic response in patients with impaired glucose tolerance (IGT). Aims: Our aim was evaluate the following aspects persons type 2 diabetes (T2DM): variations induced by three different doughs: X = bread prepared functional alkaline biocrystal water, Y sourdough-leavened W bakery bread; (2) utility of flash monitoring (FGM) measure GL. Methods: Twelve...

Trichomoniasis, the most common non-viral sexually transmitted infection worldwide, is caused by protozoon Trichomonas vaginalis. The 5- nitroimidazole drugs, of which metronidazole prescribed, are only effective drugs to treat trichomoniasis. Resistance against increasingly reported among T. vaginalis isolates. can establish an endosymbiosis with two Mycoplasma species, hominis and Candidatus girerdii, whose presence has been demonstrated influence several aspects protozoan pathobiology....

Vaginal infections affect millions of women annually worldwide. Therapeutic options are limited, moreover drug-resistance increases the need to find novel antimicrobials for health promotion. Recently phytochemicals were re-discovered medical treatment. Myrtle (Myrtus communis L.) plant extracts showed in vitro antioxidant, antiseptic and anti-inflammatory properties thanks their bioactive compounds. The aim present study was create nanodevices deliver three natural from leaves, seeds fruit...

Mycoplasma hominis, an opportunistic pathogen of the human lower urogenital tract, can survive and replicate within protozoan Trichomonas vaginalis, establishing endosymbiotic relationship. The intracellular location may provide a means for bacteria to evade immune system protection from antimicrobial activities. Our aim was investigate influence association M. hominis with trichomonad cells on bacterial antibiotic susceptibility. We evaluated resistance patterns in group isolated T....
