Antibacterial Activity of Propolis Extracts from the Central Region of Romania against Neisseria gonorrhoeae
2021
(1) Background: Sexually transmitted infections (STIs) are among the most common infections worldwide, many of these being caused by Neisseria gonorrhoeae (NG). Increased antimicrobial NG resistance has been reported in recent decades, highlighting the need for new sources of natural compounds with valuable antimicrobial activity. This study aims to determine the effect of propolis extracts on NG strains, including antibiotic-resistant strains. (2) Methods: First void urine samples from presumed positive STI subjects were harvested. DNA was extracted, purified, and amplified via PCR for the simultaneous detection of 6 STIs. The presence of the dcmH, gyrA, and parC genes was checked in the D…
Molecular diagnostic of Ureaplasma urealyticum presence and tetracycline resistance in urine samples
2021
Abstract Sexually transmitted infections (STIs) are among the most common infections in Romania. Infection with Ureaplasma urelyticum is one of the major causes of STIs and can cause serious complications. Although tetracycline is the drug commonly used to treat infections caused by U. urealyticum, several studies indicate the emergence and rapid development of strains resistant to these antibiotics in the United States or Europe. Tetracycline resistance in bacteria is encoded by a number of different genetic determinants but in mycoplasmas the only tetracycline resistance determinant that has been reported is the tetM gene. Tetracycline resistance among Ureaplasma spp. is associated with t…
The antimicrobial activity of honey and propolis extracts from the central region of Romania
2021
Abstract Honey and propolis from Apis mellifera (bees) are products that have been used due to their multiple biological properties. The antimicrobial activity of 10 honey samples of known origin and 4 propolis extracts gathered from the same beekeepers located in Transylvania, Romania, were used against certain microorganisms: Escherichia coli, Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa and Candida albicans. The study also investigated the positive interaction of propolis aqueous extracts when used with poly-floral honey against the same microorganisms. The most sensitive to the activity of honey samples was the S. aureus strain (the largest inhibition area 18 mm) for p…
