Two novel series of tris-cationic, tripled-headed, double-tailed amphiphiles were synthesized and the effects of tail length and head group composition on the critical aggregation concentration (CAC), thermodynamic parameters, and minimum inhibitory concentration (MIC) against six bacterial strains were

Bacterial epiphytes isolated from marine eukaryotes were screened for the production of quorum sensing inhibitory compounds (QSIs). Marine isolate KS8, identified as a Pseudoalteromonas sp., was found to display strong quorum sensing inhibitory (QSI) activity against acyl homoserine lactone (AHL)-based reporter strains Chromobacterium violaceum ATCC 12472 and CV026. KS8 supernatant significantl...

Papaya ( Carica papaya ) is found throughout Indonesia. flowers contain saponin, tannin, alkaloid, and flavonoid compounds which functions as antibacterial. Escherichia coli a Gram-negative rod bacteria that could be in the human large intestine cause of diarrhea. The study aimed to determine effect flower extract combination with tetracycline antibiotics using smallest concentration capable in...

OBJECTIVES This study was aimed to find out the minimum inhibitory concentration (MIC) of five essential oils against oral pathogens and to find out the minimum bactericidal concentration (MBC) and minimum fungicidal concentration (MFC) of five essential oils against oral pathogens. MATERIALS AND METHODS The antimicrobial activities by detecting MIC and MBC/MFC of five essential oils such as ...

Abstract Introduction: The aim of this study was to identify the antibacterial components in the ethanol extraction of Aloe vera against four clinically frequent pathogenic  bacteria. Materials and Methods: In this in-vitro study, Aloe vera extraction was prepared by dissolving 500 grams of the powder in 5L of 95% ethanol. The antibacterial activity of the extraction against Staphylococcus a...

BACKGROUND Blechnum orientale Linn. (Blechnaceae), a fern, is traditionally used in the treatment of various ailments, such as skin diseases, stomach pain, urinary bladder complaints, and also as a female contraceptive. Previously, we reported a strong radical scavenging activity, antibacterial activity and cytotoxicity against HT29 colon cancer cells by aqueous extract of B. orientale. OBJEC...

BACKGROUND Enteric fever is a major public health problem in India. The current treatment of choice is the fluoroquinolones. METHODS The minimum inhibitory concentration (MIC) of ciprofloxacin was determined by E-test, HIMEDIA HiComb MIC test and agar dilution. RESULTS An isolate of Salmonella enterica serovar Typhi (S. Typhi) from a case of enteric fever gave a ciprofloxacin MIC of 64 micr...

We have recently shown that 14alpha-demethylation-deficient cells of Candida albicans are subject to growth arrest by 0.24 M acetate in a yeast extract-peptone-glucose medium and that the minimum concentration of an azole antifungal agent required for total inhibition of sterol 14alpha-demethylation (MDIC for minimum demethylation-inhibitory concentration) is practically identical to its MIC de...

Abstract Cadmium-resistant bacteria that are used to remove cadmium (Cd) becoming increasingly of the most important and hygienic method. Resistant mechanisms involved in different ways, some them which can be removal techniques based on their molecular minimum inhibitory concentration (MIC). This review summarises recent improvements understanding by either intrinsically resistant or acquire r...
