Abstract

Highlights: Most urinary tract infections are caused by Gram-negative bacteria with E. coli being the most common bacteria. Antibiotics with the highest susceptibility for Gram-negative bacteria were ertapenem, meropenem, amikacin, and imipenem. Antibiotics with the highest susceptibility for Gram-positive bacteria mainly were susceptible to chloramphenicol,streptomycin, vancomycin, rifampin, tigecycline,  teicoplanin, and ampicillin.   Abstract: Urinary tract infection (UTI) is one of the most common bacterial infections. Inappropriate antibiotic use for UTI treatment may lead to antibiotic resistance. This study aimed to provide an updated bacterial and antibiogram profile from urine specimens of patients diagnosed with UTI. This study was a retrospective study using urine culture and antibiotic susceptibility test results obtained from Clinical Microbiology Laboratory in a tertiary general hospital in Surabaya, Indonesia for a two-month period patients. Most aged more than and/or equal to 59 years, in both sexes. Gram-negative bacteria, particularly , was being the most between June to July 2019. There were 215 patients with significant urine culture results of 54.4% from Escherichia coli female bacteria were carbapenem antibiotics and amikacin, while teicoplanin and vancomycin were some antibiotics susceptible to gramcommon bacteria that caused UTI, followed by K. pneumoniae. Some antibiotics with the highest susceptibility to gram-negative positive bacteria. This study result indicated that there was an urge to conduct local antibiogram profile investigation due to the low susceptibilities shown in recent empirical therapy recommendations, such as trimethoprim sulfamethoxazole, fluoroquinolone, nitrofurantoin, and fosfomycin.

Abstract

Highlights: 1. A study on the medical benefits of Selaginella plana has significant academic value due to its extensive traditional usage among the Moluccan people as a medicinal remedy, especially for its antifungal properties.2. The findings of this study will allow further screening to determine the mechanism of action of bioactive compounds in inhibiting the growth of Candida albicans   Abstract Candidiasis is an opportunistic infection caused by Candida albicans. This infection commonly affects the skin, oral mucosa, vagina, and gastrointestinal tract. Excessive use of azole antifungals in the treatment of Candida albicans infections can lead to the development of resistance. Therefore, it is necessary to explore alternative treatments using medicinal plants such as Selaginella plana, commonly referred to as “rutu-rutu” in a local language spoken across Maluku, Indonesia. Selaginella plana contains active compounds belonging to various chemical classes, including terpenoids, steroids, flavonoids, and saponins. This study aimed to determine the ability of Selaginella plana extract as an antifungal agent against Candida albicans by evaluating its inhibitory and antifungal effects. This study used an actual experimental design and broth dilution method. The research methodology involved the extraction of Selaginella plana using a solvent of 96% ethanol. The extract was then prepared in various concentrations, i.e., 100%, 50%, 25%, 12.5%, 6.25%, and 3.125%. Additionally, ketoconazole and distilled water were included in the experiment for the positive and negative controls, respectively. The results of this study demonstrated that Selaginella plana extract inhibited the growth of Candida albicans when administered starting at a concentration of 12.5%. However, the antifungal potential of Selaginella plana extract that induced cell death was only observed at a concentration of 100%. The fungicidal activity was exclusively identified in the undiluted, pure extract. The inhibitory and cytotoxic effects of Selaginella plana on Candida albicans cells were attributed to the presence of bioactive compounds in Selaginella plana, including flavonoids, tannins, terpenoids, and saponins. These bioactive compounds had the ability to inhibit cell growth by altering membrane permeability, causing mitochondrial dysfunction, and disrupting ergosterol biosynthesis. It can be concluded that Selaginella plana extract can act as a fungistatic agent against the proliferation of Candida albicans.
