Background: Oropharyngeal candidiasis is an important sign that may reflect a serious systemic disease, especially in immunocompromised patients who face the intolerable side effects of the available antifungal drugs. This necessitates the development of safe and effective natural components. Objectives: to evaluate the in vitro activities of both pomegranate peel and curcumin extracts and to compare them with nystatin and fluconazole drugs against Candida species. As far as we know, this is the first study comparing between the antifungal potency of both extracts. Methodology: Different Candida species were isolated from patients with oropharyngeal candidiasis. The antifungal activities of methanolic extracts of pomegranate peel and curcumin were tested by disc diffusion method. Both extracts were added to each of nystatin and fluconazole discs to measure their synergistic effects. Results: Highly significant synergism was detected between both extracts and each of antifungal drugs. Curcumin extract was more potent than pomegranate extract. Conclusion: When used in combination with nystatin and fluconazole, curcumin and pomegranate peel extracts are promising and effective anti-Candida agents.

Herbal therapies are used worldwide to treat a variety of health conditions, including dental conditions in veterinary medicine. In this context, the use of medicinal plant-based formulations as potential therapeutics and preventatives in veterinary dentistry is worth highlighting. The objective of the present study was to develop a mucoadhesive ointment formulation, named orabase, that contained pomegranate extract for use in the oral cavity of dogs, with the aim of improving their oral hygiene. The hydroalcoholic extracts of pomegranate peels was incorporated into the orabase in 3 different concentrations. The formulations were subjected to in vitro microbiological testing by a modified disc-diffusion method to study the susceptibility of microorganisms collected from the oral cavities of the dogs. The samples were taken from the buccal mucosa of dogs having the same management and diet. The most effective formulation was submitted to physicochemical tests to evaluate the functionality of the product, namely pH, swelling index, spreadability, and mechanical properties (hardness, cohesiveness, and adhesiveness). The formulation containing 25.0% w/w of the extract was considered most suitable for the intended use as it showed antiseptic activity and demonstrated a swelling index of approximately 35% in the first 20 minutes of the test, high spreadability, and suitable mechanical properties. The results suggest that the product obtained from pomegranate peel extract is a viable option for use to improve oral hygiene, helping to reduce the bacterial component of dental plaque in dogs.

The aim of this study was evaluated the Antimicrobial Activity of extraction of Datura innoxia (Seeds, leaves and roots). Datura innoxia Seeds, leaves and roots were collected to examine their antimicrobial activity. Extracts of different parts of the plant were tested against standard microorganisms by using the agar- well diffusion method. Extracts of methanol, and aqueous of seeds, leaves and roots were prepared and tested against four types of bacteria namely: Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Proteus vulgaris and two types of fungi namely: Aspergillus niger and Candida albicans. The methanolic and aqueous extracts of leaves showed high activities against fungi (A. niger) and less effect on the all bacteria. The methanolic extracts of seeds showed high activities against all organisms except fungi (C. albicanas), while the aqueous extracts of seeds showed no activity on the bacteria. All organisms were examined against known standard antibiotics and then compare the results of plant extracts with standard antibiotics. The results indicated that the antibacterial drug is less active than the plant extracts, while the antifungal drugs are more active than the plant extracts.

Introduction: Onychomycosis is a common fungal infection of nail. It may be caused by dermatophytes, non-dermatophytic moulds or yeasts involving nail bed, nail plate or matrix of nail. As the fungi show variable susceptibility to antifungal drugs and treatment requires long duration of antifungal therapy, so it’s prevalence as well as proper laboratory diagnosis and antifungal susceptibility testing is essential for effective therapy. Aim: To find the prevalence of onychomycosis with demography along with various aetiology and the suitable antifungal drugs used for treatment. Materials and Methods: For this prospective study, over a period of two years a total of 300 nail samples were processed in the Department of Microbiology at IMS and SUM Hospital, Bhubaneswar, Odisha, India. The wet mount for microscopic examination was prepared using 20% Potassium Hydroxide (KOH) and examined after overnight incubation. Culture was done in duplicate in Sabouraud’s Dextrose Agar (SDA) tubes; one with actidione and another without it and both were incubated at 25°C in Biological Oxygen Demand (BOD) incubator. Culture tubes growing yeasts were further subjected to speciation by germ tube test, culture on Chromogenic (CHROM) agar and on cornmeal agar. In-vitro antifungal susceptibility testing was performed against Candida species using disc diffusion method on Muller Hinton agar. Chi-square test was used for statistical analysis of the results. Results: Onychomycosis can affect a wide age group though seen commonly at 31-40 years equally in both male and females. Fingernail infection was observed mostly in female cases. It was caused by Candida species (66%), moulds (24%) and dermatophytes (10%) and out of Candida sp. C.albicans was the main culprit. Although all the Candida strains were susceptible to amphotericin B, still some of them showed resistance to the commonly used antifungals like fluconazole and itraconazole. Conclusion:Candida albicans was the most common aetiological agent which contributed for onychomycosis and showed a variable resistance pattern to the commonly used antifungals. Proper laboratory diagnosis and selection of antifungal drug is essential prior to institution of therapy for successful treatment of this disease.

Wound dressings can support healing by acting as physical barriers and drug delivery systems. The present study aimed to evaluate the biological activity of films containing pomegranate peel extract at 1.25% w/w prepared by the electrospinning technique for use as wound dressing. The extract was subjected to an in vitro cytotoxicity assay using fibroblasts. The formation of fibers was confirmed using scanning electron microscopy. Biocompatibility was analyzed by determining the hemolysis index, while the susceptibility of bacterial strains and a fungus was investigated using the disc diffusion method. The extract proved to be nontoxic with cell proliferation occurring at a concentration > 30 µg·mL-1. Photomicrograph images confirmed the formation of nanofibers. Films without or with the extract showed good hemocompatibility. The antimicrobial activity of films loaded with extract was demonstrated by the formation of zones of inhibition of Staphylococcus aureus, Staphylococcus epidermidis, and Candida albicans, suggesting that the release of the extract in the medium occurred at an adequate concentration to inhibit the proliferation of microorganisms. No zone of inhibition was observed for Escherichia coli. These results suggest that the film produced by electrospinning containing 1.25% w/w of the extract might serve as a bioactive wound dressing.

Giardiasis is a major diarrheal disease affecting approximately 2.5 million children annually in developing countries. Several studies have reported the resistance of Giardia lamblia (G. lamblia) to multiple drugs. Therefore, identifying an effective drug for giardiasis is a necessity. This study examined the antiparasitic effect of Punica granatum (pomegranate) and evaluated its therapeutic efficacy in rats infected with G. lamblia. In vitro study showed high efficacy of pomegranate peel ethanolic extract in killing G. lamblia cysts as demonstrated by eosin vital staining. We showed that treating infected rats with pomegranate extract resulted in a marked reduction in the mean number of G. lamblia cysts and trophozoites in feces and intestine respectively. Interestingly, the number of G. lamblia trophozoites and cysts were significantly lower in the pomegranate extract-treated group compared to the metronidazole-positive control group. Moreover, pomegranate extract treatment significantly induced nitric oxide (NO) and reduced serum IL-6 and TNF-α, compared to infected untreated rats. Histological and scanning electron microscopy (SEM) examination of the jejunum and duodenum of pomegranate extract-treated animals confirmed the antiparasitic effect of the extract, and demonstrated the restoration of villi structure with reduction of villi atrophy, decreased infiltration of lymphocytes, and protection of intestinal cells from apoptotic cell death. In conclusion, our data show that the pomegranate peel extract is effective in controlling G. lamblia infections, which suggests that it could be a viable treatment option for giardiasis.

Excoecaria agallocha plant (Leaves) was analyzed to explore In Vitro antimicrobial and membrane stabilizing activities as a crude methanolic extract. Antimicrobial activity was performed against a wide range of Gram positive(+Ve) and Gram negative(-Ve) bacteria by using disc diffusion method and various methanolic extracts of leaves of E.agallocha was tested for determining membrane stabilizing activity at hypotonic solution and heat induce condition and standard acetyl salicylic acid (0.10 mg/mL) was employed as standard. the zones of inhibition created was found to be 1.3 cm at a concentration of 100 µL/ disc in case of Gram negative(-Ve) bacteria Salmonella typhi. The results obtained were compared with that of a standard Ampicillin (10 µL) and imipenem (10µL), penicillin (10µl), cefoxitine(30µl). Crude methanolic extract of 10mg/ml concentration showed maximum value of 17.67±0.0102 and 18.92±0.086% respectively under hypotonic solution and heat induced condition. Thus the result suggest that, crude methanolic extracts of E.agallocha possessed slight to moderate antimicrobial and membrane stabilizing properties.

Histoplasma capsulatum is a dimorphic fungal pathogen endemic to the midwestern and southern United States. It causes mycoses ranging from subclinical respiratory infections to severe systemic disease, and is of particular concern for immunocompromised patients in endemic areas. Clinical management of histoplasmosis relies on protracted regimens of antifungal drugs whose effectiveness can be limited by toxicity. In this study, we hypothesize that conserved biochemical signaling pathways in the eukaryotic domain can be leveraged to repurpose kinase inhibitors as antifungal compounds. We conducted a screen of two kinase inhibitor libraries to identify compounds inhibiting the growth of Histoplasma capsulatum in the pathogenic yeast form. Our approach identified seven compounds with an elongated hydrophobic polyaromatic structure, five of which share a molecular motif including a urea unit linking a halogenated benzene ring and a para-substituted polyaromatic group. The top hits include the cancer therapeutic Sorafenib, which inhibits growth of Histoplasma in vitro and in a macrophage infection model with low host cell cytotoxicity. Our results reveal the possibility of repurposing Sorafenib or derivatives thereof as therapy for histoplasmosis, and suggest that repurposing of libraries developed for human cellular targets may be a fruitful source of antifungal discovery.
