Aim. To conduct a comparative assessment of the fungicidal activity of widespread and endemic species of the genus Allium growing in Tajikistan.Material and methods. The initial ethanol extracts were obtained from fresh plants of 15 onion species from different climatic and geographical regions of the Republic of Tajikistan. The antifungal activity of species of the genus Allium was studied against the yeast-like fungi Candida albicans using the disk diffusion method.Results: The highest fungicidal effect on the reference strain of Candida albicans was demonstrated by alcoholic extracts of the widespread wild species A. elatum Regel, A. oschaninii O. Fedtsch, A. obliguum L, and endemic species A. shugnanicum Vved. Low antifungal activity was found in extracts of 4 widespread wild-growing plant species - A. altaicum Pall, A. suworowii Regel, A. carolinianum DC, A.longicuspis L.Conclusions. The antifungal activity of 13 species of widespread wild-growing and 2 endemic species (A.shugnanicum Vved and A. pamiricum Wendelbo) was studied for the first time. A. elatum Regel, A. oschaninii O. Fedtsch, A. obliguum L, and endemic species A. shugnanicum Vved had a maximal inhibitory effect on the yeast fungus. The extracts obtained from the bulbs and seeds of the studied plants are characterized by the highest antifungal activity.

Background. Echinops kebericho is an endemic medicinal plant in Ethiopia widely used in the treatment of infectious and noninfectious diseases. Essential oils are known for their antibacterial, antifungal, antiviral, insecticidal, and antioxidant properties. This study evaluated the antifungal activity of essential oil from E. kebericho against four common pathogenic fungi and two standard strains. Methods. The essential oil was obtained by hydrodistillation. The antifungal screening was done by agar well diffusion method. Minimal inhibitory concentrations (MICs) were determined by broth microdilution. Minimal fungicidal concentrations (MFCs) were determined by subculturing fungal strains with no visible growth onto a Sabouraud dextrose agar (SDA) plate. Results. Candida albicans and Cryptococcus neoformans were highly sensitive while Aspergillus flavus did not show sensitivity up to 1 mg/ml of essential oil; MICs ranged from 0.083 mg/ml to 0.208 mg/ml. Concentration and fungal species showed significant dose-dependent associations ( p < 0.0001 ) with antifungal activity. The MICs of essential oil were comparable to those of the standard drug (fluconazole) against C. glabrata and C. krusei. The lowest MFC of the essential oil was observed against Candida parapsilosis (0.145 mg/ml) while the highest MFC was against Candida krusei (0.667 mg/ml). Conclusion. Echinops kebericho essential oil showed noteworthy antifungal activity against Cryptococcus neoformans, Candida albicans, and Candida glabrata and could be a potential candidate for further antifungal drug development.

(1) Background: Few antifungal drugs are currently available, and drug-resistant strains have rapidly emerged. Thus, the aim of this study is to evaluate the effectiveness of the antifungal activity from a combinational treatment of chitosan with a clinical antifungal drug on Candida albicans and Candida tropicalis. (2) Methods: Minimum inhibitory concentration (MIC) tests, checkerboard assays, and disc assays were employed to determine the inhibitory effect of chitosan with or without other antifungal drugs on C. albicans and C. tropicalis. (3) Results: Treatment with chitosan in combination with fluconazole showed a great synergistic fungicidal effect against C. albicans and C. tropicalis, but an indifferent effect on antifungal activity when challenged with chitosan-amphotericin B or chitosan-caspofungin simultaneously. Furthermore, the combination of chitosan and fluconazole was effective against drug-resistant strains. (4) Conclusions: These findings provide strong evidence that chitosan in combination with fluconazole is a promising therapy against two Candida species and its drug-resistant strains.

Abstract Haemophilus parasuis (H. parasuis) is the etiological agent of Glässer's disease and brings great economic losses to the pig industry. The goal of our research is to reveal the serotypes of H. parasuis isolated from large-scale pig farms in China from 2016 to 2018. From 2016 to 2018, 8153 H. parasuis field strains were isolated from 14610 clinical samples of sick pigs with clinical symptoms from 26 provinces and cities of China. Among them, 1386 strains were identified as H. parasuis by PCR, and the isolation rate was 9.49%. Through multiplex PCR, we showed that type 5/12 and type 4 strains had the highest separation rate, followed by type 13 and type 14 strains. Using disk diffusion method, we found cephalosporin antibiotics and peptide antibiotics all had good inhibitory effect on H. parasuis. Our conclusion may play a positive role in the prevention and treatment of H. parasuis.

Researchers have been trying to develop new broad-spectrum antibiotics against the infectious diseases caused by bacteria, fungi, viruses, and parasites for many decades. Prolonged usage of the antibiotics has led to the emergence of drug resistance among bacteria; therefore, there is a tremendous need for novel antimicrobial agents from different sources such as plants which are used in traditional medicine. The aim of this study was to evaluate antibacterial effect of <em>Achillea tenuifolia</em>.<em> </em>The plant material was extracted by maceration method using methanol three times at room temperature. The extract was concentrated after removing the solvent by rotary evaporator and then lyophilized using freeze dryer. Inhibitory effect of the extract was examined against four standard bacteria strains and two isolated strains from diseased hen using disk diffusion method and microdilution method to evaluate their inhibition zone diameter (IZD) and minimum inhibitory concentration (MIC), respectively. The results showed that the extract of the plant was active against standard strains including <em>Escherichia coli</em>, <em>Pseudomonas aeruginosa</em>, <em>Staphylococcus aureus </em>and <em>Enterococcus faecalis </em>with IZDs of 10.3±0.5, 14±0.0, 12±0.0 and 11.6±0.5, respectively.<strong> </strong>However, growths of isolated strains were not inhibited in the presence of the extract. Although, the growths of isolated strains were not inhibited by the plant extract, the standard strains were moderately susceptible to the extract; among those <em>P. aeroginosa</em> was more sensible than other tested strains
