Abstract
BACKGROUND Fusarium species are opportunistic human pathogens that remarkably cause fungal infections ranging from superficial to fatal invasive disseminated infections. Fusarium species are notoriously resistant to the majority of antifungal agents. OBJECTIVES Therefore, detailed studies regarding in vitro susceptibility are required and may lead to a better prognosis of severe infections. METHODS We evaluated 25 antifungal drugs in vitro against 282 clinical and environmental Fusarium isolates. RESULTS Fusarium species demonstrated high MICs/MECs values to the most commonly used antifungal drugs in clinical practice. The geometric mean (GM) MICs for luliconazole (0.004 μg/ml) and lanoconazole (0.012 μg/ml) were the lowest, followed by efinaconazole (0.98 μg/ml) and amphotericin B (1.04 μg/ml). CONCLUSIONS Efinaconazole, a novel triazole, may be a promising candidate for the treatment of superficial Fusarium infections. Furthermore, the development of systemic formulations of these drugs as well as further in vitro and in vivo investigations could aid in the treatment of systemic fusariosis.

Abstract
Background and Purpose The hospital environment was reported as a real habitat for different microorganisms, especially mold fungi. On the other hand, these opportunistic fungi were considered hospital-acquired mold infections in patients with weak immune status. Therefore, this multi-center study aimed to evaluate 23 hospitals in 18 provinces of Iran for fungal contamination sources. Materials and Methods In total, 43 opened Petri plates and 213 surface samples were collected throughout different wards of 23 hospitals. All collected samples were inoculated into Sabouraud Dextrose Agar containing Chloramphenicol (SC), and the plates were then incubated at 27-30ºC for 7-14 days. Results A total of 210 fungal colonies from equipment (162, 77.1%) and air (48, 22.9%) were identified. The most predominant isolated genus was Aspergillus (47.5%), followed by Rhizopus (14.2%), Mucor (11.7%), and Cladosporium (9.2%). Aspergillus (39.5%), Cladosporium (16.6%), as well as Penicillium and Sterile hyphae (10.4% each), were the most isolates from the air samples. Moreover, intensive care units (38.5%) and operating rooms (21.9%) had the highest number of isolated fungal colonies. Out of 256 collected samples from equipment and air, 163 (63.7%) were positive for fungal growth. The rate of fungal contamination in instrument and air samples was 128/213 (60.1%) and 35/43 (81.2%), respectively. Among the isolated species of Aspergillus, A. flavus complex (38/96, 39.6%), A. niger complex (31/96, 32.3%), and A. fumigatus complex (15/96, 15.6%) were the commonest species. Conclusion According to our findings, in addition to air, equipment and instrument should be considered among the significant sources of fungal contamination in the indoor environment of hospitals.

Abstract
Background and Purpose: Vulvovaginal candidiasis is considered the second most prevalent gynecologic infection among women and one of the main reasons for referring to a gynecologist. During recent decades, probiotic usage has been defined as one of the therapeutic regimens for vaginal candidiasis management, but these findings were controversial. The current study was conducted to determine the effect of fluconazole plus vaginal and oral probiotics supplementation on clinical and mycological improvement of vaginal candidiasis concomitant with antifungal susceptibility of Candida species to fluconazole. Materials and Methods: This double-blind, randomized, placebo-controlled trial was conducted on 76 women with vaginal candidiasis admitted to Naghavi and Imam Reza Gynecology Clinics in Kashan,
Central Iran, from July 2017 to March 2020. Patients were diagnosed according to vaginal candidiasis symptoms and positive culture for Candida species.
The patients were divided into two groups; one of them received fluconazole plus vaginal and oral probiotics, while the other one received fluconazole with placebo.
The clinical and mycological findings were recorded before and after the treatment. In vitro, the fluconazole susceptibility test was determined by the microdilution method
according to the Clinical and Laboratory Standards Institute (M27-A3) for the baseline Candida isolates. Conclusion: Based on the findings, 35 days after the intervention, a significant reduction was reported in vaginal candidiasis symptoms in the probiotics supplementation group.
Although probiotics supplementation therapy was a better mycological cure, compared to the fluconazole with the placebo group, this difference was not significant (68.4% vs. 46.9%, P=0.184).
Exclusion of resistant and susceptible dose-dependent strain in the regression model demonstrated a significant reduction in positive culture probiotics in the supplementation group. Results: Oral and vaginal supplementation with probiotics for 4 weeks played a significant role in the elimination of vaginal candidiasis symptoms. Adjustment of clinical and mycological responses with drug resistance patterns of patients could open a promising horizon for probiotics consumption as a complementary treatment.

Abstract
Aspergillus clavatus is a common environmental species known to cause occupational allergic disease in grain handlers. We have recently observed azole-resistant isolates of this fungus as a cause of onychomycosis. To further characterize the cause of resistance, the genes encoding 14 α-sterol demethylase enzyme (cyp51A and cyp51B) were characterized and analyzed in 9 ITC-susceptible isolates and 6 isolates with high minimum inhibitory concentrations (MICs) of clinical (nail and sputum) and environmental A. clavatus strains. We found that six isolates with itraconazole MIC >16 mg/L demonstrated nonsynonymous mutations, including V51I, L378P, E483K, and E506G, and synonymous mutations, including F53F, A186A, Q276Q, and H359H. Moreover, P486S was detected in five strains with ITR MIC >16 mg/L. One mutation, F324S, was detected in an isolate with posaconazole MIC >16 mg/L. The effect of E483K and P486S mutations of CYP51A on azole resistance was further investigated using homology modeling and molecular dynamics. We found that E483K and P486S mutations were located near the ligand access channel of CYP51A that could partly lead to narrowing the entry of the ligand access channels. Therefore, we concluded that E483K and P486S mutations may potentially contribute to the limited access of inhibitors to the binding pocket and therefore confer resistance to azole agents.

Abstract
Mucormycosis is a devastating infection caused by Mucoralean fungi (Mucormycotina, Mucorales). Data concerning the global epidemiology of mucormycosis are scarce and little is known about the characteristics of mucormycosis in Iran. In this study, we aimed to understand the distribution of this infection in Iran retrospectively and to ascertain whether the patterns of infection are associated with specific host factors or not. A total of 208 cases were included in this study occurring during 2008-2014 and were validated according to (EORTC/MSG) criteria. A rising trend as significant increase from 9.7% in 2008 to 23.7% in 2014 was observed. The majority of patients were female (51.4%) with median age of 50 and the infections were seen mostly in autumn season (39.4%). Diabetes mellitus (75.4%) was the most common underlying condition and sinus involvement (86%) was the mostly affected site of infection. Amphotericin B (AmB) was the drug of choice for the majority of cases. Sixty four isolates did not show any growth in the lab and only 21 cases were evaluated by ITS sequencing, among them; Rhizopus arrhizus var. arrhizus was the dominant species. Considering the high mortality rate of mucormycosis, early and accurate diagnosis, with the aid of molecular methods may provide accurate treatments and improve the survival rate. Therefore, increased monitoring and awareness of this life-threatening disease is critical.

Abstract
To date, there has been no comprehensive review of the epidemiology, risk factors, species distribution, and outcomes of candidemia in Iran. This study aimed to perform a systematic review and meta-analysis of all reported candidemia cases in Iran until December 2015. The review process occurred in three steps, namely a literature search, data extraction and statistical analyses. After a comprehensive literature search, we identified 55 cases. The mean age of patients was 46.80±24.30 years (range 1-81 years). The main risk factors for candidemia were surgery and burns (23.6%), followed by malignancies (20%), use of broad-spectrum antibiotics (18.2%), and diabetes (7.3%). Candida parapsilosis (n=17, 30.8%) was the leading agent, followed by Candida albicans (n=15, 27.3%), Candida glabrata (n=10, 18.2%), and Candida tropicalis (n=8, 14.5%). The frequencies of candidemia cases due to C. glabrata, C. parapsilosis, and C. albicans were significantly higher among patients aged>60, 21-40, and 41-60 years, respectively. Comparison of risk factors for candidemia by multiple logistic regression showed that one of the most important risk factors was surgery (OR: 4.245; 95% CI: 1.141-15.789; P=0.031). The outcome was recorded in only 19 cases and 13 of those patients (68.4%) expired. This study confirms that knowledge of the local epidemiology is important when conducting surveillance studies to prevent and control candidemia and will be of interest for antifungal stewardship.

Abstract
Background and Purpose: Candida species are considered a common cause of fungal blood stream infections, which are associated with considerable mortality and morbidity rates, especially in the admitted and immunocompromised patients. Despite the increase in new and available antifungal agents, the emergence of resistant strains is growing. Regarding this, the aim of the present study was to assess the fungal epidemiology of candidemia and the antifungal susceptibility patterns against five current antifungal agents among the patients with prolonged fever, who were admitted to Beheshti Educational Hospital, Kashan, Iran. Materials and Methods: This cross-sectional study was conducted on 253 hospitalized patients with prolonged fever despite receiving broad-spectrum antibiotic therapy. Blood samples were collected aseptically, and then cultured using an automated blood culture system and conventional broth culture bottle. Candida isolates were identified at species level using morphological and physiological properties and produced color on the CHROMagar Candida. Furthermore, the antifungal susceptibility testing was performed using (CLSI M27-A3 and CLSI M27-S4) broth microdilution methods. Results: The most positive cultures were detected by the automated blood culture system. C.albicans (%50) was the most prevalent species, followed by C. glabrata (%40), and C. parapsilosis, (%10) respectively .The mortality rate was high (%60) and most patients with candidemia were admitted to the Intensive Care Unit and Neonatal Intensive Care Unit. All isolates were susceptible to amphotericin B, while the highest resistance belonged to caspofungin. Conclusion: In this study, high resistance was reported, especially for caspofungin, which can be regarded as the emergence of caspofungin-resistant strains. Regarding this, the establishment of a surveillance and prevention program for the reduction of the emergence of resistant species is necessary.

Abstract
Aspergillus flavus is the second leading cause of invasive and non-invasive aspergillosis, as well as the most common cause of fungal sinusitis, cutaneous infections, and endophthalmitis in tropical countries. Since resistance to antifungal agents has been observed in patients, susceptibility testing is helpful in defining the activity spectrum of antifungals and determining the appropriate drug for treatment. A collection of 199 clinical and environmental strains of Aspergillus flavus consisted of clinical (n=171) and environmental (n=28) were verified by DNA sequencing of the partial b-tubulin gene. MICs of amphotericin B, itraconazole, voriconazole, posaconazole, and MEC of caspofungin were determined in accordance with the Clinical and Laboratory Standards Institute M38-A2 document. Caspofungin, followed by posaconazole, exhibited the lowest minimum inhibitory concentrations (MIC). All isolates had caspofungin MEC90 (0.063μg/ml) lower than the epidemiologic cutoff values, and 3.5% of the isolates had amphotericin B MIC higher than the epidemiologic cutoff values. However, their clinical effectiveness in the treatment of A. flavus infection remains to be determined.

Abstract
Background: Malassezia species are lipophilic yeasts found on the skin surface of humans and other warm-blooded vertebrates. It is associated with various human diseases, especially pityriasis versicolor, which is a chronic superficial skin disorder. Objectives: The aim of the present study was to identify Malassezia species isolated from patients’ samples affected by pityriasis versicolor, using molecular methods in Kashan, Iran. Patients and Methods: A total of 140 subjects, suspected of having pityriasis versicolor from Kashan, were clinically diagnosed and then confirmed by direct microscopic examination. The scraped skin specimens were inoculated in modified Dixon’s medium. DNA was extracted from the colonies and PCR amplification was carried out for the 26s rDNA region. PCR products were used to further restriction fragment length polymorphism by CfoI enzyme. Results: Direct examination was positive in 93.3% of suspected pityriasis versicolor lesions. No statistically significant difference was observed in the frequency of Malassezia species between women and men. The highest prevalence of tinea versicolor was seen in patients 21–30 years-of-age. No difference could be seen in the frequency of Malassezia species depending on the age of the patients. In total, 65% of patients with pityriasis versicolor had hyperhidrosis. The most commonly isolated Malassezia species in the pityriasis versicolor lesions were; Malassezia globosa (66%), M. furfur (26%), M. restricta (3%), M. sympodialis (3%), and M. slooffiae (2%). Malassezia species were mainly isolated from the neck and chest. Conclusions: This study showed M. globosa to be the most common Malassezia species isolated from Malassezia skin disorders in Kashan, Iran. The PCR-RFLP method was useful in the rapid identification of the Malassezia species. By using these methods, the detection and identification of individual Malassezia species from clinical samples was substantially easier.

Abstract
Mucormycosis is an invasive fungal infection caused by filamentous fungi of the Mucoraceae family. The genera most commonly responsible are Mucor or Rhizopus. The disease occurs mostly in association with diabetic ketoacidosis. Mucormycosis has an extremely high death rate even when aggressive surgery is done. Death rates range from 25-85% depending on the body area involved. A case of rhinocerebral mucormycosis in a 65-year-old diabetic male patient typically presenting as headache, especially in parietal and frontal lobes, with nose and left eye discharge. After clinical and laboratory examination, mucormycosis was diagnosed, and Rhizopus oryzae was isolated. Systemic therapy with amphotericin B administered intravenously then replaced by posaconazole by a combination of aggressive surgery. The patient was treated and followed up for one year. We emphasize the importance of early detection and aggressive treatment in the management of this fatal disease.

Abstract
Due to the epidemiological alteration in distribution of Candida species as well as significant increasing trend of either intrinsic or acquired in resistance of some of these fungi, the precise identification of Candida species is necessary for effective antifungal therapy and also for prevention of nosocomial infections. PCR-RFLP method is indicated to be a reliable, rapid and simple technique which is able to differentiate the Candida species. In the present study, we applied this method to evaluate the distribution of Candida species in patients affected with cutaneous candidiasis in the Guilan province. 896 clinical cutaneous samples were collected from different parts of skin and nail of suspected patients referred to clinical centers all over the Guilan province during 24 months. Samples were examined directly with 15% KOH and cultured on fungal specific media. Genomic DNA was extracted and the restriction enzyme Msp1 was applied for polymorphism analysis. Totally, 47 yeast strains were successfully isolated from different clinical samples and identified by conventional as well as PCR-RFLP methods. The results indicated that Candida albicans (36.17%) was the most frequent species followed by C. parapsilosis (25.53%), C. tropicalis (19.14%), C. guilliermondii (14.89%), C. famata (2.12%) and C. krusei (2.12%). Female finger nails were the most common location to be affected by Candida species. In conclusion, PCR-RFLP method was successfully used for recognition of clinical Candida species within the Guilan province and obtained results revealed C. albicans as the predominant causative agent of cutaneous candidiasis. However, distribution of other Candida species did not completely consist with the reported distribution of Candida species in other parts of Iran with different climate to the Guilan province.

Abstract
Schizophillum commune has been increasingly reported from allergic bronchopulmonary mycosis (ABPM) as well as fungus ball, brain abscess and several cases of maxillary or allergic fungal sinusitis. In the present study, we reported a case of fungus ball type pansinusitis from a 32-year-old woman in Iran. According to computed tomography (CT) scan, fungus ball type pan-sinusitis was likely to be the first diagnosis. Mycological examination revealed hyaline hyphae with small projection and also clamp connection structures on PDA medium. To identify the obtained isolate properly, molecular analysis of the internal transcribed spacer region was performed and indicated that the causing agent of the infection is surely Schizophillum commune. The patient completely recovered after surgical endoscopic operation and consequent post-operation MRI revealed clearance of sinuses.

Abstract
BACKGROUND The aim of this study was identification of the epidemiology of Prototheca zopfii species from the milk samples of dairy cattle in Isfahan, central Iran. METHODS Milk samples were obtained from 230 dairy cattle, 130 with and 100 without mastitis, in Isfahan. The samples were cultured in Prototheca Isolation Medium (PIM) and Sabouraud's dextrose agar. All P. zopfii isolates were identified by morphological and biochemical methods. Then, as a confirmatory test they were examined by genotype-specific PCR. RESULTS Four P. zopfii strains (3.07%) were isolated from the 130 samples of dairy cattle with clinical mastitis and there was no isolation from totally 100 samples of healthy bovines without mastitis. Specific PCR product (about 946 bp) was detected in four isolates. CONCLUSION It seems that P. zopfii genotype II plays a key role in affecting bovine mastitis that confirmed other previous studies. Our study was the first, which identified the Prototheca species by traditional and molecular methods in Iran and Middle East as well.
