Abstract Objective: Yeasts are opportunistic microorganisms can cause human fungal infection among immunocompromised patients. This study aimed to identify Candida species and uncommon yeasts obtained from clinical specimens in Kashani university hospital and Shefa Lab as a referral medical mycology laboratory, in Isfahan, Iran, by combination of various molecular techniques. Results: A total of 202 yeast strains were isolated from 341 clinical samples between February 2017 to May 2019. All clinical isolates were identified using phenotypic and molecular tests. PCR-RFLP, duplex-PCR, multiplex-PCR, and PCR-sequencing were applied for molecular identification of yeasts. The most clinical samples were obtained from urine (66.8%), nail (9.4%), bronchoalveolar lavage (5.9%), sore (4.4%), and blood (3.9%). One hundred and twenty-one Candida species were identified as non- albicans against 76 Candida albicans. Trichosporon asahii, and Pichia terricola were uncommon non- Candida yeasts isolated from urine samples. For the first time, we isolated P. terricola as etiologic agent of urinary tract infection in a pregnant female. Since non- albicans Candida species and non- Candida yeasts have various virulence factors and antifungal susceptibility profile, precise molecular identification can help us to reach to the advantageous strategies for treatment of these fungal infections.

Introduction: The occurrence of invasive fungal infections has increased significantly worldwide, premature infants in Neonatal Intensive Care Unit (NICU) along with other risk factors are at particular risk of these invasive fungal infections which lead to fungal septicaemia in newborns. Candidaemia is the most common form of invasive candidiasis associated with an unacceptably high mortality rates. Candida colonisation in neonates is considered the first step towards developing neonatal sepsis. Aim: To determine the prevalence of Candida colonisation and its characterisation among neonates admitted in NICU. Materials and Methods: The present study was a prospective cross-sectional study with 150 neonates included in the study. Swabs were taken from four different sites of each neonate and inoculated on Chocolate agar and Sabouraud’s Dextrose Agar (SDA) and incubated at 37°C for seven days. Candida species isolated were confirmed by gram stain, germ tube test, growth on Chromogenic (CHROM) agar and cornmeal agar. Statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 11.0. Results: A total of 32 (21.3%) neonates had Candida colonisation. Twenty two (68.7%) were low birth weight and 24 (75%) were born premature. Perineum was the most common (56%) site of colonisation. Among Candida isolates, Candida tropicalis(63%) was the commonest followed by Candida parapsilosis(25%) and Candida glabrata and Candida albicans (6%). The risk factors identified were low birth weight, premature birth, use of antibiotics. Conclusion: Colonisation of preterm and low birth weight neonates by Candida species is a major risk factor and needs attention to avoid dissemination and life threatening infection.

Background and Purpose: Opportunistic fungal infections have been on a growingtrend since the last two decades. Among the opportunistic fungal agents, Candidaspecies, Cryptococcus neoformans, and Aspergillus fumigatus account for most of thelife-threatening infections in immunocompromised individuals. Regarding this, thepresent study aimed to investigate the molecular identification and antifungalsusceptibility pattern of Candida species isolated from HIV-infected patients.Materials and Methods: This study was conducted on 80 clinical samples collectedfrom HIV-infected patients with suspected candidiasis referring to Tagore MedicalCollege and Hospital, Rathinamangalam and Government Hospital of ThoracicMedicine, in Chennai, India, for 18 months (i.e., May 2016-December 2017). Phenotypicand molecular identification was accomplished using internal transcribed spacer region 1(ITS1) and ITS4 primers. The antifungal susceptibility pattern of the isolates against fourantifungal agents was also determined by both disk diffusion and broth dilution methods.Results: In the present study, the prevalence of candidiasis was obtained as 75% (n=60).Candida tropicalis was the predominant identified species. All the emerging species(i.e., Kodamaea ohmeri, Hanseniaspora opuntiae, and C. orthopsilosis) were identifiedthrough molecular identification since the phenotypic identification was inconclusive. Interms of the susceptibility pattern, 63.3% and 18.3% of the isolates were resistant tofluconazole and voriconazole, respectively. Candida albicans was also found to beresistant to amphotericin B.Conclusion: Molecular assay led to the identification of K. ohmeri, H. opuntiae, and C.orthopsilosis, which were multidrug-resistant. This study highlighted the need for theprompt and timely identification of clinical yeast isolates given the emergence of manyrare species and their capability of causing life-threatening infections and outbreaks. Inthe laboratories where molecular diagnostic methods are not available, alternativeservices of reference laboratories can be utilized as cost-effective measures. With regardto the growing prevalence of antifungal drug resistance, antifungal susceptibility testingshould be made mandatory for effective patient management.

Background. Candida species is usually a commensal fungus residing in the vagina, in about 30 %–50 % of healthy adults and remains the most common agent isolated from clinical samples of patients diagnosed with vulvovaginal candidiasis (VVC). Culture is not recommended for all patients on a routine basis but is informative for the exclusion of non-albicans infections resistant to azoles, or recurrent VVC. Identification of Candida species and antifungal susceptibility testing are key elements in the correct management of recurrent VVC. The authors of this paper aimed to study the spectrum of pathogenic Candida species. The antifungal sensitivity patterns of the isolated strains during the years 2017-2019 are also presented. Material and methods. A descriptive study of Candida species distribution and antifungal susceptibility profile was performed. Identification of isolated Candida species was performed by the MALDI-TOF MS, bacterial strains by Vitek 2 automated system (BioMérieux) and antifungal susceptibility profiles by Fungitest (Bio-Rad). Results. Of the 1030 recovered strains, C. albicans species predominated - 83.8% and Candida non albicans -16.2%. The most common species of the Candida non-albicans, were C.glabrata (7.5%). Also, it was observed that in 56.6% of the cases C. albicans presented bacterial associations. The most common microbial association was C. albicans and S.aureus (26.6%), followed by C. albicans and E.coli (20.8%). Candida spp. showed moderate antifungal resistance. The resistance rate of C. albicans isolates to miconazole, fluconazole and itraconazole was 25.5%, 17.0% and 11.4% compared to non-albicans Candida strains which showed a resistance rate of 10,8%, 14.4% and 10%, respectively. Conclusions. C. albicans is the most frequently isolated species among patients with VVC, but there is also an increase share of non-albicans Candida species such as C. glabrata. C. albicans isolates showed higher indices of resistance, than Candida non-albicans.

Candidiasis has become increasingly widespread in the community alongside with the developing resistance of Candida sp. to some antifungals. A prevalence study in the present research is required to surveil the distribution of Candida-related infections to administrate the appropriate antifungal treatments. The objective of this research was to determine the species distribution of candidiasis with their antifungal susceptibility isolated from clinical specimens at the Zainoel Abidin Hospital (ZAH) Banda Aceh, Indonesia. The clinical specimens were from inpatients and outpatients in the hospital during January to June 2019. The identification of Candida species and antifungal sensitivity assay were conducted by using VITEK® 2 Compact. Of a total of 68 isolates, there were six species of Candida with the highest species prevalence was Candida tropicalis (52.94%). Additionally, the highest prevalence of candidiasis came from urine specimen (54.41%) and mostly from inpatients in the internal medicine unit (54.41%). Candidiasis occurred predominantly in men (58.82%) and during adulthood (55.88%). The antibiogram of Candida sp. shows a high percentage of sensitivity towards some antifungals including fluconazole (100%), voriconazole (100%), caspofungin (100%), micafungin (100%), amphotericin B (99.5%), and flucytosine (100%). From this result, it can be concluded that candidiasis cases in the ZAH Banda Aceh, Indonesia has prevalently occurred with the few antifungal therapies for candidiasis of were still effective empirically and definitively. This is an initial study of Candida prevalence within different clinical samples in Banda Aceh and the study is expected to be a basis for prevention and control of Candida-related infections in the area.

Background and Purpose: The aim of the current study was to investigate the epidemiology of vulvovaginal candidiasis (VVC) and recurrent VVC (RVVC), as well as the antifungal susceptibility patterns of Candida species isolates.Materials and Methods: A cross-sectional study was carried out on 260 women suspected of VVC from February 2017 to January 2018. In order to identify Candida species isolated from the genital tracts, the isolates were subjected to polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) using enzymes Msp I and sequencing. Moreover, antifungal susceptibility testing was performed according to the Clinical and Laboratory Standards Institute guidelines (M27-A3).Results: Out of 250 subjects, 75 (28.8%) patients were affected by VVC, out of whom 15 (20%) cases had RVVC. Among the Candida species, C. albicans was the most common species (42/95; 44.21%), followed by C. lusitaniae (18/95; 18.95%), C. parapsilosis (13/95; 13.69%),  C. glabrata (8/95; 8.42%), C. kefyr (6/95; 6.31%), C. famata (5/95; 5.26%), C. africana (2/95; 2.11%), and C. orthopsilosis (1/95; 1.05%), respectively. Multiple Candida species were observed in 28% (21/75) of the patients. Nystatin showed the narrowest range of minimum inhibitory concentration (MIC) (0.25-16 μg/ml) against all Candida strains, whereas fluconazole (0.063-64 μg/ml) demonstrated the widest MIC range. In the current study, C. lusitaniae, as the second most common causative agent of VVC, was susceptible to all antifungal agents. Furthermore, 61.1% of C. lusitaniae isolates were inhibited at a concentration of ≤ 2 μg/ml, while38.9% (n=7)of them exhibited fluconazole MICs above the epidemiologic cutoff values (ECV). Candida species showed the highest overall resistance against fluconazole (61.3%), followed by itraconazole (45.2%) and caspofungin (23.7%). All of C. albicans strains were resistant to itraconazole with a MIC value of ≥ 1 μg/ml; in addition, 87.5% of them were resistant to fluconazole. Moreover, 100% and 87.5% of C. glabrata strains were resistant to caspofungin and fluconazole, respectively.Conclusion: As the findings revealed, the majority of VVC cases were caused by non-albicans Candida species which were often more resistant to antifungal agents. Candida lusitaniae generally had fluconazole MICs above the ECV. Given the propensity of C. lusitaniae to develop resistance under drug pressure, antifungals should be administered with caution. The emergence of these species justify the epidemiological surveillance surveys to watch out the distribution of yeast species.

ObjectivesTo assess the magnitude of internalised stigma and associated factors among patients with bipolar disorder attending the outpatient department of Amanuel Mental Specialized Hospital, Addis Ababa, Ethiopia.DesignInstitution-based cross-sectional study design.SettingAmanuel Mental Specialized Hospital, Addis Ababa, Ethiopia.ParticipantsWe recruited about 418 participants using systematic sampling technique for an interview during the study period.MeasurementData were collected by face-to-face interviews. Internalized Stigma of Mental Illness scale was used to measure internalised stigma. The Rosenberg Self-Esteem Scale and the Oslo-3 Social Support were instruments used to assess the associated factors. Bivariate and multivariate logistic regressions were performed to identify factors associated with the outcome variable. ORs with 95% CI were computed to determine the level of significance.ResultsThe magnitude of internalised stigma was 24.9% (95% CI: 21.2% to 28.9%). In the multivariate analysis, unemployed (adjusted OR (AOR)=2.3, 95% CI: 1.0 to 5.0), unable to read and write (AOR=3.3, 95% CI: 1.05 to 10.7), poor social support (AOR=5.3, 95% CI: 1.9 to 15.0), ≥4 previous hospitalisations due to bipolar disorder (AOR=2.6, 95% CI: 1.1 to 6.1) and low self-esteem (AOR=2.4, 95% CI: 1.1 to 5.1) had a significant association with internalised stigma.ConclusionsOne in four patients with bipolar disorder reported high internalised stigma. Unemployment, low educational status, low self-esteem, poor social support and being hospitalised more than three times before were significantly associated with internalised stigma. Thus, a stigma-reduction programme focusing on self-esteem improvement and psychological health of patients to increase their stigma resistance to counteracting effects of internalised stigma is essential.

Necrotizing enterocolitis (NEC) remains to be the most critical and frequent gastrointestinal disorder understood in neonatal intensive care units (NICU). The presented study was intended to assess the prevalence of NEC and associated factors among enteral Fed preterm and low birth weight neonates. Institution based retrospective cross-sectional study was conducted on 350 enteral Fed preterm and low birth weight neonates who were admitted at selected public hospitals of Addis Ababa from March 25/2020 to May 10/2020. The data were collected through neonates’ medical record chart review. A total of 350 participants were enrolled in to the study with the response rate of 99.43%. One hundred eighty-four (52.6%) of them were male. The majority 123 (35.1%) of them were (32 + 1 to 34) weeks gestational age. The prevalence of NEC was (25.4%) (n = 89, [95% CI; 21.1, 30.0]). Being ≤28 weeks gestational age (AOR = 3.94, 95% CI [2.67, 9.97]), being (28 + 1 to 32 weeks) gestational age (AOR = 3.65, 95% CI [2.21, 8.31]), birth weight of 1000 to 1499 g (AOR = 2.29, 95% CI [1.22, 4.33]), APGAR score ≤3 (AOR = 2.34, 95% CI [1.32, 4.16]), prolonged labor (AOR = 2.21, 95% CI [1.35, 6.38]), maternal chronic disease particularly hypertension (AOR = 3.2, 95% CI [1.70, 5.90]), chorioamnionitis (AOR = 4.8, 95% CI [3.9, 13]), failure to breath/resuscitated (AOR = 2.1, 95% CI [1.7, 4.4]), CPAP ventilation (AOR = 3.7, 95% CI [1.50, 12.70]), mixed milk (AOR = 3.58, 95% CI [2.16, 9.32]) were factors significantly associated with NEC. Finally, the prevalence of NEC in the study area was high. So that, initiating the programs that could minimize this problem is required to avoid the substantial morbidity and mortality associated with NEC.
