Abstract
OBJECTIVE The aim of the study was to identify the possible benefits of physical activity program in improving the antioxidant enzymes activity and lipid profile among smokers. PATIENTS AND METHODS Fifteen cigarette smokers (CS), 14 hookah smokers (HS), and 14 non-smokers (NS) participated in the low-intensity continuous training (LCT). Eleven CS, 12 HS, and 12 NS participated in the moderate-intensity intermittent training (MIT). The LCT groups performed a 20 to 30-minute continuous exercise at 40% of the VO2max. The MIT groups performed 6 to 10 sets of 2-minute sprint at 70% of the VO2max interspersed by a 1-min recovery period. At baseline and after 12 weeks of intervention, the antioxidant defense activity and lipid profile were assessed. RESULTS The improvement in antioxidant capacity under the effect of MIT program is statistically more significant than after LCT. The increase of glutathione peroxidase (GPx), superoxide dismutase (SOD), glutathione reductase (GR), malondialdehyde (MDA) and α-tocopherol was higher in smoker subjects participating in the MIT program compared to those participating in the LCT. In contrast, the LCT program has favorably altered lipid and lipoprotein profile of smokers and thus reduced their cardiovascular risk. CONCLUSIONS The combination of the two training methods may have major implications in both defense and prevention programs.

Abstract
Introduction. Trichosporon asahii has been recognized as an opportunistic agent having a limited sensitivity to antifungal treatment.Hypothesis/Gap Statement. Molecular mechanisms of azole resistance have been rarely reported for Trichosproron asahii. Similar to other fungi, we hypothesized that both ERG11 gene mutation and efflux pumps genes hyper-expression were implicated.Aim. The current work aimed to study the sensitivity of clinical T. asahii isolates to different antifungal agents and to explore their resistance mechanisms by molecular methods including real-time PCR and gene sequencing.Methods. The sensitivity of T. asahii isolates to fluconazole, amphotericin B and voriconazole was estimated by the Etest method. Real-time PCR was used to measure the relative expression of Pdr11, Mdr and ERG11 genes via the ACT1 housekeeping gene. Three pairs of primers were also chosen to sequence the ERG11 gene. This exploration was followed by statistical study including the receiver operating characteristic (ROC) curve analysis to identify a relationship between gene mean expression and the sensitivity of isolates.Results. In 31 clinical isolates, the resistance frequencies were 87, 16.1 and 3.2 %, respectively, for amphotericin B, fluconazole and voriconazole. Quantitative real-time PCR demonstrated that only Mdr over-expression was significantly associated with FCZ resistance confirmed by univariate statistical study and the ROC curve analysis (P <0.05). The ERG11 sequencing revealed two mutations H380G and S381A in TN325U11 (MIC FCZ=8 µg ml-1) and H437R in TN114U09 (MIC FCZ=256 µg ml-1) in highly conserved regions (close to the haem-binding domain) but their involvement in the resistance mechanism has not yet been assigned.Conclusion. T. asahii FCZ resistance mechanisms are proven to be much more complex and gene alteration sequence and/or expression can be involved. Only Mdr gene over-expression was significantly associated with FCZ resistance and no good correlation was observed between FCZ and VCZ MIC values and relative gene expression. ERG11 sequence alteration seems to play a major role in T. asahii FCZ resistance mechanism but their involvement needs further confirmation.

Abstract
Saksenaea vasiformis is a species of the order Mucorales rarely reported as a cause of human mucormycosis. We report an unusual case of S. vasiformis otitis occurring in a diabetic woman after penetration of an insect in the right ear. Direct microscopic examination of the clinical sample showed hyaline and non septate hyphae belonging to the order Mucorales. Fungal identification was performed by sequencing the ITS region of the rDNA. To our knowledge, this is the first report of S. vasiformis infection in Tunisia.

Abstract
OBJECTIVES Rhizopus arrhizus is recognized as an emergent agent of superficial and invasive mucormycosis. Despite an increasing number of these infections, the molecular epidemiology of Rhizopus species has not been well studied. MATERIALS AND METHODS In this study, 43 R. arrhizus strains (25 environmental and 18 clinical isolates) were genotyped using six novel panels of microsatellite markers. RESULTS Upon the analysis of 43 isolates, 4-8 distinct alleles were detected for each marker. The discriminatory power for the individual markers ranged from 0·522 to 0·830. The combination of all six markers yielded 33 different haplotypes with a high degree of discrimination (0·989 D value). A four-marker combination were selected as the most parsimonious panel achieving D > 0·95. One clinical isolate and one environmental isolate shared the same genotype suggesting the possible nosocomial outbreak of mucormycosis in hospitalized patients. We have noted that the strains isolated from cutaneous mucormycosis were different from the strains isolated from rhino-orbito-cerebral mucormycosis. Then, the hypothesis of particular tropism of infectious strains for a given site is not excluded. The standardized indices of association IA and rBarD were significantly different from zero (P < 0·01), suggesting a prevailing clonal reproduction. The environmental population was significantly differentiated from clinical populations (Fst = 0·2249). CONCLUSIONS Microsatellite typing method described in our study showed an excellent degree of discriminatory power. It is a promising tool for illuminating the molecular epidemiology of R. arrhizus species, including strain relatedness and transmission pathways.

Detection of virulence factors and antifungal susceptibility of human and avian Aspergillusflavus isolates. J Mycol Med 2019; 29:292-302.

Abstract
Aspergillusflavus is the second leading cause of invasive and non-invasive aspergillosis. Secretion of hydrolytic enzymes is considered as a virulence factor in this species. Our work aimed to study in vitro production of some virulence factors, to evaluate the biofilm production against human and avian A. flavus isolates and to investigate the antifungal susceptibility agents. Hydrolytic enzymes, biofilm production and molecular typing were studied for 62 human and 36 avian A. flavus isolates by specific solid media and six microsatellite markers. The susceptibility to antifungal agents was evaluated for 37 human isolates. All human and avian A. flavus isolates showed positive activities of extracellular hydrolase: phospholipase, protease and hemolysin. A positive elastase activity was seen in 64.51% of human A. flavus isolates and 86.1% of avian A. flavus isolates. All A. flavus in these two populations formed biofilms. Statistical significant difference was observed for the mean phospholipase activities (P=0.025) and biofilm quantification (P=0.0001) between human and avian A. flavus isolates. The in vitro susceptibility results showed a resistance in 83.7%, 81.08% and 16.21% of A. flavus isolates respectively to amphotericin B, itraconazole and posaconazole. No association was noted between all virulence factors and the genotypes of human and avian isolates. Our study allowed us to show that human strains have a higher production of extracellular hydrolases and biofilm then avian strains. These virulence factors appear to act synergistically to contribute to the virulence of A. flavus strains. Moreover, significant correlation between virulence patterns and antifungal susceptibility profiles was observed.

Abstract
Fungi are morphologically and phylogenetically diverse. There identification is largely based on phenotypic methods. Thus, related species, phenotypic variants and rare species may be unidentified. So, molecular methods have been introduced for identification of pathogenic molds to overcome these problems. In this study, we report the contribution of molecular tools (PCR sequencing) to identify fungal pathogens in both clinical and environmental samples. A total of 82 mold isolates were used (50 clinical samples and 32 environmental samples). PCR and direct sequencing, targeting the internal transcribed spacer (ITS) regions, were performed. We employed comparative sequence analysis to identify molds by using the GenBank database. 89% of isolates were identified by phenotypic methods. PCR- sequencing allowed the fungal identification in all cases. The concordance between molecular and morphological identification was obtained for 33 cases (40.2%). In 36 cases (43.9%), the molecular study gave the exact species identification. PCR sequencing allowed as revising mycological identification for 13 fungi strains (15.9%). The concordance of identification at species level by phenotypic method and by sequence analysis was obtained for 28% of clinical samples and for 59% of environmental samples. The phylogenetic tree for the ITS sequences showed six different clusters that are composed of isolates belonging to the same genus or species. PCR sequencing has been shown to be useful for the detection of the presence of fungal DNA in both environmental and clinical samples. It is rapid and more sensitive for the identification of medically important fungi.

Abstract
Free living amoebas (FLA) are opportunistic pathogen found in different water sources in the environment. The aim of this study was to investigate the prevalence of free living amoeba in different samples of domestic water reserves (DWR) in Sfax region from Tunisia. It was a prospective study dealing with 486 water samples collected from different DWR. After filtration through a cellulose acetate membrane samples were cultured on non-nutrient agar and the FLA were detected and strained with Giesma, Trichrome and red nuclear stain for morphological and morphotypic studies. FLA were found in 62% of samples. The Acanthopodial morphotype was detected in 43%, Polytactic (38%), Monotactic (28%), Fan-shaped (17%), Rugose (11%), Dactilopodial (10%) and Eruptive (9%). These results demonstrate that domestic water reserves are a significant source of the FLA and maintenance of DWR is recommended.

Abstract
UNLABELLED Fungal keratitis is responsible for a significant burden of blinding disease in the developing world. OBJECTIVE The aim of this study was to determine the etiological agents, predisposing factors and therapy of keratomycosis in our region. METHODS Retrospective study of 60 patients with clinically and cultured confirmed fungi keratitis, who were attended at department of mycology in Sfax (1995 to 2012). RESULTS The mean age of patients was 47.2 years (sex ratio: 1.58). At least, one presumed predisposing factor was identified in 83.3% of cases. Corneal traumatism was established as the most common predisposing factor (61.6%) with vegetative matter (42.4%). Patients had corneal ulcer in 40% or abscess in 47.6%. All cases were positive on direct microscopy and 93% of cultures were positive. Filamentous fungi form the major etiologic agents (83%): Fusarium species (49% with F. solani [66%]), Aspergillus sp. (22%), Alternaria (5%), Scedosporium sp. (2%); and non-identified mold in (5%). Yeast were identified in 17% of cases. Topical agents were used in 97% of cases: ketoconazole 2%, amphotericin B (0.5%). Fluconazole per os was administrated for 11% of cases, itraconazole (2 cases) and voriconazole (one case). Keratoplasty was indicated for 27% of cases. The outcome was favorable in 16% of patients. Among the patients, 71% had persistent corneal deposit sequelae. Four patients lost the eyeball. CONCLUSION Corneal traumatism was the principal risk factor for fungal keratitis in young and middle-aged farmers. Fusarium solani is the predominant cause in Sfax. Early diagnosis, coupled with appropriate treatment, is crucial for increasing the chance of complete recovery.

Abstract
Abstract
The present work describes the synthesis of new perfluoroalkylated carbamate group-containing glycoside-based nonionic surfactants usable as co-surfactants for stabilizing injectable oxygen-carriers PFC emulsions and as potential antithrombotic agents. The key steps of the synthetic route converting F-alkyl oxoesters into new F-alkyl glycosides are: formolysis, conversion to the respective acid chloride, isocyanate formation and glycosidation. The perfluoroalkyl group is connected through a carbamate function to 6-position of the sugar ring, and the glycosidation is performed from unprotected sugar.

Abstract
Acanthamoeba keratitis (AK) is a sight-threatening infection. We report five cases of AK diagnosed from 2005 to 2009 in the Laboratory of Parasitology-Mycology at Habib Bourguiba Sfax Hospital, Tunisia. All were associated with improper care of contact lenses (rinsing of contact lenses with tap water and inappropriate cleaning) and lens storage. The patients displayed different clinical presentations: corneal inflammation, corneal ulceration, and corneal abscess. The diagnosis was made after direct examination, culture, and polymerase chain reaction amplification with specific primers. The genotype classification was based on the highly variable DF3 region in the 18S rRNA gene. This is the first study characterizing Acanthamoeba genotype in Tunisia and North Africa. All Acanthamoeba isolates were associated to the T4 genotype. Three different DF3 sequence types were related to AK infections T4/10, T4/15, and T4/16.

Abstract
Abstract The frequency of toxoplasmosis depends on life-style and environment. Our objective was to study different epidemiological, clinical and biological aspects of toxoplasmosis in the Sfax area (Tunisia). This retrospective study has been performed on seria of 40,566 pregnant women in the Parasitology-Mycology Laboratory of Habib-Bourguiba Sfax hospital-Tunisia for 13 years from 1994 to 2006; 1,691 patients presenting with lymphadenopathy; 191 immunocompromised patients (78 HIV infected patients and 113 transplanted patients) and 21 patients presenting clinical signs of ocular toxoplasmosis. In pregnant women, the seroprevalence was 39.3% (15,952/40,567). Among 24,089 seronegative women, only 6,890 (28.6%) had been followed up during their pregnancy. An active toxoplasmosis possibly acquired during pregnancy was detected in 1.3% of cases. Sixteen congenital toxoplasmosis were detected. Toxoplasmosis was confirmed in 13.7% of the 169 patients with lymphadenitis. For HIV positive patients, 11.7% had cerebral toxoplasmosis. It revealed the HIV infection in four cases. Among transplant recipients, one case of active toxoplasmosis was diagnosed in a renal transplant recipient who received transplant from a seronegative donor. Twenty-one patients presenting toxoplasmic retinochoroiditis were treated by subconjonctival injections of clindamycin and systemic corticotherapy at a dose of 1 mg/kg per day. This clinical toxoplasmosis diversity explains the need for bioclinical confrontation to establish diagnosis.
