Abstract
In recent decades, the epidemiology of invasive candidiasis (IC) has progressively changed worldwide. This notably includes emergence of several Candida species. Although some surveillance programs provided global trends in IC epidemiology, data from countries from the Middle East and North Africa (MENA) remain scarce. In this manuscript, we reviewed the existing available data on the epidemiology of Candida species associated with IC, particularly candidemia, in MENA region regarding species distribution. As witnessed worldwide, an evident shift of Candidaalbicans towards non-albicansCandida (NAC) has been observed in the MENA region. The worrying emergence of multi-drug resistant Candida species in MENA calls for a better understanding of their epidemiology. This represents an essential prerequisite for the implementation of effective infection control strategies and surveillance systems to prevent IC among high-risk patients.

Abstract
Pneumocystis colonization may play a role in transmission and local inflammatory response. It was explored in patients with respiratory diseases in North Lebanon. Overall prevalence reached only 5.2% (95% CI 2.13–10.47) but it was higher (17.3%) in the subpopulation of patients with chronic obstructive pulmonary disease (COPD). COPD was the only factor associated with a significantly increased risk of colonization. mtLSU genotyping revealed predominance of genotype 2, identified in five patients (71.4%), including one patient who had co-infection with genotype 3. These first data in North Lebanon confirm Pneumocystis circulation among patients with respiratory diseases and the potential for transmission to immunocompromised patients.

Abstract
Tetanus is a serious illness that kills about one million people a year globally. This study aimed to i) evaluate immunity against tetanus (by antibodies titres in blood) among health staff and students at the Public Health Faculty, Lebanese University, ii) explore the determinants of the anti-tetanus immunity by a questionnaire and iii) estimate anti-tetanic serum use in the emergency departments of two hospitals (1 private, 1 public) in Tripoli. Most of the participants (76.6%) had anti-tetanus antibody titres ≥ 0.1 UI/mL. There was no association between immune status and gender (P = 0.614) but more participants ≤ 25 years were immunized than those > 25 years (P < 0.001) and more students were immunized than employees (P = 0.032). There was an inverse association between anti-tetanus immunity and having visited a physician in the past year (P = 0.009). In 2011, 1037 people received anti-tetanus immunoglobulins at the hospitals, 73% at the private hospital. Vaccination campaigns targetting adults > 25 years may be warranted to assure good anti-tetanus protection and avoid administration of anti-tetanus immunoglobulins in emergency departments.

Abstract
OBJECTIVES The aim of our study was to confirm the identification of 113 meticillin-resistant Staphylococcus aureus (MRSA) strains by pyrosequencing, to determine the susceptibility of these clinical isolates to various classes of antibiotics, to determine the minimum inhibitory concentration (MIC) to glycopeptides, and to detect mecA and luk-PV genes. METHODOLOGY The Staphylococcus species was identified by pyrosequencing of the variable region (V3) of the 16SrRNA. The susceptibility of these 113 strains of MRSA to antibiotics was determined by the disk diffusion method on Mueller-Hinton agar. The MIC of glycopeptides was determined by using the dilution method on solid media. mecA gene and luk-PV gene were detected by PCR. RESULTS The disk diffusion method proved full susceptibility to vancomycin, teicoplanin, and linezolid; whereas MIC (dilution method) indicated that 5/113 strains were resistant to teicoplanin, giving a probability of having heterogeneous glycopeptide intermediate S. aureus (hGISA) strains. The mecA gene was detected in all MRSA strains ruling out the probability of having new variants of this gene in the tested strains. The luk-PV gene was detected in 28 out of 113 MRSA strains (24.8%). CONCLUSION The originality of this study was the detection of hGISA strains knowing that they were susceptible to glycopeptides according to the diffusion method. Thus it is necessary to check the level of susceptibility of MRSA clinical isolates to glycopeptides for immunodeficient patients, by determining the MIC.

Abstract
The aim of this study was to determine the capsular typing and type b prevalence of clinical Haemophilus influenzae strains in north Lebanon in both invasive and non-invasive disease and to determine the susceptibility pattern and the mechanism of resistance to β-lactams [β-lactamase-producing strains and β-lactamase-negative ampicillin resistant (BLNAR) strains]. Fifty-two strains of clinical H. influenzae were isolated from 312 clinical specimens; the resistance pattern to β-lactams of these strains was determined by using the disc diffusion and E-test methods followed by molecular methods such as PCR of blaTEM et blaROB genes. Nine (17.4%) of the 52 strains were resistant to ampicillin; all of them produced type TEM-1 β-lactamase. In the susceptible strains 15.3% were not fully susceptible to β-lactams or considered low BLNAR strains. Slide agglutination serotyping showed that 30.7% of the strains were type b.

Abstract
OBJECTIVES We investigated the prevalence and the risk factors of nasal carriage of Staphylococcus aureus carrying Panton-Valentine leukocidin genes [Sa PVL(+)] in pupils. STUDY POPULATION AND METHODS Two hundred and fifty-seven pupils were screened by nasal swabbing. The detection of 16S rRNA, mecA and luk-PV genes was performed by PCR and the risk factors were assessed with the statistical analysis of a questionnaire. RESULTS Thirty-one percent of pupils were colonized, with 16.4% of isolates carrying the luk-PV gene and 8.8% the mecA gene. Children aged 7years or more and living in a boarding school were the factors promoting nasal carriage 60% of children who presented with an abscess in the previous year were carriers of luk-PV gene Sa. CONCLUSION The study revealed a high prevalence of luk-PV gene among methicillin-susceptible strains and a statistically significant correlation between the presence of this gene and presenting with an abscess.

Abstract
Campylobacter species are a major cause of human diarrhoeal disease worldwide. In Lebanon, the true prevalence of Campylobacter infections and the species distribution in childhood diarrhoea are not known. This study in 2010 investigated the prevalence of Campylobacter species and its possible etiologic role in childhood diarrhoea in north Lebanon. A total of 90 stool samples from children (aged 1 month to 10 years) presenting with diarrhoea were collected from 5 hospitals. A polymerase chain reaction technique (PCR) was used for each sample forthe amplification of all Campylobacter species followed by 5 PCR reactions for the amplification of C. jejuni, C. hyointestinalis, C. coli, C. fetus and C. upsaliensis. Of the 90 samples, 10 were positive for Campylobacterspecies (11.1%):1 for C.coli, 1 for C. jejuni, 2 for both C. jejuni and C. coli, and 6 could not be identified to the species level with the available primers. Campylobacter species is frequently associated with childhood diarrhoea in north Lebanon but Campylobacter infection may be significantly underdiagnosed because the search for Campylobacter is not part of the routine stool culture.

Abstract
Between 1 December 2007 and 31 May 2008, we analysed 120 nasopharyngeal swabs for the presence respiratory syncytial virus (RSV) infection in 120 children aged 15 days to 6 years, hospitalized in 2 hospitals in North Lebanon. Of the 120 samples, 32 were positive (26.7%) for RSV. There was a peak in January which progressively disappeared from February to May. Being positive for RSV was significantly associated with the presence of rhinorrhoea and dyspnoea as clinical symptoms and the absence of pneumonia signs on chest X-ray and the diagnosis of bronchitises or bronchiolitis. Testing for RSV is important in cases of respiratory infections in children as it may limit unnecessary prescription of antibiotics.

We investigated the prevalence of bacterial and parasitic infections among workers in a pastry factory in North Lebanon in 2004. We found 39% of the workers (n = 196) had nasal carriage of Staphylococcus aureus. Resistance of S. aureus isolates was 98.7% to penicillin G, 24.7% to fusidic acid, 14.3% to pefloxacine and tetracycline, 11.7% to erythromycin, 6.5% to oxacillin and amoxicillin-clavulanate. Salmonella typhi was not found in any of the workers. Prevalence of intestinal parasites was 57.8% (n = 308). Amoebae comprised 72.5% (68.3% Entamoeba coli, 15.5% E. histolytica), followed by flagellates (18.0 %) (37.5% Dientamoeba fragilis, 31.3% Giardia lamblia) and nematodes (7.8%) (only Ascaris lumbricoides). The tuberculin test was positive in 16.3% of the workers (n = 301).

Abstract
OBJECTIVE The authors had for aim to determine the prevalence of bacteremia diagnosed in an emergency department (ED), the susceptibility of microorganisms to antibiotics, and the impact on therapeutic management. DESIGN A retrospective analysis was made on patient features, microbiological ecology, susceptibility to antibiotics, and modalities of antimicrobial therapy in the Georges Pompidou European hospital ED of Hôpital, between 1 November 2001 and 30 June 2002. RESULTS One thousand four hundred and thirty two blood cultures were obtained from 1069 patients. The rate of positive cultures was 12%, but only 8.7% (n = 125) were proved as true bacteremia. The most frequently identified organisms were: Enterobacteriaceae (n = 63, 39.4%) with a predominance of Escherichia coli (n = 48, 30%), and Streptococcus pneumoniae (n = 16, 10%). Forty two cases of pyelonephritis and 34 of prostatitis both due to E. coli were diagnosed. 76.5% of these were resistant to amoxicillin, 64.7% to amoxicillin-clavulanic acid, 11.8% to ciprofloxacin, and 44% to cotrimoxazole. No resistance to third generation cephalosporin was detected in E. coli isolates. Fourteen S. pneumoniae pneumonia cases were diagnosed. 57.1% of isolates presented with a decreased susceptibility to penicillin (CMI > 0.1 mg/l). Susceptibility to amoxicillin and cefotaxim was 85.7% and 92.9% respectively. Blood culture was the only exam available for bacterial diagnosis in 51.5% of true bacteremia. 1.6% of blood cultures from ED samples had an impact on therapeutic management. CONCLUSIONS Blood culture is a relevant exam for the diagnosis of infection in patients admitted to the ED.

Abstract
Two cases of invasive aspergillosis (IA) in immunocompetent patients with a fulminant fatal outcome are reported. Both patients were elderly and had a history of chronic lung disease treated with prolonged inhaled corticosteroids and a short course of systemic corticosteroids. They presented with dyspnea and fever, their respiratory function deteriorated rapidly, and they died 7 days after admission. Aspergillus fumigatus was cultured from respiratory samples. IA was confirmed in one case by necropsy that showed diffuse bilateral necrotizing pneumonitis and myocarditis. In the other case, IA diagnosis was established by thoracic CT scan plus detection of Aspergillus antigen in two blood samples. These two cases demonstrate that short-term corticosteroid therapy in immunocompetent patients with underlying chronic lung conditions is a risk factor for IA, and that its evolution can be fulminant.
