Objectives: The aim of the current study was to reveal the bacterial profile and pattern of sensitivity to antibiotics for external ocular infections for patients who attended selected ophthalmology clinics in the city of Sana’a. Methods: A cross-sectional study design was used from September 2016 to October 2017 where a total of 197 patients with infection of external eye were included in the study which included conjunctivitis, keratitis, blepharitis and Blepharoconjunctivitis. Samples were collected and transferred to the National Center of Public Laboratories (NCPHL), in Sana'a. Possible bacterial pathogens have been isolated and identified using regular laboratory techniques, and microbial sensitivity testing has been carried out using a disc diffusion method. Results: A total of 197 ocular samples were obtained for microbiological evaluation, of these 146 (74.1%) have bacterial growth. Bacteria of Gram positive accounted for 52.1% and the prevalent isolation was S. aureus (30.1%). Gram negative bacteria made up 47.9% and the predominant isolation was Pseudomonas aeruginosa (26.7%). The majority of Gram-positive bacteria were sensitive to ciprofloxacin (90% - 100%), vancomycin (86% - 100%) and Gram-negative isolates sensitive for amikacin (100%) and ciprofloxacin (63% - 100%). Conclusion: These results revealed that Gram-positive bacteria were the generally common bacteria isolated from infections of external eye and were more susceptible to vancomycin and ciprofloxacin while Gram-negative isolates were more susceptible to ciprofloxacin and amikacin.  The high rate of resistance for most antibiotics in Yemen, leaves ophthalmologists with very few options of drugs to treat eye infections. Large-scale ongoing studies in the future should also be conducted in order to monitor the antimicrobial resistance of the external ocular bacterial isolates.

Objectives:  Lower respiratory infections (LRTIs) are the leading reason of death infectious diseases in the world and the fifth leading cause of death in general. The study aimed to identify the general characteristics of LRTI, the causative bacteria and the results of sensitivity to antibiotics. Subjects and methods:  A multicentre prospective study was performed at 3 University hospitals. The study included 555 clinical diagnostic cases as LRTI cases, 328 male and 227 female, aged 3 to 69 years. Clinical and demographic data were collected in the standard questionnaire, and samples included sputum or bronchial lavage (BAL) staining and culture. Samples were cultured in 3 different bacterial media, blood agar and LJ slope, chocolate agar with Co2; cultures were then examined for possible bacterial pathogens of LRTI. Possible bacterial pathogens were isolated and identified by standard laboratory techniques, and microbial sensitivity testing was carried out by disc diffusion method. Results:  LRTI was recorded among all age groups and with less frequency in children less than 16 years of age. A large number of LRTI (36.2%) was not diagnosed, most in CAP (52.4%), followed by HAP (33.9%) while unidentified cases were lower in AECOPD (22.8%). CAP isolates are K. pneumoniae (26.2%), S. pyogens (12.3%), and S. pneumoniae (9%); in HAP are MSSA (24%), E. Coli (12.9%), MRAS (11.1%), K. pneumoniae (10.5%) and P. aeruginosa (7%); and in AECOPD are M. catarrhalis (47.2%), K. pneumoniae (17.2%), H. influnzae (10.7%) and P. aeruginosa (2%). In Gram-positive bacteria, high resistance to ampicillin/sulbactam (100%) and amoxicillin/clavulanate (100%) was recorded, while moderate resistance to amikacin, vancomycin, cefepime and moxifloxacin was recorded. In Gram-negative bacteria, a high resistance to 3rd g Cephalosporin’s  (68.5%) was recorded, while a moderate sensitivity to the other antibiotics tested was recorded. Conclusion:  There is a high rate of undiagnosed LRTI in Yemen and this highlights the need for health authorities to develop strategies to diagnose most of the causes of LRTI, including Mycoplasma, Chlamydia, and viral causes. No antibiotics are completely effective in treating LRTI in our area and antibiotic sensitivity should be performed in all cases.

magnesium oxide nanoparticles (MgO NPs) were prepared by simple wet chemical method using different calcination temperatures. The prepared NPs were characterized by Electrostatic Discharge (ESD), Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD). It demonstrates sharp intensive peak with the increase of crystallinty and increase of the size with varying morphologies with respect to increase of calcination temperature. Antibacterial studies were done on gram negative bacteria (E.coli) and gram positive bacteria (S.aureus) by agar disc diffusion method. The zones of inhibitions were found larger for gram positive bacteria than gram negative bacteria, this mean, antibacterial MgO NPs activity more active on gram positive bacteria than gram negative bacteria because of the structural differences. It was found that antibacterial activity of MgO NPs was found it has directly proportional with their concentration.

Abstract Background Conventional antimicrobial susceptibility testing (AST) of microorganisms from positive blood cultures (PBC) can take ≥ 2 days. In order to improve the turnaround time for AST on a PBC, CLSI and EUCAST have made efforts to standardize procedures for disk diffusion (DD) direct from a PBC. Qvella Corporation (Richmond Hill, ON, Canada) has recently developed FAST-Prep, an automated centrifugal sample preparation system that rapidly delivers a Liquid Colony consisting of a purified, concentrated, viable cell suspension directly from a PBC. This study was performed to investigate the feasibility of DD AST off of a PBC using a FAST-Prep Liquid Colony. Methods Contrived PBC samples were prepared by spiking 6 species of Gram-positive and 4 species of Gram-negative bacteria (3-5 strains per species) into FA® Plus bottles and incubating in the BACT/ALERT® VIRTUO® System (bioMerieux, Durham, NC). After positivity, 3 mL of PBC was added to the FAST-Prep cartridge. After 20 minutes of processing in the FAST-Prep instrument, the Liquid Colony was removed from the cartridge and a 0.5 McFarland sample was prepared for DD AST. In parallel, the DD AST from a PBC was performed using 4 drops of PBC (CLSI direct method). Both methods were compared to conventional colony-based DD AST. After 16-18 hours of incubation zone diameters and S/I/R interpretations were determined. Categorical agreement (CA) and errors for both DD AST methods were calculated. In addition, colony plate counting was performed on 0.5 McFarland suspensions of Liquid Colony and the plate colony to determine biomass recovery and sample purity. Results CA for a FAST-Prep DD AST for Gram-positive and Gram-negative bacteria was 95.6% and 98.6%, respectively, compared to CA for CLSI DD AST of 77.2% and 81.9%, respectively. Biomass in the Liquid Colony was 7.2x108 and 1.2x109 CFU for Gram-positive and Gram-negative bacteria, respectively. Cell concentration in the 0.5 McFarland suspension of the Liquid Colony was 3.7x107 and 5.9x107 CFU/mL for Gram-positive and Gram-negative bacteria, respectively, which was similar to the concentration for the reference colony suspension. Conclusion The results support the potential role of FAST-Prep in providing a Liquid Colony for use in rapid AST. Disclosures Susan M.

Methanolic Extracts

Pycnarrhena cauliflora (Miers.) Diels., local name sengkubak, is one of indigenous plants from West Kalimantan that has been used as natural flavor. Pycnorrhena cauliflora is one of species of Menispermaceae family which is rich in bisbenzylisoquinoline alkaloids. This alkaloids are known to have various biological activities including antiprotozoal, antiplasmodial, antifungal and antibacterial activities. This study aimed to investigate antimicrobial activity of  the P. cauliflora (Miers.) Diels. methanolic extracts against gram-positive and gram-negative bacteria. The methanolic extract of P. cauliflora (Miers.) Diels., root, leaf and stem were prepared by maceration. The disk-diffusion method was then used to determine the antimicrobial activity of the extracts against Streptococcus pyogenes, S. mutants, Staphylococcus aureus, S. epidermidis, Salmonella typhi, Shigella flexneri, Pseudomonas aeruginosa and Escherichia coli after 18-24 h incubation at 37 oC. Amoxicillin was used as positive control for gram-positive bacteria and ciprofloxacin was used as gram-negative bacteria. The inhibition zones were then measured in mm. Analysis were conducted in duplicates. The results showed in general the methanolic extracts of P. cauliflora (Miers.) Diels. root (inhibition zone diameter= 10-23 mm) were more active than that leaf (0-15 mm) and stem (0-17 mm) extracts against gram-positive bacteria. The zone inhibition diameter of amoxicillin as positive control was 8-42 mm. In addition, the methanolic extracts of P. cauliflora (Miers.) Diels. root (12-17 mm) were also more active than that leaf (0-12 mm) and stem (0-12 mm) extracts against gram-negative bacteria. The zone inhibition diameter of ciprofloxacin as positive control was 33-36 mm. In conclusion, the methanolic extract of P. caulifloria (Miers.) Diels. root is the most extract active against both gram-positive and gram-negative bacteria. Further study will be focused to isolate active compounds in the methanolic extract of the root.

Wild Berries

Wild berry is an excellent source of phytonutrients and/or bioactive compounds associated with significant therapeutic properties, so that they have been utilized in folk medicine and traditional nutrition throughout centuries. Multiple health-promoting effects, such as anti-inflammatory, anti-diabetic, anti-heart and coronary disease properties were attributed to such wild berries. It has also been proved that berries could feature antimicrobial effects that could be of a great importance for the prevention of food-feed poisoning and fighting back antibiotic resistance. In this study, we investigated the antimicrobial properties of lingonberry (Vaccinium vitis-idaea), raspberry (Rubus idaeus) and blackberry (Rubus fruticosus) crude and ethanolic extracts prepared from fruits obtained from the spontaneous flora of Eastern Carpathian Mountains situated in Transylvania. The antimicrobial effect of crude and alcoholic extracts were assessed on four Gram-negative, five Gram-positive bacteria and one yeast species using the agar diffusion method. The studied bacteria can cause food or feed spoilage and foodborne diseases. Our results indicate the significant inhibitory effect of lingonberry extracts in the case of Gram-negative bacteria like Proteus vulgaris and Salmonella Hartford, while among Gram-positive bacteria the strongest inhibitory effect was observed for Bacillus species like B. cereus, B. subtilis, B. mojavensis and Micrococcus luteus. The raspberry and blackberry extracts featured milder inhibitory effects in the case of the studied bacteria species. Furthermore, we have studied the crude or ethanolic extract combinations associated antimicrobial effects synergistic/additive or antagonistic properties. Interestingly, the triple and double ethanolic extract mixes had stronger antimicrobial properties, whereas the crude extract mixes showed relatively reduced effects, if any. Our results indicate that the antimicrobial activity of studied fruit extracts obtained from wild berries can vary upon the applied extraction method and their combination formulae, so that all these considerations must be taken into account when such fruit extracts are considered for foodstuff development.

Vaginal Swabs

Normal vaginal flora contains a wide range of microorganisms. Hydrogen peroxideproduced by Lactobacillus strains plays a vital role in maintaining the microenvironment of thevagina and in the inhibition of overgrowth of potentially pathogenic bacteria. Bacterial vaginosisBV is the main reason of vaginal discharge. Many gram positive and gram negative rods i.e.E.coli, Klebsiella, Proteus, Acinetobacter and Pseudomonas spp. are major contributors inbacterial vaginosis. Aim: The present study was conducted to elucidate the frequency of variousgram-negative rods in high vaginal swabs and sensitivity pattern of bacteria to antibiotics thatare currently used. Study Design: Cross sectional study. Setting: Department of Obstetricsand Gynecology of Benazir Bhutto Hospital Rawalpindi, a tertiary health care center for thepeople of Rawalpindi. Period: January 2015 to May 2016. Material and Methods: A total of220 High vaginal swabs (HVS) were collected both from indoor and outdoor patients presentingwith symptoms of vaginal discharge aged between 20 to 65 years. Swabs were inoculated onblood, Chocolate and MacConkey’s agar. After overnight incubation plates were examined forgrowth, colonial morphology, final confirmation was done on the basis of biochemical testingand API 20-E system (BioMerieux, France) up to species level. Antibiotic sensitivity testing wasdone by (modified Kirby-Bauer’s) disc diffusion method using amikacin, ampicillin, amoxicillinclavulanic acid, imipenem, ceftazidime, tigecycline, ciprofloxacin, sulzone and cefixime. Afterovernight incubation plates were examined to read the susceptibility zone. Results: Out of 220HVS samples, 100 samples showed bacterial growth and confirmed as Gram negative bacilli.Age wise distribution of infection showed highest rates b/w age 20-30 was 36% followed by 31-40 (23%), 41-50 (25%) and 11% above 50 years of age. Bacteria isolated from HVS were E.coli(53%), Klebsiella (22%), Pseudomonas (12%), citrobacter (6%), Proteus (5%) and Acinetobacter(2%) respectively. Highly sensitive antibiotics against bacteria were imipenem (96%), sulzone(90%) and Ciprofloxacin (88%), whereas least affective antibiotics against gram negative rodswere penicillins (ampicillin, amoxicillin-clavulanic acid), amikacin due to indiscriminate use ofantibiotics. Conclusion: High prevalence of gynecological infections demands that the patientswho have vaginosis must be investigated regularly and carefully through culture and identificationof causative bacteria. Emergence of antibiotic resistance must be controlled in order to avoidimproper use, frequent abuse, insufficient dosages, trouble-free availability of antibiotics andtreatment schedule must be designed subsequent to proper laboratory investigations.

BACKGROUND: Urinary tract infections (UTIs) is a worldwide problem of all age groups and gender. Emerging resistance to antibiotics making difficult in the choice of treatment and management of UTI cases. This study sought to determine the gender wise prevalence of common uropathogens from UTI patients and the resistance profile of uropathogens against commonly used antibiotics.METHOD: This cross sectional study was conducted in Al Buraimi Hospital, Sultanate of Oman. The data of UTI patients visited hospital was analyzed for the isolation of uropathogens from positive urine culture and antimicrobial sensitivity test was performed by disc diffusion method. Descriptive statistics was used to analyze the data using SPSS 21.0 and Microsoft Excel.RESULT: Total 4,480 urine samples were analyzed for isolation of uropathogens and significant bacteriuria were found in total 846 (19%) samples. Overall 728 (86%) Gram-negative and 118 (14%) Gram positive uropathogens were isolated from total (846) positive urine samples and the highest prevalence of isolates was observed in females 542(74%) than males 186(26%). E.coli was found the highest prevalent (50.3%) uropathogens followed by Klebsiella species (13.9%), Pseudomonas (6.3%), A.baumannii (4%), E.Cloacae (2.2%), Proteus species (1.4%), Citrobacter species (1.2%), M. morgani (0.3%) and Serratia species (0.1%). The highest (34.3%) antibiotic resistance was noticed in E.coli against Nalidixic Acid, however, susceptiblity was found against Ceftriaxone, Ceftazidime, Ciprofloxacin and Nitrofurantoin among female and males.CONCLUSION: Overall, β- lactam antibiotics, Cephalosporins, Fluroquiolones, Macrobids would be the first line of drugs and the most effective for the empirical treatment of Gram-negative and Gram-positive uropathogens; however Aminoglycosides, Carbapenems and Polymyxin could be used for the treatment of UTI infections as the second choice.

Patients diagnosed with multiple myeloma are more susceptible to infections which are the major causes of morbidity and mortality associated to this disease. The main infectious agents involved are Gram-positive bacteria. However, after chemotherapy an increase in the incidence of Gram-negative strains is observed. These bacteria are also responsible for most cases of urinary tract infections. Here is reported a rare case in a 73-year-old man with multiple myeloma who developed endocarditis due to pseudomonas.
