Wound suppuration is the formation and accumulation of pus in the soft tissue of the wound. As a rule, the natural inflammatory reaction disappears within three to five days and later the wound heals without any character. During this time, in some cases the inflammatory reaction in the wound exceeds the limits of the physiological norm due to the external supply of bacterial germs, which leads to the formation of pus, exaggeratedly prolonging the healing process and in turn leading to serious consequences. This study aims to identify the bacteria involved in these suppurations, to study their antibiotic resistance profiles and to review the role of the nurses taking care of these patients. The study was conducted at the Menontin zone hospital from May 15 to June 21, 2013. Fifty-one patients of all ages and sexes with surgical and traumatic discharge wounds were sampled and 30 hand samples were taken from the nurses' hands before and after dressing. From the results obtained, 76 bacteria were identified, including 35 cocci and 41 bacilli. 29% of the bacteria found were Pseudomonas aeruginosa, 28% Staphylococcus aureus, 14% Escherichia coli and others. Hand samples of 10 bacteria were isolated including 4 Pseudomonas aeruginosa, 3Staphylococcus DNase-negative 2 Klebsiella spp and 1 Staphylococcus aureus. The strains isolated were particularly resistant to the antibiotics tested more specifically to β-lactam, Gentamycin Erythromycin and Colistin. The majority of strains have good sensitivity to ciprofloxacin and Fosfomycin. In view of these results, it is necessary to draw the attention of patients and nurses to the reality of the existence of these bacteria, the adequate intake of antibiotics preferably after an antibiotic test, hand washing and the use of appropriate sterile materials before and after any dressing.

Objective To examine gram-negative exit-site infection and peritonitis rates before and after the implementation of Staphylococcus aureus prophylaxis in peritoneal dialysis (PD) patients. Design Prospective data collection with periodic implementation of protocols to decrease infection rates in two PD programs. Patients 663 incident patients on PD. Interventions Implementation of S. aureus prophylaxis, beginning in 1990. Main Outcome Measures Rates of S. aureus, gram-negative, and Pseudomonas aeruginosa exit-site infections and peritonitis. Results Staphylococcus aureus exit-site infection and peritonitis rates fluctuated without significant trends during the first decade (without prophylaxis), then began to decline during the 1990s subsequent to implementation of prophylaxis, reaching levels of 0.02/year at risk and zero in the year 2000. Gram-negative infections fell toward the end of the 1980s, due probably to the implementation of better connectology. However, there have been no significant changes for the past 6 years. There was little change in P. aeruginosa infections over the entire time period. Pseudomonas aeruginosa is now the most common cause of catheter infection and catheter-related peritonitis. Conclusions Prophylaxis against S. aureus is highly effective in reducing the rate of S. aureus infections but has no effect on gram-negative infections. Pseudomonas aeruginosa is now the most serious cause of catheter-related peritonitis.

Abstract: Background The major cause of disease and even human death are bacteria. Disinfectant is widely used in various ways as an effective agent to kill or eliminate bacteria, especially in the microbial laboratory. The most commonly used disinfectants in the laboratory are ethanol, bleach, and hand soap. This study assessed the effect of the common cleaning agents against bacteria. Methodology It was an experimental study on disinfectant efficacy of ethanol, bleach, and antibacterial handwashing soap on surface disinfection. Sampling was carried out between April and June of 2017. The samples were collected from our lady of Consolata kisubi hospital which is located on Nkima Road- Kisubi, Wakiso, Uganda. The samples collected were obtained from the hospital surfaces like door handles, beds, random floors, toilets, and work surfaces before and after cleaning. Results 64 samples were collected from 32 sites. The selected nosocomial organism in the study included E.coli, Staphylococcus aureus, and Pseudomonas aeruginosa. Among the selected disinfectants, ethanol was the most effective against the available selected nosocomial organisms. Conclusion Bacteria is present on so many surfaces of the hospital, and the selection of appropriate cleaning agents is vital to achieve maximum cleaning. Bleach and liquid soap should not be used in combination if cleaning different surfaces in the hospital due to the effects of the inorganic compounds that might be present in the liquid soap that inactivates active ingredients used present in the Bleach. Recommendation The hospital should come up with a minimum inhibitory concentration of the disinfectants that is effective to be used. The support staff in charge of cleaning should be trained on the right way of cleaning and disinfecting.

Introdução: Pneumonia hospitalar é a mais fatal das infecções hospitalares, com taxas de mortalidade de 30 a 60%. Estima-se que 15% de todas as mortes associadas à hospitalização estejam diretamente relacionadas a pneumonias hospitalares. O SENTRY é um estudo de vigilância de resistência a antimicrobianos envolvendo centros médicos em todo o mundo. Objetivo: Avaliar a sensibilidade a antimicrobianos de bactérias isoladas no trato respiratório baixo de pacientes com pneumonia internados em hospitais brasileiros. Material e métodos: Foram avaliadas 525 amostras bacterianas de 11 hospitais brasileiros, como parte do programa SENTRY. Os isolados foram testados por microdiluição em caldo contra um grande número de antimicrobianos. Resultados: As cinco espécies mais freqüentes foram (n/%): Pseudomonas aeruginosa (158/30,1%), Staphylococcus aureus (103/19,6%), Acinetobacter spp. (68/13,0%), Klebsiella spp. (50/9,5%), e Enterobacter spp. (44/8,4%). Essas cinco espécies representam mais de 80% de toda a amostragem. A P. aeruginosa apresentou altas taxas de resistência à maioria dos antimicrobianos testados. As maiores taxas de sensibilidade foram apresentadas por piperacilina/tazobactam (71,5%) e meropenem (69,0%). Os compostos com maior atividade in vitro contra Acinetobacter spp. foram imipenem e meropenem (80,9% de sensibilidade) seguido pela tetraciclina (63,2%). A sensibilidade das amostras de Klebsiella spp. foi muito baixa. MICs > ou = 2mig/mL para ceftriaxona ou ceftazidima, indicando produção de ESBL, foram encontrados em 36,0% das amostras. Os antimicrobianos mais ativos contra Klebsiella spp. foram os carbapenens (100% de sensibilidade) e as quinolonas (92,0% de sensibilidade). Ceftriaxona foi ativa contra somente 56,8% das amostras de Enterobacter spp. (MIC50, 1mig/mL), enquanto a cefepima foi ativa contra 88,6% destes isolados (MIC50, <= 0,12mig/mL). A resistência à oxacilina foi detectada em 43,7% dos isolados de S. aureus. As drogas mais ativas contra essa espécie foram: vancomicina, teicoplanina, quinupristin-dalfopristin e linezolida. Conclusões: Os resultados do presente estudo mostraram alta prevalência de Acinetobacter spp. e altas taxas de resistência entre bacilos gram-negativos quando comparados com resultados de estudos norte-americanos e europeus.

Abstract The biosorption of Pb(II) ions from aqueous solution has been studied using both the intact and thermolyzed cells of Pseudomonas aeruginosa. Further, the role of the major cell wall components, namely DNA, protein, polysaccharide, and lipid, in Pb(II) binding has been assessed using an enzymatic treatment method. The Pb(II) bioremediation capability of P. aeruginosa cells has been investigated by varying the parameters of pH, time of interaction, amount of biomass, and concentration of Pb(II). The complete bioremoval of Pb(II) using intact cells has been achieved for an initial Pb(II) concentration of 12.4 mg L−1 at pH 6.2 and temperature 29 ± 1 °C. The biosorption isotherm follows Langmuirian behavior with a Gibbs free energy of −30.7 kJ mol−1, indicative of chemisorption. The biosorption kinetics is consistent with a pseudo-second-order model. The possible Pb(II) binding mechanisms of P. aeruginosa cells are discussed based on characterization using zeta potential measurements, Fourier transform infra-red spectroscopy, and energy dispersive X-ray spectroscopy. The results confirm that among the major cell wall components studied, polysaccharide shows the highest contribution towards Pb(II) binding, followed by DNA, lipid, and protein. Similar studies using thermolyzed cells show higher Pb(II) uptake compared to the intact cells both before and after enzymatic treatment.

Introduction: Performing dental practices in the oral environment leads to the transmission of microorganisms in saliva and blood to working surfaces and dental devices and their infection. Preventing transmission of infection through these devices is an important task of a dentist. Hence, this research was conducted to evaluate the disinfection quality of the dental faculty units of Ahvaz Jundishapur University of Medical Sciences (AJUMS) in Iran.Materials and Methods: In order to evaluate the quality of disinfection of the units, sampling was performed from all glasses spittoon surfaces of 90 units of the clinical unit of the AJUMS dental faculty before and after disinfection by personnel. Then, the bacteria were cultured in a medium and examined.Results: The mean (and standard deviation) of the total infection of units of the dental faculty was 46534.4 (583380.4) colonies per 1 ml before disinfection and 40265.6 (52131.1) colonies per 1 ml after disinfection, reflecting significant decrease in number of bacterial colonies after disinfection (P &lt;0.001). In addition, a significant decrease was seen in the number of bacterial colonies in the restoration, pediatric, orthodontic and diagnosis units (p &lt;0.05), but the difference before and after disinfection was not significant in the prosthetic, endodontic, surgical and periodontal units. In addition, the most common types of microorganisms in the whole units of the dental faculty were pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus, respectively, and after disinfection, the most common types of microorganisms were Pseudomonas aeruginosa, Staphylococcus aureus and Enterococcus, respectively.Conclusion: In general, this study showed that the disinfection method of units in dental faculty can not reduce the severity of infection of the units. Given what was stated, it is recommended that the method and the substances used to disinfect the unit to be changed.
