Kingella kingae is a Gram-negative coccobacilli and it is a member of the HACEK (Haemophilus species, Aggregatibacter actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae) group. HACEK organisms are typically oropharyngeal commensals and have long been recognized as a cause of infective endocarditis in children and adults. K. kingae in difficult to recover from cultured pharyngeal samples due to its slow growth and the high presence of resident bacterial flora. However, the organism can be better detected using PCR tests. Based on our literature in PubMed and other sources, we couldn't discover any study about K. kingae originated in an Arab country. Therefore, we prepared this review in order to draw attention of our physicians and clinical microbiologists to the importance of this neglected group of organisms in clinical medicine.

Abstract Pseudomonas aeruginosa threatens patient’s care. It is considered as the most complicated health care associated pathogen to be eliminated from infection site. The biofilm forming ability of P. aeruginosa, being a major virulence factor for most pathogenic microorganism, protects it from host immunity and contribute to antibiotic resistance of this organism. It is estimated that about 80% of infectious diseases are due to biofilm mode of growth. Biofilm forming ability of bacteria imparts antimicrobial resistance that leads to many persistent and chronic bacterial infections. The world is becoming increasingly under the threat of entering the “post-antibiotic era”, an era in which the rate of death from bacterial infections is higher than from cancer. This review focus on P. aeruginosa biofilm forming ability; definition, developmental stages, and significance. In addition, the quorum sensing and the antibiotic resistance of this pathogen is discussed. Keywords: Biofilm; bacterial adhesion; Pseudomonas aeruginosa; antimicrobial resistance; quorum sensing.
铜绿假单胞菌威胁着患者的护理。它被认为是感染部位最复杂的卫生保健相关病原体。铜绿假单胞菌(P. aeruginosa)的生物膜形成能力是大多数病原微生物的主要毒力因子,保护其免受宿主免疫,并有助于该生物的抗生素耐药性。据估计,约80%的传染病是由于生物膜的生长方式造成的。细菌的生物膜形成能力赋予抗菌素耐药性,导致许多持续性和慢性细菌感染。世界正日益面临进入"后抗生素时代"的威胁,这是一个细菌感染死亡率高于癌症死亡率的时代。本文综述了铜绿假单胞菌生物成膜能力的研究进展;定义、发展阶段和意义。此外,还讨论了该病原菌的群体感应和耐药性。关键词:生物膜;细菌粘附;铜绿假单胞菌;抗菌素耐药性;群体感应。

Antimicrobial resistance is a global public health challenge, which has accelerated by the overuse of antibiotics worldwide. Increased antimicrobial resistance is the cause of severe infections, complications, longer hospital stays and increased mortality. Steps must be taken to reverse the damage that has already been done and prevent further resistance from developing. This work will examine the context and societal situations that led to this acceptance of antibiotic overuse and misuse seen in both health care professionals and the public, the biochemical and genetic pathways that allow a microbe to develop drug resistance, the consequences that could follow if this trend of antibiotic overuse is allowed to continue and the various methods and solutions that have been suggested to prevent and reverse this problem.
抗菌素耐药性是一项全球公共卫生挑战,世界范围内抗生素的过度使用加速了这一挑战。抗菌素耐药性的增加是严重感染、并发症、住院时间延长和死亡率增加的原因。必须采取措施扭转已经造成的损害,并防止进一步的耐药性产生。这项工作将研究导致卫生保健专业人员和公众接受抗生素过度使用和滥用的背景和社会状况,允许微生物产生耐药性的生化和遗传途径,如果允许抗生素过度使用的趋势继续下去可能会产生的后果,以及已经提出的预防和扭转这一问题的各种方法和解决方案。

Background: Hepatitis B virus (HBV) reactivation can be asymptomatic or manifest as fatal fulminant hepatitis. Most international guidelines recommend screening patients prior to immunosuppressive therapy. Aims: To determine HBV screening rates and modalities in patients receiving chemotherapy at the American University of Beirut Medical Center. Methods: A retrospective cohort review of electronic health records of  adult patients who received chemotherapeutic agents, between June 2015 and June 2016. Patients clinical characteristics were documented. Adequate screening was defined as performing all: HBsAg, HBs Abs, and anti HBc Abs(total). Results: A total of 1547 patients were initially assessed. 45.6% were males with a mean age of 56. 382(30%) had hematologic malignancies, of whom 111 underwent HSCT. Of those included, 303(24%) patients were screened by at least one test for HBV and 42(3.3%) for HBsAg, anti HBc Abs and HBs Abs. Patients who were appropriately screened were significantly younger(p=0.008) and more likely to have hematologic malignancies (n=35, 83.3%, p<0.0001). Among patients with hematologic malignancies, appropriately screened patients (n=35) were younger (p=0.042) and had a history of HSCT(n=19, 54.3%, p=0.001). Conclusion: Rates of screening for HBV prior to chemotherapy at our medical center are low, and not always complete or adequate. There is an urgent need to implement a better screening policy.
背景:乙型肝炎病毒(HBV)再激活可以无症状或表现为致命的暴发性肝炎。大多数国际指南建议在免疫抑制治疗前对患者进行筛查。目的:确定贝鲁特美国大学医学中心接受化疗的患者的HBV筛查率和方式。方法:对2015年6月至2016年6月期间接受化疗药物治疗的成年患者的电子健康记录进行回顾性队列分析。记录患者的临床特征。充分的筛选被定义为执行所有:HBsAg, HBs抗体和抗HBc抗体(总数)。结果:共1547例患者被初步评估。45.6%为男性,平均年龄56岁。382例(30%)有血液系统恶性肿瘤,其中111例接受了造血干细胞移植。其中,303例(24%)患者接受了至少一项HBV筛查,42例(3.3%)患者接受了HBsAg、抗HBc抗体和HBs抗体筛查。接受适当筛查的患者明显更年轻(p=0.008),更有可能患有血液系统恶性肿瘤(n=35, 83.3%, p<0.0001)。在血液系统恶性肿瘤患者中,适当筛查的患者(n=35)年龄较小(p=0.042),有HSCT史(n=19, 54.3%, p=0.001)。结论:我院化疗前HBV筛查率较低,且不完全或不充分。我们迫切需要实施更好的筛查政策。

Background: Staphylococcus aureus including methicillin resistant S. aureus (MRSA) is one of the most effective biofilm-forming organisms, biofilm contribute in protecting the microorganism from host defenses and prevent the effective penetration of antimicrobial agents. Biofilm formation is considered as an important contributing factor for the initiation and establishment of chronic infection by S. aureus and known as a major obstacle in the treatment of S. aureus infections is their ability to develop resistance to antimicrobials. Aims : To screen clinical Staphylococcus aureus including MRSA isolates for their biofilm forming abilities and their association with antimicrobial resistance. Methods: A total of 196 clinical isolates of S. aureus were obtained from different sample sources using standard microbiological techniques from three major hospitals in Gaza strip. Biofilm formation of these isolates was determined by tissue culture plate (TCP) method and tube adherence method (TM). Antimicrobial susceptibility test was performed using the modified Kirby–Bauer disk diffusion method as per Clinical and Laboratory Standards Institute guidelines. MRSA was detected using the cefoxitin disk test. Results: Biofilm formation was observed in 174 (88.8 %) and in 145 (74.0%) isolates of S. aureus via TCP method and TM, respectively. The highest resistance percent was for penicillin (92.9%), followed by cefoxitin (80.6%) and oxacillin (67.9%), while the lowest resistance percent was for linezolid and ceftaroline (1%). Among the 196 isolates 71.4% (N=140) were classified as MDR with a MAR index (≥ 0.2). A total of 158 isolates (80.6%) were identified as MRSA distributed as 90.4%, 79.4% and 70.9% from Al-Shifa, Al-Nasser pediatrics and Al-Aqsa hospitals respectively. Large proportions (82.1%) of biofilm producers were identified as MRSA. Biofilm-producing MRSA exhibited a higher percent (90.5%) when compared with the biofilm non-producer MRSA (9.5%). Importantly, 89.2% of biofilm-producing S. aureus were multidrug resistant. Conclusions: S. aureus isolates possessed high biofilm-forming ability. Biofilm-producing strains have very high tendency to exhibit antimicrobial resistance, multidrug resistance and methicillin resistance. Regular surveillance of biofilm formation by S. aureus and their antimicrobial resistance profile may lead more success in treating S. aureus infections.   Keywords: Biofilm, MDR, MRSA, TCP, TM, Gaza strip, Palestine.
背景:包括耐甲氧西林金黄色葡萄球菌(MRSA)在内的金黄色葡萄球菌是最有效的生物膜形成生物之一,生物膜有助于保护微生物免受宿主防御并阻止抗菌药物的有效渗透。生物膜的形成被认为是引发和建立金黄色葡萄球菌慢性感染的一个重要因素,并且被认为是金黄色葡萄球菌感染治疗的一个主要障碍是它们对抗菌素产生耐药性的能力。目的:筛选包括MRSA在内的临床金黄色葡萄球菌的生物膜形成能力及其与抗微生物药物耐药性的关系。方法:采用标准微生物学技术,从加沙地带3家主要医院的不同样品来源获得临床分离的金黄色葡萄球菌196株。采用组织培养平板法(TCP)和试管贴壁法(TM)测定分离菌株的生物膜形成情况。根据临床和实验室标准协会的指南,采用改良的Kirby-Bauer纸片扩散法进行抗菌药敏试验。采用头孢西丁圆盘试验检测MRSA。结果:采用TCP法和TM法分离的金黄色葡萄球菌分别有174株(88.8%)和145株(74.0%)形成生物膜。耐药率最高的是青霉素(92.9%),其次是头孢西丁(80.6%)和奥西林(67.9%),耐药率最低的是利奈唑胺和头孢他林(1%)。196株中71.4% (N=140)为MDR, MAR指数≥0.2。共检出158株(80.6%)MRSA,分别来自Al-Shifa、Al-Nasser儿科和Al-Aqsa医院,分别占90.4%、79.4%和70.9%。大部分(82.1%)生物膜生产者被鉴定为MRSA。产生生物膜的MRSA比不产生生物膜的MRSA(9.5%)有更高的百分比(90.5%)。重要的是,89.2%的产生物膜金黄色葡萄球菌具有多重耐药性。结论:金黄色葡萄球菌具有较高的生物膜形成能力。产生生物膜的菌株有很高的耐药性、耐多药和耐甲氧西林的倾向。定期监测金黄色葡萄球菌的生物膜形成及其抗菌素耐药性可能会使金黄色葡萄球菌感染的治疗更成功。关键词:生物膜,耐多药,MRSA, TCP, TM,加沙地带,巴勒斯坦

Background: Pseudomonas aeruginosa is a pathogenic organism responsible for frequent wound and nosocomial infections worldwide. Its infections are difficult to control since the organism is known to rapidly develop antibiotic resistance and becomes multidrug-resistant (MDR) during treatment of patients. Aim of the study: This study was intended to investigate the occurrence of certain important types of (ESBL) and (MBL) enzymes in association with important specific virulence factors  associated with P. aeruginosa clinical isolates from Khartoum, Sudan. Methods: This study investigated 70 P. aeruginosa isolates which were collected from patients admitted to four major hospitals in Khartoum  (Fedail, Ribat, Ibn Sina and Soba hospitals). These isolates were recovered from 40 wound swabs (57.1%), 27 urine samples (38.6%), and 3 pleural fluid samples (4.3%) of patients. Higher numbers of isolates were recovered from males 42 (60%) than in females 28 (40%). All P. aeruginosa isolates were first confirmed by conventional biochemical and second using molecular PCR tests.   PCR methods were also used for detecting the presence of the virulence genes ToxA, AlgD, LasB, exoS, exoU, CTX, GES-1, and genes of VIM, IMP, KPC, CTX, VEB-1 and SHV-1. Results:   Antimicrobial susceptibility testing of P. aeruginosa isolates showed a high resistance to azetronam 49 (70%), followed by ceftazidime 32 (45.7%), 16 ciprofloxacin (22.9%), gentamicin 13 (18.6 %), piperacillin-tazobactam 11 (15.7%), amikacin 9 (12.9 %), and imipenem 6 (8.6%) showed the least resistance. All isolates were positive for algD and lasB (100%), followed by toxA (90%), exoS (34.3), exoU (24.3%), respectively. The rates of detected ESBL genes blaTEM, blaCTX-m, blaSHV-1,GES-1, were 3.3%, 6.6%, 10%, 3.3%,10%, respectively, but all isolates were negative for bla-KPC and bla- VIM and IMP . The percentages of pigment production were 61.4% for pyocyanin, 37.1% for pyoverdin and 1.4% for pyorubin. Conclusion: The study demonstrated high rates of antimicrobial resistance markers to most commonly used antibiotics in treatment of P. aeruginosa infections. The majority of the isolates from urine and wound samples carried at least three potential virulence factor genes of algD, lasB and toxA and without any significant relation to their antimicrobial resistance markers.
背景:铜绿假单胞菌是世界范围内常见的伤口和医院感染的病原菌。它的感染很难控制,因为已知这种生物在治疗患者期间会迅速产生抗生素耐药性并产生多重耐药性(MDR)。研究目的:本研究旨在调查与苏丹喀土穆铜绿假单胞菌临床分离株相关的某些重要类型(ESBL)和(MBL)酶的发生与重要的特异性毒力因子的关系。方法:对喀土穆4家主要医院(Fedail、Ribat、Ibn Sina和Soba医院)住院患者分离的70株铜绿假单胞菌进行分析。从40例患者伤口拭子(57.1%)、27例患者尿液(38.6%)和3例患者胸膜液(4.3%)中检出分离菌。雄42株(60%)的分离株数量高于雌28株(40%)。所有铜绿假单胞菌分离株首先用常规生化方法进行鉴定,然后用分子PCR方法进行鉴定。采用PCR方法检测毒力基因ToxA、AlgD、LasB、exoS、exoU、CTX、GES-1以及VIM、IMP、KPC、CTX、VEB-1和SHV-1基因的存在。结果:铜绿假单胞菌对头孢他啶32(45.7%)、环丙沙星16(22.9%)、庆大霉素13(18.6%)、哌拉西林-他唑巴坦11(15.7%)、阿米卡星9(12.9%)、亚胺培南6(8.6%)的耐药性最高。所有分离株algD和lasB阳性(100%),其次是toxA(90%)、exoS(34.3)和exoU(24.3%)。blblem、blaCTX-m、blaSHV-1、GES-1基因检出率分别为3.3%、6.6%、10%、3.3%、10%,bla- kpc、bla- VIM、IMP均阴性。色素产率分别为pyocyanin 61.4%、pyoverdin 37.1%和pyyorubin 1.4%。结论:在铜绿假单胞菌感染的治疗中,常用抗生素的耐药率较高。从尿液和伤口样本中分离的大多数菌株至少携带algD、lasB和toxA三种潜在毒力因子基因,且与它们的耐药标记物无显著相关性。

Introduction: Antibiotics are well known and recommended as the main therapy for preterm premature rupture of membranes (PPROM.) But the research on antibiotics other than the recommended macrolides regimens is still lacking. This research aims to evaluate whether there are effects differences of cefotaxime and ceftriaxone given on pregnancy with PPROM by comparing the duration of the latency period and the infants outcomes. Material and Methods: Data was taken retrospectively through medical records at Dr. Soetomo Surabaya General Hospital, Indonesia during the period of January-December 2017. The inclusion criteria were a history of PPROM in pregnancy <37 weeks, given cefotaxime or ceftriaxone therapy, and have labor data. The analysis was performed by the Mann-Whitney comparison test for the latency period and Fisher's exact test for infant outcomes. Results: There were 52 samples obtained. The antibiotics used were cefotaxime 3x1gr (A) and ceftriaxone 2x1gr (B). The results of the analysis showed that there were no significant differences between the types of antibiotics with the length of the latency period, with a value of p = 0,601 (p>0,05), where group A had a median of 52,67 hours and group B was 34,17 hours. Group A was found to be more able to extend the latency period for >48 hours with a percentage of 57,8%, whereas in group B only 42,9%. There are no significant differences in infant outcomes; infant birth weight and Apgar score among the two therapies used. Conclusion: Cefotaxime was more preferably to be used in the Dr. Soetomo Surabaya General Hospital. Nevertheless, ceftriaxone can still be a good choice for PPROM therapy since both cephalosporins have succeeded in preventing infections in women with PPROM.
简介:抗生素是众所周知的,并被推荐作为早产胎膜早破(PPROM)的主要治疗方法。但是,除了推荐的大环内酯类药物外,对抗生素的研究仍然缺乏。本研究旨在通过比较潜伏期的长短和婴儿结局,评价头孢噻肟和头孢曲松对PPROM妊娠的影响是否存在差异。材料和方法:通过2017年1月至12月期间印度尼西亚Soetomo泗水总医院的病历回顾性获取数据。纳入标准为妊娠PPROM史(0.05),其中a组的中位数为52,67小时,B组的中位数为34,17小时。发现A组更能延长潜伏期>48小时,比例为57.8%,而B组仅为42.9%。婴儿结局没有显著差异;婴儿出生体重和阿普加评分。结论:泗水苏莫医生总医院更适宜使用头孢噻肟。尽管如此,头孢曲松仍然是PPROM治疗的一个很好的选择,因为两种头孢菌素都成功地预防了PPROM妇女的感染。

Background:  Onychomycosis is a critical medical problem. This fungal infection of the nails leads to disfigurement, pain and impaired quality of life.  Given that it requires long-term expensive therapy; a proper diagnosis of this infection is greatly demanded.  Hence, study aimed at investigating the different laboratory methods used in the identification of dermatophytes implicated in onychomycosis including conventional laboratory methods (KOH preparation), Culture and PCR (multiplex). Subjects and Methods: This cross-section study included sixty-one (61) patients [ 82% females and 18% males]. All collected samples were investigated using microscopic examination and cultivation of samples. In addition, DNA extraction and PCR amplification were evaluated. Results: Distal and lateral subungual onychomycosis(DLSO) was the most common clinical types of onychomycosis represented 70 % of total cases. Pain was the most common presenting symptoms. Among the studied group, the most common fungal infections encountered were chronic paronychia, tinea pads and tinea manum (37.7%, 16.4%, and 8.2%) respectively. The 67.2% of the studied group by PCR were +ve, by culture 60.7% were +ve and finally, 73.8% were +ve by direct smear. The sensitivity of PCR in the diagnosis of lesions was 100% specificity was 83.3% and accuracy was 93.4%. Conclusion: The dermatophyte responsible for a majority of cases of onychomycosis. However, the role of NDMs should not be ignored and this may be now a consideration in evaluating and treating onychomycosis. PCR is highly sensitive methods for diagnosis of fungal infection. The application of PCR technology directly to the clinical specimens will allow early and accurate diagnosis of onychomycosis. This will permit prompt and targeted initiation of antifungal therapy. So, it is recommended to be used in the rapid diagnosis of onychomycosis.
背景:甲真菌病是一个严重的医学问题。这种指甲的真菌感染会导致毁容、疼痛和生活质量受损。考虑到它需要长期昂贵的治疗;迫切需要对这种感染作出正确的诊断。因此,本研究旨在探讨用于鉴定与甲真菌病有关的皮肤真菌的不同实验室方法,包括传统实验室方法(KOH制备),培养和PCR(多重)。对象和方法:本横断面研究纳入61例患者[82%女性,18%男性]。所有收集的样品采用显微镜检查和样品培养进行调查。并对DNA提取和PCR扩增进行评价。结果:远端和外侧甲下甲真菌病(DLSO)是临床上最常见的甲真菌病类型,占全部病例的70%。疼痛是最常见的症状。在研究组中,最常见的真菌感染是慢性甲沟炎、足癣和手足癣(分别为37.7%、16.4%和8.2%)。PCR检测阳性率为67.2%,培养检测阳性率为60.7%,直接涂片检测阳性率为73.8%。PCR诊断病变的敏感性为100%,特异性为83.3%,准确性为93.4%。结论:甲真菌病主要由皮肤真菌引起。然而,ndm的作用不应被忽视,这可能是现在评估和治疗甲癣的一个考虑因素。PCR是诊断真菌感染的高灵敏度方法。将PCR技术直接应用于临床标本,可以早期准确诊断甲癣。这将允许及时和有针对性地开始抗真菌治疗。因此,推荐用于甲真菌病的快速诊断。

Background: Lower respiratory tract infections (LRTIs) are a major cause of morbidity and mortality globally. The World Health Organization (WHO) estimates that LRTIs are the most common global cause of death from infectious diseases. However, the specific etiologic agent associated with LRTI is often unknown. We determined the bacterial infections and seasonal patterns associated with LRTIs among hospitalized cases at Jordan University Hospital (JUH) for a period of five years. Methods: We conducted a retrospective multi-year study among hospitalized patients in Jordan on LRTI-associated bacterial etiology. Results: We found bacterial infections among 105 (21.1%) out of 495 LRTI patients. The most frequently identified bacteria in the LRTI patients were Staphylococcus aureus (7.7%) followed by Pseudomonas aeruginosa (5.1%). Most of the LRTI patients (95.2%) had at least one chronic disease and many were admitted to the Intensive Care Unit (16.8%). Of the 18(3.64%) patients with LRTIs who died at the hospital, 2 had a bacterial infection. We noticed a seasonal pattern of bacterial infections, with the highest prevalence during the winter months. Conclusions: Our findings suggest that early identification of bacterial agents and control of chronic disease may improve clinical management and reduce morbidity and mortality from LRTIs.
