Some of them are resistant to Vancomycin(VRE) and some are susceptible to Vancomycin (VSE). The present study was carried out to identify enterococci from clinical cases and to illustrate their clinical features and drug resistance characteristics. Antibiotics susceptibility of the identified bacteria was determined by disk diffusion method and E-test. Drug resistance properties were evaluated against ampicillin, gentamicin, vancomycin, teicoplanin and linezolid. Relating to clinical features, 244 cases of enterococci infected patients were identified at hospital Kuala Lumpur (HKL) Malaysia based on clinical information from the hospital. Of the patients 21% had history of urinary tract infections, 17.2% end stage renal disease, 12.2% sepsis, 8.4% malignancy, 12.2% had head injury and neurological problems, 4.2% diabetes mellitus and other clinical manifestations .In case of Vancomycin resistant enterococci infection, the clinical features of the patients were: end stage renal failure 3/6 (50%) and others with diabetes mellitus, interstitial lung disease and nephrotic syndrome. The patients of the enterococci infections were more prevalent in nephrology-urology unit (39%) and medical wards (including ICU, 23%) The findings would serve as an alert to the clinicians of the emergence of infections by enterococci and encourage implementation of appropriate infection control measures in order to curb further rise in prevalence.","PeriodicalId":22514,"journal":{"name":"The Internet journal of microbiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78268161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aureus) is the most common species of staphylococci to cause Staph infections. The infections caused by S. aureus were not difficult to manage. However, in recent past, S. aureus is transformed to its variant forms, including, Methicillin-resistant S. aureus (MRSA) by acquiring methicillin resistant gene (mec A gene). Previously, the MRSA was known for its origin from hospitals, but more recently, it is known to be acquired, from the communities too. Here we report the case presentation of a male adolescent with complicated fibular osteomyelitis, necrotizing fasciitis and deep vein thrombosis caused by Community acquired (CA) MRSA. The preliminary complaint of the patient was swelling in right foot and leg associated with high fever, pain, dyspnea and cough. The clinical presentation fit him as acute respiratory distress syndrome and hence antibiotics (ceftixone and vancomycin) were started. Doppler ultrasound revealed deep vein thrombosis (DVT). Analysis of blood culture showed the presence of MRSA. Hence rifampin and gentamicin were added and ceftrixon was discontinued. MRI revealed ostiomyelitis in the distal part of fibula. The bone infection was so severe that despite of using the three antibiotics, the patient remained febrile with increased leukocytes and neutrophills, the ankle redness became confined with malleollus on each side and the sepsis remained uncontrollable. Repeated MRI showed inflammatory findings, including cellulitis, pyogenic myositis, deep fasciitis and fibular periosteal reactions, suggestive of necrotizing fasciitis. Upon confirmation of fasciitis, fasciotomy with debridement and irrigations was done in multiple sessions and a high dose intravenous immunoglobulin was administered as an adjuvant therapy, resulting in reversal of the disease progression. In light of reports in the literature, we replaced antibiotics with immunoglobulins as a post surgery treatment, which worked well.","PeriodicalId":22514,"journal":{"name":"The Internet journal of microbiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76988035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aims: To determine the prevalence of inducible clindamycin resistance in clinical isolates of Staphylococcus spp. and the susceptibility pattern of the isolates. Materials and Methods: A total of 300 isolates of Staphylococci spp. recovered from different clinical specimens were studied. All the Staphylococcus spp. were identified by conventional microbiological methods. Inducible clindamycin resistance was detected by double disk approximation test (Dtest).Results: Of the 300 isolates, 176 were identified as S. aureus, while 124 were coagulase negative staphylococci (CoNS). The rates of inducible clindamycin resistance in methicillin resistant S. aureus (MRSA), methicillin sensitive S. aureus (MSSA), methicillin resistant CoNS (MR-CoNS) and methicillin sensitive CoNS (MSCoNS) were 75.0%, 24%, 18.8% and 11.1%, respectively. The inducible clindamycin resistance was significantly more among MRSA compared to methicillin sensitive S. aureus (MSSA) (P value < 0.0001). Majority of the MRSA isolates were susceptible to clindamycin, vancomycin and linezolid, while most of them were resistant to erythromycin, gentamicin, ciprofloxacin, tetracycline and sulfamethoxazole-trimethoprim. Conclusion: In view of the significant in vitro inducible clindamycin resistance in Staphylococcus spp., we recommend that D test should be used as a mandatory method in microbiology laboratories to avoid misinterpretation of clindamycin result.","PeriodicalId":22514,"journal":{"name":"The Internet journal of microbiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81085997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acute mouth lesions are improved by direct application of aloe vera gel on herpetic viral lesions, apthous ulcers and cracks occurring at corner of mouth. Denture patients with sore spots and ill fitting complete or partial dentures can benefit by the use of aloe vera.

For that 49 serologically negative dengue patients but clinically dengue like symptomms were included. Clinical investigation was carried out recording different profiles of hospitalized patients. Serology was performed using the Onsite® Chikungunya IgM Combo rapid test and molecular test RT-PCR was performed to detect the virus in the patients sera. It was observed that out of them 19 (38.7 %) were serologically confirmed chikungunya infection. Interestingly molecular detection of the patients sera did not show the presence chikungunya virus but detected dengue virus from 9 patients’s sera. Classical clinical features of chikungunya virus infected patients were recorded to differentiate chikungunya from dengue, which were fever, arthralgia, myalgia and rash. Detection of chikungunya IgM in these cohort means that this virus is circulating throughout the year although not as many as dengue. Laboratory confirmation is important to differentiate chikungunya fever from dengue fever. This study adds some information in local data and hopefully can help the clinicians to clinically and laboratory diagnosis and management of chikungunya infection in outbreak and non-outbreak setting. Serology was proven to be useful in confirming chikungunya infection.","PeriodicalId":22514,"journal":{"name":"The Internet journal of microbiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88659614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
