Impact of Gene Disruption: Decreasing Staphylococcal Biofilm and Alteration of Transcriptomic and Proteomic Profiles.

expresses diverse proteins at different stages of growth. The immunodominant staphylococcal antigen A (IsaA) is one of the proteins that is constitutively produced by during colonisation and infection. SACOL2584 (or ) is the gene that encodes this protein.

COVID-19 in Malaysia: exposure assessment and prevention practices among healthcare workers at a teaching hospital.

Introduction: During the second wave of the coronavirus disease 19 (COVID-19) pandemic, Malaysia reported several COVID-19 clusters related to healthcare workers. Thus, addressing and understanding the risk of exposure in healthcare workers is important to prevent future infection and reduce secondary COVID-19 transmission within the healthcare settings. In this study, we aim to assess exposure and prevention practices against COVID-19 among healthcare workers at the Hospital Canselor Tuanku Muhriz, a university teaching hospital based in Kuala Lumpur, Malaysia.

Non-tuberculous mycobacterium bacteraemia in a pregnant systemic lupus erythematosus (SLE) patient: a case review and pooled case analysis.

Non-tuberculous mycobacteria (NTM) are recognized as an important cause of human diseases and infections. It is commonly known to cause infections of the skin, soft tissue infections, and pulmonary infection as well as bacteraemia. We report a challenging case of severe mycobacterium abscessus bacteraemia in a pregnant lady with active systemic lupus erythematous (SLE).

Screening for New Delhi metallo-β-lactamase-1 in Enterobacteriaceae: Is there a role for the modified Hodge test?

Objective: The New Delhi metallo-β-lactamase-1 (NDM-1) enzyme is a plasmid-encoded enzyme that inactivates carbapenem antibiotics. This study aims to ascertain if the modified Hodge test (MHT) has a role in screening for NDM-1 in Enterobacteriaceae with reduced carbapenem susceptibility.

Methods: Over a period of one year, all Enterobacteriaceae isolates from all clinical specimens with reduced susceptibility to at least one carbapenem were subjected to MHT and conventional polymerase chain reaction (PCR) detection of the NDM-1 gene.

Molecular detection of the New Delhi metallo-β-lactamase-1 gene in Enterobacteriaceae isolates in a tertiary medical centre.

Background: New Delhi metallo-β-lactamase-1 (NDM-1) is a relatively recent carbapenemase enzyme that inactivates all β-lactam antibiotics with the exception of aztreonam. This study aims to ascertain the baseline prevalence and antibiotic susceptibility patterns of NDM-1-producing Enterobacteriaceae in a tertiary medical center in Malaysia.

Methods: Over a period of one year, all Enterobacteriaceae isolates from all clinical specimens with reduced susceptibility to at least one carbapenem and resistance to at least one third generation cephalosporin were subjected to antibiotic susceptibility testing by disk diffusion and molecular detection of the NDM-1 gene by single-target PCR followed by gel electrophoresis.

INFLUENZA VACCINATION UPTAKE AMONG HEALTHCARE WORKERS AT A MALAYSIAN TEACHING HOSPITAL.

Annual influenza vaccination is the most important preventive strategy against influenza illness in healthcare workers (HCWs), who could acquire influenza from and transmit influenza to patients and other HCWs. Despite the well established benefits and strong recommendations for influenza vaccination for all HCWs, influenza vaccination uptake at the Universiti Kebangsaan Malaysia Medical Centre (UKMMC) for the past 3 years has been low and is decreasing. We aimed to determine the factors associated with influenza vaccination uptake among HCWs at UKMMC.

Extremely high prevalence of antiseptic resistant Quaternary Ammonium Compound E gene among clinical isolates of multiple drug resistant Acinetobacter baumannii in Malaysia.

Background: Antiseptics are commonly used for the management of MDR (multiple drug resistance) pathogens in hospitals. They play crucial roles in the infection control practices. Antiseptics are often used for skin antisepsis, gauze dressing, preparation of anatomical sites for surgical procedure, hand sterilization before in contact with an infected person, before an invasive procedure and as surgical scrub.

Antibiogram for haemodialysis catheter-related bloodstream infections.

Background. Haemodialysis (HD) catheter-related bloodstream infections (CRBSIs) are a major complication of long-term catheter use in HD. This study identified the epidemiology of HD CRBSIs and to aid in the choice of empiric antibiotics therapy given to patients with HD CRBSIs.

Community-acquired methicillin-resistant Staphylococcus aureus in a Malaysian tertiary centre.

Abstract. Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) is a pathogen recognized to be distinct in both phenotype and genotype from hospital-acquired MRSA. We have identified CA-MRSA cases in Universiti Kebangsaan Malaysia Medical Centre, Kuala Lumpur, Malaysia, including their antibiotic susceptibility patterns and genotypic characteristics.
