The World Health Organization declared COVID-19 as a pandemic on the 11 th of March 2020. Since then, many efforts are being carried out to contain the virus. Knowledge and attitude of people should be directed towards strict preventive practices in order to halt the spread of the virus. The aim of the current cross-sectional study is to assess the knowledge, practice and attitude of university students from medical and non-medical colleges in Jordan using a structured questionnaire involving a total number of 592 students. A positive response regarding the overall knowledge about the symptoms of COVID-19 was observed in more than 90% of the students. In response to the attitude and practice, a good number of students nearly 99.7% agreed that hand washing is necessary for prevention of infection whereas 68.4% believed that mask wearing would prevent the infection. Around 6-7% students considered the virus as a stigma hence would not visit hospital. Also, around 10% students believed that their religious beliefs and body immunity might protect them from infection. More dangerously, 20.6% and 19.2% students believed antibiotics and smoking to be a protective measure against the infection respectively. Also, 96.8% do avoid hand shaking, 98.8% wash their hands and 93.3% use alcoholic rub, 95.8% cough or sneeze in a tissue and dispose it in waste bin, 51% will drink ginger with honey and 42.7% eat garlic for infection prevention. The main sources of knowledge were social media, internet and television. No significant difference was noticed between medical and non medical colleges. Thus, there is a need for more detailed and directed measures and awareness campaigns to improve the knowledge, attitude and practice in some critical aspects to contain the virus.
Asymptomatic carriage of methicillin-resistant Staphylococcus aureus (MRSA) can predispose the host to a wide range of infections. To inform public health strategies, this study sought to determine the prevalence and the phenotypic and genotypic characteristics of MRSA from nasal swabs of health care workers (HCWs) and other healthy individuals in Jordan. Overall, 716 nasal swabs were collected from 297 HCWs, 141 adults and 278 children in the community. MRSA was recovered from 56 (7.8%) nasal swabs, which represented carriage rates of 10.1%, 4.3% and 7.2% among HCWs, adults and children, respectively. The MRSA isolates were resistant to oxacillin (100%), erythromycin (42.8%), tetracycline (37.5%), clindamycin (5.3%), fucidin (5.3%), and ciprofloxacin (3.5%). A total of 17 different spa types belonging to eight different clonal complexes (CCs) were identified. All isolates were mecA positive, and mecC-MRSA was not detected. Analysis of the staphylococcal cassette chromosome mec (SCCmec) elements revealed that the majority (54; 96.4%) of the samples harbored the smaller type IV and V elements (the most common were SCCmec IVa or IVc, and there were two each of the IVg and V elements), and two were nontypable. The genes for Panton-Valentine leukocidin (luk-PV) were detected in 5.4% of the study isolates. A tst-positive, CC22-MRSA-SCCmecIVa clone (spa type t223) was identified as the dominant MRSA lineage among the nasal carriage isolates from both HCWs and other individuals (adults and children) in the community. These findings provide important information for public health personnel for the formulation of effective infection prevention and control strategies. Studies to further our understanding of the distribution, pathogenicity, transmissibility and fitness of this lineage would be prudent.
Introduction: A high rate of infections with methicillin-resistant Staphylococcus aureus (MRSA) has been documented, in both hospital-(HA-MRSA) and community-acquired (CA-MRSA) diseases in Jordan. Erythromycin and clindamycin are considered treatments of choice. However, resistance to erythromycin with false susceptibility to clindamycin in vitro may lead to therapeutic failure. Hence, it is mandatory to study the prevalence of inducible resistance to macrolide-lincosamide-streptogramin B (iMLSB) antibiotics conferred by erm genes in those bacteria. Methodology: S. aureus isolates were identified morphologically and biochemically, and MRSA were appraised using standard procedures. Induction in resistance to MLSB antibiotics among MRSA isolates was detected phenotypically using the D-test, and the presence of erm genes was revealed by polymerase chain reaction (PCR). Results: Of 126 collected Staphylococcus isolates, 71 (56.3%) isolates were S. aureus, of which 55 (77.5%) were MRSA. A total of 43 (78.2%) MRSA-discordant isolates were resistant to erythromycin, of which 33 (76.7%) exhibited the iMLSB (D-test positive), 2 (4.7%) the MSB (Dtest negative), and 8 (18.6%) the constitutive resistant (cMLSB) phenotypes. Induction of clindamycin resistance was 1.6 times greater in CA-MRSA than in HA-MRSA. Furthermore, ermA and ermC were significantly prevalent in HA-MRSA and CA-MRSA, respectively. Conclusions: Continuous surveillance of the MLSB resistance is important and required before the prescription of clindamycin to treat MRSA infections.
This is the first study to assess the MRSA prevalence among children aged 6-11 years in Jordan. The prevalence in community children is within the range compared with other studies in other countries. The antibiogram, SCCmec and Spa types of the isolated MRSA are much similar to what was found previously in Jordan. However, all isolates were PVL toxin negative. The study recommends increasing the public awareness of MRSA and the proper antibiotics dispensing. Future studies to follow-up on the changing epidemiology of the CA-MRSA in Jordan are also recommended.
Staphylococcal infections have high occurrence in Jordanian patients. This study was carried out to determine the rates of high- and low-level mupirocin resistance (MupH and MupL) among staphylococci with the molecular characterization. Two hundred and thirty-two non-duplicate Staphylococcus spp. isolated from different clinical specimens were tested for mupirocin susceptibility using disk diffusion method and minimum inhibitory concentration (MIC). Resistance genes and clone relatedness was studied using polymerase chain reaction (PCR) and enterobacterial repetitive intergenic consensus primers (Eric-PCR) for the latter. Plasmid curing was performed to determine the genetic location of MupA gene. Among the 232 strains, 144 (62%) were methicillin-resistant Staphylococcus aureus (MRSA), 33 (14.2%) methicillin-susceptible Staphylococcus aureus (MSSA) and 55 (23.7%) were of other coagulase-negative Staphylococcus spp. (CoNS). Of all strains tested, only 6 (2.6%) were mupirocin resistant. MecA gene was detected in both MupL and MupH strains but MupA gene was only detected in MupH. Plasmid curing improved the plasmidic location of MupA gene. Molecular typing by Eric-PCR method revealed heterogenicity of the genetic make up of our MupL and MupH strains. Staphylococci with MupA-carrying genes are present in Jordanian hospitals, but thank to the limited use of mupirocin, they remain rare.
Little is known of carbapenemase producing Klebsiella pneumoniae (CPK) in Jordan. This study aimed to determine the prevalence of CPK in a major hospital in Amman, Jordan in 2012-2013 and to characterize the isolates and detect the types of carbapenemase(s) they produced. For the 296 isolates investigated, species identification and antimicrobial susceptibilities were determined (Vitek II, bioMérieux). Isolates with decreased ertapenem susceptibility were tested for carbapenemase production using the Modified Hodge Test. Isolates with a carbapenemase-positive phenotype were characterized further via multiplex PCRs for extended-spectrum β-lactamase and carbapenemase genes and by Pulsed Field Gel Electrophoresis (PFGE). Seven of 296 K. pneumoniae isolated in 2012-2013 (2.4%) were carbapenemase producers, five produced class D carbapenemases (OXA-48-like) and two produced a NDM metallo-beta-lactamase. All seven isolates also encoded CTX-M enzymes; CTX-M-1-like enzymes were detected in five isolates (two co-producing NDM enzymes and three co-producing OXA-48-like enzymes), CTX-M-9 was found in the two remaining OXA-48-like producers. PFGE revealed five genetically distinct types amongst the seven carbapenemase producing K. pneumoniae, with two pairs of identical isolates associated with patients treated on the same wards. The emergence of OXA-48-like and NDM carbapenemases associated with multi-drug resistant (MDR) isolates in Jordan is concerning. The strict implementation of infection control practices will help to disrupt the spread of MDR carbapenemase producers in Jordanian hospitals.
