Diversity of MRSA SCCmec elements in Pretoria region of South Africa: The problem of variation in the assigned SCCmec types by different multiplex-polymerase chain reaction (PCR) methods and a call for an African consensus
The SCCmec element is one of the recommended targets for MRSA characterization and several multiplex-PCR SCCmec typing methods have been developed over the past years. However, there are no data on the consistency of the SCCmec types in clinical isolates as detected by these methods. Using different previously published, commonly used M-PCR methods, this report describes the diversity of SCCmec elements in MRSA isolates...

Systemic elicitation of defense related enzymes suppressing Fusarium wilt in mulberry (Morus spp.)
Antagonist and organic amendments based bioconsortia (seri bed waste+Pf1+Bs4+Th1+neem cake) was found to lead the restriction of Fusarium solani pathogen in mulberry roots mainly by inducing inherent defense enzymes. Induction of defense enzymes such as peroxidase, polyphenoloxidase, phenylalanine ammonia lyase, phenols, catalase and superoxide dismutase, was studied in mulberry plants pretreated with bioconsortia and...

Special biochemical profiles of Escherichia coli strains isolated from humans and camels by the VITEK 2 automated system in Al-Ahsa, Saudi Arabia
The VITEK 2 automated system was used for comparing biochemical characteristics of Escherichia coli isolates from human urinary tract infections (UTIs) and camel faecal samples for the first time in the study area. Identification by the system to the species level was accurate. Recovery rate of E. coli from camel specimens was 26% and for human specimens was 33%. Based on biochemical activities, human and animal strains...

Microbial safety criteria and quality of traditional Egyptian Karish cheese
Some traditional fermented dairy products like Egyptian Karish cheese and traditional fermented milk (Laban Zeer) are manufactured in farmhouses following traditional techniques using raw milk without heat treatment or addition of selected starter cultures, these products are generally designed as “artisanal”. The representative Karish samples were analyzed for their content of total microbial,...

Outbreak of Burkholderia cepacia complex associated with contaminated liquid soap for hospital use: A case study
Burkholderia cepacia complex (BCC) is gram negative bacteria which causes different types of human infections including catheter-associated infections and respiratory tract infections especially in immunocompromised patients. This study was conducted to decide the source, to prevent the possible hospital outbreak of BCC and to determine the epidemiological source. Eleven cartridge of liquid soaps were purchased by...

Antibacterial activity Lactobacillus plantarum isolated from fermented vegetables and investigation of the plantaricin genes
Escherichia coli and Staphylococcus aureus are two food pathogens that cause severe food poisonings. Another problem found on a global level is the continuous increase of antimicrobial resistance in bacteria isolated from food. This study aimed to evaluate the antibacterial activity of Lactobacillus plantarum against pathogenic bacteria including E. coli and S. aureus and to study if L. plantarum with antibacterial...

Anti-HSV type-1 activity of olive leaves extract crude form acting as a microemulsion dosage form
Olea europeae (L.) has been reported to have antibacterial, antifungal and antiviral activities. The aim of the present study is to evaluate antiviral activity of olive leaves extract (OLE) against herpes simplex viruses (HSV) type-1 virus. Screening of antiviral activity was assessed by measuring inhibition of viral-induced cytopathic effect of in vero cells of different OLE fractions that have been successively...

Virulence factors and antibiotic susceptibility patterns of multidrug resistance Klebsiella pneumoniae isolated from different clinical infections
Many strains of Klebsiella pneumoniae can produce several virulence factors, such as siderophores, capsules, fimbrial adhesins and antibiotic resistance enzymes, which are important in the adherence, colonization, invasion and development of the infection. Therefore the aim of this study was to investigate ten virulence gens in 32 K. pneumoniae isolated from different clinical infections: urine (13), burns (12), sputum...
