Nanobody-based immunosensor for the detection of H. pylori in saliva.

Helicobacter pylori (H. pylori) infection is highly prevalent worldwide, affecting more than 43% of world population. The infection can be transmitted through different routes, like oral-oral, fecal-oral, and gastric-oral.

Novel spa type and antimicrobial resistance gene profiles of Staphylococcus aureus strains isolated from bovine mastitis in Jordan.

Staphylococcu aureus is the most prevalent microorganism associated with mastitis in cattle. This study was designed to determine the spa types of Staph. aureus and to assess the resistance genes profile of isolated strains in dairy farms in Jordan.

First molecular characterization of capsule expression and antibiotic susceptibility profile of isolates from bovine mastitis in Jordan.

Background And Aim: Bovine mastitis has long been considered the most important cause of economic losses in the dairy industry. is the most frequently isolated pathogen from bovine mastitis cases worldwide. Capsular polysaccharides (CPs) of serotype 5 (CP5) or serotype 8 (CP8) are the most prevalent capsule genotypes related to infections associated with in humans.

Molecular analysis for the OprD gene among Pseudomonas aueroginosa clinical isolates obtained from hospitals in Jordan.

Introduction: Pseudomonas aeruginosa has increasingly been associated with the emergence of antibiotic resistance. Antibiotic resistance among P. aeruginosa isolates is an ambiguous and complicated mechanism utilizing several enzymes and structural proteins.

Potential antimicrobial effect of plant essential oils and virulence genes expression in methicillin-resistant isolates.

Aim: This study aimed to investigate the antibacterial efficacy of eight commercially available essential oil (EO) blends and characterize the effect on the expression of some virulence genes against methicillin-resistant (MRSA).

Materials And Methods: evaluation of the antimicrobial effects of oils against MRSA was performed using the disk diffusion method and by measuring the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC). The EOs (A-F) were contained (β-pinene, carvacrol, carvone, dimethyl trisulfide, linalool, limonene, menthol, monoterpene hydrocarbons, and thymol) in different amounts.

Antimicrobial resistance and putative virulence genes of isolates from patients with respiratory tract infection.

Introduction: is a common agent causing community acquired and nosocomial respiratory tract infections, with particularly life-threatening manifestations in patients who are immunocompromised of who have cystic fibrosis. This study investigated the occurrence of extended-spectrum β-lactamases (ESBLs) and metallo β-lactamase (MBL) in association with important putative virulence genes and genotypes variation among isolates from respiratory tract infection of Jordanian patients.

Methods: Over a period of 8-month, a total of 284 respiratory tract samples were obtained from patients diagnosed with respiratory tract infection while attending the Pulmonary Clinic/Intensive Care Unit, Jordan University Hospital (JUH).

Major characteristics of Staphylococcus aureus colonizing Jordanian infants.

Background: Colonization of infants with methicillin-resistant Staphylococcus aureus (MRSA) carries specific toxin genes. In particular, Panton-Valentine leukocidin (PVL) are a risk factor for subsequent infection during hospitalization. This prospective study investigated important epidemiological characteristics of Staphylococcus aureus colonizing the nares and intestines of Jordanian infants.

Identification of differentially expressed small non-protein-coding RNAs in Staphylococcus aureus displaying both the normal and the small-colony variant phenotype.

The emerging interest in RNA research is due to the discovery that bacterial non-protein-coding RNAs (npcRNAs; often referred to as "non-coding RNAs") are central regulatory molecules. While single npcRNAs have been described in Staphylococcus aureus, mostly based on computational-based approaches, experimental data on npcRNAs and their impact on the formation of different phenotypes of S. aureus are missing.
