Nanoarchitectures for efficient IgE cross-linking on effector cells to study amoxicillin allergy.

Background: Amoxicillin (AX) is nowadays the β-lactam that more frequently induces immediate allergic reactions. Nevertheless, diagnosis of AX allergy is occasionally challenging due to risky in vivo tests and non-optimal sensitivity of in vitro tests. AX requires protein haptenation to form multivalent conjugates with increased size to be immunogenic.

Dendrimeric Antigens for Drug Allergy Diagnosis: A New Approach for Basophil Activation Tests.

Dendrimeric Antigens (DeAns) consist of dendrimers decorated with multiple units of drug antigenic determinants. These conjugates have been shown to be a powerful tool for diagnosing penicillin allergy using in vitro immunoassays, in which they are recognized by specific IgE from allergic patients. Here we propose a new diagnostic approach using DeAns in cellular tests, in which recognition occurs through IgE bound to the basophil surface.

Pseudomonas aeruginosa isolates and their antimicrobial susceptibility pattern among catheterized patients at Jimma University Teaching Hospital, Jimma, Ethiopia.

Background: Pseudomonas aeruginosa is among the most common bacterial pathogens with wide spread distribution in health care settings. Despite advances in medical and surgical care and introduction of wide variety of antimicrobial agents, Pseudomonas aeruginosa continues to cause life threatening infection. Thus, this study aims to isolate and determine antimicrobial susceptibility patterns of Pseudomonas aeruginosa from catheterized patients with urinary tract infection.
