Klebsiella spp. are opportunistic pathogens which can cause severe infections, are often multi-drug resistant and are a common cause of hospital-acquired infections. Multiple new Klebsiella species have recently been described, yet their clinical impact and antibiotic resistance profiles are largely unknown.

The aim of the present study was to determine the phenotypic resistance pattern to βlactam antibiotics among Escherichia coli clinical isolates and to identify the genetic determinants responsible for β-lactam antibiotic resistance. Forty Escherichia coli isolates were included in this study. Identification of tested strains was confirmed using MALDITOF/MS. Phenotypic and genotypic β-lactamase patterns were investigated.

Kininogens are multifunctional proteins found so far mainly in mammals. They carry vasoactive kinins as well as participate in defense, blood coagulation and the acute phase response. In this study, novel kininogens were isolated from Atlantic cod (Gadus morhua L.) and spotted wolffish (Anarhichas minor) by papain-affinity chromatography. The molecular mass of cod kininogen determined by MALDITOF mass spectrometry to be 51.0 kDa and it had pI values of 3.6, 3.9 and 4.4.

If you read March’s paper on ion traps: – What is resonant excitation? Summarize how resonant excitation is used in typical ion trap MS experiments. If you read the Russell and Edmondson paper on MALDITOF and accurate mass: – Summarize the advantages and disadvantages of MALDI-TOF (with DE and reflection) versus FTICR (including ESI-FTICR), especially in biochemical applications.
