Extended-spectrum β-lactamase-producing Klebsiella pneumoniae in the neonatal intensive care unit: does vancomycin play a role?

Background: Extended-spectrum β-lactamase (ESBL)-producing Klebsiella species cause worldwide problems in neonatal intensive care units (NICUs). This study aimed to determine possible risk factors for infection or colonization with ESBL-producing Klebsiella pneumoniae (ESBLKp) during an outbreak in the NICU.

Methods: A retrospective cohort study was conducted among neonates admitted to the NICU of a teaching hospital in Riyadh, Saudi Arabia, during an outbreak of ESBLKp from April to July 2008.

Brucella spp isolated from respiratory sample and grown in Mycobacterium growth indicator tube (MGIT).

Brucellosis remains endemic in many countries including Saudi Arabia. The disinfection of objects and surfaces contaminated with Brucella spp is not difficult, but we encountered a situation in which the organism survived the decontamination and liquefaction procedure adopted for AFB culture. A sputum specimen from a patient was sent for TB culture and the BACTEC MGIT 960 system isolated an organism identified as Brucella spp.

Antimicrobial susceptibility patterns of multidrug-resistant Pseudomonas aeruginosa and Acinetobacter baumannii against carbapenems, colistin, and tigecycline.

Objective: To examine susceptibility of Pseudomonas aeruginosa (P. aeruginosa) and Acinetobacter baumannii (A. baumannii ) against carbapenems along with colistin and tigecycline as alternative therapeutic options.

Mycobacterium chelonae complex bacteremia from a post-renal transplant patient: case report and literature review.

In this report we present a case of a young lady with abdominal abscesses and septicemia caused by Mycobacterium chelonae complex. Identification of the organism and initiation of the appropriate antimicrobial therapy was delayed, resulting in significant morbidity and multiple hospital admissions. Gram staining of these organisms from blood culture can be easily overlooked or confused with either debris or diptheroids.

A review of gastrointestinal manifestations of Brucellosis.

Brucellosis is hyperendemic in the Kingdom of Saudi Arabia (KSA) with more than 8,000 cases reported each year to the public health authorities. The disease can affect almost any organ system in the body including the gastrointestinal system. In some instances, gastrointestinal manifestations may be the only presenting features of the disease.
