Atypical Presentation of Neurobrucellosis as Infection of Ventriculoperitoneal Shunt.

Brucellosis is a frequent zoonosis in some regions of the world and may cause various symptoms. Neurobrucellosis is a rare but serious complication of the infection. Our case report describes the course of neurobrucellosis in a patient who had received a ventriculoperitoneal shunt in his native country 13 years prior to diagnosis of brucellosis.

Relapse of typhoid fever following delayed response to meropenem: A case report and review of previously published cases indicating limited clinical efficacy of meropenem for the treatment of typhoid fever.

In times of emerging multi-drug resistance among Gram-negative bacteria (including , Serovar Typhi), we observed relapse of typhoid fever following delayed response to treatment with meropenem, suggestive for limited clinical efficacy of the drug. Three previously published cases supported our suspicion. Within this context, we discuss the case details with a focus on potential explanations for insufficient clinical response to meropenem (e.

The sword of Damocles for the splenectomised: death by OPSI.

The overwhelming post splenectomy infection (OPSI) in splenectomised patients is a rare but severe infection mostly caused by encapsulated bacteria. We analyse the case of a 65-year-old female patient who was presented with clinical and laboratory findings indicating gastroenteritis. Two years years before admission, the patient underwent a splenectomy for a two stage splenic rupture following resuscitation for pulmonary embolism.

Molecular analysis of constitutively expressed erm(C) genes selected in vitro by incubation in the presence of the noninducers quinupristin, telithromycin, or ABT-773.

A Staphylococcus aureus strain that harbored a plasmid-borne inducibly expressed erm(C) gene was cultivated in the presence of the noninducers quinupristin, telithromycin, and ABT-773. After overnight incubation, 78 mutants that displayed combined resistance to macrolides, lincosamides, streptogramin B antibiotics, and ketolides were analyzed for the genetic basis of this altered resistance phenotype. Because this resistance phenotype is indicative for constitutively expressed erm(C) genes, the erm(C) regulatory regions of all mutants were sequenced.

Molecular characterization of ketolide-resistant erm(A)-carrying Staphylococcus aureus isolates selected in vitro by telithromycin, ABT-773, quinupristin and clindamycin.

The aim of this study was to investigate whether a Staphylococcus aureus strain that carried an inducibly expressed erm(A) gene might exhibit resistance to the non-inducers telithromycin, ABT-773, clindamycin, quinupristin, dalfopristin or the combination quinupristin-dalfopristin after incubation in the presence of inhibitory concentrations of any of these compounds. Whenever resistant mutants were obtained, these were investigated for the molecular basis of the altered resistance phenotype. Resistant mutants were not selected with dalfopristin or quinupristin-dalfopristin, but were obtained with the other four agents.

Rickettsia felis infection acquired in Europe and documented by polymerase chain reaction.

We report the first case of Rickettsia felis infection in Europe to be documented by polymerase chain reaction (PCR) and serologic testing.

Distribution of macrolide-resistance genes in Staphylococcus aureus blood-culture isolates from fifteen German university hospitals. M.A.R.S. Study Group. Multicentre Study on Antibiotic Resistance in Staphylococci.

The purpose of the study was to analyze the distribution of the macrolide-resistance genes in 134 erythromycin-resistant Staphylococcus aureus blood-culture isolates collected at 15 German university hospitals. The most prevalent resistance gene was ermC (68/134; 50.7%), followed by ermA (52/134; 38.
