The core region of the lipopolysaccharides of Proteus group OX bacteria, which are used as antigens in Weil-Felix test for serodiagnosis of rickettsiosis, were studied by chemical degradations in combination with ESI FTMS, including infrared multi-photon dissociation (IRMPD) MS/MS and capillary skimmer dissociation. Structural variants of the inner core region were found to be the same as in Pr...

Three cases of Proteus empyema were associated with elevated pleural fluid pH values. The elevated pH is likely due to ammonia production by Proteus organisms.

In routine bacteriology the swarming of Proteus on plate cultures often masks the identity or presence of other bacteria which may be present. Mixed cultures including Proteus are often obtained from open wounds or sinuses following abdominal or chest operations, so that unless some special selective medium is used it is usually impossible to identify or to isolate other bacteria from a culture...

BACKGROUND Proteus species cause a variety of community- and hospital-acquired illnesses. Synthesis of β-lactamases is the predominant mechanism for resistance to β-lactam antibiotics. Among the β-lactamases, extended spectrum β-lactamases (ESBLs) and AmpC β-lactamases are the most common. AIM The objective of this study was to determine the occurrence of ESBL and AmpC β-lactamases in Proteus...

Retrograde pyelonephritis was produced in rats by the intravesical injection of Proteus mirabilis. When animals were preimmunized against Proteus mirabilis by (a) prior infection, (b) administration of antigen, or (c) passively transferred antiserum, they were resistant to infection by proteus when challenged by the retrograde route. The protective effect of specific preimmunization in retrogra...

Proteus syndrome is an extremely rare genetic disorder characterized by an asymmetrical overgrowth of skin, bones, muscles, fatty tissues, and blood and lymphatic vessels. We present a case of a six-year-old boy with proteus syndrome who underwent bone scintigraphy for suspected osteomyelitis. Bone scintigraphy ruled out osteomyelitis and suggested cellulitis. In addition, it demonstrated strik...

Tigecycline is an important agent in clinical practice because of its broad-spectrum activity. However, it has no activity against Pseudomonas or Proteus species. We conducted a case-control study to analyze risk factors for the acquisition of Pseudomonas or Proteus spp. during tigecycline therapy. Placement of suction drainage at infected wound sites, ICU stay, and neurologic disease were iden...

Proteus syndrome is a rare overgrowth syndrome characterized by hemihypertrophy, lower limb asymmetry, hyperpigmentations, lipomas, and vascular malformation. In this paper, we present a new adolescent Proteus syndrome patient with bilateral megafoot. He was very successful in playing football and was very popular among his friends. We present this case for the psychological and surgical aspect...

The Proteus syndrome comprises an association of asymmetrical overgrowth of almost any part of the body, verrucous epidermal naevi, vascular malformations and lipoma-like subcutaneous hamartoma. Both sexes are affected with equal frequency and severity and it is not transmitted genetically. Here a 16-year-old man with asymmetric overgrowth of the extremities, macrodactyly, cerebriform hypertrop...
