The effect of bacterial infection on excised renal papillae as a model for papillary necrosis and subsequent calcification was investigated. Sterile rat renal papillae were placed in 25 ml aliquots of filter sterilized human urine and then inoculated with one ml suspensions of sterilized human urine
The biological activity of lipopolysaccharide (LPS) obtained from Proteus mirabilis smooth and rough strains was investigated. The tested endotoxins (differing in polysaccharide chain lenght) were isolated from wild S1959 strain as well as from its rough mutants Ra and Re. Induction of tumor
Proteus mirabilis, a significant cause of bacteriuria and acute pyelonephritis in humans, produces urease. This high-molecular-weight, multimeric, cytoplasmic enzyme hydrolyzes urea to ammonia and carbon dioxide. To assess the role of urease in colonization, urolithiasis, and acute pyelonephritis in
This study aimed to analyze the proinflammatory cytokine mRNA expression in the urinary tract of BALB/c mice infected with bacterial strains with uropathogenic potential. Groups of four 6-week-old female BALB/c mice were intraurethrally inoculated with 5 × 107 colony-forming units (CFU)
The Waterhouse-Friderichsen syndrome (WFS), also known as purpura fulminans, is a potentially lethal condition described as acute hemorrhagic necrosis of the adrenal glands. It is often caused by infection. Classically, Neisseriae meningitidis represents the main microorganism related A BALB/c mouse model of nonobstructive, ascending Proteus mirabilis pyelonephritis was characterized bacteriologically, histologically, and serologically from 3 to 28 days. Intravesicular administration of 2 X 10(8) P. mirabilis K7 resulted in the septic death of 9 (16%) of 57 mice by day 15. Among
Neonatal meningoencephalitis is a severe condition for the developing brain of a newborn. Radiologic findings of necrosis and liquefaction due to hemorrhagic meningoencephalitis may be confused with brain abcess. In this article, we report a neonate having liquefaction necrosis due to hemorrhagic
BACKGROUND
Necrotizing fasciitis is a rare soft tissue infection characterized by rapid progressive necrosis with relative sparing of underlying muscles. This case is reported to highlight the emergence of multidrug resistant microbes in recent days which limits the use of empiric antibiotic therapy
Background & aims: Proteus spp., Gram-negative facultative anaerobic bacilli, have recently been associated with Crohn's disease (CD) recurrence after intestinal resection. We investigated the genomic and functional role of Proteus as
Light brown, raised lesions were observed on the leaves of bell pepper (Capsicum annuum L.) plants throughout a commercial field in northwest Ohio in 1999. Bacterial streaming from the lesions was observed microscopically. Five representative, pale yellow colonies isolated on yeast dextrose
ABSTRACT The gram-positive tomato pathogen Clavibacter michiganensis subsp. michiganensis induced a local necrotic response on four-o'clock (Mirabilis jalapa) and tobacco (Nicotiana tabacum) plants. This necrosis response was characteristic of the hypersensitive response (HR). The cell-free culture
