abstract sclerogenic fungal pathogens, are among the most important diseases of rice plant. sheath blight caused by rhizoctonia solani is one of the economically important diseases that attack a wide range of hosts. stem rot (magnaporthe salvinii) has also been found with different severity in most fields of guilan province. to determine sclerogenic fungal pathogens of rice plant, 141 isolates ...

introduction: the efficiency of routine scaling and root planning is negatively influenced by the tooth anatomy and residual bacteria all possibly affecting the treatment outcomes in future. the present study compared the microbiologic effectiveness of the photodynamic therapy (pdt) as an adjunctive treatment modality for nonsurgical treatment in chronic periodontitis. methods: in this randomiz...

The triphosphate tunnel metalloenzyme (TTM) superfamily represents a group of enzymes that is characterized by their ability to hydrolyze a range of tripolyphosphate substrates. Arabidopsis (Arabidopsis thaliana) encodes three TTM genes, AtTTM1, AtTTM2, and AtTTM3. Although AtTTM3 has previously been reported to have tripolyphosphatase activity, recombinantly expressed AtTTM2 unexpectedly exhib...

Subpopulations of peripheral leukocytes and cytokine mRNA expression levels were evaluated in scouring and healthy Holstein calves (age 10 ± 5 days; n=42) treated with a probiotic consisting of Lactobacillus plantarum, Enterococcus faecium and Clostridium butyricum. The calves were assigned to the scouring or healthy group and then subdivided into pathogen-positive treated (n=8), pathogen-posit...

BACKGROUND Monomicrobial necrotizing fasciitis is rapidly progressive and life-threatening. This study was undertaken to ascertain whether the clinical presentation and outcome for patients with this disease differ for those infected with a gram-positive as compared to gram-negative pathogen. METHODS Forty-six patients with monomicrobial necrotizing fasciitis were examined retrospectively fro...

Pseudomonas stutzeri is a Gram-negative bacterium that has been accounted for as causative specialist of certain diseases. It cause pneumonia, meningitis, visual disease, osteomyelitis and joint Thus, this species could be considered an opportunistic but rare pathogen. In addition, possess extensive variety resistance mechanisms against diverse group antibiotics

Arcobacter cryaerophilus group 1B, a gram-negative, curved or helical bacillus primarily known as a bovine and porcine pathogen, was isolated from the blood of a uremic patient with hematogenous pneumonia. The patient was treated successfully with ceftizoxime and tobramycin.

Capnocytophaga organisms are capnophilic, gram-negative bacilli that have been associated with infections deriving from the flora of the oropharynx. We report a case of inguinal adenitis caused by Capnocytophaga species that probably represents sexual transmission of the pathogen.

Aerococcus urinae is a pathogen that rarely causes severe or fatal infections. We describe four cases of severe A. urinae bloodstream infections. All patients had underlying urologic conditions. Urine cultures, however, were negative.
