staphylococcus spp., is a common bacteria in cattle mastitis. detection of the low number of bacteria requires a sensitive method. we used multiplex polymerase chain reaction (m-pcr) assay to detect the genes encoding sea, seb, sec toxins, that are specific in s. aureus bacteria. the gene of 23s rrna that is conserved in all staphylococcus spp., also was used. due to the stiffness and low effec...
Microbiological methods such as Gram staining and culture of low respiratory tract secretions are necessary to detect the real bacterial pathogens that cause lower respiratory tract infections (LRTI). In many cases, Gram stain analysis may be unreliable to determine the cause of LRTI, and bacterial cultures provide adequate information. However, we herein report two cases of lower respiratory t...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
abstract the problems caused by the traditional system of criminal justice (which are based on remuneration and rehabilitation) such as, lack of attention to victim’s rights and position and society, underlie the emergence of restorative justice which had the victim-centered perspective, with respect to the role of the offender and participation of civil society. meanwhile, criminal mediation ...
OBJECTIVE Urine is the most frequent specimen received for culture/sensitivity by clinical laboratories. The microbiological performance of HiCrome UTI agar medium was compared with Blood agar and MacConkey agar for isolation and presumptive identification of bacteria from urine culture. METHODS A total of 443 consecutively collected midstream and/or catheter-catch urine samples from patients...
Cultures of Helicobacter pylori obtained from the American Type Culture Collection (strain 43504) were grown as isolated colonies or lawns on blood agar plates and in broth culture with constant shaking. Examination of bacterial growth with Gram-stained fixed preparation and differential interference contrast microscopy on wet preparations revealed that bacteria grown on blood agar plates had a...
Background and Aim: Bacteria are one of the causes of nail infections. Although nail infections are not always associated with a major health problem, their treatment, particularly in immunosuppressed patients could be chalenging. This study was conducted to investigate the prevalence of bacterial agents in patients with dystrophic nails referred to mycology laboratory of Razi Hospital, Tehran...
Leukemia is a systemic disease in which the normal mechanisms for producing blood elements impairs. Leukemia, malignant clonal growth of hematopoietic cells, is resulted from a malignant precursor cells. ALL is the most common cancer among children. These patients are prone to get bacterial infections. Serratia marcescens is one of the most common bacterial causes of nosocomial infections and e...
Background and purpose: Ëar infection in one of the common problem of ËNT specialists and the general physicians. Ëxternal otitis is a painfull inflammation of external auditory metus and earlob. Ôtitis can be of infectious and noninfectious type, or both. The infection is caused by bacteria and fungi. Prevalence of external otitis is quite more in summer than in winter season. Due to climati...
The aim of this study was to compare invasive and non-invasive strains of Shigella flexneri isolated from Tehran by a 120 kDa protein band by SDS-PAGE, electron microscopy of cell culture and Congo red dye methods. Methods: S. flexneri strains were isolated by standard bacterial methods from fecal specimens of children attending to the 3 children’s hospitals. Phenotype analysis for screening v...
