extensively drug-resistant tuberculosis (xdr-tb) is a new challenge for tuberculosis control programs. lack of effective drugs and high rate of failure in treatment and mortality is a major threat for public health. treatment of this serious infection needs well-designed individualized dosage regimen and powerful national tb program. in this review we will describe the xdr-tb definition and its...

A comprehensive invasive pneumococcal disease (IPD) laboratory surveillance program was carried out in Australia in 2003. This program provided data on the prevalence of pneumococcal serotypes and antimicrobial resistance. There were 1,995 isolates tested with 34 per cent (683) from children aged less than five years and 27 per cent (535) from the elderly aged more than 65 years. One thousand e...

Streptococcus suis serotype 2 (S. suis 2) is a zoonotic pathogen that exhibits high-level resistance and multi-drug resistance to classic antibiotics and causes serious human casualties and heavy economic losses in the swine industry worldwide. Therefore, alternative therapies or novel antibacterial agents need to be developed to combat this pathogen. A novel endolysin derived from the S. suis ...

objectives in this study, we aimed to determine the prevalence of the species of campylobacter. jejuni in zahedan, a major city in southeastern iran. patients and methods fecal samples from 164 patients with acute diarrhea from zahedan hospitals were collected from 2011 to 2013. then the samples were streaked onto a campylobacter selective agar containing supplement and 7% defibrinated sheep bl...

the emergence of multi-drug resistant strains of pseudomonas aeruginosa has complicated treatment decision and may lead to treatment failures. in this study, we describe the trends of drug-resistant p. aeruginosa isolated in blood cultures from patients detected in a tertiary teaching hospital and evaluated the prevalence of resistance to amikacin, ampicillin, carbeni- cillin, cefixime, cefotax...

pseudomonas aeruginosa is one of the most important pathogens that causes nosocomial infections and shows high level of antibiotic resistance. integrons are one of the transposable elements in bacteria and their role in antibiotic resistance has been well demonstrated. the aim of this study was a molecular characterization of the integron genes and the determination of the resistance or sensiti...

Pneumococcal infections are a major cause of morbidity and mortality in developing countries. The introduction of pneumococcal conjugate vaccines (PCVs) has dramatically reduced the incidence of pneumococcal diseases. PCVs are not currently being used in Algeria. We conducted a prospective study from 2005 to 2012 in Algeria to determine antimicrobial drug resistance and serotype distribution of...

conclusions the results of this study indicated that a decrease in oprd gene expression is an important mechanism of resistance in carbapenem resistant pseudomonas aeruginosa isolated from severe burn patients with secondary infection. results our study showed that 94.2% of the isolates were resistant to imipenem, 99.5% to meropenem, and all were resistant to ertapenem. the oprd gene expression...

background: campylobacter infections may lead to serious conditions, including septicemia or other invasive forms of the disease, which require rapid and accurate laboratory diagnosis and subsequently appropriate antimicrobial therapy. the aim of this study was to compare the species distribution and antimicrobial susceptibility pattern of campylobacter spp. strains isolated from patients and f...
