Strains of extended-spectrum beta-lactamase-producing Klebsiella pneumoniae (ESBL-KP) have emerged worldwide. Concomitant ciprofloxacin resistance with ESBL production in K. pneumoniae isolates would severely restrict treatment options. Among 39 (18.5%) of 211 ESBL-KP isolates resistant to ciprofloxacin (MIC, >/=4 micro g/ml), 37 (95%) were high level resistant (MIC, >/=16 micro g/ml). These is...

OBJECTIVE To estimate the costs of diagnosis and treatment of diabetes in Tanzania. DESIGN Costs estimated from the reported and recorded experience of patients with newly presenting diabetes in 1989-90 and of diabetic patients first seen in 1981-2. SETTING Muhimbili Medical Centre, Dar es Salaam. SUBJECTS 464 patients (315 men and 149 women). 262 patients diagnosed during 1 September 198...

introduction and aims: acinetobacter baumannii in recent decay has become an increasing concern in hospitals for its ability to acquire antibiotic resistance determinants rapidly and becoming resistant to almost all of the antibiotic classes. borage (echium amoenum  fisch. et mey), is a wild annual plant of boraginaceae family, grows in northern mountains of iran and has largely been used by ir...

The genetic nature of resistance and its epidemiologic effects on two Meloidogyne incognita populations were assessed in the F hybrid tomato cv. Small Fry. The progeny of a Small Fry x Small Fry cross segregated in a 3:1 resistant:susceptible ratio, indicating the presence of a single, completely dominant resistance gene (LMiR) in Small Fry. In a subsequent experiment, infection frequency and t...

24 The emergence of drug-resistant herpesviruses represents a significant problem in clinical practice, primarily 25 in immunocompromised patients. Furthermore, effective antiviral therapy against gammaherpesvirus26 associated diseases is lacking. Here, we present two thiothymidine derivatives, KAY-2-41 and KAH-39-149, 27 with different spectrum of antiviral activity compared to reference anti-...

the aim study antibacterial effects of silver nanoparticles against resistant strains of e.coli bacteria.12 strains of e. coli strains arising urinary infection were isolated from hospitalized patient in zabolhospitals. minimum inhibitory concentration of winter cherry were determined by dilution method in various concentration on bacteria. the highest mic values was found to be 100ppm against ...

Two cell lines, M10-45-2 and L-41, were studied, each of which possessed specific resistance either to poliovirus or to coxsackievirus. Infection of M10-45-2 cells with poliovirus ribonucleic acid (RNA) and L-41 cells with infectious coxsackievirus RNA was accompanied by production of complete viruses in each of the resistant cell lines. During incubation of the cells with the virus to which th...

This paper is the second one in a series of papers about operations in motivic cohomology. Here we show that in the context of smooth schemes over a field of characteristic zero all the bi-stable operations can be obtained in the usual way from the motivic reduced powers and the Bockstein homomorphism (Theorem 4.46). This paper has been delayed for many years because I tried to find a way to ex...
