Bakteri Shigella dysenteriae merupakan penyebab disentri yang bakteri negatif Gram dengan bentuk batang pendek atau basil tunggal. ini bersifat anaerob fakultatif dan memfermentasi glukosa serta tidak laktosa. Masalah pencernaan karena infeksi masih tinggi di Indonesia menyebabkan tingginya intensitas penggunaan antibiotik memicu berbagai permasalahan terutama resistensi. Termasuk telah menunju...

In this study, the antimicrobial susceptibilities and presence of plasmids in 7 probiotics strains which had been isolated from the fermented milk were determined. Resistance to 8 commonly used antibiotics $lactans (penicillin, ampicilin), gram positive spectrum (vanomycin), broad spectrum (rifampin, trimethoprim) and aminogycosides (kanamycin, streptomycin, and bacitracin) was assessed by disk...

Kvržične bakterije u simbioznim zajednicama s mahunarkama omogućuju značajan unos biološki vezanog dušika tlo. Veliku važnost ima odabir sojeva koji su otporni na stresne uvjete tlu. Danas se sve više susrećemo ekstremnim vremenskim uvjetima te je od iznimne važnosti selekcija visoko učinkovitih kvržičnih bakterija (rizobija) kako bi predsjetvena bakterizacija sjemena mahunarki bila uspješna. C...

BACKGROUND Typhoid fever is a global health problem. The World Health Organization (WHO) estimates that the current annual global burden of typhoid is approximately 22 million new cases, 5% of which are fatal. METHODOLOGY To assess the trends in antibiotic resistance in 100 Salmonella enterica serovar Typhi strains were isolated from the blood of patients in Nairobi, Kenya, from 2004 to 2006....

Previous studies have shown that pretreatment with sub-lethal kanamycin to E. coli B23 cells provided protection against subsequent exposure to lethal amounts of the same antibiotic. It has also been shown that exposure to sub-inhibitory levels of certain antibiotic can induce cross resistance by promoting the development of low-level resistance to other functional and structural unrelated anti...

As a result of the ever increasing problem of multiresistant bacteria, we instituted a surveillance program with the aim of identifying the basic molecular properties of ESBL in our environment. About 197 isolates of Escherichia coli and Klebsiella pneumoniae were selected and tested for ESBL production and antimicrobial susceptibility. Plasmid profiles were determined and curing ability was te...

The aim of my investigations is novel applications of modified laser interferometry method in microbiological, biophysical and biochemical analysis. The measurement system consists of Mach-Zehnder interferometer with a He-Ne laser, a TV-CCD camera and a computer with a system for the acquisition and processing of interference images. The method is based on the phenomenon of diffusion process an...

This study was conducted to determine the epidemiologic pattern's of shigellosis in children in Qazvin children hospital during 137 5-7 6. The study of 166 children with diagnosis of shigellosis (shigella was grown in s/c) during 2 years showed that: prevalence of shigellosis were high in male and summer, peak age of shigellosis was in 1-4 years (65/7%).Most common symptoms were fever (91.6%), ...
