    • ABSRACT - [ Total Page(s): 1 ]Salmonella and Shigella species isolated from human faecal samples were examined forBeta-lactamase production and resistance to some antibiotic agents. Age distribution of sources of resistant isolates showed thatShigella isolates from Youths (18 - 30 years) were more resistant to Ampicillin (66.67%) and Augmentin (33.33%) than isolates from Infants (6 months - 4 years) which showed percentage resistance of 3% to Ampicillin and 0% to Augmentin. Salmonella species isolated from Adults (31 – above) were more resistant to Augmentin (45%) and Ampicillin (40%), than isolates from Youths (18- ... Continue Reading

         

      CHAPTER ONE - [ Total Page(s): 1 ]CHAPTER ONEINTRODUCTION 1.1  INTRODUCTIONIn human medicine, the most important family of bacteria is Enterobacteriaceae, which includes genera and species that cause well-defined diseases, as well as nosocomial infections. The members of this family are Gram-negative, rod-shaped, non-spore-forming facultative anaerobes that ferment glucose and other sugars, reduce nitrate to nitrite, and produce catalase but seldom oxidase. Most Enterobacteriaceae are components of the gastrointestinal flora of humans and animals, although many are also widespread in the environment. Furthermo ... Continue Reading
