Ice cream as a possible method of spreading antimicrobial resistant pathogenic bacteria

  1. 1. Ice Cream a Possible Method of Spreading Antibiotic-Resistant Pathogenic Bacteria in the Community K.S. Ghenghesh1, N. El-Sharef2,  Y.S. Abognah2, S.O.Gnan2, A. Rahouma1 Faculty of Medicine1 and Faculty of Agriculture2, Tripoli University, Tripoli-Libya
  2. 2. OBJECTIVES
  3. 3. • To determine what are the pathogenic bacteria found in ice cream sold in Tripoli? • To determine the resistance profiles of the isolated pathogenic bacteria to antimicrobial agents.
  4. 4. METHODS
  5. 5. • 160 ice cream samples were collected from different manufactures in Tripoli. • Standard bacteriological techniques were used to isolate the organisms. • The Disc diffusion method was used to determine their susceptibility to antibiotics.
  6. 6. RESULTS
  7. 7. Pathogenic bacteria isolated from 160 ice .cream samples sold in Tripoli-Libya Organism No. (%) positive Escherichia coli 10 (6) Salmonella 8 (5) Aeromonas 30 (19) Staphylococcus aureus 60 (38) Listeria monocytogenes 7 (4)
  8. 8. Resistance rates of Gram-negative pathogenic bacteria from ice cream in Tripoli to antibiotics No. (%) resistant Antibiotic E. coli Salmonella Aeromonas Total (n=10) (n=8) (n=30) (n=48) -----------------------------------------------------------------------------------------------Ampicillin 6(60) 6(75) 28(93) 40(83) Amoxicillin5(50) 4(50) 10(33) 19(40) clavulanic acid Cefuroxime 0 3(38) 9(30) 12(25) Ciprofloxacin 0 0 0 0 Gentamicin 0 0 0 0 Tetracycline 1(10) 2(25) 6(20) 9(19) Trimethoprim0 0 6(20) 6(12.5) sulphamethoxazole
  9. 9. Resistance rates of Gram-positive pathogenic bacteria from ice cream in Tripoli to antibiotics No. (%) resistant Antibiotic S. aurues L. monocytogenes Total (n=60) (n=7) (n=67) -------------------------------------------------------------------------------------------------Ampicillin 60(100) 0 60(90) Amoxicillin30(50) 0 30(45) clavulanic acid Cefuroxime 34(57) NT Ciprofloxacin 4(7) NT Gentamicin 8(14) 0 8(12) Tetracycline 13(22) 3(43) 16(24) Trimethoprim13(22) 4(57) 17(25) sulphamethoxazole Methicillin 0 NT Vancomycin 0 NT
  10. 10. CONCLUSINS
  11. 11. • Antibiotic-resistant pathogenic bacteria is not uncommon in ice cream sold in Tripoli. • Ice cream should be considered as a possible method of spreading antibioticresistant organisms in the community.
