Seventy five random samples were collected (25 raw milk, 50 local different made soft cheeses) from different supermarkets in Tripoli- Libya. The Objectives of this study were: (i)- to clear the incidence rate and count of coliforms as an indicator microorganisms for fecal contamination in raw milk and locally made soft cheese samples manufactured by traditional methods and (ii)- to make comparison between the most famous two conventional methods used for counting of such group of microorganisms. Coliforms were recovered from all the raw milk samples using the two methods (most probable number using liquid lauryl sulphate broth and sold plating method using violet red bile agar). The mean count for the former media was 28x106 while for the later one was 15x106 cfu/ml. For cheese samples (locally made Ricotta and Maasora), positive samples were 78% (39 samples) using MPN method, while 76% (38 samples) using sold plating media VRBA. The mean coliform count for positive samples using MPN was 18x107 cfu/g, while for VRBA plates the mean count for positive samples was 21x106 cfu/g. all counts were higher using MPN than VRBA for the same sample in both raw milk and cheese samples, although, clear difference in count between the two methods was recorded in cheese than that in raw milk, conditions that may affect the count in both raw milk and cheese were discussed.

Background: Pseudomonas aeruginosa is one of the most invasive organism that causes severe tissue damage in diabetic foot ulcers. A major problem in P. aeruginosa infection because of that it is commonly exhibits a high degree of resistance to antimicrobial agents .To improve appropriate antimicrobial therapy and reduce the incidence of antibiotics resistant bacteria, information on the antibiotic susceptibility to this bacterium is urgently needed. Therefore, the aim of this study was to isolate and determinate the antimicrobial susceptibility of the P. aeruginosa in diabetic foot ulcers patients. Methods: This study was carried out over the period between June 2014 to April 2015 at Tripoli Medical Center. A total of 120 bacterial isolates were cultured onto bacteriological media such as nutrient agar, MacConkey agar and blood agar. Identification of retrieved bacterial isolates was done using standard diagnostic microbiological laboratory methods and antibiogram was determined by VITEK ® 2 compact automated system. Results: Twenty one strains of P. aeruginosa from 120 diabetic foot ulcers were detected. P. aeruginosa isolates exhibited multidrug resistance to Ampicillin, Augmenting, Cefuroxime, Cefoxitin, Cefazolin, Ceftriaxone, Trimethoprim/sulfamethzole, Piperacillin. However, all isolates of P. aeruginosa were 100 % sensitive to Imipenem. Conclusion: P. aeruginosa infections of diabetic foot ulcers patients have multi-drug resistant. Imipenem is the empirical antibiotic of the choice. Key words: Pseudomonas aeruginosa, diabetic foot ulcer, antibiotics resistance arabic 17 English 114

Adhesion and colonization of high (2 × 108 CFU) and low doses (2 × 102 CFU) ofSalmonella enteritidis (phage type 4) was determined in the ceca collected 6 h-4 weeks after inoculation (pi), of 1-d-old White Plymouth Rock orally-inoculated chickens.S. enteritidis was associated with the epithelial surface of the villi in the low-dose group 18 h-7 d pi, the penetration in the cecal lamina propria was observed on day 1 and 10 pi. In the high-dose group, adhesion and colonization was observed in all birds killed 6 h-14 d pi; penetration of the bacteria into the cecal lamina propria was seen 1–21 d pi. Large numbers of macrophage-like cells containingS. enteritidis were observed in the cecal lamina propria on days 3–21 pi. Colonization and migration byS. enteritidis in the intestinal tract of chickens was shown to be dose dependent.
