Abstract:
The current study has been done to determined pathogenic bacteria that associated with appendicitis .This study includes ninety samples of removal appendix taken form patients who cleared diagnosed as appendicitis infection by specialised doctors in general Basrah hospital and Al - Sadir teaching hospital for the period between September - 2013 and June - 2014.Distribution of appendicitis appear in all age groups, 10 - 20 year and 20 - 30 year were the most infected, as well as the infection appear in both gender, but rate of infection in male was relatively higher than female 68(59%), 47(41%) respectively. The ratio of the city's population has overcome the rural population 96(83.5%),19 (16.5%) respectively. The percentage of samples that gave positive culture was 80( 88.9%), while 10 (11.1%) of these samples negative culture. The study reveals 15 different bacterial isolation, the most common bacteria was Escherichia coli 80(44.9%) while other species was appears in less percentage Shigella dysenteria 14(7.9%), Salmonella enterica typhi 10( 6.5 %), Pseudomonas aeruginosa 8( 5.6 %) , Klebseilla Pneumonia 6(4.3%) , Klebseilla oxytoca 3(1.7%), Morganella morganai 7 ( 9.3 %) Neisseria spp. 6 ( 9.5%) , Enterobacter cloaca 4 ( 2.2 %) ,Serreatia spp. 3 )7.1 %(, Citrobacter ferundii 2 (7.7%) Proteus vulgaris 7) 6.5 %( Staphylococcus spp. 14(1.3%), Streptococcus spp. 72(5.1 %) and Bacillus subtilis 8)5.6 %(. Laboratory diagnosis for blood samples included estimated of total WBCs and found that (31%) of patients have natural WBCs values while the other patients have high values.Antibiotic sensitivity test to E.coli isolates towards 20 antibiotics because she is the most common bacteria showed that all isolates were resisted for most antibiotics which used in test especially for β - lactam group, and the isolates of E.coli were multi resistance for antibiotics.Identified minimum inhibitory concentrations MIC for some antibiotics The results showed that E.coli bacterial isolates's 30 isolation have shown resistance to anti AMO as MIC values ranged from 128 - 1024 Mcgm / ml while the MIC for Anti AMP values between 4 - 128 Mcgm / ml, As for antibiotics and Cefixim , Ceftriaxone, Cefotaxime, and it was her MIC values ranging between (1 - 128) Mcgm / ml Plasmid profile of E.coli isolates investigated to study the correlation between plasmid profile and antibiotic resisitant marker and results from agarose gel electrophoresis revealed that all E.coli isolates contain one plasmid band.This study includes the detection of some genes that encode to beta - lactamase enzymes in E.coli which were responsible about multi antibiotic resistanc and these genes loaded on plasmid DNA for ten isolaes and found that 5(50%) from isolates have blaTEM gene and 5 )40%( have blaCTX gene and 1(10%) have blaSHV gene. This study also considered note the general appearance of appendix samples , some of them are enlarged and surrounded by vesicles, some with fibrous walls and ulcerated with mixed colors, then examined the histological changes it, the study showed changes in histological structure of the excess was extensively congestion of blood vessels, veins in serosa and subserosal layers and increased the amount of diffuse lymphoid tissue in the layers of the appendix walls.
