The Bacterial Foraging Optimization (BFO) is one of the metaheuristics algorithms that most widely used to solve optimization problems. The BFO is imitated from the behavior of the foraging bacteria group such as Ecoli. The main aim of algorithm is to eliminate those bacteria that have weak foraging methods and maintaining those bacteria that have strong foraging methods. In this extent, each b...
Most inverse classification algorithms address discrete attributes and can not deal with quantitative attributes. In order to overcome the disadvantage, the discretization algorithms are applied to the inverse classification algorithms, and the main idea is: firstly, a group of feature attributes are selected by using feature selection algorithm; then, the quantitative attributes are discretize...
مقدمه و هدف : عفونت کیسه زرده علت اصلی مرگ ومیر جوجه های گوشتی در هفته اول زندگی می باشد و در بسیاری از مرغداریهای کشور شایع است .این عفونت اغلب در نتیجه آلودگی پوسته تخم مرغ ایجاد می گردد ابتلا به عفونت کیسه زرده درایران حدود 10% و تلفات 5-10% می باشد هدف از این مطالعه تعیین فراوانی انتروباکتریاسه مسبب عفونت کیسه زرده در جوجه های گوشتی استان مازندران می باشد . مواد و روش کار : در این تحقیق از ...
objective: the aim of the this study was to investigate the prevalence of toxb, paa, lpf and iha adhesion genes in enteropathogenic escherichia coli (epec) isolates lacking in two important adhesion factors, the eaea and bfpa genes. methods: we examined a total of 70 serologically confirmed epec (eaea-, bfpa-) isolates. dna from the isolates was extracted by the phenol-chloroform method. toxb,...
Introduction & Objective: UTI is one of the most common bacterial infections and Ecoli is known as an important cause of UTIs. Since bacterial resistances of antibiotics are increasing, reliable methods of antimicrobial resistance detection are of paramount importance in treatment and management of UTIs. The objective of the present study is to compare and to evaluate the performance of disk ...
