The present study was carried out to study the effect of extracts from some medical plants on microorganisms isolated from local soft cheese and find out if there is any possibility for eliminating these microorganisms. Local soft cheese samples are taken from local sellers in AL-Diwaniya city markets. Samples were collected, (20) specimens monthly, from November (2011) until June (2012), the total number of samples was (160). All kinds of bacteria, Molds and yeasts in these samples were detected. The following microorganisms were isolated from the cheese samples studies: coliform bacteria, fecal coliform bacteria, streptococci, fecal streptococci, salmonella, staphylococci, psychrotrophic bacteria, thermophilic bacteria, proteolytic bacteria, lipolytic bacteria, spore forming bacteria, molds and yeasts. Moreover, ecological conditions also proved influential on the number of microorganisms beings in the cheese samples studied regardless of their sources , there number in the summer months was much greater than in the winter months. Some medical plants extracts were used to detect if they have any effect on group of the isolated microorganisms included: Staphylococcus aureus ; Escherichia coli ; Streptococcus faecalis ; Bacillus sp. ; Proteus vulgaris ; Pseudomonas flourescens ; Klebsieella pneumonia ; Salmonella spp. ; Aspergillus niger and Penicillium sp. The ethanol and aquatic extracts from six medical plants were used in the study, these plants include: Trigonella foenum-graceum L., Foeniculum vulgare mill , Rosa damascena mill, Pimpinella anisum L., Mentha piperita L. and Jasminum, grandiflorum L. All the aforementioned plants had prohibiting effect on 5 kinds of the microorganisms studied with different degrees of prohibition . The ethanol extract proved more powerful than aquatic extract . It was also found out that prohibiting effect of the extract decreases with the decrease in it's concentration and differs according to the kind of bacteria and the kind of plant.
