| The aim of this study is discover about pathogenic microorganism which are growth on tomato fruit that provide in the local market and consumptive unknown there dangerous . This is include four cities in Diwaniya governorate (The Center, Alshamiya, Afak, Alhamza), the different which the percent of frequency fungi geneses (Penicillium sp., Geotricum candidum, Fusarium sp., Rhizopus sp., Rhizoctonia sp., Aspergillius sp., Alternaria sp., Pythium sp. Stemphylium sp., Stigmella sp., Microsporium sp., Sirosporium sp., Ulocladium sp.)and that isolated of tomato fruit and that appeared is(Geotricum candidum ( of dominance the percent frequency (100, 100,30,50 )% from between isolated of fungi from tomato fruit in cities , and the study include discover at bacteria which it on the tomato fruit and caused it decay at the same of cities . it used the biochemical testes in diagnosis process. The number of bacteria genus is isolation in cities which such as (Streptococcus faecium, Streptococcus lactis, Shigella sp., Pseudomonas sp., Salmonella sp., Srvia marsence, Bacillius subtilus, E. coli , Staphylococcus aureas) and the found of the different percent in bacteria genus which is Shigella sp of the genus dominance that the frequency of the percent (95, 0 ,100, 83 ) % . |
