| This study was designed to isolate and identify the type of moulds and their percentage of distribution with pathological study of highly moulds isolated from (130)samples were included in this study with divided into (30)samples dried milk,(30).samples baby food ,(30)samples raw milk , (40) samples dairy products . The results revealed the percentage of infection according to total count of isolation in raw milk were 100 % dairy product 65 %. The most common fungi isolated from raw milk were Asp.niger of 16.2 % Asp. fumigatus of 15 % Asp.flavus of 13.7 % Pencillium spp. 12.5 % . From dairy products were isolated with percentage of Asp. Fumigatus 34.9% Geotrichum spp . of 23 % ,Asp. nager of 11.5 % . Pathological study was carried out to investigate the clinical signs with grossly and Histopathological changes inoculated with most pathogenic moulds Asp. fumigatus (30)male white swiss mice were used in this study and divided into four groups . The first group were injected I/P with 0.2 ml of Asp. fumigatus containing 1X105 spores / ml , 4th group (control)given orally 0.2 ml of PBs.Two mice from each treated groups and one from each control group were scarified on week (1,2,3,4) .the clinical manifestation of the 1st group were at 2nd week showed dyspnea .Mould isolated from blood and internal organs at third week , with no isolation from 3rd group.
