One hunderd f random frozen chicken carcasses were purchased frm supermarkets in cair governrate fr bacteriolgical examination standard methds were used t determine anaerobic and aerobic micrrganisms. Samples were classified into two group (50 f each then examined for aerobic bacteria Isolates from group I were C. sporogenes after three months of freezing with a reduction 985 while the mean value of enterobacteriaceae.

Tw hunderd and fifty random samples were collected from 125 sheep carcasses from both surfaces of shoulder regin at sharkia traditinal abattoir cover the whole day of work . the recorded counts of microrganisms were attributed to existence of prteolytic and lipolyic acetic acid were shown to be consistently effective methods for reducing total aerobic counts , total proteolytic conts , total lipolytic counts and staph aureus counts . the mean count of these
while using saponine 15 show reduction in total bacterial count equal to that occur by water wash

In 2005, clinical signs of skin lesion on cattle referring to lumpy skin disease appear in many cattle farm in Sharkia Governorate, the observed signs were pyrexia, anorexia, dysagalactia, emaciation, enlarged lymph nodes, edema of skin and nodules on the skin mostly appear as circumscribed, flat tapped, firm nodules which may cover the whole of the animal body. The morbidity rate was 60% and the mortality rate was 5%. The viral was identified by neutralization with specific antiserum. The hematological and biochemical changes as well as the necropsy and histopathological findings were reported and discussed. The clinical signs, virological and pathological investigation will quarantine an diagnosis of the disease

Atotal of fifty random samples of plain yoghurt were collected from from dairy shops and supermarkets in kafr El- Shikh city produced by small and large modern factories (25 each ) . All the samples were directly transferred to the laboratory under aseptic condition and subjected to the microbiological ,

the present investigation was carried out for studing Sarcocystis sp. in cattle at Dakahlia province. A survey conducted from june 2005 till May 2006 , 446 out of 600 ( 74.33% ) muscular tissues were collected from slaughtered cattle at Dakahlia abattoir containing numerous white spindle -shaped bodies .the esophageal muscles were more infected than the other muscles .the infection was high in summer followed by autumn to be 93.33% and 92% followed by spring ( 80% ) and the winter ( 32% ) .it was found that the old cattle were more susceptible the to infection than younger ones

this study was carried out for studing the scaly leg disease affecting turkeys where two hundred and five turkeys were randomly collected from different localities in Dakahlia province during aperiod extended fron April 2005 till March the clinical examination revealed that the affected birds were anaemic with scaly hyperkeratosis on the feet and legs pruritis itching weight loss and dyspoea in this study two typs of mite were identified knemidocoptes mutans and petopagus strictus the results indicated in spring and summer 18.46% and 11.27% respectively followed by autumn and winter ( 10% ) and ( 7.01%) respectively Also it was noticed that ivermection 1% at dose of 0.2mg/kg B.w some blood parameters were made before and after treatment .

Atotal 120 fish samles of Tilapia nilotica and Mugil cephalus (60of each) were collected randomly from three private fish farms at El- Reyad sidi- Salem and El- Hamoul districts .

This study was carried out on one hundred and fifty men high risk in direct contact with these sheep from different localties in Sharkia Governorate These cases were subjected to serological tests for diagnosis of the disease . These screening test were Rose Bengal test (RBT) and Buffered plate aggluination (BPAT) seropositive samples were confirmed by Rivanol test (Ri-T) and tube agglutination test . The results of examined revealed cases that thirty sheep (30%) and seven persons (14%) were seropositive . Five serum samples were obtained from seropositive and another five serum samples of seronegative animals . The procedures were repeated in seropositive and seronegative human They were subjected to biochemical examination Biochemical studies revealed a signifcant ivcrease in sAST sALT , sAP and serum globulin meanwhile a significant decreasein total protein , albumin , calcium and inorganic phosphorous of affected sheep &men compared with the healthy ones One blood sample was taken on sodium salt of EDTA from each case of the above examined cases They were subjected to hematological study The affected cases both animals and human revealed normocytic normochromic anemia associated with higher ESR, leukocytosis neutrophilia and lymphopenia It could be concluded that brucellosis led to disturbance of general health condition of the host , so careful attention must be paid for early diagnosis of this zoontic disease followed by eradication of seroreactor sheep ;vaccination of non reactors and a therapeuticplan for the disease from workers.

A total of one hundred random fish samples were collected from various sites in Alexandria province .The samples were represented by four species of fish . Two species from brackish water fish .

Chicken stock cube samples were randomly collected from supermarkets for evaluation their microbial and chemical quality . Samples represent two different commercial for trade brand (A,B) The mean values of APC, B. cereus, coliforms and Staph. aureus for stock samples brand (A) and brand (B) were 2x10 . The results were discussed and recommendations to improving the quality of the chicken stock were given .
