ABSTRACT:
BACKGROUND:
On June, 22nd, 2013, Communicable Disease Control Center (CDCC) in Baghdad notified on an outbreak of Food Poisoning (FP) involving more than 100 persons attending a restaurant in Tikrit City, Salah Al Din province on21st, June.
OBJECTIVE:
to identify source, and causative agents of the outbreak.
PATIENTS AND METHODS:
A case seeries study conducted on accessed cases in Tikrit and Sala Al Din hospitals. Information on basic, clinical and food item consumed were collected using a questionnaire. Environmental assessment of the restaurant using a standardized checklist and bacteriology testing of food samples, patients’ stool specimens and different specimens from food handlers were conducted.
RESULTS:
A total of 214 persons who attended the restaurant sought medical care for acute gastroenteritis; 82 (38.3%) were admitted. Only 175 patients (including 11 affected food handlers) were accessed. Main symptoms were diarrhea (92.5%), nausea (87.5%), and vomiting (84.5%). Apart of one death, all other patients recovered completely. 32% of patients’ stool samples were positive for Salmonella typhimurium, and 30% of food specimens were positive for Staphylococcus aureus, and 10% for coliform bacteria; 13 food handlers were examined and specimens of blood, urine; and stool, and under the finger nail swabs, were negative. Health inspection of the restaurant revealed unhygienic food processing and poor personal hygiene of food handlers.
CONCLUSION:
Staphylococcus aureus and Salmonella typhimurium were the responsible pathogens. Contaminated food stuff and unhygenic foodhandlers practices were the source. Strengthening the role of health inspection, and upgrading local laboratory capacity were recommended.

ABSTRACT:
BACKGROUND:
Visceral Leishmaniasis is an endemic protozoal disease in Iraq. Recovery from this disease confers a solid and permanent immunity. Immunological assessment of our patients was carried out and the results showed that a significant increase in phagocytic index in patients with VL in comparison with control group.
AIM OF THE STUDY: Determining phagocytic index.
METHODS:
Blood samples were collected from 50 patients suffering from VL confirmed parasitologically by bone marrow smears, 40 blood samples from apparently healthy children and 50 blood samples from children in an endemic area (Al-Suwaira district).Their age was less than six years in all groups, and who were apparently healthy.
RESULTS:
The immunological assessment of our patients was carried out and the result showed that a significant increase in phagocytic index in patients with Visceral Leishmaniasis in comparison with control group (p<0.01). While the result of endemic control group by ELISA, IFAT and IC were used to test 50 serum samples from healthy children who lived in an endemic area. A total of 48 cases of them were found to be negative at least by one of the above tests, IC showed the lowest cross reactivity rate (4%).
CONCLUSION:
Phagocytic index was higher in patients with Visceral Leishmaniasis in comparison with control group.
