The poultry area knew a remarkable development in the last decades within the Moroccan and worldwide territory, but it constitutes a serious problem of public health. The genus Campylobacter is the causative agent of the vast majority of cases of human Campylobacteriosis and food poisoning throughout of origin in the poultry products. This pathogenic is and ubiquitous bacteria in the environment and livestock sector primary poultry farm and able of colonizing in the tract digestive. In effect, these stocks cause diseases with strong impact constitute a danger in constant increase such as gastroenteritis and of complications extra-intestinal. Besides, these invasives bacterium introduce a resistance to certain antibiotics, but what is worrying, that they acquired a resistance to antibiotics prescribed for the treatment of the serious epidemics. This zoonose makes a major risk of public health. To diminish the impact of campylobacteriosis at Man, it requires a strategy of conflict against Campylobacter on the whole food production circuit of animal husbandry up to the end product, implicating good health practices and installation of a system of surveillance aiming at triggering off health alerts in time and in space.

Objective: Serological diagnosis of 48 suspected cases of Whooping Cough, received Medical Bacteriology Department at the National Institute of Hygiene in Rabat from four Moroccan provinces. The technique used is the ELISA. Results: From 48 suspected cases of Whooping Cough, 28 cases (58%) were positives, 10 cases (21%) were negatives and 10 cases (21%) were doubtful. Conclusion: Despite the effort of the Ministry of Health for immunization against pertussis immunization coverage which exceeds 90% of children, we see sporadic cases affecting some provinces that may be responsible for death.

Pertussis or whooping cough is a highly contagious infection of the respiratory tract caused by the bacterium albordtella pertussis. It’s a disease that could affects human at all his stages of life and the infection may be repeated several times, but gravity is reflected in babies given the complications that can lead to death. Over the last decades, the disease have increased although vaccines. And because of the decreased immunity against this disease among adults and adolescents, making them vulnerable, they become a source of infection for children who have not yet received the vaccine or have not completed the initial vaccination.

Bacteriological analysis is very important because it helps to identify the causal agent of infection: bacteria, parasites, fungi.
Our study has as purpose the statistical study of different types of analysis developed in the service for nine months ; the urine cytology examination (urinalysis), stool culture, cytology examination of the pus, the blood culture examination, examination of the cerebrospinal fluid (CSF), the bacteriological examination of secretions and ENT bronchopulmonary and ascites fluid and cytology examination of vaginal swab.
Based on the statistical study established and the results we determine the impact of the most common germs in different types of analyzes namely E.coli; klebsiellae and Staph.Aureus
