Abstract:
A questionnaire style survey on Pasteurella multocida infection was conducted at on 528 laboratories of hospitals. The questionnaire included the detection of Pasteurella multocida from sputum, the age distribution, underlying disease etc. of the patients. In Japan, infectious diseases caused by Pasteurella multocida were found in 179 cases in 67 (26.0%) of the 258 hospitals. The incidence of the infections tends to increase, 18 cases in 1989, 25 cases in 1990, 18 cases in 1991 (Jan.-Jul.). These 179 cases were broken down into 44 males (from 1 year old to 85 years old, mean 58.9 years old), 45 females (from 18 years old to 85 years old, mean 60.2 years old), and 90 patients whose sex was unknown. Underlying diseases were recognized in 72 cases. Diseases related to the respiratory organ were 61 (84.7%) cases. The cases of hemo-sputum had to be differentiated from malignant tumors Recurrent Pasteuralla multocida infections were recognized in 4 males and 4 females. And the 4 cases had been handling animals. There were only 26 cases who had contact with animals, the others were unknown. This result suggested that contact with animals may cause these infections. Recently, the detection of Pasteurella multocida from the sputum tends to increase. The elderly patient with chronic pulmonary disease, who is handling animals must be educated on hygiene and zoonosis.
Insights
Pasteurella multocida infections, often from respiratory sources, are increasing in Japan, particularly among the elderly. Handling animals may increase risk, highlighting the need for hygiene education.
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Context:
- Pasteurella multocida is a bacterium that can cause infections in humans.
- Surveys in Japanese hospitals reveal an increasing incidence of Pasteurella multocida infections.
Purpose:
- To investigate the prevalence and characteristics of Pasteurella multocida infections detected from sputum in Japanese hospitals.
- To identify risk factors and patient demographics associated with these infections.
Summary:
- A survey of 528 hospital laboratories in Japan identified 179 cases of Pasteurella multocida infections.
- Infections were more common in elderly patients with underlying respiratory diseases.
- Contact with animals was suggested as a potential transmission route, though often unknown.
Impact:
- Highlights the growing public health concern of Pasteurella multocida infections, especially in vulnerable populations.
- Emphasizes the need for increased awareness and preventative measures, including hygiene education for individuals handling animals.
- Suggests further research into zoonotic transmission and diagnostic improvements.
