Bloodstream infection, peritonitis, and pneumonia caused by Pasteurella multocida in a patient with liver cirrhosis despite no animal contact: case report and literature review

Pasteurella multocida is an opportunistic pathogen. Previously reported infections associated with P. multocida have often been linked to contact with cats, dogs, and other animals. Cases of systemic multiple-site infections following P. multocida infection are rare. This case study presents a 49-year-old middle-aged man with post-hepatitis B cirrhosis and no history of animal contact. The patient was admitted with symptoms of fever accompanied by diarrhea, abdominal distension, and cough. Blood tests showed elevated levels of CRP, PCT, and IL-6, and blood culture revealed the growth of P. multocida. CT scans revealed a large amount of abdominal effusion, a small amount of pleural effusion, and pulmonary infection foci. The patient’s condition improved after successive administration of ceftriaxone and levofloxacin to fight the infection, and abdominal puncture and drainage. Multiple-site infections caused by P. multocida are rarely encountered in patients with liver cirrhosis but without animal contact, which could be regarded as serious conditions warranting careful attention in terms of clinical diagnosis and treatment

Origin–destination (OD) of the interprovincial floating population of China

<p>China’s large floating population catalyzes economic development, redistributes the population, and promotes social changes to the social structure, lifestyle patterns, and cultural values. The floating population is a unique group faced with numerous problems stemming from cultural and lifestyle differences. Understanding and visualizing the distributional characteristics and patterns of the floating population is crucial for developing effective social policies. In this study, the origin–destination (OD) map and its adjustment destination–origin (DO) map are used to represent the interprovincial floating population. The OD or DO map can be regarded as a two-level spatial treemap representing the floating population recorded by pairs of locations. In accordance with the different hierarchy of the two-level spatial treemap, the OD and DO are distinguished. The migration volume of the floating population data is represented by the OD and DO maps to find the population’s direction of movement, magnitude, and hot-spots. The migration indicators including migration effectiveness, migration preference indexes, and sex ratios are represented by the OD and DO maps, which assist in to reviewing and studying the deep patterns of floating population.</p
