Extension of an infection from the periorbital structures. This is the most common route. Infections which may breach the orbital septum and extend in this way include the paranasal sinuses, especially ethmoid sinusitis, the face, the globe, the lacrimal sac and dental infection via intermediary maxillary sinusitis. Extension of preseptal cellulitis, particularly in young children in whom the o...

BACKGROUND Burkholderia pseudomallei, the causative agent of melioidosis, is generally considered to be acquired via inhalation of dust or water droplets from the environment. In this study, we show that infection of the nasal mucosa is potentially an important portal of entry in melioidosis. METHODS After intranasal inoculation of mice, infection was monitored by bioluminescence imaging and ...

Cross-species transfers of pathogens (zoonoses) cause some of the most virulent diseases, including anthrax, hantavirus and Q fever. Zoonotic infections occur when a pathogen moves from its reservoir host species into a secondary host species. Similarly, commensal infections often have a primary reservoir location within their hosts' bodies from which they rarely cause disease symptoms, but com...

nosocomial infection and its heavy financial cost is a well recognized problem. a variety of sources of organisms involved in nosocomial infection have been identified in recent years. one potential route of bacterial infection is contamination. in order to assess the importance of food contamination, we carried out a survey of bacterial examination of food and the kitchen environment of 14 hos...
