The saliva of ticks contains anti-haemostatic, anti-inflammatory and immunomodulatory molecules that allow these parasites to obtain a blood meal from the host and help tick-borne pathogens to infect the vertebrate host more efficiently. This makes the salivary molecules attractive targets to control ticks and tick-borne pathogens. Although Ornithodoros moubata and O. erraticus are important ar...

Relapsing polychondritis is a rare multisystem disease. We describe the presentation and treatment of a patient with relapsing polychondritis and review the literature. This patient had involvement of the tracheobronchial tree requiring insertion of metallic stents.

Relapsing polychondritis is a rare inflammatory disorder of cartilage with well-established clinical features and imaging characteristics. Abnormal calcification and erosion of cartilaginous structures are the traditional radiographic findings. As with any disease, aberrancies of the expected clinical presentation may lead to a delayed (or missed) diagnosis. We discuss a rare case of relapsing ...

Ornithodoros (Alectorobius) capensis Neumann, an ectoparasite of seabirds found circumglobally in the tropics and subtropics, has become established along the southeastern seacoast of the United States. The tick has been found feeding primarily on brown pelicans, Pelecanus occidentalis, but also has been found on the laughing gull, Larus atricilla, and the American oystercatcher, Haematopus pal...
