Pneumonia is defined as inflammation of the pulmonary parenchyma and most commonly encountered respiratory problems in small ruminants throughout the world (Ackermann and Brogden, 2000). In goat herds, pneumonia increases production costs associated with expensive treatments which cause economic burden to small and marginal farmers. Though pneumonia is generally fatal in kids, infections and de...

Pertussis was a major childhood disease in parts of West Germany in 1990. Before a prospective household contact trial into the efficacy of an acellular pertussis vaccine was undertaken, the epidemiology of the disease was studied in one area. This study showed that pertussis had an annual incidence of 4%-6% in the first 6 years of life. During the trial, a total of 1223 pertussis cases were di...

Incidence of whooping cough, an infection caused by Bordetella pertussis and Bordetella parapertussis, has been on the rise since the 1980s in many countries. Immunological interactions, such as immune boosting and cross-immunity between pathogens, have been hypothesised to be important drivers of epidemiological dynamics. We present a two-pathogen model of transmission which examines how immun...

Pertactin (PRN) is an autotransporter protein produced by all members of the Bordetella bronchiseptica cluster, which includes B. pertussis, B. parapertussis, and B. bronchiseptica. It is a primary component of acellular pertussis vaccines, and anti-PRN antibody titers correlate with protection. In vitro studies have suggested that PRN functions as an adhesin and that an RGD motif located in th...
