Silicosis (previously miner's phthisis, grinder's asthma, potter's rot and other occupation-related names) is a form of occupational lung disease caused by inhalation of crystalline silica dust, and is marked by inflammation and scarring in the form of nodular lesions in the upper lobes of the lungs.
Serratia marcescens is another facultative pathogen of insects, causing septicemia. The non-spore-forming bacterium, Melissococcus pluton, is the causal agent of European foulbrood in honeybees. The bacteria group also includes the Rickettsia, some species of which are pathogenic (particularly the Rickettsiella).ost of the non-spore-forming species of bacteria isolated from insects are in the families Enterobacteriaceae or Pseudomonidaceae. Non-spore-forming bacteria generally have low pathogenicity when they occur in the digestive tract of an insect, but may be very pathogenic if they are able to enter the insect's hemocoel.
