Infected agents

Specific biological activity of carboxylic acids peroxide derivatives in compaiison with their oxidation ability and ionization degree in aqueous solutions has been considered. Peroxyoctanoic, diperoxynonandioic and diperoxydecandioic acids give the most intense bactericidal effect among researched cai boxylic acids peroxide derivatives. The perspectives of use of the aliphatic middle-chain peracid C8-C9 as anti-infective agents have been discussed. 

Potable water Water that does not contain objectionable pollution, contamination, minerals, or infective agents and is considered satisfactory for drinking. 

Virus Any of a large group of submicroscopic infective agents that typically contain a protein coat sunounding a nucleic acid core and are capable of growth only in a living cell.

Inflammatory materials are released fiom necrotic cells and directly fixm the infective agent. It is not always clear to what extent these can be related to actions by the host or by the pathogen. Inflammation causes swelling, pain and reddening of the tissues, and sometimes loss of function of the organs affected. These reactions may sometimes be the major sign and symptom of the disease.

Propagated outbreaks of infection relate to the direct transmission of an infective agent from a diseased individual to a healthy, susceptible one. Mechanisms of such transmission were described in Chapter 4 and include inhalation of infective aerosols (measles, mumps, diphtheria), direct physical contact (syphilis, herpes virus) and, where sanitation standards are poor, through the introduction of infected faecal material into drinking water (cholera, typhoid). The ease oftransmission, and hence the rate of onset of an epidemic (Fig. 16.3) relates not only to the susceptibility status, and general state of health of the individuals but also to the virulence properties of the organism, the route oftransmission, the duration of the infective period associated with the disease.

Sometimes pollution is acceptable in small amounts. When Columbus landed in the New World there were an estimated 15,000 Indians living in the area that is now Ohio (1970 population 10,652,017). Did these Indians pollute the environment They made open tires, something that is now banned in all municipal areas, and they urinated and defecated at large. Still, since they were so few in number, the cleansing actions of the air, water and biosphere could rapidly assimilate then-wastes and no accumulating harm was done. In the strict sense of the word pollution, they did dirty the streams and anyone drinking the water shortly afterwards could contract the diseases whose infective agents were present in their wastes. However, with a little care this was unlikely, and their pollution was not considered bad.

Regulatory guidance for the conduct of clinical trials on vaccines is specific. Traditional phase I trials in normal volunteers are not conducted. Rather, all trials assess not only safety but also efficacy (or at least immunogenicity). Trials may well be challenge trials, that is, after immunization subjects are purposely challenged with exposure to the infective agent of concern. 

CSF levels in normal human serum are usually low or undetectable. During infections, the immune system responds by activation of leukocytes, and often this is accompanied by an increase in numbers of specific leukocytes in the circulation in order to combat the infective agent. Thus, it is not surprising that many pathogens activate CSF production, which then results in increases in numbers of progenitor cells in the bone marrow and spleen, and subsequent increases in numbers of mature leukocytes in the circulation.
