Handbook of Water and Wastewater Microbiology
"Access to safe water is a fundamental human need and therefore a basic human right" --Kofi Annan, United Nations Secretary General
Edited by two world-renowned scientists in the field, The Handbook of Water and Wastewater Microbiology provides a definitive and comprehensive coverage of water and wastewater microbiology. With contributions from experts from around the world, this book gives a global perspective on the important issues faced in the provision of safe drinking water, the problems of dealing with aquatic pollution and the processes involved in wastewater management.
Starting with an introductory chapter of basic microbiological principles, The Handbook of Water and Wastewater Microbiology develops these principles further, ensuring that this is the essential text for process engineers with little microbiological experience and specialist microbiologists alike.

2.1 Representative virus particles. Human viruses (a–e) are relatively simple
when compared with the T-even bacteriophage that infects Escherichia coli (f).
Many virus types are icosahedral (a). Icosahedral viruses include enteroviruses
2.2 Representative virus life cycle. The enterovirus virion approaches the surface
of the cell to be infected (I). It penetrates the cell to infect it (II), and virus RNA
passes into the cytoplasm as the virus is uncoated (III). Non-structural proteins
Samples of water for virological examination may contain very small numbers of
virus particles. It is thus necessary to treat the samples to concentrate any viruses
that may be present so that they may be detected more easily. If they cannot be ...
comparison the percentage recovery of virus particles can be calculated: Virus
particles recovered Virus particles input £ 100% When using the concentration
procedure described above the recovery of virus particles is typically between 60
The only problem with using PCR technology to detect viruses is that it detects
the total number of virus particles in a sample. It gives no indication of the
proportion of virus particles that are potentially infectious. It may thus seriously ...
