Which river had the highest number of somatic coliphages And what does that mean?
The highest somatic coliphage level detected in this study was 23 000.00 ± 989.95 pfp/100 mL in the Schoonspruit River.
What do you mean by coliphages?
A coliphage is a type of bacteriophage that infects coliform bacteria such as Escherichia coli. Examples include Bacteriophage lambda and Leviviridae.
Why T4 bacteriophage is called T4?
Escherichia virus T4 is a species of bacteriophages that infect Escherichia coli bacteria. It is a double-stranded DNA virus in the subfamily Tevenvirinae from the family Myoviridae….

What is non coliform bacteria?
Lactose Fermentors (or Total Non-Coliform Bacteria) are bacteria that grow under the same restrictive conditions as the Coliform bacteria but do not conform to the narrow definition of Coliforms. This group frequently contains enteric bacterial pathogens such as Aeromonas spp.
What is Moi in virology?
The multiplicity of infection or MOI is the ratio of infectious agents (e.g. phage or virus) to infection targets (e.g. cell).
What are the 3 types of phages?
Phages can also be categorized into three types according to their infection mechanism: (1) virulent phages always lyse the infected bacterial cell to release their progeny; (2) temperate phages can either enter the lytic cycle as virulent phages or enter the lysogenic cycle in which the phage genome is retained as a …
What is the difference between somatic and male specific coliphages?
Coliphages are classified as somatic or male specific. The somatic coliphages are DNA viruses that infect E. coli cell walls. Male-specific coliphages are either DNA or RNA viruses that infect through fertility (F) pili of Enterobacteriaceae bacteria.
What are coliphages and how do they work?
Coliphages are bacterial viruses which are specific to Escherichia coli and other coliforms. They can be divided into two groups. The somatic bacteriophages gain access to the cell through the cell wall and the F specific bacteriophages attach to the F or sex pilus.
What are the different types of coliphages?
There are two main groups of coliphages: somatic coliphages and male-specific (F-specific, or F +) coliphages ( Embrey, 2001; Scott et al., 2002 ). F + RNA coliphages may be classified into four main subgroups: group I, group II, group III, and group IV ( Scott et al., 2002; Sinton et al., 2002 ). Furuse (1987), using serotyping, concluded that
Can coliphages be used as indicators of groundwater quality?
Coliphages are viral structures and, compared with bacterial indicators, are more resistant to disinfection and diffuse further distances from pollution sources. Therefore, coliphage presence may serve as a better predictor of groundwater quality.
