Many of the enteric viruses which are transmitted from person to person by the fecal-oral route are found in raw and treated wastewater, and because of their persistence under adverse conditions may also be found in slightly polluted waters. There is no routine examination procedure of water and wastewater for enteroviruses, mainly because of the ...

The chapter discusses on the various small bacteriophages. These phages are quite heterogeneous; some species contain DNA and others contain ribonucleic acid (RNA); some particles have cubic symmetry and others are made of a helical nucleoprotein structure.

Abstract In complex DNA bacteriophages like λ, T4, T7, P22, P2, the DNA is packaged into a preformed precursor particle which sometimes has a smaller size and often a shape different from that of the phage head. This packaging mechanism is different from the one suggested for the RNA phages, according to which RNA nucleates the shell ...

AbstractNaturally occurring defective phage particles, which do not form plaques on any known host, but have a restricted host killing range, appear to be widely distributed. The defective phages are produced spontaneously but can be induced, at much higher levels, by chemical and physical agents which interfere with metabolism or structure of DNA. The

Bacteriophages are ubiquitous to the rumen ecosystem; they have a role in nitrogen metabolism through bacterial lysis in the rumen, they may help to regulate bacterial population densities, be an agent for genetic exchange and be of use in biocontrol of bacterial populations through phage therapy [10, 11, 19]. In Chapter 2.1, classical methodologies to

Abstract Mu was the first mobile genetic element identified in prokaryotes. Since its first isolation, in 1963, it has attracted the interest of many biologists. This interest is a consequence of its double nature: Mu is both a bacteriophage and a transposon. Studies on Mu began when L.

There is currently a handful of genome sequences available for tailed bacteriophages with genomes of more than 200 kbp of DNA, designated here as giant or jumbo phages. The majority of the proteins predicted from the genome sequences of these phages have no matches in the current sequence databases, and the genomes themselves are diverse enough to ...

Phages are called "good viruses" due to their ability to infect and kill pathogenic bacteria. Chlamydia are small, Gram-negative (G-) microbes that can be dangerous to human and animals. In humans, these bacteria are etiological agents of diseases such as psittacosis or respiratory tract diseases, while in animals, the infection may result in enteritis

In the last phase of their life cycle, bacteriophages form lytic enzymes known as bacteriophage endolysins that destroy the bacterial cell wall and liberate new virions. Endolysins have emerged as high-scope antimicrobial agents, especially against Gram-positive infections, due to their specificity, rapid action, and ability to target essential cell ...
