“…Other transducing phages have been reported for B. anthracis , B. cereus and B. thuringiensis , but unfortunately there is little information available about them, and therefore they will be not discussed here. In addition, Sorokin has addressed the potential existence of other transducing phages among the available B. cereus group phage genome sequences in an excellent analysis (for a review see [ 150 ]).…”

“…Some prophages have been detected while sequencing the whole genome of particular bacterial strains. For example, the B. weihenstephanensis strain KBAB4 has what it seems to be an inducible prophage of 53 kb named pBWB404 [ 150 , 214 ]. Also, as previously addressed, this B. weihenstephanensis strain presents a phage-like region that is partially homologous to the B. thuringiensis jumbo-phage 0305ϕ8-36 (referred in Section 4.5 .).…”

Many bacteriophages (phages) have been widely studied due to their major role in virulence evolution of bacterial pathogens. However, less attention has been paid to phages preying on bacteria from the Bacillus cereus group and their contribution to the bacterial genetic pool has been disregarded. Therefore, this review brings together the main information for the B. cereus group phages, from their discovery to their modern biotechnological applications. A special focus is given to phages infecting Bacillus anthracis, B. cereus and Bacillus thuringiensis. These phages belong to the Myoviridae, Siphoviridae, Podoviridae and Tectiviridae families. For the sake of clarity, several phage categories have been made according to significant characteristics such as lifestyles and lysogenic states. The main categories comprise the transducing phages, phages with a chromosomal or plasmidial prophage state, γ-like phages and jumbo-phages. The current genomic characterization of some of these phages is also addressed throughout this work and some promising applications are discussed here.

“…Transducing phages of B. cereus s.l. are grouped into three categories, based on their size and host range (Sorokin, 2012). A restricted host spectrum characterizes smaller phages.…”

“…For instance, the genome of B. thuringiensis strain 4042B was mapped using the phages TP13 and TP18 (Barsomian et al, 1984). Given its insecticidal properties, B. thuringiensis was the main focus of most transduction-based studies in the B. cereus group (Sorokin, 2012).…”

Horizontal gene transfer (HGT) is a major driving force in shaping bacterial communities. Key elements responsible for HGT are conjugation-like events and transmissible plasmids. Conjugative plasmids can promote their own transfer as well as that of co-resident plasmids. Bacillus cereus and relatives harbor a plethora of plasmids, including conjugative plasmids, which are at the heart of the group species differentiation and specification. Since the first report of a conjugation-like event between strains of B. cereus sensu lato (s.l.) 40 years ago, many have studied the potential of plasmid transfer across the group, especially for plasmids encoding major toxins. Over the years, more than 20 plasmids from B. cereus isolates have been reported as conjugative. However, with the increasing number of genomic data available, in silico analyses indicate that more plasmids from B. cereus s.l. genomes present self-transfer potential. B. cereus s.l. bacteria occupy diverse environmental niches, which were mimicked in laboratory conditions to study conjugation-related mechanisms. Laboratory mating conditions remain nonetheless simplistic compared to the complex interactions occurring in natural environments. Given the health, economic and ecological importance of strains of B. cereus s.l., it is of prime importance to consider the impact of conjugation within this bacterial group.
