“…Regarding services of BALO populations in the environment, diversity is likely an important factor, especially relative to their potential function in controlling and shaping bacterial communities through selective mortality, which may be dependent upon the specific predator OTUs present. This hypothesis is consistent with the observation in this and other studies (Davidov et al, 2006;Rogosky et al, 2006) that not all Bacteriovorax OTUs are equal in their ability to prey on various bacteria. For example, based on the results reported here, the presence of Clusters IX and X in an environmental niche would be expected to be more important factors, than other clusters in contributing to the mortality of Vv populations in that situation.…”

“…However, unique properties of Bacteriovorax Clusters IX and X, which allow them to overcome the prey exclusion, may explain the differential predation efficiency on the two preys but further investigation is needed. Preferential predation of BALOs on certain bacteria species has been reported (Rogosky et al, 2006); however, no known selective mechanisms such as receptor sites or chemotaxis toward a specific prey have been identified.…”

“…Studies have examined the influence of BALO isolates on the bacteria prey community. In one study, in which a single BALO isolate was inoculated into a suspension of several bacterial species, the predator was observed to preferentially prey on certain bacteria (Rogosky et al, 2006). However, to show the influence of any selective pressure of the prey on the selection of predators, requires a corollary study to investigate the response of multiple Bacteriovorax OTUs to a single prey species.…”

Although predator-prey interactions among higher organisms have been studied extensively, only few examples are known for microbes other than protists and viruses. Among the bacteria, the most studied obligate predators are the Bdellovibrio and like organisms (BALOs) that prey on many other bacteria. In the macroscopical world, both predator and prey influence the population size of the other's community, and may have a role in selection. However, selective pressures among prey and predatory bacteria have been rarely investigated. In this study, Bacteriovorax, a predator within the group of BALOs, in environmental waters were fed two prey bacteria, Vibrio vulnificus and Vibrio parahaemolyticus. The two prey species yielded distinct Bacteriovorax populations, evidence that selective pressures shaped the predator community and diversity. The results of laboratory experiments confirmed the differential predation of Bacteriovorax phylotypes on the two bacteria species. Not only did Bacteriovorax Cluster IX exhibit the versatility to be the exclusive efficient predator on Vibrio vulnificus, thereby, behaving as a specialist, but was also able to prey with similar efficiency on Vibrio parahaemolyticus, indicative of a generalist. Therefore, we proposed a designation of versatilist for this predator. This initiative should provide a basis for further efforts to characterize the predatory patterns of bacterial predators. The results of this study have revealed impacts of the prey on Bacteriovorax predation and in structuring the predator community, and advanced understanding of predation behavior in the microbial world.

“…For example, B. bacteriovorus 109J can be grown on certain strains of Escherichia, Pseudomonas, Rhizobium, Chromatium, Spirillum, as well as other genera (Ruby, 1991). In mixed prey cell populations, B. bacteriovorus 109J does not randomly infect prey cells but infects and kills some prey more readily than others (Rogosky et al, 2006). Bdellovibrio were intensively studied in the 1960s and 1970s with the developmental stages observed microscopically and partially assayed biochemically (Lambert et al, 2006).…”

“…BALOs have a wide prey range, but the way they select their prey is not well understood (Rogosky et al 2006. Bdellovibrio directs itself towards its prey by flagellar motility and chemotactic responses (Straley & Conti 1977, Lambert et al 2003.…”

Acute hepatopancreatic necrosis disease, a severe disease of shrimp, is caused by Vibrio parahaemolyticus (AHPND Vp), a halophilic bacterium harboring a plasmid that contains toxin genes homologous to Photorhabdus insect-related toxins. We obtained 9 isolates of Bdellovibrio and like organisms (BALOs) from water and sediment samples in Thailand. Using 16S rRNA sequencing, all of the organisms were identified as Bacteriovorax spp. and were able to attack all tested AHPND Vp isolates. In addition, their various susceptible hosts, including Gram-positive and Gram-negative bacteria, were observed. The optimal ratio for interaction between the Bacteriovorax isolate BV-A and AHPND Vp was determined to be 1:10. The suitable conditions applied for co-culture between BV-A and AHPND Vp were 30°C, 2% NaCl, and pH 7.6. The capability of BV-A to reduce numbers of AHPND Vp in vitro was observed in co-culture after incubation for 2 d and continued until the end of the incubation period. In vivo, BV-A was able to reduce mortality of shrimp post-larvae infected with AHPND Vp. In addition, BV-A significantly decreased the formation of biofilm by AHPND Vp. These findings provide evidence for using Bacteriovorax as a biocontrol of AHPND Vp in shrimp aquaculture.
