Provided are non-propagating transgenic microalgae expressing at least one heterologous RNAi molecule. The RNAi-expressing non-propagating transgenic microalgae are used for oral delivery of the RNAi molecule to a target organism in its intact and functional form. The heterologous RNAi molecule, present within the microalgae, is characterized by being biologically active, exerting at least one specific effect on the organism consuming the microalgae or on a pathogen of said organism. In particular, the non-propagating transgenic microalgae are used as agents for biological control of animal and plant pests.

The present invention relates to a novel bacteriophage CJ28 (KCCM11466P) and a composition containing the same as an active ingredient. Further, the present invention relates to a method for preventing and/or treating infective diseases caused by enterotoxic Escherichia coli (ETEC) of animals excluding humans by using the composition. A bacteriophage CJ28 (KCCM11466P) has a specific ability to kill enterotoxigenic Escherichia coli.

Provided herein are agents, compositions, and methods for agricultural use, e.g., for altering the level, activity, or metabolism of one or more microorganisms resident in a host nematode or arthropod (e.g., honeybee or silkworm), the alteration resulting in an increase in the fitness of the host. The invention features a composition that includes an agent (e.g., phage, peptide, small molecule, antibiotic, or combinations thereof) that can alter the host's microbiota in a manner that is beneficial to the host. By promoting favorable microbial levels, microbial activity, microbial metabolism, and/or microbial diversity, the agents described herein may be used to increase the fitness of a variety of beneficial nematodes or arthropods, such as bees and silkworms, utilized in agriculture and commerce.

An object of the present invention is to provide a method for efficiently obtaining a lactic bacterium having a high double-stranded RNA content obtained by the method. The object is achieved by: (1) a method for producing a double-stranded RNA-containing lactic acid bacterium, including a step of culturing a lactic acid bacterium under at least one condition of an aeration condition and a low-temperature condition lower than an optimum temperature, thereby obtaining the double-stranded RNA-containing lactic acid bacterium; (2) a double-stranded RNA-containing lactic acid bacterium, in which the content of double-stranded RNA is 2.0 times or more as compared with the content of double stranded RNA when a bacterium of the same strain is cultured for the same culture time under an optimum temperature and non-aeration condition; or the like.
