Lemon balm is herbal tea used for soothing stomach cramps, indigestion, and nausea. Rosmarinic acid (RA) is one of its chemical constituents known for its therapeutic potentials against cancer, inflammatory and neuronal diseases such as the treatment of neurofibromatosis or prevention from Alzheimer's diseases (AD). Despite efforts, recovery and purification of RA in high yields has not been entirely successful.

Baculoviruses infect insects, producing two distinct phenotypes during the viral life cycle: the budded virus (BV) and the occlusion-derived virus (ODV) for intra- and inter-host spread, respectively. Since the 1980s, several countries have been using Anticarsia gemmatalis multiple nucleopolyhedrovirus (AgMNPV) as a biological control agent against the velvet bean caterpillar, A. gemmatalis.

Examination by epifluorescent and transmission electron microscopy revealed that the bacteria covered the luminal surface of the crypts and filled the entire lumen. Attempts to culture the extracellular endosymbionts in various media failed.

Transmission electron microscopy revealed fully assembled nucleocapsid-like particles (NLPs) exhibiting the typical helical herringbone morphology. These NLPs were approximately 20-22 nm in diameter and varied in length from 50 to 100 nm.

Although TSV does not cause hemorrhagic fever as some other members of its family, serological studies have shown that serum from Florida residents react against TSV indicating viral infection in humans. In this study, the three RNA genome segments of a TSV isolated from Anopheles crucians mosquitoes collected in North Central Florida in 2006 and a TSV isolate obtained from the CDC, Fort Collins, were sequenced and compared to other Bunyaviridae.

The transcriptome of this newly described virus was analysed by rapid amplification of cDNA 3'-ends (3'-RACE) and RT-PCR. Direct sequencing of 3'-RACE products revealed 78 poly(A) transcripts containing 95 of the 108 putative ORFs.

They share general characteristics with the non-occluded insect nudiviruses, such as being insect-pathogenic, having enveloped, rod-shaped virions, and large circular double-stranded DNA genomes. MdSGHV measures 65x550 nm and contains a 124 279 bp genome (approximately 44 mol% G+C content) that codes for 108 putative open reading frames (ORFs).

Three ORFs were unique to AgMNPV-2D, one of which (ag31) had similarity to eukaryotic poly(ADP-ribose) polymerases.

Their genomes were small in size (86,462 and 81,755 bp, respectively), had low G+C contents (33.8 and 33.
