AI Article Synopsis
- Wolbachia pipientis is a common symbiotic bacterium found in arthropods and filarial nematodes, and this study investigates its presence in spiders collected from Queensland, Australia.
- The research used PCR methods to identify diverse and closely related Wolbachia strains in spiders, some of which are outside the recognized supergroups A-F.
- Findings suggest horizontal transmission between spiders and Wolbachia, indicating that spiders can host multiple strains of the bacterium.
Article Abstract
Wolbachia pipientis is an endosymbiotic bacterium common to arthropods and filarial nematodes. This study presents the first survey and characterization of Wolbachia pipientis that infect spiders. All spiders were collected from Queensland, Australia during 2002-2003 and screened for Wolbachia infection using PCR approaches. The Wolbachia strains present in the spiders are diverse, paraphyletic, and for the most part closely related to strains that infect insects. We have also identified several spider Wolbachia strains that form a lineage outside the currently recognized six main Wolbachia supergroups (A-F). Incongruence between spider and Wolbachia phylogenies indicates a history of horizontal transmission of the bacterium in these host taxa. Like other arthropods, spiders are capable of harboring multiple Wolbachia strains.

Article Synopsis
- Dengue is a significant global health issue, and introducing Wolbachia bacteria into Aedes aegypti populations has been effective in reducing its transmission, though the impact on untreated areas is unclear.
- A synthetic control method was utilized to estimate the effectiveness of Wolbachia in reducing dengue incidence in Malaysia, comparing treated areas to non-treated control areas.
- The study found a substantial direct reduction of 64.35% in dengue cases in treated areas and a notable 37.69% reduction in adjacent untreated regions due to spillover effects.

Insects, like most animals, have intimate interactions with microorganisms that can influence the insect host's lipid metabolism. In this chapter, we describe what is known so far about the role prokaryotic microorganisms play in insect lipid metabolism. We start exploring microbe-insect lipid interactions focusing on endosymbionts, and more specifically the gut microbiota that has been predominantly studied in Drosophila melanogaster.
