NewsNew super pest combines broad spectrum of microbes
Researchers investigating what role the reed leafhopper’s microbial flora might have played in its rapid spread as a pest found it hosts at least seven species of bacteria and appears to be completely dependent on three of these species, which inhabit specific organs.

NewsFirst detection of zoonotic Rickettsia species in dog ticks from Malawi reveals potential public health risk
An international research team has reported the first molecular detection of Rickettsia bacteria in ticks collected from domestic dogs in Malawi, addressing a significant knowledge gap in understanding tick-borne disease risks in southeastern Africa.

NewsTick researchers identify new strain of rickettsia bacteria that causes spotted fever infections in humans
In a residential backyard in Maine, researchers stumbled upon a surprise finding: rabbit ticks harboring a new type of bacteria related to a group of pathogens that can cause sometimes life-threatening spotted fever rickettsioses (SFR) infections in humans.

NewsSymbiotic bacteria ride along with marine cells in ocean’s upper layer
Symbiotic bacteria often accompany single-celled protists in the ocean’s upper layer. Some of these symbionts, scientists have discovered, are close relatives of bacteria pathogenic to animals, including humans.

NewsMigrating birds have stowaway passengers: invasive ticks could spread novel diseases around the world
Ticks have always travelled on migrating birds — but the rising temperatures of the climate crisis mean they may now survive at their destination, and so could the pathogens they carry.

NewsNext-gen sequencing reveals array of pathogens in longhorned tick
A new study of microbial diversity in the longhorned tick indicates the high relative abundance of both pathogenic bacteria and non-pathogenic endosymbionts and the potential for pathogen transmission to residents of Shaanxi province.

NewsSymbiotic bacterium affects reproduction of biological control insect
Researchers have revealed that the symbiotic bacterium Rickettsia induces strong cytoplasmic incompatibility (CI) in the predatory mirid bug, Nesidiocoris tenuis, which preys on agricultural pests such as whiteflies and thrips.

NewsScientists pinpoint dominant pathogens in parasitic ticks in grazing areas
A new study maps the bacterium flora and identifies the main pathogens in ticks in grazing areas of Yunnan province in China.

News‘Subway map’ of Lyme disease pathways IDs potential treatment targets
Researchers have developed a genome-scale metabolic model of key metabolic activities of the bacterium that causes Lyme disease, successfully identifying two compounds that selectively target routes only used by Lyme disease to infect a host.
