Effect of Spiroplasma infection on the mating behavior of Glossina fuscipes fuscipes

Insect Science, EarlyView.
Abstract Tsetse flies are insects of significant public health and zoonotic importance as they are the main vectors of African trypanosomes. To date, an effective vaccine is unavailable and efforts to limit the spread of the disease primarily rely on controlling the tsetse populations.

Discrimination between transient and persistent bacteria harbored in the digestive tract of larval Galleria mellonella

Entomologia Experimentalis et Applicata, EarlyView.
The caterpillars of the greater wax moth (Galleria mellonella) (Lepidoptera: Pyralidae) are emerging models to study innate immunity and plastic biodegradation. Both of these processes are impacted by the associations between the insect host and its gut microbiome. Although bacterial flora harbored by the larvae have been characterized, little is known

Understanding Kink Propagation in Spiroplasma [PDF]

Biophysical Journal, 2010
Spiroplasma are helical bacteria of the class Mollicutes, that lack cell walls and swim by propagating a kink of handedness-change along their helical shaped body. Recent microscopy studies indicate that the major structural component of the cell is a multistranded protein ribbon, bound to the inner cell membrane.

The wall-less bacterium Spiroplasma poulsonii builds a polymeric cytoskeleton composed of interacting MreB isoforms

iScience, 2021
Summary: A rigid cell wall defines the morphology of most bacteria. MreB, a bacterial homologue of actin, plays a major role in coordinating cell wall biogenesis and defining cell shape.

An Intranuclear Sodalis-Like Symbiont and Spiroplasma Coinfect the Carrot Psyllid, Bactericera trigonica (Hemiptera, Psylloidea)

Microorganisms, 2020
Endosymbionts harbored inside insects play critical roles in the biology of their insect host and can influence the transmission of pathogens by insect vectors. Bactericera trigonica infests umbelliferous plants and transmits the bacterial plant pathogen

No Mate, No Problem: Molecular Mechanisms Involved in Parthenogenesis in the Cosmopolitan Earthworm Aporrectodea trapezoides (Annelida, Clitellata)

Molecular Ecology, EarlyView.
ABSTRACT Approximately, 40% of earthworm species can reproduce by parthenogenesis. This is the case for the cosmopolitan species, Aporrectodea trapezoides, although sexual forms have been described sporadically. We analyse the genotypes and microbiomes of 30 individuals from four localities where both forms appear in order to understand the ...

Coexistence of Two Chiral Helices Produces Kink Translation in Spiroplasma Swimming

Journal of Bacteriology, 2020
Many swimming bacteria generate a propulsion force by rotating helical filaments like a propeller. However, the nonflagellated bacteria Spiroplasma spp. swim without the use of the appendages.

Bifenthrin resistance in Dalbulus maidis (Hemiptera: Cicadellidae): inheritance, cross‐resistance, and stability

Pest Management Science, Volume 81, Issue 8, Page 4810-4820, August 2025.
Resistance of Dalbulus maidis to bifenthrin was autosomal, incompletely dominant, and polygenic. Additionally, this resistance was unstable in the absence of selection pressure. Abstract BACKGROUND Pyrethroid insecticides have been a primary strategy for managing Dalbulus maidis (Hemiptera: Cicadellidae) in Brazil. Howeve, failures in the control of D.

Influences of plant maternal effects, chemotype, and environment on the leaf bacterial community

Plant Biology, Volume 27, Issue 5, Page 903-912, August 2025.
Plant maternal effects and growth environment, rather than terpenoid chemotype, determine the leaf microbial community of Tanacetum vulgare, but specific terpenoids are correlated with the abundance of certain bacteria. Abstract Plant individuals within a species can differ markedly in their leaf chemical composition, forming so‐called chemotypes ...

Microplate Active Migration Emerging From Light‐Induced Phase Transitions in a Nematic Liquid Crystal

Advanced Functional Materials, Volume 35, Issue 30, July 24, 2025.
A quasi‐2D, light‐absorbing platelet embedded in a thermotropic nematic liquid crystal is activated with light irradiation. Depending on the light intensity, the platelet induces a localized nematic‐isotropic phase transition that triggers the motion. Using different confinements, the platelet can glide in a 2D regime or tilt and glide in a 3D regime ...
