Growth and Nutrition of Mollicute-Infected Maize [PDF]

Plant Disease, 2002
Maize bushy stunt phytoplasma (MBSP) and corn stunt spiroplasma (CSS) diseases are widespread in Brazil. The leafhopper Dalbulus maidis is the insect vector for these pathogenic mollicutes. The effects of these diseases on the development of maize plants and the possible interaction of soil water availability on these effects were evaluated in two ...

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

Insect Science, Volume 32, Issue 5, Page 1726-1736, October 2025.
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.

Nitrogen and Potassium Fertilization Modulate Dalbulus maidis (HEMIPTERA: CICADELLIDAE) Abundance and Corn Stunt Disease Severity

Agriculture
Corn stunt complex, transmitted by the corn leafhopper (Dalbulus maidis), poses significant yield risks to corn production. This study evaluated the effects of two corn hybrids and top-dressed nitrogen (N) and potassium (K) fertilization on D.

Recent data on the causative agent of pale green dwarf (Acholeplasma laidlawii var. granulum incertae sedis) in Ukraine: pathogenicityand virulence factors and host reactions

Agricultural Science and Practice, 2015
Contemporary state of the distribution of mycoplasma diseases of cultivated crops in Ukraine was analyzed. The changes of the physiological state of plant cells under the impact of mollicutes were investigated. It was demonstrated that there is temporary

Observational study to determine the proportion of first milking colostrum from Scottish dairy herds positive for Mycoplasmopsis bovis

Veterinary Record, Volume 197, Issue 5, 6/13 September 2025.
Abstract Background Mycoplasmopsis bovis causes a range of clinical conditions, including mastitis, arthritis, otitis and bronchopneumonia. Proposed transmission routes include semen, milk, colostrum, aerosol, nose‐to‐nose contact and fomite spread. Methods Seventy‐nine composite colostrum samples were collected directly from cows’ teats on 10 farms in

Causal Mediation Role of Immune Cells in Gut Microbiota–Pneumonia Associations: A Mendelian Randomisation Study

Journal of Cellular and Molecular Medicine, Volume 29, Issue 17, September 2025.
ABSTRACT The gut–lung axis plays a pivotal role in pneumonia pathogenesis, with immune regulation serving as a key mechanistic link between gut microbiota and disease progression. Despite established associations among gut microbiota, immune cell traits and pneumonia, their causal interplay and underlying mechanisms remain poorly elucidated.

Deciphering the Potential Causal and Prognostic Relationships Between Gut Microbiota and Brain Tumors: Insights from Genetics Analysis and Machine Learning

Exploration, Volume 5, Issue 4, August 2025.
The causal relationship between gut microbiota and brain tumors and potential prognostic value of microbiota are still unclear. This study confirmed the causal effects of specific gut microbiota on three common brain tumors and identified microbe‐related genes that are expressed in brain tissue and correlated with the abundance of gut microbiota ...

Evaluating Effects of Antibiotics Across Preclinical Models of the Human Gastrointestinal Microbiota

MicrobiologyOpen, Volume 14, Issue 4, August 2025.
We compared microbiota changes following antibiotic treatment in two preclinical models of the human GI microbiota, minibioreactor arrays (MBRAs) and human microbiota associated mice (HMAmice). MBRAs and HMAmice were colonized with feces from 12 or 3 healthy humans, respectively, before treatment with each of 12 or 6 antibiotics.
