Background: The purpose of this study was to evaluate the epidemiology and investigate the impact of colonization and pulmonary fungal infections (PFIs).
Methods: In this investigation we performed a retrospective analysis of 55 pediatric lung transplant recipients from 2002 to 2007 at a single institution. Associations between risk factors and time to post-transplant colonization, PFI, and other outcomes were assessed using Cox proportional hazard models.
Results: Although 29 patients had positive pre-transplant colonization, 33 (60%) were colonized post-transplant and 20% (11 subjects) developed proven or probable PFI. In a multivariate model, post-transplant fungal colonization was associated with older age (hazard ratio [HR] 2.9, 95% confidence interval [CI] 1.1 to 7.6), cytomegalovirus (CMV) prophylaxis (HR 5.6, 95% CI 1.3 to 24.6) and respiratory viral infection prior to fungal colonization (HR 2.9, 95% CI 1.0 to 8.3).
Conclusion: Neither fungal colonization nor PFI was associated with the development of chronic allograft rejection or death.

Maize () is India's third-largest grain crop, serving as a primary food source for at least 30% of the population and sustaining 900 million impoverished people globally. The growing human population has led to an increasing demand for maize grains. However, maize cultivation faces significant challenges due to a variety of environmental factors, including both biotic and abiotic stresses.

-a mycotoxigenic fungus and food safety threat-coinhabits maize kernels with . This protective endophyte produces secondary metabolites of interest, pyrrocidines A and B, which inhibit the growth of and specifically block fumonisin biosynthesis. Previous transcriptomic analyses found (FVEG_00314), a gene adjacent to the fumonisin biosynthetic gene cluster, to be induced over 4,000-fold in response to pyrrocidine challenge.

Background: The early colonization and establishment of the microbiome in newborns is a crucial step in the development of the immune system and host metabolism. However, the exact timing of initial microbial colonization remains a subject of ongoing debate. While numerous studies have attempted to determine the presence or absence of intrauterine bacteria, the majority of them have drawn conclusions based on sequencing data from maternal or infant samples taken at a single time point.

Objective: Helicobacter pylori is known for colonizing the gastric mucosa and instigating severe upper gastrointestinal diseases such as gastritis, gastroduodenal ulcers, and gastric cancer. To date, there is no data available on the oral cavity as transmission site, whether H. pylori can survive in the oral cavity or in human saliva.

To understand the interactions of entomopathogenic fungi with forage plants and their influence on associated herbivorous, we evaluated the influence of endophytic colonization with three isolates (CEPAF_ENT 25, CEPAF_ENT 27, and IBCB 425) of Metarhizium anisopliae on Cynodon dactylon, regarding the biological and behavioral aspects of Collaria scenica, an emerging sucking pest in pastoral systems in Brazil. The application of suspensions at the base of plant (drench) was effective in promoting endophytic colonization, especially in the roots, with emphasis on isolates CEPAF_ENT25 and CEPAF_ENT27. Despite the significant reduction in damage caused by C.
