AI Article Synopsis
- The study focused on a species commonly found in natural pools in central Spain, assessing its ecological role and its potential as a respiratory pathogen.
- A new PCR assay was created to detect this species in both clinical and environmental water samples, revealing its presence mainly in raw and finished water.
- The research also identified the first case of Legionnaires' disease in Spain linked to this pathogen, emphasizing the importance of monitoring other bacteria in water sources for effective disease prevention.
Article Abstract
is one of the most frequent species isolated from natural pools of the central region of Spain. This study aimed to evaluate its ecology and to identify this species as a respiratory pathogen. A PCR assay for detecting the mip gene was developed to identify it in clinical and environmental samples. Culture and PCR were performed in environmental samples from four drinking water treatment plants (DWTPs). Free was only detected in raw water samples (3.4%), while as an endosymbiont was found in 30.7% of raw water, 11.5% of decanter biofilm, and 32% of finished water samples. Therefore, spp. plays an essential role in the multiplication, persistence, and spread of species in the environment. The first case of Legionnaires' disease caused by in Spain is described in this study. The case was diagnosed in an older woman through PCR and sequencing from urine and sputum samples. A respiratory infection could be linked with health care procedures, and the patient presented several risk factors (age, insulin-dependent diabetes, and heart disease). The detection of non-. , such as , is a factor that must be considered when establishing or reviewing measures for the control and prevention of legionellosis.

Currently, biopolymer-based Zn-containing nanoforms are of great interest for medical applications. However, there is lack information on optimal synthesis parameters, reagents and stabilizing agent for production of zinc carbonate nanoparticles (ZnC-NPs). In this work, synthesis of ZnC-NPs was carried out by chemical precipitation with the use of chitosan, hydroxyethyl cellulose, methyl cellulose and hyaluronic acid as stabilizing agents.

2-Ethylhexyl diphenyl phosphate (EHDPHP) is a widely used organophosphorus flame retardant and plasticizer easily released into the environment. Its biological toxicity is of great concern. The lung is considered a possible target organ for EHDPHP, but currently, there are limited studies on the biotoxicity of EHDPHP in poultry lungs.

The presence of trace metals (TMs) in river systems at certain levels can cause toxicity and pose significant risks to human health. In this study, nine TMs (Ba, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) were determined by inductively coupled plasma optical emission spectrometry (ICP-OES) in water samples collected from six major rivers from southwestern Nigeria during both dry and wet seasons. Across both seasons, the mean concentrations (mg/L) ranged from 0.

Waterfowl serve as indicators of ecosystem health and represent a pathway of contaminant exposure for hunters who consume them. In the northeast Atlantic Flyway, data on baseline contaminant loads in waterfowl are lacking. We assessed five species of commonly harvested (and consumed) waterfowl for mercury, polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans, polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), and per- and polyfluoroalkyl substances (PFAS).

Heavy metals in our direct environment have profound effects on human health and while some are essential for life, others can be toxic. In vivo studies often focus on clinical features caused by overexposure to, or by deprivation of a heavy metal. However, to understand the cellular impact of heavy metals on health, studies in healthy volunteers before symptom onset are needed.
