The Effects of a Mixture of Monochromatic Green and Blue Light on Growth Performance and Immune Response in Bursa of Fabricius by Morphometry Using Staining and Immunohistochemistry in Broiler Chickens
(MDPI, 2026-04-17) Horodincu, Loredana; Cotrutz, Victor; Herțanu, Radu; Petrovic, Adriana; Popovici, Ivona; Solcan, Gheorghe; Ciubotariu,Alexandra; Henea, Mădălina; Galan, Lenuța; Pogoreanu, Rareș; Dinuț-Cebuc, Adina-Ștefana; Stafie, Silviu; Solcan, Carmen
The use of colored LED lights is a tool for controlling the development of lymphoid organs and the immune system in general. This study aims to analyze the effects of using simple and combined colored LED lights throughout a 6 week period (1–42 days of age). In this study, 336 one-day-old chicks were used, separated randomly into four groups with different sex and lighting systems, with each group being divided into four separate replicates (4 × 21 birds). The chicks in the WL-Male and WL-Female were exposed to white LED light (WL, 400–760 nm) for 6 weeks, while the chicks in the G-GxB-BL-Male and G-GxB-BL-Female were exposed to a combination of monochromatic lights as follows: green (560 nm) from 1 to 14 days of age, green and blue (480–560 nm) for 15–28 days of age, and blue lights (480 nm) for 29–42 days of age. The use of a mixture of green and blue LED lights (G-GxB-BL) resulted in a significant decrease in the average daily feed intake and feed conversion ratio compared to white light, without causing changes in the body weight of the chicks, average daily gain, mortality rate, and coefficient of variability. G-GxB-BL lights also improved the morphological development of the bursa of Fabricius (BF) compared to white light by significantly increasing the organ index and the lymphoid follicle area. At the same time, G-GxB-BL light compared to white light improved B lymphocytes proliferation in the BF by significantly increasing the lymphocyte density in lymphoid follicles, as well as the number of PCNA-positive cells. This light treatment had these results due to the activation of melatonin receptors, which led to a significant increase in Mel1a-positive cells and a significant decrease in the number of RORα-positive cells. These results demonstrate that G-GxB-BL lights improved the growth performance and immune response in the BF of broiler chickens.

Risk Factors and Antibiotic Utilization Patterns in Multidrug-Resistant Surgical Infections: A Retrospective Study From a Romanian Tertiary-Care Center
(Wiley, 2026-06-19) Ambrosie, Lucian; Dan, Maria; Ilie, Ovidiu-Dumitru; Condrea, Tabita-Daniela; Purice, Mihaela; Blaj, Mihaela; Ionescu, Lidia; Timofte, Daniel-Vasile
Background Multidrug-resistant (MDR) infections represent a major challenge in surgical patients, particularly in settings with prolonged hospitalization and intensive care exposure. Identifying risk factors and their impact on mortality is essential for optimizing antimicrobial stewardship and infection control strategies. Methods We conducted a retrospective observational study including surgical patients admitted to a Romanian tertiary-care hospital between 2020 and 2022. Demographic, clinical, microbiological, and antibiotic utilization data were analyzed using multivariate logistic regression and receiver operating characteristic (ROC) curve analysis to identify factors associated with MDR infection and in-hospital mortality. Results Prolonged intensive care unit (ICU) stay and longer hospitalization were the main independent predictors of MDR infection. Antibiotic prophylaxis was also associated with MDR status, likely reflecting increased antimicrobial exposure in high-risk patients, while a higher comorbidity burden showed an inverse association. MDR infections were strongly associated with increased in-hospital mortality and remained an independent predictor after adjustment, alongside ICU stay and older age. MDR cases were characterized by more frequent use of broad-spectrum antibiotics, whereas non-MDR patients more commonly received narrower-spectrum regimens. The most frequent MDR pathogens included Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii. Conclusions MDR infections in surgical patients are primarily driven by prolonged healthcare exposure, particularly ICU admission and extended hospitalization. These findings highlight the importance of targeted infection control measures and optimized antimicrobial use to reduce mortality and limit the spread of resistance.

Edema and Structural Remodeling in Equine Suspensory Ligament Injury: A Severity Gradient Associated with Microvascular Dysfunction
(MDPI, 2026-05-08) Lazăr, Constantin; Vulpe, Vasile; Baisan, Andrei-Radu; Pivariu, Dalma; Bora, Florin-Dumitru; Crecan, Cristian-Mihăiță
Suspensory ligament injury is a major cause of lameness in sport horses, yet its underlying mechanisms remain incompletely understood. The aim of this study was to characterize histopathological alterations of the equine suspensory ligament and to evaluate their association with imaging features. A comparative descriptive study was performed on sport horses with forelimb lameness, combining clinical evaluation, ultrasonography, magnetic resonance imaging, and histopathological analysis. Ligament samples were collected post-mortem from anatomically defined regions selected based on imaging findings to allow regional imaging–histopathology correlation. The results showed a consistent presence of edema in perivascular, interfascicular, and intrafascicular compartments, indicating a diffuse disturbance of tissue fluid balance. Lesions with lower severity were characterized by increased vascular permeability and mild extracellular matrix expansion, whereas lesions with greater structural severity demonstrated vascular remodeling, including endothelial thickening, vascular wall changes, and perivascular connective tissue proliferation, associated with collagen disorganization. Regional differences were observed, with more pronounced alterations in the proximal region compared to the branch region. These findings are consistent with a pattern of structural changes associated with microvascular alterations, demonstrating variation in lesion severity across samples and supporting an association between imaging categories and semi-quantitative histological features. However, given the cross-sectional design, causality cannot be established.

Effect of feeding rate on growth performance of A. stellatus (Pallas, 1771) reared in a recirculating aquaculture system
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Petrea, Șt.-M.; Mogodan, Alina; Simionov, Ira-Adeline; Cristea, V.
Recirculating aquaculture systems (RAS) represents the most suitable solution for rearing sturgeons in intensive conditions, situation which imposes the use of a proper technology, respectively feeding rate, for a certain fish development stage. The aim of present study is to evaluate the effect of feeding rate on growth performance of stellate sturgeon (330.55±44.27 g) reared in RAS conditions. Two feeding rates were tested (F1 - 1% BW, respectively F2 - 2% BW), in replicate Biomass measurements were made at the middle of the experimental period, in order to adjust the daily administrated feed quantity. The average specific growth rate indicates a superior fish production at F2 (1.15 %BW/day), compared to F1 (0.65 %BW/day) experimental variant. However, from the perspective of feeding strategy efficiency, the average food conversion ratio (FCR) indicates better values for F1 experimental variant (1.5 g feed/g biomass gain), compared to F2 (1.61 g feed/g biomass gain). The protein efficiency ratio (PER) registered higher values at F1 experimental variant (1.67), compared to F2 (1.53), revealing the ability of fish organism to utilize proteins, which positively affects growth rate. Therefore, as a conclusion, it can be stated that during the analyzed stellate sturgeon development stage a better cost efficiency is recorded when applying 1% BW feeding rate, although if production maximization is targeted, 2% BW feeding rate is recommended.

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Al.A. Casapu; Cazacu, Cristina-Petronela; Arsinte, P.R.; Nistor, Cătălin-Emilian; Hoha, Gabriel; Păsărin, Benone
This study is conducted for the period 2014 - 2018 with the purpose of monitoring the quantity and quality of the swine carcases that are classified with SEUROP system in Romania. For determining the thickness of the Longissimus dorsis and the thickness of the dorsal fat there were used the equipments OptiGrade–Pro, Fat-O-Meat'er and Ruler. The data regarding the swine livestock evolution, abatorizations and classifications performed Romania came from the reports of the Commission of Carcass Classification transmitet towards European Commission. Through the study it was found, for the year 2018, that the swine livestock decreased by over 500,000 heads. This decrease of the livestock is placed on the base of the occurrence and spread of African swine fever in most counties of the country. The study also highlighted some constant factors of the 5 years such as: increase of the average carcass weight from 80.6 to 84.2 kg and the quantity of lean meat in the carcass from 47.2 to 49.56 kg.
