Background: Feline lower urinary tract disease (FLUTD) is a common disorder associated with the dysfunction of the urinary bladder or urethra in tomcats.

Aim: A prospective study was carried out on the point prevalence and odds ratio (OR) of the FLUTD in Shirazi and Baladi tomcats at Ismailia Governorate, Egypt, recording the prominent clinical manifestation and identifying the antibiogram, virulence, and antimicrobial resistance genes of the causative microorganisms.

Methods: A total number of 420 tomcats admitted to the veterinary clinics of Ismailia during the period June 2020 to May 2021 were examined for FLUTD. A total of 1,260 urine samples were collected and analyzed.

Results: Hematuria, dysuria, and pollakiuria were the most evident signs recorded in a total of 120 tomcats diagnosed with FLUTD. The diagnosed cases of FLUTD were associated with causes like crystals (35.83%), pyogenic microorganisms (19.16%), and mixed cases (45.00%). The prevalence revealed highly significant ( < 0.01) increases in the cases caused by , mixed cases, and calcium oxalate at >4 years; at ≤ 2 years; amorphous urate and phosphate at 2-4 and >4 years in Shirazi and ≤2 years in Baladi; triple phosphate at ≤2 years in Shirazi and >4 years in Baladi; and mixed cases at ≤2 years. The OR of FLUTD revealed higher odds of associations with , mixed cases, , amorphous urate, and triple phosphate, as well as lower odds with , calcium oxalate, amorphous phosphate, and mixed cases. Isolated revealed higher resistance to amoxicillin (AMX, 83.4%), ceftriaxone (83.4%), ceftazidime (CAZ, 75.0%), and cefoxitin (FOX, 50.0%), and to oxacillin (100%), FOX (100%), AMX (85.8%), CAZ (76.2%), and FOX (50.0%). -detected virulence genes were , , , and , and were , , , , , , and . About 100% of and 76.1% of isolates exhibited multidrug resistance.

Conclusion: FLUTD in tomcats is associated with higher odds in , mixed cases, and triple phosphate at older ages (>4 years) with high antimicrobial resistance in the microbial isolates contributing to the disease.

Resonant Emittance Mixing of Flat Beams in Plasma Accelerators.

Phys Rev Lett

December 2024

Deutsches Elektronen-Synchrotron DESY, Notkestrasse 85, 22607 Hamburg, Germany.

Linear colliders rely on high-quality flat beams to achieve the desired event rate while avoiding potentially deleterious beamstrahlung effects. Here, we show that flat beams in plasma accelerators can be subject to quality degradation due to emittance mixing. This effect occurs when the beam particles' betatron oscillations in a nonlinearly coupled wakefield become resonant in the horizontal and vertical planes.

Infectious viral pathogens significantly impact wild Leporidae populations, particularly , which was listed as 'Endangered' in 2019. Myxomatosis and rabbit haemorrhagic disease are major contributors to severe epizootics with limited long-lasting immunity. This study expanded beyond these well-documented viruses to include a broader spectrum of viruses in 36 wild rabbit carcasses () collected from the field in 2018, 2019, 2021 and 2024, and 32 wild rabbits hunted in 2017/2018.

Background: Fistula-in-ano is an abnormal tunnel formation linking the anal canal with the perineum and perianal skin. Multiple imagining methods are available to evaluate it, among which magnetic resonance imaging (MRI) is the most advanced noninvasive preoperative method. However, it is limited in its visualization function.

Introduction: A main feature of CDH is lung hypoplasia and the related presentation of pulmonary hypertension and cardiac dysfunction. Multiple factors influence pulmonary status after CDH: degree of hypoplasia, ventilator-induced injury, altered growth and development of pulmonary structures, reduced diaphragm function and chest wall abnormalities. The evolution of pulmonary sequela in this population is still unclear.

Examining the co-circulation of various serotypes and finding serotypes linked to illness severity were the main objectives of this study, which sought to investigate the epidemiology and serotype distribution of dengue in Haryana, North India. The cross-sectional study, which was carried out in a tertiary care hospital between September 2021 and April 2023, enrolled participants who met WHO criteria for probable dengue fever. Blood samples underwent molecular and serological diagnostics, such as immunochromatographic testing, VIDAS® Dengue NS1 assays, and TRUPCR® Dengue Detection and serotyping kits, in addition to the collection of clinical and demographic data.
