Introduction: Industrial livestock farming is a possible source of multi-resistant Gram-negative bacteria, including producers extended spectrum beta-lactamases (ESBLs) conferring resistance to 3rd generation cephalosporins. Limited information currently available on the situation ESBL in outside Western Europe. A surveillance study was conducted from January May 2014 four dairy cattle farms different areas Nile delta, Egypt. Materials and Methods: In total, 266 samples were collected 4...

Infected laying hens regularly excrete large amounts of Campylobacter jejuni with their feces, which represent a reservoir infection within the flock and for animals in region. However, knowledge about survival times C. these feces is still scarce. Therefore, orienting laboratory experiments were carried out under controlled conditions to estimate both artificially naturally contaminated hen feces. In 6 different flocks (3 Campylobacter-free 3 Campylobacter-positive flocks), fresh excreta...

BACKGROUND: Systematic screening for TB using automated chest radiography (ACR) with computer-aided detection software (CAD4TB) has been implemented at scale in Karachi, Pakistan. Despite evidence supporting the use of ACR as a pre-screen prior to Xpert ® MTB/RIF diagnostic testing presumptive patients, there no data published on its mass real-world settings. METHOD: Screening was undertaken mobile digital X-ray vehicles hospital facilities and community camps. Chest X-rays were offered...

The popularity of food produced from animals kept under an organic regimen has increased in recent years. In Germany, turkey meat consumption increased. Despite several studies assessing the susceptibility campylobacters to various antibiotics poultry, no sufficient data exists regarding antimicrobial resistance organic-reared turkeys. This study provides information about antibiotic Campylobacter isolated turkeys reared on farms Germany. Ninety-six strains (41 C. jejuni and 55 coli) were...

A loop-mediated isothermal amplification (LAMP) assay system was established, allowing rplD gene-based simultaneous detection of Campylobacter jejuni and coli in enriched meat products. Additionally, one-step differentiation target species on agar plates enabled by cdtC gene- gyrA duplex LAMP. Both the – LAMP assays amplified sequences all 62 C. 27 strains used for determining inclusivity revealed 100% exclusivity toward 85 tested non-target species. Throughout entire experiments, were...

Introduction Intravenous thrombolysis with tissue plasminogen activator (tPA) and endovascular therapy (ET) represent the cornerstone of modern stroke management. Despite advancements in these therapies, a subset patients fails to achieve optimal recanalization (TICI 2b‐3), which is associated poor functional outcomes higher mortality rates. As result, there has been growing interest adjunctive pharmacologic interventions that could enhance efficacy ET. The safety tirofiban as an adjunct ET...
