Research ArticleOpen accessEvery word in the titlePHENOTYPING, VIRULENCE CHARACTERISTICS OF AEROMONAS SPECIES AND THE EFFECTS OF ESSENTIAL PLANT OILS AS ANTIMICROBIAL AGENTS AGAINST PATHOGENIC ISOLATES FROM DIFFERENT SOURCESAhmed M.A. Mansour, Hoda M. Zaki, Nibal A. Hassan, Nihad A.M. El-NasharAeromonas species are increasingly recognized as enteric pathogens. Faecal samples from 20 cow, 45 sheep; 60 goat and 60 camels were examined for the presence of Aeromonas species, which was also sought in the available drinking water (55 well water and 52 drinking chlorinated tap water were also examined). Aeromonas species was isolated more frequently from goats (21.7%) than from … …American Journal of Infectious Diseases, Vol. 10, Issue 1 · 18 Jan 2014 · 8,020 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIsolation of the Antimicrobial Cyclic Peptide Subtilosin a from a Gut-Associated Bacillus subtilis StrainGhislain Schyns, Claudia R. Serra, Adriano O. Henriques et al.The endospore-forming Bacillus subtilis has been used as probiotics over the last 50 years. However, little is known on how Bacillus spp act in the gut compared to other well-characterized probiotics such as lactic acid bacteria. It is believed that the competitive exclusion of pathogens results from different mode of action notably the production of antimicrobial compounds such as bacteriocins. … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 7,678 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAntimicrobial-Impregnated Discs for Prevention of Intravenous Catheter-Related InfectionsKelly R. Daniels, Christopher R. FreiProblem statement: Healthcare-associated infections are the 5th leading cause of death in the United States. Catheter-Related Bloodstream Infections (CRBSIs) comprise 14% of all healthcare-associated infections and contribute to increased mortality and financial costs. Antimicrobial-impregnated sponge discs to be used surrounding the catheter insertion site are a newer addition to the options available for the prevention of catheter-related infections. Approach: This … …American Journal of Infectious Diseases, Vol. 8, Issue 1 · 24 Feb 2012 · 8,498 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePrevalence and Distribution of Mastitis Pathogens and their Resistance against Antimicrobial Agents in Dairy Cows in JordanAzmi D. Hawari, Fawzi Al-DabbasThe primary objective of this study was to determine the aetiology of bovine mastitis in ten herds of Holstein Friesian cow in Jordan, the prevalence of mastitis pathogens in dairy cows and their resistance to selected antimicrobial agents. Milk samples were collected from 220 lactating cows to determine the clinical and subclinical mastitis by white side test and confirmed by … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,675 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAntimicrobial Susceptibility of Bovine Subclinical Mastitis and During Milk Separation Isolates and the Accompanying Hygienic PracticesSultan Farag Nagati, Safaa Khamis HassanMilk is considered one of the most perfect foods for humans and milk contains many nutrients. Subclinical mastitis has been counted as a great problem for dairy manufacture. The disease causes severe economic losses due to lower milk production, treatment costs and increased labor and milk retained for human consumption after treatment and premature culling. A cross-sectional study was conducted … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 7 Apr 2021 · 6,506 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAntimicrobial Activities of Unconventional Compounds against Some Bacteria Associated with Skin Infections in Humans, Sheep and GoatsIman Shabana, Amira El-AdlyBacterial skin infections are a common problem encountered in clinical practice and causing great economic losses for sheep and goats producers. Increasing multidrug resistance of pathogens paves the way for reconsidering alternative medicine. The present study was carried out to explore the antibacterial activities of different volumes; 5, 25, 50 and 100 µL of gold nanoparticles (NPS) and the aqueous … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 11 Jan 2016 · 8,021 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAntimicrobial Susceptibility of Bloodstream Isolates of Staphylococcus aureus: Global Results from the Tigecycline Evaluation and Surveillance Trial, 2004-2008Daniel Amsterdam, Geoffrey Coombs, Michael DowzickyProblem statement: The Tigecycline Evaluation and Surveillance Trial (TEST) commenced in 2004 to monitor the activity of tigecycline, a new glycylcycline and numerous comparators against major hospital-and community-associated pathogens. In this report we examine the efficacy of tigecycline and comparators against isolates of Staphylococcus aureus collected from blood. Approach: Almost 4000 blood-derived isolates of Staphylococcus aureus were collected from participating … …American Journal of Infectious Diseases, Vol. 6, Issue 1 · 31 Mar 2010 · 7,469 accessesView PDFCite
Review ArticleOpen accessIn the keywordsMultidrug Resistant Microorganisms (MDR) and Biofilm Producers: A Challenge for Hospital Infectious ControlDaniel Lucio, Elizabeth Proaño, Alberto Bustillos et al.Antimicrobial Resistance (AMR) now represents a major threat to contemporary health care, especially in hospitals, where repeated antimicrobial exposure selects for and facilitates the dissemination of Multidrug-Resistant (MDR) microorganisms. Biofilm growth adds another layer of persistence by increasing microbial tolerance, supporting long-term colonization of medical devices, and worsening clinical and economic outcomes. This narrative review synthesizes evidence on MDR biofilm-forming … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 12 Sep 2026 · 774 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPrevalence and Determinants of Antibiotic Use by the Elderly in Marrakech, MoroccoNaima Aoutil, Mohamed Cherkaoui, Mohamed BouskraouiAntibiotics are essential for the prevention and treatment of bacterial infections; however, their inappropriate use among elderly populations poses serious risks, including the emergence of multidrug-resistant organisms. Antimicrobial resistance has become a critical global public health challenge, with irrational antibiotic use being one of its primary drivers. In Morocco, data on antibiotic use among older adults remain scarce, particularly regarding … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 13 Apr 2026 · 1,365 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStudy of Ageratum conyzoides L. (Asteraceae) Phytochemical Composition as Quorum-sensing Inhibitors to Combat Antibiotic-resistant Bacterial InfectionsEli Compaoré, Lassané Ouedraogo, Ablassé Rouamba et al.The rise of antibiotic-resistant bacterial infections has intensified the search for plant-derived quorum-sensing (QS) inhibitors as alternative therapeutic strategies. Ageratum conyzoides L. has a long history of traditional use as an antimicrobial agent against multidrug-resistant pathogens, yet the phytochemical basis of its QS-inhibitory activity remains incompletely characterized. This study aimed to investigate the phytochemical composition of A. conyzoides and evaluate … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 3 Apr 2026 · 1,772 accessesView PDFCite
