Interest in the pathogenesis, detection, and prevention of viral infections has increased broadly many fields research over past year. The development water treatment technology to combat infection by inactivation or disinfection might play a key role places where drinking sources are biologically contaminated. Laser-induced graphene (LIG) antimicrobial antifouling surface effects mainly becaus...

to determine the prevalence of bacterial mastitis in cattle, milk samples positive for california mastitistest (cmt) were cultured during a period of almost 4 years. the bacterial species isolated from 2904 milksamples studied were coagulase negative staphylococcus sp. in 879 (30.27%) samples, streptococcusagalactiae in 642 (22.11%), s. dysgalactiae in 332 (11.43%), e. coli in 295 (10.16%), sta...

Introduction: Aloe Vera compounds have inhibitory activity on fungi, bacteria, and viruses. This study examines the antibacterial activity of A. Vera purified extracts including gel, boiled skin, boiled gel, and distilled extract against pathogenic bacteria, Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), Klebsiella pneumonia and Pseudomonas aeruginosa were elucidated. Method: Th...

INTRODUCTION Periodontal disease is an inflammatory condition caused by periodontal microorganisms. Viruses such as human cytomegalovirus (HCMV) and Epstein-Barr virus (EBV) are associated with certain types of periodontal disease, but their roles in promoting the disease are unclear. Because both viruses infect human macrophages, cells which play key roles in the clearance of pathogenic bacter...

background: masske is a traditional iranian butter made from yoghurt. the first aim of this study was to isolate and identify the nonlactic pathogenic microflora by culture and molecular methods of identification, and the second purpose was to identify genetic similarity of the isolated bacteria in masske. materials and methods: in order to detect pathogenic dominant indicator microorganisms, a...

Respiratory infectious diseases are mainly caused by viruses or bacteria that often interact with one another. Although their presence is a prerequisite for subsequent infections, viruses and bacteria may be present in the nasopharynx without causing any respiratory symptoms. The upper respiratory tract hosts a vast range of commensals and potential pathogenic bacteria, which form a complex mic...

conclusion according to our findings, it is recommended to use ferula gummosa extract, as a herbal alternative treatment, in more investigations to prove its treatment effects on infections. objective ferula gummosa grows as a native plant in different parts of iran and has been used for treatment of some infections such as uti since ancient times. present study is planned to show the antibacte...

aim :  the aim of this study was to investigate the in vitro inhibitory effect of probiotic e.coli nissle 1917 (ecn) strain against pathogenic bacteria isolated from patients with diarrhea. background : probiotics are viable microorganisms that are shown to have beneficial effects on human health. ecn is a typical example of probiotics; however, there are few reports of it being administered fo...

Periodontitis is one of the most complex infectious diseases of the human body. Individual periodontal lesions may harbor millions of genomic copies of herpesviruses (179) as well as papillomaviruses, human immunodeficiency virus (HIV), human T-lymphotropic virus type 1, torquetenovirus, and hepatitis B and C viruses (190). Herpesvirus-infected periodontal sites tend to exhibit more breakdown t...

Abstract Our oral cavity houses various types of microbes including bacteria, protozoa, fungi and viruses, harboring over 700 bacterial species. Oral dysbiosis refers to the imbalance between symbionts pathobionts in cavity, posing potential threats host cardiovascular health. Importantly, promotes pathophysiology through different mechanisms. Although overgrowth certain pathogenic bacteria hav...
