Staphylococcus aureus is often the cause of various diseases and food poisoning in animals humans. Avocado seeds ( Persea americana , Mill) contain important compounds that have antimicrobial activity. This study aimed to observe hematological dynamics mice Mus musculus domesticus ) infected with S. induced by P. extract. BALB/c male aged 12 weeks were divided into 6 groups 5 each group, named ...

Vibrio vulnificus infection has attracted special interest because of its high mortality rate. However, the identification of its major pathogenic determinant still remains obscure. In this study, a cytolysin-negative mutant strain of V. vulnificus CVD707 was used to determine the role of phospholipase A (PLA) in the pathogenesis of this bacterial infection. The mutant strain caused the lysis o...

In addition to their anti-bacterial action, tetracyclines also have complex biological effects, including the modification of mitochondrial protein synthesis, metabolism and gene-expression. Long-term clinical studies have been performed using tetracyclines, without significant side effects. Previous studies demonstrated that doxycycline (DOX), a major tetracyclin antibiotic, exerted a protecti...

BACKGROUND AND OBJECTIVES Cholera is an endemic diarrheal disease in Iran, caused by Vibrio Cholerae. The epidemiology, transmission route, environmental determinants and antimicrobial resistant pattern of cholera have been changed during recent years. In this study the epidemiology and antimicrobial resistance of cholera in Iran during 2013 outbreak was investigated. MATERIALS AND METHODS A ...

Exposure of normal mouse fibroblasts (MEF3T3) to ionizing radiation (IR) resulted in a dose-dependent increase of mTOR mRNA and protein levels and the shuttling of the mTOR protein from its normal, predominantly mitochondrial location to the cell nucleus. The same IR doses that activated mTOR induced the phosphorylation of p53 on Ser(18) (mouse equivalent to human Ser(15)) and the subsequent tr...

Enterococcus lactis IW5 was obtained from human gut and the potential probiotic characteristics of this organism were then evaluated. Results showed that this strain was highly resistant to low pH and high bile salt and adhered strongly to Caco-2 human epithelial colorectal cell lines. The supernatant of E. lactis IW5 strongly inhibited the growth of several pathogenic bacteria and decreased th...

In accordance with epidemic COVID-19, the elevated infection rates, disinfectant overuse and antibiotic misuse what led to immune suppression in most of population addition genotypic phenotypic alterations microorganisms, so a great need reevaluate genetic determinants that responsible for bacterial community (biofilm) has been raised. A total 250 clinical specimens were obtained from patients ...

Mít (Artocarpus heterophyllus) là loại cây ăn trái ít kén đất, dễ trồng. Diện tích trồng mít tại Việt Nam ngày càng mở rộng. Hiện nay do quy trình canh tác, bảo vệ thực vật chưa đảm các yêu cầu kỹ thuật nên diện tích mít xuất hiện nhiều bệnh, phổ biến như bệnh xơ đen, nứt thân xì mủ và thối nhũn trái v.v… Bệnh được xác định vi khuẩn Dickeya dandatii gây ra, mạnh trong mùa mưa tỉnh Hậu Giang một...
