Many bacterial pathogens are becoming drug resistant faster than we can develop new antimicrobials. To address this threat in public health, a metamodel antimicrobial cocktail optimization (MACO) scheme is demonstrated for rapid screening of potent antibiotic cocktails using uropathogenic clinical isolates as model systems. With the MACO scheme, only 18 parallel trials were required to determin...

background: acute bacterial meningitis is among serious infections of the central nervous system (cns). the early diagnosis and empiric antibiotic treatments have led to a reduction in morbidity and mortality rates. pcr and the enzymatic digestion of 16s rdna fragment following the pcr by universal primers led up fast and sensitive determination. the aims of the present study was to improve our...

Enterotoxigenic Escherichia coli K99 is one of the dominant pathogens associated with diarrhea of calves. Immunoglobulin Y (IgY), has been used as an inexpensive alternative to antibiotics for the prevention and therapy of several bacterial infections. The study aimed to prepare IgY antibodies against E. coli K99 and to investigate its in vitro effectiveness. E. c...

Abstract Keeping health and nutritional value of the packed foods has a great value in food industries. Among the diverse methods of food processing and packaging, vacuum packaging is one of the best methods for a variety of food products, such as fish. In order to evaluate the effectiveness of such method in preventing of bacterial growth during preservation of fish fillets, four vacuum p...

Background Bronchoscopic valve implantation is an established treatment in selected patients with severe lung emphysema. There is evidence in literature of increased bacterial colonization of various implants. So far, it is unclear if an increased bacterial colonization can also be observed after endoscopic valve therapy. Methods Retrospective analysis of patients with examination of the bron...

Introduction:  Nowadays  the  medical,  therapeutic  and  pharmacological  application  of  magnetic  fields  (MF)  and  its  biological  effect  has  raised  question  about  the  safety  of  MF.  This  study  aimed  at  scrutinizing the effect of static MF on the resistance of S. aureus to antibiotic.  Materials and Methods: This prospective, case–control study was conducted to evaluate the e...

BACKGROUND Smoking is a leading cause of respiratory infections worldwide. Tobacco particulate matter disrupts iron homeostasis in the lungs and increases the iron content in the airways of smokers. The airway epithelia secrete lactoferrin to quench iron required for bacteria to proliferate and cause lung infections. We hypothesized that smokers would have increased bacterial growth and biofilm...
