Anaerobic digestion process is one of the alternative methods to convert organic waste into methane gas which is a fuel and energy source. Activities of various kinds of microorganisms are the main factor for anaerobic digestion which produces methane gas. Therefore, in this study a modified Anaerobic Baffled Reactor (ABR) with working volume of 50 liters was designed to identify the microorgan...

Generally, the cause of aspiration pneumonia is polymicrobial, including fungi and aerobic and anaerobic bacteria, but Aspergil...

Purulent pericarditis is one of the most common causes of cardiac tamponade and if left untreated has a mortality of 100%. Staphylococcus aureus and Streptococcus pneumonia have been implicated as the main etiology of purulent pericardial effusion followed by fungi and anaerobic sources. Actinomyces odontolyticus pericardial involvement has been reported in the literature only once. To our know...

Wound infections are one of the most common hospital acquired infections and are an important cause of morbidity and account for 70-80% mortality (Gottrup et al., 2005; Wilson et al., 2004). Wound infections can be caused by different groups of microorganisms like bacteria, fungi and protozoa. However, different microorganisms can exist in polymicrobial communities especially in the margins of ...

Bacteriological failure with penicillin that has been used widely for years in group A beta hemolytic streptococcal (GABHS) tonsillopharyngitis is being reported as high as 30%. Because of this unresponsiveness, many different agents are being used as alternative options. We evaluated the effect of clarithromycin, amoxicillin/clavulanate (CAM), cefprozil and benzathine penicillin G (Pen G) on t...
