Firmicutes

OTUs richness and calculated estimates, the farming soil is the most diverse in the soil sites included in this study. The predominance of nifH OTUs related to proteobacteria and the nonappearance of nifH gene sequence related to Cyanobacteria, Firmicutes and Archaea have also been described from some previous studies (Coelho et al. 2009; Lovell et al. 2001; Jenkins et al. 2004; Tai et at. 2013; Tai et at. 2014;…

Every year one in six Americans get food poisoning . Food poisoning occurs due to the contamination of food through microorganisms. Botulism is a form of food poisoning caused by the microorganism Clostridium botulinum. Clostridium botulinum is a gram-positive bacterium, bacillus in shape, and is an obligate anaerobe.1 The bacterium can produce endospores, making it resistant to microbial control methods. Clostridium botulinum survives in nonliving reservoirs1 . It is commonly found in soil and…

Impetigo is the most common bacterial infection in children. This is a highly contagious infection of the superficial layers of the epidermis and is primarily caused by Streptococcus pyogenes or Staphylococcus aureus (1).

The most common form of impetigo is called Impetigo contagiosa. This type usually starts as a red sore on your…

The variability of the human gut microbiome and its effect on health Abstract The human gut microbiome consists of a wide range of microbes such as bacteria, fungi and archaea which can be found in the gastrointestinal tract. This gut microbiome can have both beneficial and harmful effects on the host. On one hand, it is involved in processes such as modulation of the immune system and metabolism which are beneficial for the human host. On the other hand, an imbalance in the gut microbiome…

A review of Methanoculleus: a hydrogenotrophic methanogens frequently observed in anaerobic habitats Summary: Keywords: Methanoculleus, hydrogenotrophic pathway, methane production Introduction: Methane is an important greenhouse gas due to its capability of retaining heat and its release from many nature sources, including wetlands, fresh water or sea water sediments, and animal manure, etc. There are two main means of atmospheric methane production, biogenic and abiogenic. Since 70%-80% of…
