The poisonous bacteria: Pseudomonas aeruginosa

By Nitara Wijayatilake Pseudomonas aeruginosa is an opportunistic pathogen, taking advantage of existing infections to cause extreme detriment to immune-suppressed individuals. With respect to its classification, it is a gram-negative alpha-proteobacteria and 10% of its genome is made up of regulatory genes, influencing its highly adaptable nature. This bacteria has a wide host range but researchContinue reading “The poisonous bacteria: Pseudomonas aeruginosa”

How the gut microbiota affects neurological disorders: An Insight into Parkinson’s Disease

By Yuki Agarwala Our gut is home to approximately 100 trillion bacteria, both good and bad, which are collectively known as the gut microbiota (Can gut bacteria, 2016). This represents 10 times the number of cells in the human body, and a stunning 3 million genes. Interestingly, only around 1~3% of these bacteria are commonContinue reading “How the gut microbiota affects neurological disorders: An Insight into Parkinson’s Disease”

Which Diets make the Gut Happiest?

By Katherine Bethell It is widely accepted that diet has a strong correlation with health and disease.  A healthy diet which is considered high in fibre, reduces the risk of inflammatory diseases such as asthma whilst also lowering the likelihood of cardiovascular and respiratory diseases (Thorburn A et al., 2014). Diet has a large impactContinue reading “Which Diets make the Gut Happiest?”

Parthenogenesis: The phenomenon of virgin birth

By Isabelle Hall The phenomenon of parthenogenesis, also known as ‘virgin birth’ (from the Greek – parthenos, meaning “virgin”, and genesis, meaning “birth” or “origin”), refers to the development of an embryo without fertilisation. This is considered to be another form of asexual reproduction, which includes processes such as binary fission and budding (Dudgeon etContinue reading “Parthenogenesis: The phenomenon of virgin birth”

BAX, a new target for cancer therapy?

By Themis Halka Cancer remains in today’s society a great challenge for scientists, doctors and patients. Even though numerous cancers can be treated with relatively good outcomes via surgery (radiotherapy and chemotherapy), these techniques are not miraculous and come with important side effects. Intensive research targets the development of new ways to treat cancer, usingContinue reading “BAX, a new target for cancer therapy?”

How Are Antivirals used in Influenza Virus Infection?

By Yuchen Lin Influenza virus infection, commonly known as the flu, is a widespread respiratory disease. There are four types of influenza viruses: Type A, B, C, and D. The first three types have the ability of human-infection, whilst Type D viral infection has not yet been detected in humans but is well known toContinue reading “How Are Antivirals used in Influenza Virus Infection?”

Could Caesarean births be responsible for childhood allergies?

By Katherine Bethell  In the last several decades the number of births by caesarean section has increased dramatically to approximately 30% of all deliveries (Bager P et al., 2008). Whilst this rate has been increasing, so has the incidence of allergic diseases including food allergy, eczema, allergic rhinitis and asthma (Bjorksten B, 2004). It hasContinue reading “Could Caesarean births be responsible for childhood allergies?”

The Gut Microbiota and its Impact on Human Health

By Tanjim Sayeeda Our bodies are inhabited by trillions of microorganisms ranging from archaea, protozoa, single-celled eukaryotes and viruses (Eloe-Fadrosh & Rasko, 2013). These microscopic organisms, termed microbiota, outnumber human cells 10 to 1 and are extremely rich in their diversity (Sender, Fuchs & Milo, 2016). They form various relationships with their hosts, such asContinue reading “The Gut Microbiota and its Impact on Human Health”

How tiny microorganisms lead to big changes: the role of the microbiome in obesity

By Ellie Fung In the midst of the current pandemic, it is easy to forget about the trillion other microbial species that thrive within humans apart from COVID-19. But what if a subset of these microbes has the potential to elevate the severity and fatality of coronavirus infections by contributing to obesity (Sanchis-Gomar et al.,Continue reading “How tiny microorganisms lead to big changes: the role of the microbiome in obesity”
