They are also used to evaluate the pharmacokinetics, toxicity, and efficacy of new drug candidates, helping to identify the most promising therapies before they enter human clinical trials.

Antimicrobial drug resistance (AMR) is one of the most pressing threats to global health, posing a serious challenge to the effective treatment of infectious diseases. AMR occurs when microorganisms—such as bacteria, viruses, fungi, and parasites—evolve mechanisms to resist the drugs that once killed or inhibited them. This resistance is accelerated by the overuse and misuse of antibiotics, antifungals, and other antimicrobial agents in human medicine, agriculture, and veterinary care. As resistant pathogens become more widespread, infections that were once easily treatable are becoming increasingly difficult to manage, leading to longer hospital stays, higher medical costs, and increased mortality.The global rise of AMR has been fueled by several factors. One of the primary drivers is the excessive use of antibiotics in both human healthcare and agriculture, where antibiotics are often used to prevent infections rather than treat them. This indiscriminate use creates selective pressure on pathogens, encouraging the development of resistance. In many parts of the world, poor infection control measures, inadequate sanitation, and limited access to quality healthcare further exacerbate the spread of resistant infections. Additionally, the widespread use of antibiotics in animals for growth promotion and disease prevention contributes to the emergence of resistant bacteria that can be transmitted to humans through the food supply.

Microbial diagnostics in low-resource settings are essential for improving the diagnosis, treatment, and control of infectious diseases, particularly in areas where healthcare infrastructure, laboratory facilities, and access to advanced technologies are limited. In these settings, timely and accurate diagnosis of infectious diseases is often challenging due to constraints such as a lack of trained personnel, expensive diagnostic tools, and the absence of proper diagnostic laboratories. As a result, many individuals in low-resource environments suffer from delayed or incorrect diagnoses, leading to worsened health outcomes, the spread of infections, and increased mortality.

The impact of climate change on infectious diseases is an increasingly important area of study as global temperatures rise, weather patterns shift, and extreme weather events become more frequent. These environmental changes are influencing the spread, emergence, and transmission of infectious diseases, creating new public health challenges and exacerbating existing ones. Climate change affects infectious diseases in multiple ways, from altering ecosystems and the habitats of pathogens and vectors to influencing human behavior and the availability of healthcare resources.One of the most significant ways that climate change impacts infectious diseases is by altering the distribution of disease vectors, such as mosquitoes, ticks, and fleas, which transmit diseases like malaria, dengue, Zika virus, Lyme disease, and West Nile virus. Rising temperatures and changing precipitation patterns can expand the geographic range of these vectors into areas that were previously inhospitable. For example, warmer temperatures can allow mosquitoes to survive at higher altitudes or latitudes, bringing diseases like malaria and dengue fever to regions that have not traditionally experienced them. Similarly, the expansion of tick populations due to milder winters has led to an increase in Lyme disease in areas that were previously not endemic to the disease.

Anticancer microbial therapies are an emerging field of research that explores the potential of microorganisms to treat cancer.
