Prediction of Cross-Fitness for Adaptive Evolution to Different Environmental Conditions: Consequence of Phenotypic Dimensional Reduction [PDF]
How adaptive evolution to one environmental stress improves or suppresses adaptation to another is an important problem in evolutionary biology. For instance, in microbiology, the evolution of bacteria to be resistant to different antibiotics is a critical issue that has been investigated as cross-resistance.

Interdisciplinary Research-Based Learning in Organic Chemistry and Microbiology Laboratories: Synthesis and Biological Testing of Novel Penicillin Derivatives [PDF]
Interests in the mechanism that penicillin bestows on its target protein has driven the curiosity of its binding specificity towards the methicillin resistant strain of Staphylococcus areus, and its expression of a unique penicillin binding protein that ...

Microbiology of the Phyllosphere [PDF]
The above-ground parts of plants are normally colonized by a variety of bacteria, yeasts, and fungi. While a few microbial species can be isolated from within plant tissues, many more are recovered from the surfaces of healthy plants.

Multi-Target Tobit Models for Completing Water Quality Data [PDF]
Monitoring microbiological behaviors in water is crucial to manage public health risk from waterborne pathogens, although quantifying the concentrations of microbiological organisms in water is still challenging because concentrations of many pathogens in water samples may often be below the quantification limit, producing censoring data.

Plasmodium sporozoites require the protein B9 to invade hepatocytes
Summary: Plasmodium sporozoites are transmitted to a mammalian host during blood feeding by an infected mosquito and invade hepatocytes for initial replication of the parasite into thousands of erythrocyte-invasive merozoites.

The SAP-1 Payload: A Technology Demonstration for Space-Based Microbiology Experiments [PDF]
The SSPACE Astrobiology Payload (SAP) series, starting with the SAP-1 project is designed to conduct in-situ microbiology experiments in low earth orbit. This payload series aims to understand the behaviour of microbial organisms in space, particularly those critical for human health, and the corresponding effects due to microgravity and solar/galactic
