Robert Koch, Creation, and the Specificity of Germs [PDF]

open access: yes, 2010
Microbiology is dominated by evolution today. Just look at any text, journal article, or the topics presented at professional scientific meetings. Darwin is dominant. Microbiology is dominated by evolution today.

Optimisation of freeze substitution protocols for the examination of malaria parasite structure by volumetric electron microscopy

open access: yesJournal of Microscopy, EarlyView.
Abstract Malaria is one of the deadliest infectious diseases in the world, annually responsible for over 400,000 deaths. It is caused by parasites of the genus Plasmodium, which undergo remarkable structural changes during their development within different cells across various hosts.

Evolution of malaria virulence in cross-generation transmission through selective immune pressure [PDF]

open access: yes, 2007
Theoretical arguments and some mathematical models of host-parasite coevolution (e.g. [1- 6]) suggest host immunity as the driving source for the evolution of parasite virulence.

Traction force generation in Plasmodium sporozoites is modulated by a surface adhesin

open access: yesJournal of Microscopy, EarlyView.
Abstract Plasmodium sporozoites are the highly polarised and motile forms of the malaria parasite transmitted by mosquitoes to the vertebrate hosts. Sporozoites use myosin motors to generate retrograde flow of actin filaments. These are linked to plasma membrane spanning adhesins, which in turn bind to the extracellular environment, resulting in ...

Comparative attraction of Anopheles quadriannulatus and Anopheles arabiensis to humans estimated by comparing their relative abundance in samples of mosquito larvae and adults collected across an ecologically heterogeneous landscape in southern Tanzania Utafiti wa kulinganisha mvuto wa mbu aina ya Anopheles arabiensis na Anopheles quadriannulatus kwa binadamu katika mandhari yenye mazingira mbalimbali kusini mwa Tanzania

open access: yesMedical and Veterinary Entomology, EarlyView.
Light and barrier traps near human activity selectively captured more Anopheles arabiensis, indicating a strong attraction to humans and explicit bias in adult sampling methods. Traps placed in open glades away from humans captured species proportions similar to larval samples, suggesting reduced sampling bias in those settings. Visits by entomological

Extended time to maturity in Anopheles coluzzii: Implications of late egg hatch for vector control and transgene fitness

open access: yesMedical and Veterinary Entomology, EarlyView.
The fitness of Anopheles coluzzii mosquito lines (VK strain) selected for early and late egg hatching was compared with each other and a reference strain (Mopti). There was an observed increase in fitness in fecundity and survival among the late‐hatching lines, but no negative effects of selection on fecundity and adult survival were detected.

Slime mould computes planar shapes [PDF]

open access: yes, 2011
Computing a polygon defining a set of planar points is a classical problem of modern computational geometry. In laboratory experiments we demonstrate that a concave hull, a connected alpha-shape without holes, of a finite planar set is approximated by ...

Modelling vector and host distributions to inform potential disease risk: A case study of West Nile virus in the United Kingdom

open access: yesMedical and Veterinary Entomology, EarlyView.
Correlative modelling approaches can be used successfully to predict the distribution of vectors and hosts involved in vector‐borne diseases of concern. For West Nile virus in the United Kingdom, host distributions are unlikely to be a significant factor influencing change. Vector distributions and urbanisation will drive increasing risk. Projecting to

Towards Malaria Elimination: A Nationwide Case–Control Study to Assess Risk Factors for Severe Malaria‐Related Deaths in Brazil

open access: yesTropical Medicine &International Health, EarlyView.
ABSTRACT Objective The objective of this study is to describe malaria‐related deaths and assess their risk factors. Methods This is a case–control study using data from Brazil's Ministry of Health (2011–2020) on malaria‐related deaths (ICD‐10: B50‐B54). A probabilistic record linkage was performed to match epidemiological data (Sivep‐Malaria and Sinan)
