Diverse hosts, diverse immune systems: Evolutionary variation in bat immunology

open access: yesAnnals of the New York Academy of Sciences, EarlyView.
Bats are recognized to have distinct immune systems from other vertebrates that may allow them to host virulent pathogens without showing disease. However, these flying mammals are also incredibly diverse, such that bats should not be expected to be immunologically homogenous.

Photodynamic therapy of cancer‐associated infections

open access: yesPhotochemistry and Photobiology, EarlyView.
Pathogens can be involved in tumor initiation, promotion and progression through different mechanisms, and their treatment can prevent new cancer cases, improve outcomes, and revert poor‐prognostic phenotypes. Photodynamic therapy (PDT) successfully treats different types of cancers and infections, and, therefore, has a unique potential to address ...

Enhanced fluorescence emission or singlet oxygen production of cationic porphyrazines and porphyrins through combination with carbon dots

open access: yesPhotochemistry and Photobiology, EarlyView.
A cationic free‐base porphyrin and porphyrazine and their zinc(II) complexes were combined to carbon dots (CD). The macrocycles strongly interact with the nanoparticles, quenching the CD fluorescence and enhancing the fluorescence emission efficiency of a porphyrazine by 140% and the singlet oxygen production of a porphyrin by 70%.

Physiological ecology of the ciliated protozoon Loxodes [PDF]

open access: yes, 1986
Loxodes faces special problems in living close to the oxic-anoxic boundary. In tightly-stratified ponds like Priest Pot its optimum environment may be quite narrow and it can be displaced by the slightest turbulence.

Studies on the growth, viability, and lipids of Streptococcus bovis : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science [PDF]

open access: yes, 1966
In their comprehensive review of rumen metabolism, Annison and Lewis (1959) emphasised the symbiotic relationship between the metabolic activities of the mixed population of anaerobic bacteria and ciliated protozoa, and the digestion of fodder consumed ...

The oral microbiota and periodontal health in orthodontic patients

open access: yesPeriodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.

Epidemiology and Molecular Characterization of Entamoeba spp. in Non-Human Primates in Zoos in China

open access: yesVeterinary Sciences
The genus Entamoeba infects both humans and NHPs. In zoos, visitors feeding significantly increases the frequency of human-to-NHP contact, thereby raising the risk of zoonotic transmission.
