Pioneer of Medical Mycology: In Memory of Prof. Friedrich Staib, MD, DVM

open access: yesMycoses, Volume 69, Issue 7, July 2026.
ABSTRACT At the beginning of Friedrich Staib's academic career in the 1950s, medical mycology was a young discipline in Germany. He studied veterinary and human medicine, earning two doctorates. Initially fascinated by the changes in intestinal flora caused by the newly emerging broad‐spectrum antibacterials, i.e., the selection of fungi.

Bilateral organization of the vocal control pathway in the budgerigar, Melopsittacus undulatus

open access: yes, 1981
Anatomical and electrophysiological methods were used to map the vocal control nuclei of the budgerigar, Melopsittacus undulatus. Beginning with the motor nucleus of the syrinx, nuclei were located using antidromic stimulation and then injected with ...

Comparative study of eggshell antibacterial effectivity in precocial and altricial birds using Escherichia coli.

open access: yesPLoS ONE, 2019
In this study, we compared the antibacterial effectivity of the eggs of six precocial and four altricial bird species using Escherichia coli, based on their eggshell traits. The ultrastructure of eggshell was observed using a scanning electron microscope

Genetic Characterisation and Aggressiveness of the Fusarium oxysporum Species Complex in Tomato Plants and Irrigation Water From Australian Processing Fields

open access: yesPlant Pathology, Volume 75, Issue 4, July‐August 2026.
This study reveals extensive genetic diversity within Fusarium oxysporum isolates associated with Australian processing tomato systems, showing that phylogenetic placement does not necessarily correspond with pathogenicity. ABSTRACT Fusarium oxysporum Species Complex (FOSC) includes important soil‐borne pathogens of a range of crops worldwide.

Experimental studies of social foraging in budgerigars, Melopsittacus undulatus [PDF]

open access: yes, 2015
Many animals are social foragers. Foraging with others may confer a number of advantages, but is also likely to present a number of challenges that are not encountered by solitary foragers.

Budgerigars have complex sleep structure similar to that of mammals.

open access: yesPLoS Biology, 2020
Birds and mammals share specialized forms of sleep including slow wave sleep (SWS) and rapid eye movement sleep (REM), raising the question of why and how specialized sleep evolved.

Clinical approach to small psittacines and passerines

open access: yesIn Practice, Volume 48, Issue 4, Page 181-189, May 2026.
Background: The most commonly encountered small avian species in clinical practice are psittacines, such as budgerigars, cockatiels and lovebirds, and passerines, such as finches and canaries. These birds are increasingly presented for veterinary treatment, with owners expecting a high standard of care.

A pathogenic paramyxovirus from a budgerigar (Melopsittacus undulatus)

open access: yes, 1974
An outbreak of acute enteritis with high mortality among caged budgerigars (Melopsittacus undulatus) in a bird sanctuary was investigated. An agent with the properties of a paramyxovirus, but distinct from Newcastle disease virus and myxovirus Yucaipa ...
