Detecting Campylobacter coli in young chicks using two different cloacal swab techniques

Journal of Applied Poultry Research, 2018
SUMMARY It is important to determine whether valuable broiler-breeder chicks are contaminated with Campylobacter. It is important to have a non-destructive method to determine whether microorganisms such as Campylobacter are present without sacrificing the animal.

Chlamydia avium‐associated hepatitis in a fancy pigeon (Columba livia f. domestica)

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract A 5‐year‐old, male, fancy pigeon (Columba livia f. domestica, 380 g), found dead without prior clinical signs, was submitted for diagnostic postmortem examination. Histologically, the animal exhibited heterophilic to mononuclear hepatitis consistent with avian chlamydiosis; however, Chlamydia psittaci‐specific real‐time polymerase chain ...

Integumentary fibrosarcoma in a free‐living swan (Cygnus olor): Medical and welfare considerations

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract A 10‐kg adult male mute swan (Cygnus olor) of unknown age was admitted for investigations of two large ventral masses overlying the keel bone, which were discharging purulent material. The masses measured 8.9 × 2.1 cm and 4.2 × 3.2 cm. Empirical treatment with non‐steroidal anti‐inflammatory drugs and antimicrobials was instigated.

Ophidiomycosis Prevalence and Disease Ecology in a Natrix tessellata (Laurenti, 1768) Population From Northern Italy

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 3, Page 292-305, April 2026.
ABSTRACT Fungal pathogens pose a growing threat to vertebrate biodiversity. In snakes, Ophidiomyces ophidiicola (Oo) has garnered particular concern, although its impact in Europe remains poorly understood. We conducted a season‐long, standardized survey of dice snakes (Natrix tessellata) along the northern shore of Lake Como (Italy) to quantify Oo and
