Elucidating shark diets with DNA metabarcoding from cloacal swabs
Molecular Ecology Resources, 2021AbstractAnimal dietary information provides the foundation for understanding trophic relationships, which is essential for ecosystem management. Yet, in marine systems, high‐resolution diet reconstruction tools are currently under‐developed. This is particularly pertinent for large marine vertebrates, for which direct foraging behaviour is difficult or

Insights into the diet and trophic ecology of white sharks (Carcharodon carcharias) gained through DNA metabarcoding analyses of cloacal swabs [PDF]
Environmental DNA, 2023 The white shark (Carcharodon carcharias) is one of the world's largest apex predators found throughout the world's temperate and subtropical marine environments.

PRESENCE AND IDENTIFICATION OF YEASTS DETECTED BY ORAL AND CLOACAL SWABS IN CAPTIVE CHELONIA FROM CENTRAL ITALY. [PDF]
, 2012 Although tortoises and turtles are currently very popular pets, so far little is known about the fungal flora carried by these reptiles. The present study was carried out to detect and identify the yeast flora living in the oro-pharynx and cloaca of captive tortoises/turtles (n. 76), reared in Central Italy.

DETECTION OF SALMONELLA IN YOUNG CHICKS WITH CLOACAL SWABS
Advanced Food and Nutritional Sciences, 2020Background: A non-destructive method such as a cloacal swab is very important to the poultry industry because it allows the breeder companies to determine if Salmonella is present in the valuable breeder chicks without the necessity of sacrificing any birds.Objective: To evaluate a nondestructive procedure to detect the presence of Salmonella in ...

Examining the hemagglutinin subtype diversity among wild duck-origin influenza A viruses using ethanol-fixed cloacal swabs and a novel RT-PCR method [PDF]
Virology, 2008 This study presents an interconnected approach for circumventing two inherent limitations associated with studies defining the natural history of influenza A viruses in wild birds.

Absence of sexual dimorphism makes it difficult to determine bird’s sex. A number of both invasive and noninvasive methods as a DNA template of sampling for avian sexing can be used. The aim of this study was to compare the efficacy of different sources of DNA for avian sexing by PCR. Samples were collected from dried blood spots, buccal swabs, cloacal

Cloacal swabs were examined using a peroxidase-antiperoxidase (PAP) method that employs a monoclonal antibody to chlamydiae. The specificity and sensitivity of cloacal-swab PAP examination and the prevalence of chlamydiosis were calculated using both culture and tissue PAP evaluation as standards.

Chicken parvovirus (ChPV) has been associated with malabsorption syndrome (MAS) in broilers. However, the participation of this virus in such syndrome is unclear, since it may be detected in diseased and healthy chickens. In the course of these studies, it was argued whether ChPV genome loads might be correlated to the occurrence of MAS.
