AVIAN CHOLERA IN COMMON CROWS, Corvus brachyrhynchos, FROM THE CENTRAL TEXAS PANHANDLE [PDF]

open access: yesJournal of Wildlife Diseases, 1981
An epornitic of avian cholera involving approximately 150 birds is described from a flock of common crows, Corvus brachyrhynchos, on a single playa lake utilized as a roost in Castro County, Texas, during early spring of 1980. There was a concomitant epornitic of avian cholera involving several hundred ducks and geese of several species on adjacent ...

Inventory of wildlife use of mortality pits as feeding sites: implications of pathogen exposure

open access: yesHuman-Wildlife Interactions, 2017
To better understand the use of mortality pits by wildlife and possible pathogen dissemination from the resulting wildlife contact in these areas, we used 8 camera traps on 4 mortality pits in Colorado from June to December 2014 to create a species ...

Patterns of evolution of MHC class II genes of crows (Corvus) suggest trans-species polymorphism [PDF]

open access: yesPeerJ, 2015
A distinguishing characteristic of genes that code for the major histocompatibility complex (MHC) is that alleles often share more similarity between, rather than within species.

Crow Deaths as a Sentinel Surveillance System for West Nile Virus in the Northeastern United States, 1999

open access: yesEmerging Infectious Diseases, 2001
In addition to human encephalitis and meningitis cases, the West Nile (WN) virus outbreak in the summer and fall of 1999 in New York State resulted in bird deaths in New York, New Jersey, and Connecticut. From August to December 1999, 295 dead birds were

Pathogenicity assessment of Shiga toxin-producing Escherichia coli strains isolated from wild birds in a major agricultural region in California

open access: yesFrontiers in Microbiology, 2023
Shiga toxin-producing Escherichia coli (STEC) consists of diverse strains differing in genetic make-up and virulence potential. To better understand the pathogenicity potential of STEC carried by the wildlife, three STEC and one E.

Mosquito blood-feeding patterns and nesting behavior of American crows, an amplifying host of West Nile virus

open access: yesParasites & Vectors, 2021
Background Although American crows are a key indicator species for West Nile virus (WNV) and mount among the highest viremias reported for any host, the importance of crows in the WNV transmission cycle has been called into question because of their ...

Operant responding in the common crow (Corvus brachyrhynchos) [PDF]

open access: yesBulletin of the Psychonomic Society, 1973
Common crows can be shaped to keypeck for food reinforcement, using conventional operant conditioning apparatus. They will respond for a variety of foods, but live mealworms and Prime dog food are the most effective of those studied here. The crow would appear to be an interesting avian species for study, because it possesses a number of more complex ...

West Nile and St. Louis encephalitis viral genetic determinants of avian host competence. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2018
West Nile virus (WNV) and St. Louis encephalitis (SLEV) virus are enzootically maintained in North America in cycles involving the same mosquito vectors and similar avian hosts.

Experimental Infection of North American Birds with the New York 1999 Strain of West Nile Virus

open access: yesEmerging Infectious Diseases, 2003
To evaluate transmission dynamics, we exposed 25 bird species to West Nile virus (WNV) by infectious mosquito bite. We monitored viremia titers, clinical outcome, WNV shedding (cloacal and oral), seroconversion, virus persistence in organs, and ...
