1. Effects of route of inoculation on Mycoplasma gallisepticum infection in captive house finches

Author:
Dhondt, K.V.; Dhondt, A.A.; Ley, D.H.

Subject:
chickens; conjunctivitis; Fringillidae; mycoplasmosis; disease outbreaks; disease transmission; feces; dietary exposure; wild birds; Mycoplasma gallisepticum; seroconversion; disease severity; immune response; conjunctiva; disease course
Abstract:
... The routes by which Mycoplasma gallisepticum initiates infection during outbreaks of conjunctivitis in house finches remain uncertain. As M. gallisepticum recovered from the cloaca of chickens remains viable for up to 3 days in chicken faeces, the possibility of spread via faecal contamination has been suggested. To test the hypothesis that food or water contaminated with M. gallisepticum may init ...

Abstract:
... Cell and cytokine responses during the development of foot pad dermatitis (FPD) in growing turkeys were studied in a model system. The objective was to evaluate the hypothesis that FPD is an allergic response to the environmental materials. Hybrid female turkeys at 28 days of age were exposed to wet litter for 48 h in a randomized block experiment. Expression levels of pro-inflammatory (interleuki ...

... Salmonella enterica serovar Gallinarum (S. Gallinarum) is the causative agent of fowl typhoid, a severe systemic disease of chickens that results in high mortality. In this study we re-evaluated the ability of live S. Gallinarum 9R vaccine to protect from wild-type S. Gallinarum challenge. In laboratory trials, there was a significant difference between the vaccinated and unvaccinated control grou ...

Abstract:
... Liver samples of psittacine birds with a histological suspicion of an adenovirus infection, confirmed by electron microscopy examination, were subjected to virus isolation attempts using a heterologous cell culture system and a homologous cell culture system in the form of chicken embryo liver cells and psittacine embryo fibroblasts, respectively. Whereas isolation in chicken embryo liver cells fa ...

Abstract:
... We previously developed a real-time polymerase chain reaction (PCR) assay for absolute quantitation of serotype 1 Marek's disease virus in feather tips of chickens, and this has been used clinically to monitor a flock's response following vaccination with CVI988, an attenuated serotype 1 strain. The level of vaccine virus in feather tips associated with protection against challenge by virulent vir ...

Abstract:
... Tibial dyschondroplasia is a skeletal abnormality characterized by an avascular plug of cartilage in the metaphysis of the long bones of rapidly growing birds. An avascular, thickened growth plate also occurs in vitamin D/calcium-deficient rickets. This research was conducted to evaluate tibial dyschondroplasia and rachitic tissue for factors shown to be important in normal growth plate vasculariz ...

Abstract:
... This report describes a keratoacanthoma causing abnormal maxillary beak growth in a 6-year-old male budgerigar (Melopsittacus undulates). Although the bird was still capable of eating, it had recently been demonstrating signs of respiratory distress and euthanasia was recommended. On histological examination, the neoplasm was dramatically effacing the normal structure of the maxilla and infiltrati ...

birds; bird diseases; Mycoplasma gallisepticum; Mycoplasma synoviae; hosts; host-pathogen relationships; cell membranes; bacterial antigens; phenotype; microbial colonization; mycoplasmosis; phenotypic variation; pathogenesis; disease diagnosis; diagnostic techniques
Abstract:
... The interactions between avian mycoplasmas and their host cells are far more complex than might be anticipated from their apparent structural and functional simplicity. Phenotypic diversity in the form of reversible phase variation, antigenic variation or size variation is an adaptive mechanism that enables avian mycoplasmas to survive in a hostile and highly evolved host. Despite significant simi ...
