Abstract Infectious bronchitis (IB) is one of the avian diseases with the greatest impact on poultry farming worldwide. In Brazil, strain BR-I (GI-11) is the most prevalent in poultry flocks. The present study aimed to develop a seminested RT-PCR assay specific for the diagnosis of BR-I IBV in Brazilian samples, targeting subunit 1 of the S gene. The detection limit of this assay was 10 copies of the IBV genome. In this study, 62.24% of 572 organ pools from the 5 regions of Brazil tested positiv...

ABSTRACT This report describes the genome sequences of four Salmonella enterica subsp. enterica serovar Gallinarum ( Salmonella Gallinarum) strains isolated in Colombia in 2017 from layer breeders of different ages. The layer breeder flocks were presenting with an elevated mortality with lesions typical of fowl typhoid (FT). These draft genome sequences revealed a highly conserved genome of Salmonella Gallinarum strains circulating in Colombia.

Abstract Heat stress has a relevant effect on animal health and productivity. Stress and environmental changes can contribute to disease development, such as avian necrotic enteritis (NE). The goal of this study was to analyze the effects of heat stress applied to broiler chickens in an experimental model of co-infection with Clostridium perfringens and Eimeria spp. Therefore, the current study was designed to analyze the effect of heat stress to broiler chickens in an experimental model of infe...

Abstract Information on the dynamics of the chicken immune system during bacterial or parasite challenge in the presence or absence of stressful situations may provide a better understanding of the complex mechanisms behind these diseases. Necrotic enteritis (NE) had been controlled previously by the proper use of antimicrobial agents; however, more recently, NE has reemerged in many countries. The imposed restrictions on antimicrobial use and/or the intensive productive programs implemented by ...

Avian bornaviruses (ABVs) are the causative agents of proventricular dilatation disease (PDD), a fatal neurologic disease considered to be a major threat to psittacine bird populations. We performed a reverse transcription PCR survey to detect the presence of canary avian bornavirus (CnBV) in birds of order Passeriformes related to different clinical manifestations, such as sudden death, neurologic signs, apathy, anorexia, excessive beak growth, and PDD. A total of 227 samples from captive and w...

Heat stress has been related to the impairment of behavioral and immunological parameters in broiler chickens. However, the literature is not clear on the involvement of neuroimmune interactions in a heat stress situation associated with bacterial and parasitic infections. The present study evaluated the production of monoamines and their metabolites in brain regions (rostral pallium, hypothalamus, brain stem, and midbrain) in broiler chickens submitted to chronic heat stress and/or infection an...
