The mycotoxin deoxynivalenol (DON) contaminates animal feed worldwide, frequently resulting in poor performance and economic losses. Data concerning the effects on poultry health or focusing intestinal toxicity response to oxidative stress are scarce. Also, there is a need for strategies mitigate negative of DON. This study aimed investigate Lactobacillus spp. treatments intestine, liver kidney fed DON-contaminated diet. To achieve this aim, histological, morphometrical histochemical assays...
Deoxynivalenol (DON) is a predisposing factor for necrotic enteritis. This study aimed to investigate the effects of DON and Clostridium perfringens (CP) challenge on intestinal morphology, morphometry, oxidative stress, immune response broilers. Additionally, we evaluated potential Lactobacillus spp. mixture as an approach mitigate damage induced by challenge. One-day-old broiler chickens (n = 252) were divided into seven treatment groups: Control, DON, CP, CP + VL (DON viable mixture), HIL...
The extensive use of antimicrobials in broiler production is changing the bird microbiota, fostering drug-resistant bacteria, and complicating therapeutic interventions, making problem multidrug resistance global. monitoring antimicrobial virulence genes are tools that have come to assist breeding these animals, directing possible treatments as already used human medicine collecting data demonstrate dissemination multidrug-resistant strains may cause damage industry public health. This work...
The present study aimed to evaluate the prevalence of antimicrobial resistance and clonal relationships in
Salmonella spp. is one of the main agents responsible for foodborne infection in humans, and products poultry origin are most common sources. Studies have shown occurrence antimicrobials resistant animal products. The Extended Spectrum ?-Lactamase (ESBL) enzymes that confer to bacteria ability hydrolyze cephalosporin with an oximino side chain monobactams. This study aimed investigate antimicrobial resistance profile, identify phenotypes genotypes multiple drug (MDR) produce ESBL from...
Considering the worrying emergence of multidrug resistance, including in animal husbandry and especially food-producing animals, need to detect antimicrobial resistance strains poultry environments is relevant, mainly considering a One Health approach. Thus, this study aimed conduct longitudinal monitoring broiler chicken farms, with an emphasis on evaluating frequency fosfomycin β-lactams. Escherichia coli was isolated from farms (cloacal swabs, meconium, feed, water, litter, Alphitobius...
Escherichia coli is a key indicator of food hygiene, and its monitoring in meat samples points to the potential presence antimicrobial-resistant strains capable causing infections humans, encompassing resistance profiles categorized as serious threats by Centers for Disease Control Prevention (CDC), such Extended-Spectrum Beta-Lactamase (ESBL)—a problem with consequences animal, human, environmental health. The objective present work was isolate characterize ESBL-producing E. from poultry,...
Clostridium perfringens is the etiological agent of NE, a disease that greatly affects poultry industry. Experiments on induction NE are difficult to carry out, as it multifactorial disease, and thus different predisposing factors have been used. This study evaluated effect Gumboro vaccine virus (IBDV-vac) associated or not with infection by Eimeria spp. in broilers, factor for NE. Broilers (n = 99) were divided into groups (11) challenged IBDV-vac, CP type G (CP13, CP14 CP03) both. The...
Avian cellulitis causes significant losses to the poultry industry. Avian-pathogenic Escherichia coli (APEC) is etiological agent of that disease. This microorganism has zoonotic potential and may act as reservoir antimicrobial-resistance genes. In this context, production extended-spectrum B-lactamase (ESBL) one main antimicrobial resistance mechanisms. The objective study was determine ESBL in an (E. coli) strain isolated from avian lesions. Twenty-two E. Coli isolates were harvested...
After the growth-promoting antibiotics prohibition, intestinal health became an increasing concern worldwide in poultry farming. The histological evaluation is inexpensive technique that brings relevant information, but poultry, immediate process of post-mortem autolysis interferes directly on samples quality for analysis hindering a precise diagnosis. This study aimed to standardize broilers’ intestines sample collection and fixation analysis. Seven broiler chickens received standard diet...
ABSTRACT: Enterococcal spondylitis affects poultry and causes progressive lameness. This study reports what seems to be the first case of vertebral osteomyelitis caused by Enterococcus in broiler chickens southern Brazil. We also conducted an experimental infection evaluate microorganismal characteristics pathogenicity chickens. performed bacterial isolation, identification, histopathology. The isolates were tested for their growth survival capacity at different temperatures, pH values,...
Background: The ingestion of foreign bodies in parrots has already been described and associated with the curious behavior birds or stressful conditions. Foreign gastrointestinal tract are usually diagnosed through clinical signs, laboratory tests, radiographic findings historical data. metallic can lodge any segment tract, commonly found proventricle gizzard. This study investigated a case necrotizing hepatitis due to body Ara ararauna (Linnaeus, 1758).Case: An approximately 9-month-old...
