Symmetric dimethylarginine correlates with the urea, creatinine, potassium, and clinical scores in feline urethral obstructions.

Background: A urethral obstruction (UO) is an emergency commonly observed in male cats, which can result in significant clinical and laboratory alterations, leading to complications and death.

Objectives: This study aimed to correlate symmetric dimethylarginine (SDMA) with the urea, creatinine, potassium, and bicarbonate levels in cats with UO. In addition, the correlation between clinical score and time of obstruction was evaluated.

Research Note: The effects of a Lactobacillus helveticus ATCC 15009-derived postbiotic mitigating Salmonella Gallinarum colonization in commercial layer chicks.

This study aimed to assess the effects of a Lactobacillus helveticus ATCC 15009-derived postbiotic in mitigating experimental Salmonella Gallinarum infection. For this purpose, a sample of Lactobacillus sp. was inoculated in 2 different media, each containing different postbiotics (sensitized and nonsensitized).

Bacterial communication between Lactobacillus spp. isolated from poultry in the inhibition of Salmonella Heidelberg-proof of concept.

Bacterial communication has become an increasingly studied topic aiming at the discovery of new products to aid the treatment of diseases for which conventional options do not work. The production of safe foods, free of pathogens, has been receiving increasing attention due to market demands for food products of high quality and free of residues. This study assessed the communication between Lactobacillus spp.

Massive attack of honeybee on macaws (Ara ararauna and Ara chloropterus) in Brazil - A case report.

Three adult birds of the species Ara chloropterus and five of the species Ara ararauna from a conservation breeding facility suffered a massive attack by honeybees. The A. chloropterus birds presented swollen puncture lesions with stingers (mainly in the facial regions without feathers), swelling of the eyelids and subcutaneous tissue, and respiratory distress, and they were treated with intramuscular injections of 1.

Bacteriophage use to control Salmonella biofilm on surfaces present in chicken slaughterhouses.

Foodborne diseases represent a major risk to public health worldwide. Pathogenic bacteria can live in the form of biofilm within the food industry, providing a permanent source of contamination. The aim of this study was to evaluate the influence of the types of adhesion surfaces on Salmonella biofilm formation at eight different times, and analyze the action time of a bacteriophage pool on established biofilms.

First record of Paratanaisia bragai (Digenea: Eucotylidae) in blue and gold macaw (Ara ararauna).

The aim of this study was to provide the first report on a new host for the digenean Paratanaisia bragai in the caninde macaw Ara ararauna along with the pathological aspects of the infection in the new host. The microscopic findings revealed the presence of granulomatous interstitial nephritis. This study contributes towards knowledge of parasitism by P.

Immunomodulatory activity and control of Salmonella Enteritidis colonization in the intestinal tract of chickens by Lactobacillus based probiotic.

Lactobacillus-based probiotics (LBP) are used as competitive exclusion to control pathogenic enterobacterial infections and improve the weight gain in broiler chickens. This study assessed the inhibition of Salmonella Enteritidis (SE) infection in one-week-old broiler chicks, using an experimental LBP containing four Lactobacillus strains isolated from chickens (L. acidophilus, L.

Identification and adhesion profile of Lactobacillus spp. strains isolated from poultry.

In the aviculture industry, the use of Lactobacillus spp. as a probiotic has been shown to be frequent and satisfactory, both in improving bird production indexes and in protecting intestine against colonization by pathogenic bacteria. Adhesion is an important characteristic in selecting Lactobacillus probiotic strains since it impedes its immediate elimination to enable its beneficial action in the host.

New record of Pelecitus sp. (Nematoda, Onchocercidae) as a parasite of Athene cunicularia (Strigiformes, Strigidae) in southeastern Brazil.

The aim of this study was to report the burrowing owl Athene cunicularia as a new host for the filarid nematode Pelecitus sp. in southeastern Brazil for the first time, as well as reporting the occurrence of this nematode species in the body cavity, near the cervical air sac and lung region. This study contributes towards knowledge of parasitism in Brazilian wild birds and an anatomical region of the host as an infection site for Pelecitus sp.

Bacteriophage-induced reduction in Salmonella Enteritidis counts in the crop of broiler chickens undergoing preslaughter feed withdrawal.

Salmonella food poisoning is a public health problem. Feed withdrawal from broiler chickens before slaughter can favor the multiplication of Salmonella in the cecum and crop of contaminated animals and subsequently lead to contamination of carcasses in the processing plant. In the present study, a cocktail of lytic bacteriophages isolated from sewage water was orally administered to 45-d-old broiler chickens 1 h after they received an oral dose of 10(7) cfu/mL Salmonella enterica subspecies enterica serotype Enteritidis.

A simple method for enema administration in one-day-old broiler chicks.

The present study aimed to describe a simple technique for enema administration in one-day-old broiler chicks. For this purpose we used 455 unsexed health birds divided into four groups submitted to three different experimental protocols: in the first one, we measured the total length of the large intestine in order to establish a secure distance for probe introduction; in the second, we evaluated maximum compliance of large intestine and diffusion range; finally, based on results obtained we tested the hypothesis in 400 birds in order to standardize the method. Enema solutions applied in an intrarectal manner with a stainless steel gavage BD-10 probe into one-day-old broiler chicks at 0.

Isolation of Salmonella enterica serovar Enteritidis in blue-fronted Amazon parrot (Amazona aestiva).

Avian salmonellosis is a disease caused by bacteria of the genus Salmonella that can cause three distinct diseases in birds: pullorum diseases, fowl typhoid, and paratyphoid infection. Various wildlife species are susceptible to infections by Salmonella, regardless of whether they live in captivity or freely in the wild. The present study verified the presence of Salmonella enterica serovar Enteritidis in three captive specimens of Amazona aestiva.

Use of cecal microflora cultured under aerobic or anaerobic conditions in the control of experimental infection of chicks with Salmonella Enteritidis.

One-day-old broiler chicks received cecal microflora (CM) cultured under aerobic, anaerobic conditions, or both (mixed) and were then infected with Salmonella Enteritidis, in order to compare the efficacy of these different types of culture in terms of the number of chicks infected, cecal colonization and faecal excretion of the challenging bacteria. Regardless of culture type, CM always led to a smaller number of S. Enteritidis for any of the parameters studied compared to untreated chicks.
