Dose-dependent effects of a glyphosate commercial formulation - Roundup UltraMax - on the early zebrafish embryogenesis.

The use of herbicides with glyphosate as an active ingredient, the so-called glyphosate-based herbicides (GBH), has increased dramatically in recent years currently being the most widely used in the world. Therefore, glyphosate residues have been detected in water and soils near the application sites. Recent studies indicate that GBH may cause adverse effects on vertebrates although these have been attributed to the presence of adjuvants in the commercial formulations rather than to the sole compound.

Phagolysosomal activity of macrophages in Nile tilapia (Oreochromis niloticus) infected in vitro by Aeromonas hydrophila: Infection and immunotherapy.

The biochemical mechanisms involved in phagocytosis and the intracellular survival of Aeromonas hydrophila (Ah) in host macrophages (MΦs) are complex processes that affect infection success or failure. Thus, in the present study, we described the in vitro infection of Nile tilapia MΦs by a homologous bacterium and tested the effects of anti-A. hydrophila immunoglobulin Y (IgY) on the phagolysosomal activity and intracellular survival of the pathogen.

Recent advances on Dirofilaria repens in dogs and humans in Europe.

Toll-like receptor 9 gene in Periodontal Disease - A promising biomarker.

Periodontal Disease is an infectious and inflammatory disorder triggered mainly by periodontopathogenic bacteria, however, as a multifactorial disease, several factors modulate its progression, namely, genetic factors. Toll-like receptors (TLR) recognize molecular patterns present in pathogens and trigger an immune response against them. Thus, sequences variants in TLR genes seem to have the potential to modify the predisposition to Periodontal Disease and its progression.

Meat quality of Santa Inês lamb chilled-then-frozen storage up to 12 months.

Frozen lamb meat storage is widely used to extend its shelf life. However, it is scarcely known whether this practice changes the quality of lamb meat. The aim of this study was to evaluate the meat quality at five frozen storage periods (0, 3, 6, 9, and 12 months after slaughter) of 30 Santa Inês male lambs (hair sheep) finished in feedlot.

This report describes a 6-year-old, female, cross-breed dog presented with signs of 90 days duration and diagnosed with a mass located in the right nasal cavity.

Biodentine for Furcation Perforation Repair: An Animal Study with Histological, Radiographic and Micro-Computed Tomographic Assessment.

Introduction: Biodentine has been scarcely studied as a furcation perforation (FP) repair material, mostly by methodologies. This animal study aimed to compare the histological responses, radiographic, and micro-computed tomographic (micro-CT) outcomes after FP repair with Biodentine or ProRoot MTA (MTA) in dogs' teeth.

Methods And Materials: Fifty teeth from five dogs were divided into 4 groups: MTA (=20, FP repaired with ProRoot MTA), BDT (=20, FP repaired with Biodentine), PC (=5, positive control, FP without repair) and NC (=5, negative control, without perforation).

MS-222 short exposure induces developmental and behavioural alterations in zebrafish embryos.

MS-222 has been widely used as an anaesthetic in fish, thus, raising the need to infer about its toxicological safety during development. In this study, MS-222 toxicity in zebrafish embryos was evaluated after a 20-min exposure at different stages of development. Embryos exposed during the 256-cell stage displayed an increase in mortality, associated with defective early developmental pathways.

Thelazia callipaeda affects a range of mammal species, including humans, and in the last two decades has been reported in multiple European countries, being classified as an emergent vector-borne pathogen. In Portugal T.

Dirofilaria immitis and Angiostrongylus vasorum: The current situation of two major canine heartworms in Portugal.

Cardiopulmonary nematodes are life-threatening pet parasites increasingly reported throughout Europe, with overlapping endemic areas. Dirofilaria immitis is a mosquito-borne whilst Angiostrongylus vasorum is a snail-borne pathogen. Both adult nematodes reside in the pulmonary arteries and right cardiac ventricle of domestic and wild canids, causing a wide spectrum of clinical presentations ranging from cough, dyspnoea and exercise intolerance to severe vascular and pulmonary disease with hearth failure that may lead to death.

Awareness of zoonotic diseases and parasite control practices: a survey of dog and cat owners in Qatar.

Background: Qatar is one of the wealthiest and fastest growing economies in the world, experiencing a rapid increase in human and pet populations. Given the paucity of data on prophylactic measures against endo- and ectoparasites of pets in Qatar, as well as on the owners' awareness of zoonotic diseases, a questionnaire was conducted.

Methods: From July to November 2017, 150 multiple-choice questionnaires were administered to dog and/or cat owners who attended two veterinary clinics in Doha.

Exercise training protects against cancer-induced cardiac remodeling in an animal model of urothelial carcinoma.

Limiting cancer-induced cardiac damage has become an increasingly important issue to improve survival rates and quality of life. Exercise training has been shown to reduce cardiovascular complications in several diseases; however, its therapeutic role against cardiovascular consequences of cancer is in its infancy. In order to add new insights on the potential therapeutic effect of exercise training on cancer-related cardiac dysfunction, we used an animal model of urothelial carcinoma submitted to 13 weeks of treadmill exercise after 20 weeks of exposure to the carcinogenic N-butyl-N-(4-hydroxybutyl)-nitrosamine (BBN).

Ketamine induction of p53-dependent apoptosis and oxidative stress in zebrafish (Danio rerio) embryos.

Ketamine is a widely used pharmaceutical that has been detected in water sources worldwide. Zebrafish embryos were used in this study to investigate the oxidative stress and apoptotic signals following a 24h exposure to different ketamine concentrations (0, 50, 70 and 90 mg L). Early blastula embryos (∼2 h post fertilisation-hpf) were exposed for 24 h and analysed at 8 and 26 hpf.

Validation of IgY for the diagnosis of Streptococcus agalactiae-caused endocarditis and bacterial meningitis in Nile tilapia (Oreochromis niloticus).

Streptococcus agalactiae (Sta), which belongs to Lancefield group B, causes sepsis, endocarditis and bacterial meningitis in human neonates and Nile tilapia. Because the pathophysiology of Sta infection is partially similar in both species, the identification of biomarkers for the diagnosis and study of this disease is of importance for human and animal health. Therefore, in the present study, we produced an immunoglobulin Y (IgY) by immunizing laying hens with Sta proteins and evaluated its ability to detect Sta in paraffinized tilapia brain and cardiac tissue by direct immunofluorescence (IMF) and indirect immunohistochemistry (IHC).
