The spreading of mycotoxic nephropathy in animals/humans was studied. The possible etiological causes provoking this nephropathy were carefully reviewed and analyzed. The natural content of the most frequent nephrotoxic mycotoxins in target feedstuffs/foods were investigated, in addition to their significance for development of renal damages in endemic areas. An estimation of the level of exposure of humans to the nephrotoxic mycotoxin, ochratoxin A (OTA), is made. The possible synergism or additive effects between some target mycotoxins in the development of nephropathy is also covered...

The combined toxicities of binary mixtures of veterinary pharmaceuticals active compounds (PhACs) were examined using the bioluminescent bacterium Aliivibrio fischeri as a test organism (Microtox® test). Mixtures were prepared at an equitoxic ratio that corresponded to the IC10 of individual PhACs. In addition, we determined the toxicity of a multi-component mixture that contained all of the investigated PhACs mixed at the ratio corresponding to their individual values of Predicted No Effect Concentrations (PNEC)...

One Health is a collaborative, transdisciplinary effort working locally, nationally, and globally to improve health for people, animals, plants, and the environment. The term is relatively new (from ∼2003), and it is increasingly common to see One Health included by name in interinstitutional research partnerships, conferences, communications, and organizational frameworks, particularly those championed by the human health and veterinary medical communities. Environmental quality is arguably the least developed component within the One Health framework, but can be guided by expertise within the Society of Environmental Toxicology and Chemistry (SETAC)...

Avermectins (AVMs) are used worldwide in agriculture and veterinary medicine. Residues of avermectin drugs, causing toxicological effects on non-target organisms, have raised great concern. The aim of this study was to investigate the effects of AVM on the expression levels of alpha synuclein (α-Syn) and proteasomal activity in pigeon (Columba livia) neurons both in vivo and in vitro. The results showed that, the mRNA and protein levels of α-Syn increased in AVM treated groups relative to control groups in the cerebrum, cerebellum and optic lobe in vivo...

Fipronil (FIP) is widely used across the world as a broad-spectrum phenylpyrazole insecticide and veterinary drug. FIP was the insecticide to act by targeting the γ-aminobutyric acid (GABA) receptor and has favorable selective toxicity towards insects rather than mammals. However, because of accidental exposure, incorrect use of FIP or widespread FIP use leading to the contamination of water and soil, there is increasing evidence that FIP could cause a variety of toxic effects on animals and humans, such as neurotoxic, hepatotoxic, nephrotoxic, reproductive, and cytotoxic effects on vertebrate and invertebrates...

Animal cruelty is a known behavior of psychopaths, and although the serial killing of humans is widely acknowledged worldwide, this type of crime against animals is seldom discussed. This report describes the necropsy and toxicological findings of 37 dogs and cats, which were found dead in plastic bags in Sao Paulo, Brazil. The animals had all been in the care of an alleged animal rescuer and were to be referred for adoption before being found dead. In the necropsy, the animals showed varying degrees of putrefaction, indicating different periods of death, as well as single or multiple perforations on the thorax...

BACKGROUND: MicroRNAs (miRNA) are ~19-25 nucleotide long RNA molecules that fine tune gene expression through the inhibition of translation or degradation of the mRNA through incorporation into the RNA induced silencing complex (RISC). MicroRNAs are stable in the serum and plasma, are detectable in a wide variety of body fluids, are conserved across veterinary species and humans and are expressed in a tissue specific manner. They can be detected at low concentrations in circulation in animals and humans, generating interest in the utilization of miRNAs as serum and/or plasma based biomarkers of tissue injury...

The detection of antibiotics in water systems has instigated great environmental concern due to the toxicological effects associated with these compounds. Their discharge into the environment results from the ubiquity of use in medical, veterinary, and agricultural practices. Some of the effects of antibiotics include development of antibiotic-resistant bacteria, making it difficult to treat diseases, variation in natural microbial communities, and enzyme activities. In this study, the first comprehensive survey of some frequently used antibiotics namely ampicillin (AMP), amoxicillin (AMX), sulfamethoxazole (SMX), chloramphenicol (CAP), and ciprofloxacin (CPF) within Lake Victoria Basin of Kenya is presented...

BACKGROUND: Adulteration of drugs of abuse may be done to increase profits. Some adulterants are relatively innocuous and others result in significant toxicity. Clenbuterol is a β2-adrenergic agonist with veterinary uses that has not been approved by the U.S. Food and Drug Administration for human use. It is an infrequently reported heroin adulterant. We describe a cluster of hospitalized patients with laboratory-confirmed clenbuterol exposure resulting in serious clinical effects. CASE SERIES: Ten patients presented with unexpected symptoms shortly after heroin use...

This study aimed to quantify the environmental fate of antimicrobials applied in Fenneropenaeus chinensis aquaculture production in China and to assess their potential risks for surrounding aquatic ecosystems, for the promotion of antimicrobial resistance in target and non-target bacteria and for consumers eating shrimp products that contain antimicrobial residues. For this, we first used the results of an environmental monitoring study performed with the antimicrobial sulfamethazine to parameterize and calibrate the ERA-AQUA model, a mass balance model suited to perform risk assessments of veterinary medicines applied in aquaculture ponds...

Veterinary pathologists working in diagnostic laboratories are sometimes presented with cases involving animal poisonings that become the object of criminal or civil litigation. Forensic veterinary toxicology cases can include cases involving animal cruelty (malicious poisoning), regulatory issues (eg, contamination of the food supply), insurance litigation, or poisoning of wildlife. An understanding of the appropriate approach to these types of cases, including proper sample collection, handling, and transport, is essential so that chain of custody rules are followed and proper samples are obtained for toxicological analysis...

This review provides a tutorial for individuals interested in quantitative veterinary pharmacology and toxicology and offers a basis for establishing guidelines for physiologically based pharmacokinetic (PBPK) model development and application in veterinary medicine. This is important as the application of PBPK modeling in veterinary medicine has evolved over the past two decades. PBPK models can be used to predict drug tissue residues and withdrawal times in food-producing animals, to estimate chemical concentrations at the site of action and target organ toxicity to aid risk assessment of environmental contaminants and/or drugs in both domestic animals and wildlife, as well as to help design therapeutic regimens for veterinary drugs...

Due to the possible toxicological impact, the accumulation of pharmaceuticals in wildlife as a consequence of human practices is of growing concern. The consumption of carrion at feeding stations - the so-called 'vulture restaurants' - with no management of the veterinary drugs it contains may expose scavengers to pharmaceuticals. To demonstrate this, we analyzed plasma from Eurasian griffon vultures (Gyps fulvus) originating from two different areas of Spain for antibiotics such as enrofloxacin and ciprofloxacin, its primary metabolite...

Exhumation is required for the investigation of suspicions deaths when a body is buried and is usually performed under court order. Exhumation of animals is not a routine practice in forensic pathology. In this study, 30 male 70-day-old Wistar rats were experimentally exposed to the carbamate pesticides aldicarb and carbofuran. Toxicological, macroscopic and microscopic examinations were performed. Groups of 3 animals (2 exposed and 1 control) were evaluated at 24h, 3days, 5days, 7days and 10days post-mortem...

Ketamine (KT) is used to induce and maintain general anaesthesia in combination with sedative drugs in human and animals. Because of its dissociative and hallucinogenic effects, KT has become a recreational drug in a variety of social settings and may be included in the panel of drugs of abuse that are controlled in driving under the influence (DUI) ascertainment. In a local driving license re-granting protocol, a case where a veterinary physician was found positive to KT and nor-ketamine (NK) in hair suggested the possibility of a professional exposure in a veterinary setting and prompted an experimental study...
