AI Article Synopsis

  • The report highlights a case of toxicosis in beef cattle herds in Sicily, Italy, where outbreaks occurred after grazing on contaminated winter pasture.
  • Affected cattle, primarily between 6 to 36 months old, exhibited symptoms like anorexia, weight loss, and increased urination, leading to a mean morbidity of 29% and mortality of 21%.
  • Clinical findings included severe urinary bladder distention and various blood abnormalities, with necropsy revealing significant lesions affecting the urinary system and liver, marking it as the first documented case of this type of poisoning in Italian cattle.

Article Abstract

Toxicity related to consumption of has been described in ruminants in some countries. This report describes the clinical and pathological findings of toxicosis in 3 beef cattle herds located in 2 different areas of Sicily, Italy. Outbreaks were observed after grazing in poor winter pasture where was abundant. Mean morbidity and mortality were 29% and 21%, respectively. Most of the affected animals (6 to 36 months old) showed anorexia, weight loss, and pollakiuria culminating in recumbency and death. Occasionally, abortion and neurological signs were observed. In animals with acute signs, there was a moderate decrease of sodium and chloride concentrations in serum. Animals with chronic signs showed an increase of serum urea, creatine phosphokinase (CPK), aspartate transaminase (AST), lactate dehydrogenase (LDH), and phosphorus and a decrease in total serum protein, calcium, chloride, and magnesium concentrations. Moderate anemia and slight neutropenia, lymphocytosis, and eosinophilia were detected in all groups. At necropsy, the main lesion was severe distention of the urinary bladder with turbid hemorrhagic urine and crystalluria. Histologically, chronic cystitis, interstitial nephritis, eosinophilic enteritis, and nonsuppurative necrotizing hepatitis were observed. To our knowledge, this is the first report of toxicosis in cattle in Italy.

The residual concentration of pesticides and heavy metals (arsenic, mercury, selenium, lead, cadmium, and aluminum) was measured in the soil and the cattle egret (Bubulcus ibis) liver from two localities at Sharkia Governorate, Egypt. The pesticide residues have taken the following pattern: chlorpyrifos > metalaxyl > piperonyl butoxide > thiophanate-methyl, in the soil. The residual concentration of pesticides was greater in the soil at Kafr El-Ashraf village (agricultural site) than at El-Qanayat city (garbage site) during the summer season of 2021 compared with the winter season of 2022.

Surra and Dourine are widespread diseases caused by two protozoan parasites Trypanosoma brucei evansi and Trypanosoma brucei equiperdum, respectively. A wide range of animals including camels, horses, cattle and buffaloes are susceptible to infection. These diseases pose a significant socio-economic burden, primarily due to the limited therapeutic options and the complications associated with toxicity and drug resistance, making disease management particularly challenging.

  • Neurofilament light chain (Nf-L) is identified as a potential biomarker for diagnosing neurological disorders in cattle, paralleling its established role in human neurology.
  • The study found that Nf-L levels varied significantly between healthy and sick cattle, with consistent median levels detected in serum and cerebrospinal fluid (CSF) across different age groups.
  • There is a promising association between Nf-L levels in serum and CSF, particularly in cattle with neurological disorders, indicating that Nf-L could serve as a valuable diagnostic tool in veterinary practices.

Babesia bigemina is an apicomplexan parasite responsible for causing "Texas fever" in bovines. Current treatments for bovine babesiosis are hindered by several limitations, including toxicity, insufficient efficacy in eliminating the parasite, and the potential for resistance development. A promising approach to overcome these challenges is the identification of compounds that specifically target essential metabolic pathways unique to the parasite.
