Slaughterhouse Survey on the Frequency of Pathologies Found in Bovine Post-mortem Inspections

The aim was to reveal the prevalence of post-mortem lesions in two large-scale bovine slaughterhouses found in Romania so as to point out the potential hazards for human health. The proper examination of animal carcasses and organs that are destined for human consumption is essential in order to ensure food safety but not all the time properly made due to lack of time during the process of slaughter. The results showed that the most frequent lesions found within the examined organs were caused by parasitic infestation (Echinococcus granulosus; Dyctiocaulus viviparus) and the highest prevalence was found in the lungs. The pathology of lesions found in bovine organs is very variable in the slaughterhouse, being able to report strange aspects such an ectopic liver in the lung parenchyma. Measures should be taken in the farms due to this high prevalence of parasites which causes both health problems as well as economical losses

Ascites Syndrome Associated with Hypothyroidism in a Brahma Chicken: a Case Study and Review of the Literature

Ascites syndrome (AS) in chickens represents a major cause of mortality and the most frequent metabolic-related cause of abattoir carcass condemnation in broilers. Susceptibility of broiler chickens to ascites is determined by a complex interaction between genetically-controlled factors (as high-rate metabolism and peculiarity of the cardiovascular system) and exogenous factors such as nutrition, and temperature. Endocrine imbalances, especially thyroid-gland dysfunctions, are currently regarded as key-elements in the development of AS. The current case represents the first spontaneous case of hypothyroidism (goiter) associated with AS in broilers, bringing additional arguments to the theory which claims the role of thyroid dysfunction in this syndrome. Further studies of spontaneous cases which must include assessment of the thyroid hormones need be performed in order to better understand the link between thyroid gland dysfunction and the cardiopulmonary changes in the context of AS in birds

How Reliable Are Laboratory Test When Diagnosing Bitch Mastitis?

Canine mastitis represents a major threat for both pups and nursing bitch. If left untreated, it can complicate with neonatal death, sepsis, and mastitis gangrenosa; for this reason quick and accurate diagnosis and treatment initiation are crucial health restoration. Even though mastitis is considered to be an emergency, most of the time it is overlooked. Henceforth, clinicians should be aware of the clinical importance of mastitis and that laboratory assays such as milk pH, cytology, and biochemistry (milk and serum) are of high utility. Furthermore, milk microbiology and susceptibility tests are still important since they bring additional information about the pathogenesis and the treatment possibilities

Canine granulomatous meningoencephalitis: a case report and review of the literature

Canine granulomatous meningoencephalomyelitis (GME) is a subtype of a large group of idiopathic central nervous system diseases with a relatively high incidence (up to 25%) among dogs with central nervous system affection (Tipold, 1995). Neurological presentation of GME can vary from focal to multifocal, or ocular form. Histologically, GME is characterized by focal, disseminated or perivascular mononuclear cells spreading in the white matter and meninges (Coates and Jeffery, 2014). The aim of the current case report is to describe the pathological findings and to discuss the diagnostic features of this disease. Therefore, we should further emphasize the importance of this disease in current veterinary practice

Comprehensive behavioral and biochemical outcomes of novel murine models of GM1-gangliosidosis and Morquio syndrome type B

Deficiencies in the lysosomal hydrolase β-galactosidase (β-gal) lead to two distinct diseases: the skeletal disease Morquio syndrome type B, and the neurodegenerative disease GM1-gangliosidosis. Utilizing CRISPR-Cas9 genome editing, the mouse β-gal encoding gene, Glb1, was targeted to generate both models of β-gal deficiency in a single experiment. For Morquio syndrome type B, the common human missense mutation W273L (position 274 in mice) was introduced into the Glb1 gene (Glb

Clinically Considerations About Induced Experimental Periodontitis in Rats Treated by Photodynamic Therapy

Periodontitis is a chronic inflammatory condition that affects the soft and hard tissue supporting the tooth, favoring the adhesion of bacteria that can generate dental laxity and bone resorption. This study aimed to test an experimental protocol for inducing periodontitis which allows a close clinical assessment and to evaluate the effectiveness of a photodynamic therapy (PDT) protocol to reverse the associated clinical signs. Fifteen Wistar male rats were used for this study, divided into three equal groups. Tooth scaling, rooting and planning of the first superior left molar were performed in all rats, causing the displacement of the gingiva in order to create an accumulation of plaque. A 5-0 cotton ligature was placed, provoking an inflammatory response removed after ten days. One group received one session of PDT; another group received 3 PDT; the last one represented the control group, with no treatment. Clinical evaluation was represented by assessing the body weight, mobility index and bleeding. A rat grimace scale was used to determine the pain. The results showed clinical aspects of periodontitis and healing tissue proved microscopically. The tested procedure can provide all the key biological factors present in periodontal disease and an option for reversing the clinical aspects

Helicobacter Pylori-Induced Gastric Infections: From Pathogenesis to Novel Therapeutic Approaches Using Silver Nanoparticles

Helicobacter pylori is the first formally recognized bacterial carcinogen and the most important single digestive pathogen responsible for the induction of gastroduodenal diseases such as gastritis, peptic ulcer, and, finally, gastric neoplasia. The recently reported high rates of antimicrobial drug resistance hamper the current therapies of H. pylori, with therapeutic failure reaching up to 40% of patients. In this context, new treatment options and strategies are urgently needed, but the successful development of these new therapeutic tools is conditioned by the understanding of the high adaptability of H. pylori to the gastric acidic environment and the complex pathogenic mechanism. Due to several advantages, including good antibacterial efficiency, possible targeted delivery, and long tissular persistence, silver nanoparticles (AgNPs) offer the opportunity of exploring new strategies to improve the H. pylori therapy. A new paradigm in the therapy of H. pylori gastric infections using AgNPs has the potential to overcome the current medical limitations imposed by the H. pylori drug resistance, which is reported for most of the current organic antibiotics employed in the classical therapies. This manuscript provides an extensive overview of the pathology of H. pylori-induced gastritis, gastric cancer, and extradigestive diseases and highlights the possible benefits and limitations of employing AgNPs in the therapeutic strategies against H. pylori infections
