“…The analysis of bacterial isolates from pus showed the predominance of Enterobacterales isolates, particularly E. coli , followed by Staphylococcus spp. Enterobacterales, and E. coli especially have been found to be major players in the formation of abscesses in animals [ 5 , 26 , 27 ], although several studies have isolated S. aureus from abscesses as the quintessential suppurative pathogen in large proportions [ 13 , 14 , 28 , 29 ]. These bacterial species isolated are zoonotic pathogens, which places public health at risk.…”

Abscesses represent the most prominent emerging problem in the red meat industry, leading to great economic constraints and public health hazards. Data on etiological agents present in these purulent lesions in Algeria are very scarce. The aim of this study was to identify the bacteria responsible for these abscesses and to determine their antibiotic susceptibility profiles. A total of 123 samples of abscesses from 100 slaughtered sheep and 23 slaughtered cattle were cultured in several media. A total of 114 bacterial isolates were cultured from 103 abscesses. Bacteria were identified using MALDI–TOF, and antibiotic susceptibility was determined by the disk diffusion method on Mueller–Hinton agar. A total of 73.6% (n = 84) corresponded to Enterobacterales, of which four were multidrug-resistant (MDR). These isolates, together with Staphylococcus aureus, coagulase negative Staphylococci, and seven randomly chosen susceptible Escherichia coli isolates, were further characterized using WGS. Resistome analysis of the four MDR Enterobacterales isolates revealed the presence of OXA-48 carbapenemase in two Klebsiella pneumoniae ST985 and one E. coli ST10 isolates and a CTX-M-15 ESBL in one E. coli isolate ST1706. Two coagulase-negative Staphylococci isolates were found to carry the mecA gene. WGS showed the presence of different resistance genes and virulence genes. Our study revealed 5% of MDR Enterobacterales (including ESBLs and carbapenemases) identified from abscesses, thus urging the need for abscess monitoring in slaughterhouses.

“…Viruses in the Retroviridae family (retroviruses) are characterized by their single-stranded RNA nucleic information dependent on DNA polymerase for their retroviral replication [ 110 ]. Further classification can be made into two subfamilies, Orthoretrovirinae and Spumaretrovirinae, and seven genera [ 111 ].…”

Surveillance of viral pathogens in both point-of-care and clinical settings is imperative to preventing the widespread propagation of disease—undetected viral outbreaks can pose dire health risks on a large scale. Thus, portable, accessible, and reliable biosensors are necessary for proactive measures. Polymeric microparticles have recently gained popularity for their size, surface area, and versatility, which make them ideal biosensing tools. This review cataloged recent investigations on polymeric microparticle-based detection platforms across eight virus families. These microparticles were used as labels for detection (often with fluorescent microparticles) and for capturing viruses for isolation or purification (often with magnetic microparticles). We also categorized all methods by the characteristics, materials, conjugated receptors, and size of microparticles. Current approaches were compared, addressing strengths and weaknesses in the context of virus detection. In-depth analyses were conducted for each virus family, categorizing whether the polymeric microparticles were used as labels, for capturing, or both. We also summarized the types of receptors conjugated to polymeric microparticles for each virus family.

“…The isolation rate of dermatophytes was relatively high in the spring and winter for dogs, and in the spring, summer and autumn for cats in western Turkey [26]. These pathogenic fungi flourish well at an estimated 25-28 °C temperature [28,29]. Large and crowded populations cause easy exposure to the infection.…”

This article focuses on performing clinical, laboratory examination, isolation, and identification of Microsporum spp., general and biochemical analyzes of the blood of spontaneously infected animals and the successful treatment of Microsporum spp. infection in cats and dogs using miconazole/chlorhexidine combination and itraconazole. Skin scraping, hair samples and blood samples were collected from a total of 132 animals. Out of 132 examined dogs and cats, 43 animals were diagnosed with the disease, 28 of the sick animals were cats and 15 were dogs. Based on the results of RBCs (Red Blood Cell) Count, HGB (Hemoglobin), HCT (Hematocrit), MCH (Mean Corpuscular Hemoglobin) blood tests and MCHC (Mean Corpuscular Hemoglobin Concentration), low levels of healthy red blood cells, hemoglobin, and low results in MCHC blood tests were observed in the blood of all of infected dogs and cats, a high level of AST (Aspartate Aminotransferase) is also observed in some infected animals. Among the sick animals, there were also animals with normal AST (Aspartate Aminotransferase) levels. In our study, 29 infected cats and dogs were treated with itraconazole and one of two topical therapies including 2% chlorhexidine and 2% miconazole shampoo (VetWELL Micoseb Medicated Shampoo for Dogs & Cats - Medicated Dog Shampoo with Miconazole, Chlorhexidine & Aloe for Skin Infection Treatment of Skin Conditions 12oz). This study aimed to perform clinical characteristics, laboratory examination, isolation and identification of zoophilic dermatophytes due to Microsporum spp. In addition, to evaluate general and biochemical analyses of the blood of spontaneously infected pets and stray and shelter animals with Microsporum spp. in Baku and Ganja cities in Azerbaijan, and to focus the treatment includes systemic and topical therapy.
