This study aimed to investigate the prevalence of mycotic mastitis with special reference to Candida albicans in Holstein-Friesian dairy cows from some farms in Menoufia province, Egypt. For the study, 150 milk samples (n = 150, 20 from healthy cows and 130 from cows with subclinical and clinical mastitis) were collected from 15 smallholder dairy farms located in three localities (Quesina, Elbagour, and Shibin El-Kom) five farms from each. The samples were subjected to mycological culture and subsequently verified using traditional morphological and biochemical tests to confirm fungal characteristics followed by antimycotic susceptibility testing using Vitec 2 system. Finally, molecular identification was carried out via PCR and phylogenetic analysis. 27 samples out of 130 were positive for fungal culture representing (20.77%). Candida species were recorded the highest percentage (62.96%) of the detected fungi (17/27). In addition, C. albicans was the predominant species (3/27), which corresponds to 11.11%. Antifungal susceptibility testing of the fungal isolates showed the highest susceptibility to micafungin, followed by caspofungin (88.88% and 86.19%, respectively). However, the lowest susceptibility was noted against amphotericin B (50.55%). The three isolates of C. albicans were confirmed by PCR by amplifying the ITS region, which was then sequenced for phylogenetic analysis. The sequences have been deposited in GenBank under the following accession numbers: OR97266, OR97267, and OR97268.

Ten stray male dogs diagnosed with oligozoospermia were included in the study. The dogs were randomly assigned to two groups: Group I, the control group (n = 5), which received no treatment, and Group II, the PRP group (n = 5), which received a single intra-testicular injection of 0.5 mL of autologous PRP into each testicle. Testicular hemodynamics, hormonal and biochemical analysis and semen parameters were assessed for both groups and the examination was extended to 8 weeks.

Conversely, the values of Resistance Index (RI) and Pulsatility Index (PI) showed a significant decrease (P < 0.001) in group II from week 2 to week 8. Additionally, PRP treatment led to significant increases in sperm concentration, motility percentage, and the proportion of live and normal spermatozoa (P < 0.001), with maximum values observed at 28 and 60 days post-treatment, compared to day 0. Moreover, serum testosterone and nitric oxide (NO) levels were significantly higher (P < 0.001) in group II and remained elevated through the 8<sup>th</sup> week following injection, compared to baseline values and group I. In conclusion, this study demonstrates that autologous PRP treatment effectively increases sperm concentration, motility, and normal spermatozoa, improves testicular blood flow, and elevates testosterone and NO levels.

While traumatic injuries are the primary cause of lameness in animals, parasitic infections may be a potential factor in cases where the underlying cause of lameness remains unclear. Parasites may cause lameness in animals by inflicting extensive pathological damage to various organs and tissues, inducing severe anemia, producing endo- and exotoxins that act on the host, and more. However, the mechanisms by which many parasites induce lameness remain unknown. This review summarizes the literature on parasitic-induced lameness, which is classified as direct or indirect. Direct lameness occurs when parasites damage tissues such as muscles, bones, joints, tendons, and nerves, leading to a loss of function in these structures and subsequent lameness. Neurotoxins produced by some parasites may also cause coordination disorders, paralysis, and lameness in animals. Indirect lameness is caused by Égaré parasites-misplaced parasites that reside in tissues unrelated to their typical target location. These parasites may be found in the central nervous system, muscles, nerves, tendons, interdigital region, or femoral artery. Some endoparasites may cause tissue damage during migration, while others may induce lameness by affecting the circulatory system through blood parasites.</p>","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 3","pages":"181"},"PeriodicalIF":1.8,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12043529/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144037101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It also enables a painless surgery and stands a safer option for surgeries than general anesthesia. Due to the varying anatomy of the head among different species of exotic mammals, anesthesia techniques can differ significantly. Therefore, it is crucial to understand the topography of each species individually. This study describes the location of the cranial foramina associated with the trigeminal nerve, the topography of the surrounding bony structures (Table 1) and soft tissues in three red pandas (Ailurus fulgens fulgens) from the Wrocław Zoological Garden (Poland). It also presents techniques for anesthetizing nerves that pass through these foramina to alleviate postoperative pain after head surgeries as well as dental and orofacial procedures. The procedures described in this study were modified from known veterinary anesthesia techniques for cranial nerves in other animals. The results demonstrated variations in injection methods due to differences in the topography of the cranial foramina of the red panda.</p>","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 3","pages":"179"},"PeriodicalIF":1.8,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144021111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
