Anisakidae are nematodes that commonly parasitize in the coelomic cavity and viscera of several fish species. They can be found in flesh, which is why they have an important economic and public health impact. The aim of the current work was to assess the presence and prevalence of Anisakis larvae in fish species caught in the coastal area of the Karaburun Peninsula in Vlora Bay (Albania). A total of 856 of wild teleosts and 219 specimens of farmed fish were collected over a 5-year period (from 2016 to 2020). The results showed that out of a total of 1075 analyzed samples, 361 (33.58%) were parasitized with L3 larvae. In particular, only Solea vulgaris returned negative results, while Sparus aurata, Dicentrarchus labrax, and Sardinella aurita showed the lowest prevalence (4.55%, 9.17%, and 10.53%, respectively) and mean abundance (0.84, 1.19, and 0.92, respectively). Conversely, Scomber japonicus and Scomber scombrus showed the highest prevalence (74.07% and 68.00%, respectively) and mean abundance (188.24 and 249.82, respectively). The data suggest that the coastal area of the Karaburun Peninsula (southern Albania) may be a high-risk area for zoonotic diseases, and the consumption of raw or undercooked fish caught in the Vlora district could result in the acquisition of human anisakiasis. For these reasons, it is necessary to improve the surveillance plan.

This study evaluated heavy metal levels (Pb, Cd, Hg, As, Cu) and the presence of Salmonella spp. and Listeria monocytogenes in mussels and commonly consumed fishery products from the Marmara region of Türkiye. Health risks were evaluated using total hazard quotient (THQ) and hazard index (HI) values, while microbial risks in fresh and ready-to-eat (RTE) products were estimated via the Risk Ranger tool. Among 625 samples, Hg (36.96%; CI95 = 33.27–48.81), Pb (9.76%; CI95 = 7.67–12.34), and Cd (19.36%; CI95 = 16.45–22.64) exceeded permissible limits, except in crabs, which remained compliant. Anchovy, sardines, bluefish, shrimps, and octopus met EU Cd limits. Shrimps exhibited higher As_in levels than crabs (p < 0.05), while squids had significantly higher As_in than octopus but lower Pb (p < 0.05). Microbiological analysis detected Salmonella spp. in 4.00% of samples (CI95 = 2.50–6.30) and L. monocytogenes in 4.24% (CI95 = 2.70–6.59). Surmullet, bluefish, red mullet, crabs, mussels, and octopus tested negative for both, while anchovy was negative for Salmonella spp. only. THQ and HI assessments emphasized the need for environmental monitoring to mitigate heavy metal contamination. The detection of pathogens highlights the importance of stringent surveillance measures to ensure the safety of fishery products and bivalves.

Birds exhibit naturally high blood glucose concentrations, a physiological trait that, unlike in mammals, does not lead to typical pathological consequences such as diabetes mellitus. This review explores the unique features of glucose metabolism in birds, with a particular focus on the anatomy and function of the avian pancreas, the roles of key hormones such as insulin and glucagon, as well as the distinctive mechanisms of glucose absorption and utilization. Evidence suggests a dominant role of glucagon over insulin, along with adaptations such as insulin resistance and antioxidant defenses, which may contribute to birds’ apparent resilience to hyperglycemia-related complications. Despite these adaptations, cases of diabetes mellitus have been reported, primarily as secondary to other pathologies, including pancreatitis, hemochromatosis, infections, and toxicities. Diagnosis remains challenging due to interspecies variability and the lack of standardized assays. Treatment, mainly via insulin therapy, has shown mixed outcomes, often limited by the underlying disease severity. This review highlights the need for species-specific diagnostic tools and a deeper investigation into the pathophysiology of glucose regulation in birds, aiming to improve clinical outcomes, develop standardized therapies, and ultimately broaden the perspectives of comparative endocrinology.

Goji berry (GB) shows beneficial effects on human health, although its effects on the male rabbit have been little investigated. This study examines the impact of GB dietary supplementation on the semen traits, antioxidant capacity of seminal plasma, and histological features of the reproductive tract of rabbit buck. Eighteen rabbits were distributed into two dietary groups: one receiving a commercial feed (Control), and the other a feed supplemented with 1% of GB (Goji). After a nutritional adaptation period of 60 days, the animals were subjected to semen collection every 15 days. The semen traits, libido, antioxidant, and inflammatory parameters were collected and analyzed. The rabbits were sacrificed after 60 days, and tissues of the genital tract were analyzed. Compared to the Control group, the Goji group showed higher spermatozoa concentration, motility, and vitality (p < 0.05), as well as fewer abnormal spermatozoa and a higher libido (p < 0.1). Histological features such as functional activity and hyperplasia were improved by GB and correlated with some semen traits (p < 0.05). Conversely, antioxidant and anti-inflammatory parameters were unaffected by the diet. These findings suggest that GB acts on the tissues of the reproductive tract positively influencing semen quality, although further studies are needed to understand the effect on oxidative stress.

Trace elements, which may have harmful health effects, are present in the environment at varying concentrations. In Albania, data on exposure risks are limited. This study aimed to assess and compare the concentrations of various trace elements (aluminum, arsenic, boron, calcium, cadmium, chromium, copper, iron, potassium, magnesium, manganese, nickel, lead, and zinc) in the hair of cattle and sheep raised in Central Albania (Tirana and Elbasan Counties). Hair samples were collected from 25 cattle and 25 sheep per county and analyzed using inductively coupled plasma–optical emission spectroscopy. Zinc concentrations were significantly higher in cattle than in sheep (p = 0.029), while no differences were observed between counties (p > 0.05), indicating similar environmental conditions. Copper (17.84, 95%CI: 13.63–16.34 and 15.84, 95%CI: 14.00–17.69 mg/kg in cattle, and 15.58, 95%CI: 13.61–17.56 and 14.14, 95%CI: 12.07–16.20 mg/kg in sheep, in Elbasan and Tirana County, respectively), arsenic (2.08, 95%CI: 1.45–1.21 and 1.51, 95%CI: 1.19–1.81 mg/kg in cattle, 1.73, 95%CI: 1.38–2.07 and 1.39, 95%CI: 1.02–1.75 mg/kg in sheep, in Elbasan and Tirana County, respectively), and cadmium (2.36, 95%CI: 1.63–2.07 and 2.00, 95%CI: 1.68–2.32 mg/kg in cattle, 2.00, 95%CI: 1.59–2.40 and 1.71, 95%CI: 1.39–2.02 mg/kg in sheep, in Elbasan and Tirana County, respectively) concentrations exceeded the values reported in the literature, likely due to contamination from local mining and metal processing activities. Further research is needed to determine the sources of contamination and assess potential risks to animal and human health.

Goji berries (Lycium barbarum), rich in antioxidant and immunomodulatory compounds, have shown potential benefits for male reproductive health. This study aimed to evaluate the impact of dietary Goji berry (GB) supplementation on immune-related and antioxidant gene expression in the male reproductive tract of rabbits. Eighteen 7-month-old New Zealand White rabbit bucks were randomly assigned to two groups: a control group (n = 9) receiving a standard diet, and a Goji group (n = 9) receiving the same diet supplemented with 1% GB. After 60 days of nutritional adaptation and then 60 days of treatment, tissues from the testes, epididymis, seminal vesicles, prostate, and bulbourethral glands were collected and analyzed using quantitative real-time PCR. Gene expression analysis focused on immune markers (TLR4, IL-1β, IL-10, and TNFα) and antioxidant enzymes (SOD1, CAT, and GPX). Significant modulation was observed only in the epididymis, where TLR4 and GPX were significantly downregulated in the Goji group (p = 0.0274 and p = 0.007, respectively), while IL-1β and TNFα showed a downward trend. No significant differences were found in the other tissues. These results suggest that Goji berry supplementation exerts tissue-specific effects, particularly in the epididymis, by modulating inflammation and oxidative stress. This supports its potential use as a natural nutraceutical strategy to enhance male fertility in rabbits.
