Natural disasters and the rise of zoonotic diseases: A case of post-earthquake disseminated cryptococcosis in a dog.

Cryptococcosis is a systemic zoonotic disease that is challenging to diagnose based on clinical findings in cats and dogs due to the nonspecific nature of its clinical presentation. This case report aims to document the first confirmed case of disseminated cryptococcosis caused by Cryptococcus neoformans in a dog in Turkey and to highlight the potential link between natural disasters such as earthquakes and the emergence of zoonotic diseases in domestic animals. A two-and-a-half-year-old spayed female Cocker Spaniel presented with increased respiratory sounds, skin lesions, facial swelling and enlarged lymph nodes.

Unlocking immunotherapy targets: programmed death 1 and its ligand and their correlation with tumour grade in feline injection site sarcoma.

In this study, the immunohistochemical expression of programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1), which could facilitate a novel approach to immunotherapy for feline injection site sarcomas (FISSs), was investigated. Treatment strategies based on the suppression of this pathway are possible for tumours expressing PD-1/PD-L1. In this context, FISSs were histologically classified, the grade of sarcoma and the intensity of lymphocyte infiltration determined and PD-1 and PD-L1 expression evaluated in tumours of different grade.

Comparative evaluation of platelet-rich plasma, autologous blood serum, and umbilical cord serum for corneal healing after penetrating keratoplasty in New Zealand rabbits.

This study aimed to evaluate the effects of platelet-rich plasma (PRP), autologous blood serum (ABS), and umbilical cord serum (UCS) on corneal healing following penetrating keratoplasty (PK). A total of 120 New Zealand white rabbits, forty were designated as donors, while the remaining eighty rabbits were randomly divided into four groups after undergoing PRP Group (n = 20), ABS Group (n = 20), UCS Group (n = 20) and Control Group (n = 20). Corneal opacity score, corneal vascularization, corneal staining, histopathological analysis, and immunohistochemical analysis (including CD4, CD8, and major histocompatibility complex [MHC] II) were assessed at postoperative 1, 2, 3, and 12 weeks.

Effects of fish oil on methotrexate-induced reproductive damage in rats.

Methotrexate (MTX) is a folic acid antagonist that is commonly used in paediatric and adult oncology to treat a variety of malignancies. Internal organs, including the testis, are severely cytotoxic and genotoxic to MTX. Omega-3, as an antioxidant, has been shown to protect rat testis tissue from injury.

Protective role of the dried white mulberry extract on the reproductive damage and fertility in rats treated with carmustine.

The present study investigated the protective effect of dried white Mulberry extract (DWME) against carmustine (Crm) induced biochemical alterations and spermatological, histopathological, and fertility damage in Wistar albino rats. Male rats were divided into four groups (control, Crm, Crm + DWME, and DWME group). It was found that Crm decreased the motility.

Investigation of brain mast cells in ovine encephalitic listeriosis.

Mast cells in the brain are associated with increased inflammation during the acute period following exposure to infection; these cells are important for destroying the infectious agents. We investigated the relation between histopathological lesions and mast cells in sheep brains infected with . Pons and medulla regions from 17 infected and eight normal sheep brains were examined.

ISOLATION OF STREPTOCOCCI FROM A FATAL CASE OF MYOCARDITIS IN A CAPTIVE BROWN BEAR (URSUS ARCTOS).

A 10-yr-old, male brown bear ( Ursus arctos ) from Bursa Zoo in Turkey died without any apparent signs. Severe purulent pericarditis and myocarditis with mild ascites, lung edema, and moderate liver congestion were observed during necropsy. Microscopically, there were severe neutrophilic infiltrations in the myocardium and thoracic lymph nodes.

Meningoencephalitis caused by pathogenic Sarcocystis species in a naturally infected sheep in Turkey.

A 3-year-old sheep was examined after an acute onset of hind limb paralysis and ataxia. At necropsy, central nervous system, pulmonary and intestinal hyperaemia and ecchymoses in the aortic arch were observed. Main microscopic lesions were confined to the heart, cerebrum and cerebellum.

Parasitologic and pathologic observations of the house sparrow (Passer domesticus).

This study describes the parasites and related pathologic observations in the house sparrow (Passer domesticus). In total, 48 birds were examined and 41 sparrows were found to be infected with one or more endoparasites (85.4%).
