Squamous cell carcinoma in a tuatara (Sphenodon punctatus)     

WD Roe  MR Alley  SM Cooper  L Hazley 《New Zealand veterinary journal》2013,61(5):207-210

CASE HISTORY: A mature male tuatara was presented with a history of recurrent cloacal prolapse.

CLINICAL AND PATHOLOGICAL FINDINGS: The prolapsed tissue included a 12 mm diameter mass, which histologically showed cords and nodules of neoplastic epithelial cells.

DIAGNOSIS: The mass was diagnosed as a squamous cell carcinoma with ulceration of the overlying stratified squamous epithelium and diffuse inflammation of the surrounding dermis.

CLINICAL RELEVANCE: This case presented a rare opportunity to investigate squamous cell carcinoma in a long-lived lower vertebrate species. Future recurrence or metastasis of the mass may add useful information to the current base of knowledge of the behaviour of malignant neoplasms in reptiles.  相似文献   

Bacterial sinusitis as a cause of beak deformity in an Antipodes Island parakeet (Cyanoramphus unicolor)     

BD Gartrell  MR Alley  T Kelly 《New Zealand veterinary journal》2013,61(4):196-198

CASE HISTORY: From 26 days of age, an Antipodes Island parakeet (Cyanoramphus unicolor) was noted to have a severe beak deformity and reduced bodyweight gain compared to its nest mate. The bird was euthanised at 43 days of age.

CLINICAL AND PATHOLOGICAL FINDINGS: The beak abnormality consisted of distortion of the right nares and severe shortening resulting in deviation of the upper maxilla to the right and cranially. On sectioning the head, copious mucoid material was found in the infraorbital sinus and the bony sinus architecture was disrupted. Histopathological examination of the infraorbital sinuses revealed a large focus of chronic but active inflammation, bony lysis on the right side and pockets of a mixed population of bacteria.

DIAGNOSIS: Severe beak deformity, likely secondary to bacterial sinusitis.

CLINICAL RELEVANCE: The case illustrates the need to look for underlying aetiologies to beak malformation, particularly in young parrots.  相似文献

Disseminated mycosis in a Jackson's Chameleon (Chamaeloeo jacksonii)     

BD Gartrell  MR Alley  K Geschke 《New Zealand veterinary journal》2013,61(1)

Extract

An adult male Jackson's chameleon died with a history of intermittent periorbital swelling, anorexia and abnormal posture. On post mortem examination, there were multiple granulomas in the tongue, liver and soft palate. Histopathology revealed chronic granulomatous inflammation with yeast-like organisms and non-septate branching hyphae. Fungal cultures resulted in the growth of a Penicillium spp that could not be speciated further. The peri-orbital tissues contained a mix of necrotic bone and muscle. Sections of the brain showed three large adjacent focal areas of infarction. The kidneys showed acute nephritis and sclerotic glomeruli. The cytoplasm of some renal tubular epithelial cells contained highly eosinophilic granules. This ‘sexual segment granulation’ is normal in sexually active males of some lizard species.  相似文献   

Heat stress as a manageable risk factor to mitigate pneumonia in lambs

Abstract

Extract

The paper by Goodwin et al (2004 Goodwin, KA, Jackson, R, Brown, C, Davies, PR, Morris, RS and Perkins, NR. 2004. Pneumonic lesions in lambs in New Zealand: patterns of prevalence and effects on production. New Zealand Veterinary Journal, 52: 175–9. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) which appeared in the August 2004 issue of the New Zealand Veterinary Journal highlighted the prevalence and costs to the sheep industry of pneumonia in lambs. The costs are considerable, and the article begs the question, “what can sheep farmers do to reduce the effects of pneumonia in lambs?”  相似文献

Effect of processing conditions on trace elements in fish roe from six commercial new zealand fish species     

Bekhit Ael-D  Morton JD  Dawson CO 《Journal of agricultural and food chemistry》2008,56(12):4846-4853

The concentrations of trace elements in fish roes and the effect of processing conditions (karasumi-like or karashi mentaiko) were investigated in six commercial fish species from New Zealand. The studied elements were As, Cd, Cr, Cu, Hg, Pb, and Zn, and the roes were from the following species: chinook salmon ( Oncorhynchus tshawytscha), hoki ( Macruronus novaezelandiae), southern blue whiting ( Micromesistius australis), hake ( Merluccius australis), blue warehou ( Seriolella brama), and barracouta ( Thyrsites atun). The concentrations of As, Cd, Cr, Hg, and Pb in the roes were lower than literature values for fish muscles. Only Zn in barracouta roe and Cu in salmon roe and their products were relatively higher than the generally accepted levels in fish muscles and could be of safety concern. Hence, the consumption of barracouta and salmon roes among certain parts of the population needs to be monitored and assessed. Dry salting (karasumi-like) processing increased ( P < 0.001) the concentrations of the studied trace elements while salting fermentation (karashi mentaiko) processing tended to decrease the levels of trace elements. Fermentation may be a useful process to decrease the level of toxic trace elements.  相似文献
