Abstract: farms raising ostriches are becoming popular in brazil lately, but as an exotic species, there is little information regarding diseases that affect these animals in our environment. a five-month-old ostrich had cough, anorexia, weight loss, mild dispneia, normal body temperature, and died within 8 days from the beginning of the clinical signs. grossly, there were multiple nodules in the lung and air sacs. histopathologically, a multifocal necrotizing and granulomatous pneumonia with intralesional radiating septated and branching hyphae with morphological features of aspergillus sp. was observed. in the air sacs, in addition to the hyphae and adjacent inflammatory reaction, there were multiple mycelia with conidiophores on the inner surface. aspergillus fumigatus was isolated from the affected tissues. based on the histopathological and mycological findings, a severe mycotic pneumonia and air sacculitis caused by aspergillus fumigatus was diagnosed. to the best of our knowledge, this is the first reported case of aspergillosis in an ostrich in brazil.

Abstract: Criatórios de avestruz têm se tornado comuns no Brasil, mas por se tratar de espécie exótica, as informa es sobre as doen as desses animais no nosso ambiente s o escassas. Um avestruz de cinco meses de idade apresentou tosse, anorexia, perda de peso, dispnéia discreta, temperatura corporal normal e morreu oito dias após o início dos sinais clínicos. Macroscopicamente foram observados nódulos múltiplos no pulm o e nos sacos aéreos. Histolopatogicamente, observou-se pneumonia granulomatosa e necrosante multifocal com hifas ramificadas e septadas intralesionais com características morfológicas de Aspergillus sp. Nos sacos aéreos, além das hifas e processo inflamatório adjacente haviam vários micélios com conidióforos na superfície interna. Foi isolado Aspergillus fumigatus dos tecidos afetados. De acordo com os achados histopatológicos e micológicos firmou-se o diagnóstico de pneumonia e aerossaculite micótica severa causada por Aspergillus fumigatus. Com base nas informa es disponíveis na literatura, esse é o primeiro caso de aspergilose em avestruz documentado no Brasil.

Abstract: the relationship between thyroid, gonads and bone morphology was investigated in 5 month-old wistar rats, castrated and kept in hyperthyroid or euthyroid state for periods of 30, 60 and 90 days. a non-castrated control group was maintained in the same condition. at the end of each period, plasma concentrations of free t4, progesterone and estradiol were measured. the bones from each group were submitted to radiological and histological analysis. hyperthyroidism in intact rats caused variation in bone morphology throughout the experiment, leading to loss of trabecular bone tissue at day 60, due to increased bone resorption. at day 90 there was no bone loss, because the increase in bone resorption was accompanied by higher bone apposition. in castrated euthyroid rats reduction in progesterone levels inhibited the bone apposition, causing a slight loss of trabecular bone tissue in vertebrae and alveolar bone at day 30, which was intensified at days 60 and 90, affecting cortical bone tissue. the administration of thyroxine to castrated rats reversed osteopenia at days 30 and 60, which did not occur at day 90 when bone loss was more extensive. in conclusion, hypoprogesteronism and hypoestrogenism alter bone metabolism and the bone response to hyperthyroidism depends on the plasma profile of sex steroids, time of exposure and bone tissue configuration.

Abstract: A foliculogênese e a esteroidogênese ovarianas foram estudadas em ratas adultas hipertireóideas. O hipertireoidismo foi induzido em 27 ratas Wistar com cinco meses de idade pela administra o diária de 50μg de L-tiroxina. Outras 27 ratas foram mantidas em estado eutireóideo e serviram como controle. Aos 30, 60 e 90 dias após o início do tratamento, nove ratas de cada grupo foram sacrificadas, os ovários inspecionados, pesados e processados para avalia o histomorfométrica e o plasma sangüíneo colhido para dosagem de T4-livre, estradiol e progesterona. As concentra es plasmáticas de T4-livre foram significativamente maiores nas ratas hipertireóideas aos 30, 60 e 90 dias, e o peso médio dos ovários foi significativamente maior somente aos 90 dias. Já o número de folículos secundários e terciários e de corpos lúteos foi significativamente maior aos 60 ou aos 90 dias, mas a taxa percentual de atresia folicular só foi diferente aos 90 dias. O número de folículos primários e pré-ovulatórios, assim como as concentra es plasmáticas de estradiol e progesterona, n o diferiram entre grupos e entre períodos. Concluiu-se que o hipertireoidismo estimula a foliculogênese ovariana em ratas sexualmente maduras e diminui a atresia folicular.

Abstract: A crossbreed Zebu cow had both ovaries enlarged with multiple cysts. Most cysts were lined by well differentiated keratinizing stratified squamous epithelium and filled with keratinized lamellar material. Some cysts were lined by an epithelial layer that ranged from single cuboidal, double cuboidal epithelium, stratified non keratinized epithelium, and areas of keratinizing stratified squamous epithelium. Single or double layered cuboidal epithelia of the cysts expressed low molecular weight cytokeratin 7, whose expression was absent in the keratinizing stratified squamous epithelia of same cysts. Conversely, high molecular weight cytokeratins 1, 5, 10, and 14 were strongly expressed by the keratinizing stratified epithelium.Squamous metaplasia of the rete ovarii was diagnosed. Squamous metaplasia of the rete ovarii, may account for some of the previously described squamous lesions in the ovary, which may have been misinterpreted as teratoma or epidermoid cysts.Stratified keratinizing squamous epithelium in the ovary has been historically associated with the diagnosis of ovarian teratoma in cows [1,2]. McEntee (1990) [1] has even used the terminology “ovarian dermoid cyst” as a synonym of benign ovarian teratoma, mentioning that this lesion is more common in Zebu cattle [1,3]. More recently, the diagnosis of epidermoid cyst has been proposed for the first time in the veterinary literature to describe ovarian cysts lined by stratified keratinizing squamous epithelium in the absence of hair follicles and adnexal glands [4].In women, epidermoid cysts have been described, although there are evidences that most epidermoid cysts are in fact insufficiently sampled teratomas, leading some investigators to question the appropriateness of the diagnosis of epidermoid cysts [5]. Ovarian squamous lesions in women are often associated with teratomas, although it may be found as a metaplastic component in ovarian carcinomas or ovarian endometriosis [5,6].

Abstract: ovarian folliculogenesis and steroidogenesis were studied in hyperthyroid adult rats. hyperthyroidism was induced in 27 five month-old wistar rats by daily administration of 50μg l-thyroxin. other 27 rats were maintained in euthyroid state as controls. at 30, 60 and 90 days after the beginning of the treatment, nine rats from each group were sacrificed. the ovaries were weighed, inspected and processed for histomorphometric evaluation. plasmatic levels of free t4, estradiol and progesterone were determined. the levels of t4 were significantly higher in the hyperthyroid rats at 30, 60 and 90 days, but significant differences on the ovarian weight were detected only at 90 days. the number of secondary and tertiary follicles and of corpus luteum was greater at 60 or 90 days, but the rate of follicular atresia was different only at 90 days. no significant differences were observed on the number of primary and pre-ovulatory follicles and on the concentrations of estradiol and progesterone. our data suggest that hyperthyroidism stimulates ovarian folliculogenesis in sexually mature rats. furthermore, there is a reduction on the rate of follicular atresia.
