“…In the South of Brazil the coatis' breeding season occurred between October and February (Indrusiak et al, 2003). According to Beisiegel (2001) the breeding season occurred between August-September and births between October-November in the South-east of Brazil.…”

Semen samples (n=105) were collected through eletroejaculation from six adult male coatis (Nasua nasua) between January 2007 and December 2008 at Universidade Federal de Mato Grosso Zoo, Cuiabá, Brazil. Mean values were: volume (mL); concentration (sperm/mL); total motility (%); progressive sperm motility (scale, 0-5); live spermatozoa (%); acrossome integrity (%); primary defects (%); and secondary defects (%). There was high correlation between total motility and live sperm; total motility and progressive sperm motility; total motility and acrossome integrity; live sperm and progressive motility; live sperm and acrossome integrity and volume and concentration. The method for semen collection was considered safe and efficient. It can be used for the evaluation of breeding potential of coati in captivity and for the establishment of new assisted reproductive technology (ART) for threatened neotropical carnivores species.Keywords: Procyonidae, semen, eletroejaculation, reproduction RESUMO Amostras de sêmen (n=105) foram coletadas por eletroejaculação em seis coatis (Nasua nasua) machos adultos entre Janeiro de 2007 a Dezembro de 2008 no Zoológico da Universidade Federal de

“…Os membros e as pontas das orelhas são negras e apresentam pelagem curta, o que os diferenciam do cachorro-do-campo (Moro--Rios et al 2008). São onívoros e oportunistas (Facure & Giaretta 1996, Beisiegel 2001, Santos-Júnior & Macedo 2007, e sua dieta consiste de frutas, ovos, artrópodes, répteis, pequenos mamíferos e carcaças de animais mortos (Facure & Monteiro-Filho 1996, Santos-Júnior & Macedo 2007. No Brasil, esta espécie pode ser encontrada em ambientes abertos naturais ou alterados, presentes em biomas como a Amazônia, Mata Atlântica, Caatinga, Pantanal e Cerrado (Berta 1982, Facure & Giareta 1996, Juarez & Marinho-Filho 2002, Jácomo et al 2004.…”

RESUMO.-O cachorro-do-mato (Cerdocyon thous) pertence à família Canidae, encontra-se amplamente distribuído pela América do Sul. Devido à escassez literária a respeito da morfologia desta espécie objetivamos colaborar com o conhecimento da anatomia do arco aórtico e seus ramos colaterais. Foram estudados quatro animais, sendo 2 machos e 2 fêmeas oriundos da Mina de Bauxita, Paragominas, Pará, Brasil/Terra Ltda, sob autorização da SEMA-PA nº 455/2009, que morreram por causas naturais. O sistema arterial foi preenchido com látex corado em vermelho e fixado em solução aquosa de formoldeído 10%. O arco aórtico de Cerdocyon thous apresentou em sua origem apenas dois vasos, o tronco braquiocefálico e a artéria subclávia esquerda. Do tronco braquiocefálico originou-se o tronco bicarotídeo, que se bifurcou nas artérias carótidas comum direita e esquerda, e artéria subclávia direita. Das artérias subclávias ocorreu a formação do tronco costocervical, artéria vertebral, artéria torácica interna, artéria cervical superficial e ao atingir o espaço axilar passa a ser chamada de artéria axilar em ambos os antímeros. Concluímos que o arco aórtico de Cerdocyon thous é similar ao de outros animais domésticos com relação ao número de ramificações em sua origem. INTRODUÇÃOO cachorro-do-mato ou guaraxaim (Cerdocyon thous) é um mamífero da família dos canídeos, amplamente distribuído pela América do Sul (Facure & Giaretta 1996). Tais animais, noctívagos, medem cerca de 65cm de comprimento, com Crab-eating fox (Cerdocyon thous) belongs to the Canidae family distributed in South America. Due to literary scarcity regarding the morphology of this species, we objectifiked to collaborate with description of the anatomy of the aortic arch and its collateral branches. We studied four foxes, 2 males and 2 females, from Mina Bauxita, Paragominas, Pará, Brazil/Terra Ltda, under authorization of SEMA-PA nº 455/2009, that died of natural causes. The arterial system was filled with red latex and fixation with 10% formaldehyde solution. The aortic arch of Cerdocyon thous showed that in its origin are two vessels, brachiocephalic trunk and left subclavian artery. From brachiocephalic trunk originates the bicarotid trunk, bifurcated into left and right carotid common arteries, and right subclavian artery. The subclavian arteries originates the costocervical trunk, vertebral artery, internal thoracic artery, superficial cervical artery, to reach the axillary space, and passes to be called axillary artery on both sides. We conclude that the aortic arch of Cerdocyon thous is similar to the one in other domestic animals regarding the number of ramificastions at its origin.

“…Coatis (Nasua nasua) have high adaptability (Beisiegel 2001, Franciolli et al 2007, Campos 2009) and are distributed in almost all-Brazilian territory (Teixeira & Ambrosio 2006). Despite this, little is known regarding the reproductive biology and sex abnormalities in this species.…”

This paper reports a case of unilateral extracorporeal ectopic testes in a captive coati (Nasua nasua) in the State Park of Dois Irmãos Zoo, Recife/PE, Brazil. The testicle was located in the subcutaneous tissue of the inguinal region not adhered to the surrounding tissues. After bilateral orchiectomy, both testes were measured, fixed with 10% formalin buffered and embedded in paraffin for histopathological evaluation. The left testis measured 1.2 cm width by 1.7cm length, and the right one measured 1.5 cm width by 2.0 cm length. The ectopic testes had seminiferous epithelium without post-meiotic germ cell lines. The non-ectopic testis had several changes in the seminiferous epithelium that indicated degeneration. In both epididymis, the lumen did not contain sperm and the major epithelial structural alterations were more distinct in the epididymis associated to the ectopic testicle. In conclusion, the ectopic testis and epididymis had lesions compatible with testicular exposition to body temperature. Non-ectopic epididymis and testis had minor lesions but could be related to the infertility of the coati.
