Resumo

Os hermafroditas verdadeiros são animais com intersexualidade, nos quais as gônadas masculinas e femininas se desenvolvem simultaneamente no mesmo indivíduo. Este trabalho relata um caso de hermafrodita na espécie suína após descarte de uma fêmea por diagnóstico de anestro. Tratava-se de uma fêmea com 222 dias de idade e 150 kg a qual havia sido selecionada para reprodução e permanecia em anestro. O indivíduo foi descartado e enviado para o abate em frigorífico sob inspeção federal. Após o abate foi observado no sistema genital aspectos anatômicos sugestivos de hermafroditismo. O sistema genital foi coletado, inspecionado macroscopicamente e conservado em formol a 10% para avaliação microscópica. Durante a análise macroscópica foi verificada a presença de vulva e vagina, contendo um pênis rudimentar. O útero, a cérvix, os cornos uterinos e oviduto estavam presentes e com ausência de anormalidade. Havia um ovário esquerdo com aspectos morfológicos de ciclicidade e folículos contendo oócitos de alta qualidade. À direita, entretanto, foi constatada a presença de um testículo, epidídimo e plexo pampiniforme. A avaliação histopatológica comprovou os achados macroscópicos, demonstrando um ovário contendo folículos, corpos lúteos e cistos foliculares; plexo pampiniforme; testículo e epidídimo com aspecto histológico normal, porém, com ausência de células espermatogênicas. Assim, com base nos achados macro e microscópicos descritos nesse relato de caso, o indivíduo foi considerado como hermafrodita verdadeiro.(AU)


True hermaphrodites are intersexual animals, in which both male and female gonads develop simultaneously in the same individual. This paper reports a case of a true hermaphrodite in the swine species after its culling for anestrus. The specimen was a female of 222 days of age and 150 kg of body weight, that was selected for reproduction and was permanently in anestrus. This individual was culled and sent to an abattoir under federal inspection. After slaughtering, it was observed in the reproductive tract anatomical aspects that suggested hermaphroditism. The reproductive tract was collected, evaluated macroscopically, and preserved in formaldehyde at 10 % to be evaluated by light microscopy. During the macroscopic analysis, the presence of a vulva and a vagina with a rudimentary penis was detected. The uterus, the cervix, uterine horns, and the oviduct were present and abnormalities were not detected. The left ovary exhibited morphological signs of cyclicity and contained follicles with high quality oocytes. On the right side, however, it was observed a testicle, epididymis, and a pampiniform plexus. The histopathological assessment corroborated the macroscopic findings, which demonstrated that the ovary had follicles, corpus luteum, and follicular cysts, and pampiniform plexus, testicle and epididymis were histologically normal, though with the absence of spermatogenic cells. Thus, based on the macro and microscopic findings described herein, the individual was considered a true hermaphrodite.(AU)

Resumo

The species of Pugilina cochlidium (Linnaeus, 1758) and P. erecta (Vermeij & Raben, 2009) has been studied in the present study. The female can be differentiated from the male by the absence of the cephalic penis and a complicated genital aparatus visible through the mantle skirt in both the sexes. In other aspects of the external features of female are quite to males. In both species the digestive system was similar with few differences in structure between each other. It consists of buccal mass, proboscis, salivary glands, accessory salivary glands, oesophagus, stomach, intestine, rectum and anus. The nervous system in both P. cochlidium and P. erecta is constituted by six ganglia which forms the circumoesophgeal ganglionic ring. Among the neogastropods there is a similarity in the organization of the reproductive systems. The female reproductive system is more complicated than that of male. The sexes are separated in these two species. The gross morphology of the reproductive system of P. cochlidium and P. erecta was almost similar. The present study aims to describe the digestive system, nervous system and reproductive system of two gastropods species P. cochlidium and P. erecta.


As espécies de Pugilina cochlidium (Linnaeus, 1758) e P. erecta (Vermeij & Raben, 2009) foram tomadas no presente estudo. A fêmea pode ser diferenciada do macho pela ausência do pênis cefálico e um complicado complexo genital visível através da saia do manto em ambos os sexos. Em outros aspectos das características externas da fêmea são bastante semelhantes aos dos machos. Em ambas as espécies, o sistema digestivo era semelhante, com poucas diferenças de estrutura entre si. Consiste em massa bucal, probóscide, glândulas salivares, glândulas salivares acessórias, esôfago, estômago, intestino, reto e ânus. O sistema nervoso em P. cochlidium e P. erecta é constituído por seis gânglios que formam um anel ganglionar circunoesofágico. Entre os neogastrópodes, há uma semelhança na organização dos sistemas reprodutivos. O sistema reprodutivo feminino é mais complicado que o masculino. Os sexos são separados nessas duas espécies. A morfologia macroscópica do sistema reprodutivo de P. cochlidium e P. erecta foi quase similar. O presente estudo tem como objetivo descrever o sistema digestivo, sistema nervoso e sistema reprodutivo de duas espécies, P. cochlidium e P. erecta.

A ocorrência de prolapso peniano em repteis é observada tanto em quelônios terrestres, quanto em squamatas, porém há a escassez de relatos em tartarugas marinhas documentados até o momento. Desta forma, objetivou-se relatar o processo de reabilitação de uma tartaruga-verde (Chelonia mydas) com prolapso peniano, de modo a nortear procedimentos clínicos e terapêuticos que possam propiciar maior sucesso na reabilitação destes animais. Uma tartaruga-verde (C. mydas), adulto, macho, foi resgatada no dia 02 de maio de 2020 na praia de Muriú, Ceará Mirim, Rio Grande do Norte, Brasil. O espécime encontrava-se ativo, responsivo, com bom escore corpóreo, hidratação moderada, presença de prolapso peniano com mucosa associada hiperêmica e parte necrosada, além disso, encontrava-se com a nadadeira anterior esquerda amputada. O animal recebeu suporte terapêutico à base de analgésicos, antibióticos, anti-inflamatórios, polivitamínicos e fluidoterapia. Foram realizados procedimentos cirúrgicos para remoção total do úmero e redução mecânica do prolapso peniano. Após 50 dias de reabilitação o animal teve alta médica e foi reintroduzido de volta ao mar. Conclui-se que o protocolo utilizado, tanto na reabilitação, quanto no tratamento conservativo do prolapso peniano mostrou-se eficaz na redução do edema, evitando assim a recidiva do prolapso.(AU)


The occurrence of penile prolapse in reptiles has been observed both in terrestrial turtles and squamates. However, there are few reports of penile prolapse in sea turtles published to date. This study aimed at reporting the rehabilitation process of a green sea turtle (Chelonia mydas) with penile prolapse, in order to guide clinical and therapeutic measures that can provide greater success in the rehabilitation of these animals. An adult male green sea turtle (C. mydas) was rescued on May 2, 2020 at Muriú beach, Ceará Mirim, Rio Grande do Norte, Brazil. The specimen was active and responsive, with a good body score and moderate hydration, and showed the presence of penile prolapse with associated hyperemic mucosa and necrosis. It also had the left anterior fin amputated. The animal received therapeutic support based on antibiotics, analgesics, anti-inflammatories, multivitamins, and fluid therapy. The surgical procedure for the complete removal of the humerus and mechanical reduction of penile prolapse was performed. After 50 days of rehabilitation, the animal was discharged and was reintroduced back to the sea. It is concluded that the protocol used was effective in reducing edema, thus preventing the recurrence of prolapse, both in rehabilitation and in the conservative treatment of penile prolapse(AU)

Background: Hermaphroditism is a rare congenital disease that causes ambiguous sexual features. True hermaphroditeshave testicular and ovarian tissue, whereas pseudohermaphrodites have only one type of gonadal tissue and genitalia, butsecondary characteristics of the opposite sex. Pseudohermaphrodites are classified as male or female according to theirgonads. Treatment of pseudohermaphroditism consists of surgical removal of the gonads including reconstruction of abnormal genitalia, especially if the urethra is involved. Therefore, the objective of this report is to describe a case of a malepseudohermaphrodite in a dog treated with clitoridectomy with urethrostomy.Case: A 7-month-old, mixed-breed dog was referred due to the presence of a flaccid structure similar to a small penis,containing an os clitoris, bulbourethral glands, and urethra protruding from the vulva. Physical examination, completeblood count and serum biochemistry were within normal ranges. Hormonal levels of estradiol, testosterone, and progesterone were 56.39 pg/mL, 127.9 ng/mL, and 0.892 ng/mL, respectively. The abdominal ultrasound and posteriorly theexploratory celiotomy found a normal size prostate and two round organs resembling testicles connected to a uterus-liketubular structure. The patient underwent surgical abdominal exploration that confirmed the ultrasonographic findings andled to gonadohysterectomy. Also, clitoridectomy and urethrostomy were performed to excise the protruded structure andmaintain normal urethral patency. The histopathological examination of the clitoris and penis confirmed it was a malegenital organ, however, the abdominal structures were compatible with the testicles, epididymis, uterus, and even a broadligament. These organs are normally found in cases of male pseudohermaphroditism. The...

The Ocelot (Leopardus pardalis) is the largest species of this genus, despite having broad distribution in the Americas; it is included in the main list of endangered species. Their conservation is widely studied, but there is a lack of studies about their morphology. In order to contribute to the knowledge of its reproductive system, five male and female ocelots were examined macro- and microscopically by histological techniques. Macroscopic analysis of the male reproductive system revealed presence of prostate and bulbourethral gland located caudally to the urinary bladder and a penis with small spicules. Microscopically, the testes were encased by the tunica albuginea and divided it into lobules with 5-10 tubules per lobe. In females, macroscopic analysis demonstrated two ovaries position dorsally in the sublumbar region and caudal to the kidneys. The bicornuate uterus is composed by uterine horns (12 to 14 cm in length), which travels from the ovaries in a caudal direction to form a small uterine body (4 cm in length). The ovary analysis revealed, in longitudinal section, medullary region composed of loose connective tissue, a stroma rich in blood vessels, and an external parenchymal region surrounded by a tunica albuginea. The results of the study confirmed the similarity between ocelot's reproductive system as domestic cat's ones and showing for the first time the complete morphological tool to highlight these organs and tissue in this male and female endangered wild felid specie. The present study open venue for other researchers to consider morphological and preservationist features and aimed to help at long-term conservation of wild felines.

The puparium of Dactylodeictes brevifacies was described based on fifty-eight specimens reared in laboratory until the emergence of adults. Larvae were collected under the bark of fallen trees in a Cerrado vegetation, Gallery forest; Palm swamp (Vereda) and open grassland (Campo Limpo) in States of Goiás and Tocantins, Brazil (New Record). The puparium was compared with that of Brachyodina lopesi, the most closely related species with a described puparium. Despite this species clearly shared the larval pachygastrinae features it has a remarkable character not know before for this subfamily: the presence of four pairs of ventral setae (V) in the eighth abdominal segment in ventral view, while in other larvae and puparia of this subfamily, there are five pairs of ventral setae. The adult male and female were described and figured.

In order to manipulate the mass rearing of natural enemies, temperature variations can be used. The effects are widely studied for their survival and developmental duration; however, there is little information about their reproductive system in the literature. Therefore, the purpose of this study was to evaluate the effects of different temperatures on the reproductive system of the predator Podisus nigrispinus (Dallas, 1851) (Hemiptera: Pentatomidae). The predator was kept at temperature conditions of 17, 21, 25, and 29 °C until reaching 15 days of age, the adult stage. The insects were then killed, measured for both weight and size, dissected, and then evaluated for the following parameters: length of the most developed ovariole; number of ovarioles per ovary; number of oocytes per the more developed ovarioles; number of oocytes per P. nigrispinus female; and the total area of the testicles was measured in the male insects. Results showed that as the temperature increased, the parameters were positively affected. These temperature variations can be used to manipulate the mass rearing of P. nigrispinus under controlled conditions.(AU)


As variações de temperatura podem ser utilizadas para manipular a criação massal de inimigos naturais e seus efeitos são amplamente estudados para a sobrevivência e duração de desenvolvimento, porém, existem poucas informações sobre o sistema reprodutivo na literatura. Por isso, o objetivo desse trabalho foi avaliar os efeitos de diferentes temperaturas sobre o aparelho reprodutivo do predador Podisus nigrispinus (Dallas, 1851) (Hemiptera: Pentatomidae). O predador foi mantido nas temperaturas de 17, 21, 25 e 29 °C até atingir 15 dias de idade na fase adulta. Esses insetos foram mortos, medido o peso e tamanho, dissecados e avaliados nos seguintes parâmetros: comprimento do ovaríolo mais desenvolvido; número de ovaríolo por ovário; números de ovócitos por ovaríolo mais desenvolvidos; número de ovócitos por fêmea; e, nos machos, área total do testículo. Os resultados evidenciaram que a medida que aumenta a temperatura os parâmetros foram afetados positivamente. Essas variações de temperatura podem ser utilizadas para manipular a criação massal de P. nigrispinus em condições controladas.(AU)

Although a recent revision of the genus Glyphidops Enderlein covered most its known, some of the Brazilian forms were not surveyed. Here we take advantage of the excellent morphological work available in the literature and redescribe Glyphidops (Glyphidops) filosus, based on 91 specimens (43 males and 48 females) from the States of Amazonas and Goiás, including Brasília, Brazil. We also provide a study of male genitalia using scanning electron microscopy (SEM) and female genitalia and spermathecae, using light microscopy (LM). We present descriptions of the following structures in male genitalia: epandrium, hypandrium, surstyli, cerci and sections of aedeagus, and in female genitalia: oviscape, bursa copulatrix, ‘S’ bend and spermatheca. An update list of Brazilian species of Glyphidops Enderlein is also presented.

This study describes a case of a dog with a lacerated penile tear treated with partial penectomy followed by successful semen collections for artificial insemination. A 1.5-year-old Jack Russel Terrier with normal libido, genital organs and semen, had a penile laceration after copulation. The dog underwent a partial penectomy without orchiectomy, thus preserving the possibility of semen collection. Semen was successfully collected at 45 and 53 days after surgery, and it was used for artificial insemination of two bitches, one of which became pregnant. Therefore, this report demonstrated that semen may be collected from dogs with partial penectomy for artificial insemination, this technique has the potential to preserve fertility of dogs with penile lesions that require penectomy.(AU)


Este estudo descreve o caso de um cão que teve laceração peniana tratada por penectomia parcial seguida de coleta de sêmen para inseminação artificial bem sucedida. Um cão Jack Russel Terrier de 1,5 anos, com libido, órgãos genitais e sêmen normais, teve laceração peniana após cópula. O cão foi parcialmente penectomizado sem orquiectomia, preservando a possibilidade de coleta de sêmen. A coleta de sêmen foi bem sucedida 45 e 53 dias após a cirurgia, sendo utilizado para inseminação artificial de duas cadelas, uma delas se tornando gestante. Portanto, sêmen para inseminação artificial pode ser coletado em cães parcialmente penectomizados, esta técnica revelando ser uma potencial forma de preservação da fertilidade de cães com lesões penianas que necessitem penectomia.(AU)

Resumo

As doenças do sistema reprodutor são comuns na medicina veterinária, e algumas delas requerem tratamento cirúrgico associado ao tratamento clínico. A cirurgia reprodutiva abrange uma variedade de técnicas que visam alterar a capacidade do animal de se reproduzir, auxiliar no parto ou tratar ou prevenir doenças dos órgãos reprodutivo. Objetivou-se descrever nessa revisão particularidades cirúrgicas de distúrbios do sistema reprodutor masculino para tratamento da fimose, parafimose, hipospadia, neoplasia e abscesso prostático, e indicações da orquiectomia; e particularidades cirúrgicas do sistema reprodutor feminino para tratamento da hiperplasia endometrial cística/piometra, neoplasias ovarianas, uterinas, vaginais e mamárias, hiperplasia e prolapso vaginal, e indicações para ovário-histerectomia. Além disso, relatar cinco casos clínicos de patologias do sistema reprodutivo que a resolução foi cirúrgica.(AU)


Diseases of the reproductive system are common in veterinary medicine, and some require surgical treatment associated with clinical treatment. Reproductive surgery encompasses a variety of techniques aimed at altering the animal's ability to reproduce, assist in whelping, or treat or prevent diseases of the reproductive organs. We aimed to describe in this review surgical particularities of disorders of the male reproductive system for treatment of phimosis, paraphimosis, hypospadias, neoplasia and prostatic abscess, and orchiectomy indications; and surgical particularities of the female reproductive system for the treatment of endometrial cystic hyperplasia/pyometra, ovarian, uterine, vaginal and mammary neoplasms, hyperplasia and vaginal prolapse, and indications for ovariohysterectomy. In addition, we report five clinical cases of reproductive pathologies that resolution was surgical.(AU)

A cirurgia reprodutiva abrange uma variedade de técnicas que visam alterar a capacidade do animal de se reproduzir, auxiliar no parto ou tratar ou prevenir doenças dos órgãos reprodutivo. Objetivou-se descrever nessa revisão particularidades cirúrgicas de distúrbios do sistema reprodutor masculino para tratamento da fimose, parafimose, hipospadia, neoplasia e abscesso prostático, e indicações da orquiectomia; e particularidades cirúrgicas do sistema reprodutor feminino para tratamento da hiperplasia endometrial cística/piometra, neoplasias ovarianas, uterinas, vaginais e mamárias, hiperplasia e prolapso vaginal, e indicações para ovário-histerectomia. Além disso, relatar cinco casos clínicos de patologias do sistema reprodutivo que a resolução foi cirúrgica.


Diseases of the reproductive system are common in veterinary medicine, and some require surgical treatment associated with clinical treatment. Reproductive surgery encompasses a variety of techniques aimed at altering the animal's ability to reproduce, assist in whelping, or treat or prevent diseases of the reproductive organs. We aimed to describe in this review surgical particularities of disorders of the male reproductive system for treatment of phimosis, paraphimosis, hypospadias, neoplasia and prostatic abscess, and orchiectomy indications; and surgical particularities of the female reproductive system for the treatment of endometrial cystic hyperplasia/pyometra, ovarian, uterine, vaginal and mammary neoplasms, hyperplasia and vaginal prolapse, and indications for ovariohysterectomy. In addition, we report five clinical cases of reproductive pathologies that resolution was surgical.

Resumo

Caraguata Bechyné, 1954 (Galerucini, Galerucina) includes 38 species exclusively Neotropical, among them two sympatric species, C. atricornis (Clark, 1865) and C. guaporensis Bechyné, 1958. Given the lack of morphological studies in this group, we aimed to characterize the adult morphology of two species, providing descriptions, illustrations and comparisons of structures of the head, thorax, abdomen and genitalia. The external morphology includes the description of head, thorax, abdomen and its appendices; the internal morphology comprises endosternites, and male and female genitalia. Some similarities were observed, such as pubescence, mouth parts, apparent sexual dimorphism on ventrite V, spermatheca and vaginal palpi. The main differences are in (1) the body and antenna shape, (2) the antenna color pattern, (3) the depression of the pronotum, (4) the presence/absence of the tibial spur, (5) the form of the median lobe, (6) the tegmen and (7) the sternite VIII of the females. The morphological study of these species contributes to the knowledge of Galerucina, presenting important specific characteristics not employed until now. Thus, it can be a contribution for studies of comparative morphology, systematics and evolution of the group.(AU)

Resumo

This study investigated the effects of tributyltin (TBT) on the morphology of the genital system of the gastropod Stramonita rustica in southern Bahia, Brazil. For this, 330 specimens were collected during the summer of 2014 at eight sampling points to ascertain whether male sex organs had developed in addition to the complete female genital tract in females (= imposex). The analyses were made under a stereoscopic microscope. Imposex and their associated indexes, and the sterile females, exhibited the highest rates in harbors and shipyards areas. Despite the total ban of TBT in anti-fouling paints on a global scale since 2003, the results of this and other studies indicate the continued use of those paints on the Brazilian coast. This shows the inefficiency of existing legislation and the need to strengthen enforcement of the ban.(AU)


Este estudo investigou os efeitos de tributil-estanho (TBT) sobre a morfologia do sistema genital do gastrópode Stramonita rustica (Lamarck, 1822) no Litoral Sul da Bahia, Brasil. Para isso, 330 espécimens foram coletados durante o verão de 2014 em oito pontos de amostragem, para verificar se os órgãos sexuais masculinos tinham se desenvolvido para além do trato genital feminino completo (= imposex). As análises foram feitas sob um microscópio estereoscópico. O imposex e seus índices associados, assim como as fêmeas estéreis, apresentaram as maiores taxas em áreas portuárias e estaleiros. Apesar da proibição total do TBT em tintas anti-incrustantes em escala global desde 2003, os resultados deste e de outros estudos indicam a continuidade de uso dessas tintas na costa brasileira. Isso mostra a ineficácia da legislação vigente e reforça a necessidade de se cumprir integralmente o banimento.(AU)

Resumo

In order to solve the affinities of the species of Isotes Weise, 1922, a detailed morphological comparative study was carried out based on type-species of Isotes and its junior synonym,Synbrotica Bechyné, 1956. Isotes tetraspilota (Baly, 1865) and Isotes borrei (Baly, 1889) had their morphology of mouthparts, endosternites, wings and both male and female genitalia compared by the first time. A new synonymy is established between Isotes borrei (Baly, 1889) and Isotes crucigera (Weise, 1916) syn. nov. based on external and genitalia morphology. New structures for Section Diabroticites Chapuis, 1875 are presented and discussed.(AU)


Para resolver as afinidades das espécies de Isotes Weise,1922, um estudo morfológico comparado foi realizado com base nas espécies-tipo deIsotes e de seu sinônimo-júnior,Synbrotica Bechyné, 1956. Isotes tetraspilota (Baly, 1865) e Isotes borrei (Baly, 1889) tiveram a morfologia de suas peças bucais, endosternitos, asas e genitálias masculina e feminina comparadas pela primeira vez. Uma nova sinonímia é estabelecida entre Isotes borrei (Baly, 1889) eIsotes crucigera (Weise, 1916) syn. nov., com base na morfologia externa e genitália. Estruturas inéditas para a Seção Diabroticites Chapuis, 1875 são apresentadas e discutidas.(AU)
