Endangered flora in protected areas of Rio de Janeiro municipality ­ Rio de Janeiro State, Brazil

This study presents a qualitative analysis of endangered species occurrences in conservation units of Rio de Janeiro, one of the largest Brazilian municipalities in population size. Increasing human activities trigger changes in biodiversity, promote fragmentation, and reduce species distribution ranges, which can ultimately lead to declines in population sizes. One of the main goals of protected areas (PAs), such as conservation units, is to protect and conserve biodiversity. Here, we compiled all vascular plant species recorded within Rio de Janeiro PAs by consulting the Reference Center for Environmental Information (SpeciesLink), Flora do Brasil (2020), and primary data records contained in management plans. We compared this compilation with the list of Brazilian endangered plant species, verifying whether the management plans presented specific programs for these species. Of the 60 surveyed PAs, 24 had records of endangered species and only 17 had management plans, 14 of which had a specific program that contemplated the monitoring and/or conservation of endangered species. A total of 70 endangered species were recorded. The highest numbers of endangered species were found in the Tijuca National Park (41) and the Pedra Branca State Park (17), the two largest PAs with the two largest forest fragments. Despite the high number of endangered species and the number of protected areas that harbor them, few internal programs address endangered species conservation and management. Thus, efforts to maintain endangered species in protected areas can be aided by field data collections that confirm their occurrence and maintenance in these PAs.(AU)

Lafora's disease in a free-ranging toco toucan (Ramphastos toco) with neurologic disease

Lafora's disease is a genetic disease associated to mutations in genes that encodes laforin and malin, which results in intracellular polyglucan storage. The present report describes a case of Lafora's disease in a toco toucan with episodes of incoordination and myoclonus that resulted in traumatic lesions and fracture of the left hindlimb. The bird was euthanized and submitted to necropsy. Microscopically there were abundant PAS-positive and diastasis-resistant Lafora's inclusion bodies in neurons in the cerebellum, supporting the diagnosis of Lafora's disease.(AU)

Urethral obstruction secondary to Staphylococcus felis chronic urethritis and hepatoid gland adenoma in a captive ocelot (Leopardus pardalis)

A male adult ocelot (Leopardus pardalis) kept under human care developed anuria, which progressed to death. Grossly, the urinary bladder was markedly dilated and filled with red discolored urine containing blood clots. In addition, the animal had a hepatoid cell adenoma adjacent to the urethra, which likely caused partial urethral occlusion. Microscopically, there was a predominantly neutrophilic, fibrinous and hemorrhagic urethritis, cystitis, and pyelonephritis with intralesional gram-positive cocci. Microbiologic culture followed by MALDI-TOF MS analysis resulted in the identification of isolates from the urine and urethra as Staphylococcus felis.(AU)

Extraction of antioxidant and antimicrobial phytochemicals from corn stigma: a promising alternative to valorization of agricultural residues / Extração de fitoquímicos antioxidantes e antimicrobianos do estigma do milho: uma alternativa promissora para valorização de resíduos agrícolas

The discovery of new natural additives from agro-industrial waste is considered an important research topic. This study investigated the feasibility of ultrasound-assisted extraction (UAE) of antioxidant compounds from corn stigma (CS) and the effect of independent variables (time and solid-solvent ratio) and their interaction in the extraction of CS. Results indicated that the UAE method increases the antioxidant activity and reduces the extraction time by 67%. Optimized conditions for the simultaneous extraction of antioxidants and polyphenols from CS were obtained using 5 min and a solid-solvent ratio of 0.05 g mL-¹. The CS extract obtained by UAE was characterized by ESI-ToF-MS and 27 phytochemicals were reported. The extract showed promising antifungal and antibacterial activities against 23 of the studied microorganisms. Therefore, the CS extract obtained by the UAE can be used as a source of bioactive and antimicrobial compounds for use as a functional ingredient in the food and pharmaceutical industry.

A descoberta de novos aditivos naturais a partir de resíduos agroindustriais é considerada um importante tópico de pesquisa. Este estudo teve como objetivo investigar a viabilidade da extração assistida por ultrassom (EAU) de compostos antioxidantes do estigma do milho (EM) e o efeito de variáveis independentes (tempo e relação sólido-solvente) e sua interação na extração de EM. Os resultados indicaram que a EUA aumenta a atividade antioxidante e reduz o tempo de extração em 67%. Condições otimizadas para a extração simultânea de antioxidantes e polifenóis do EM foram obtidas com 5 min e uma relação sólido-solvente de 0,05 g mL-¹. O extrato de EM obtido pela EUA foi caracterizado por ESI-ToF-MS e 27 fitoquímicos foram encontrados. O extrato apresentou atividades antifúngicas e antibacterianas promissoras contra 23 dos micro-organismos estudados. Portanto, o extrato de EM obtido pela extração assistida por ultrassom pode ser utilizado como fonte de compostos bioativos e antimicrobianos para uso como ingrediente funcional na indústria alimentícia e farmacêutica.

Different calcium sources on the productive performance and bone quality of meat quail / Diferentes fontes de cálcio sob o desempenho produtivo e qualidade óssea de codornas de corte

This study was developed to examine the effect of using charru mussel-, maçunim- and oyster-shell meals as calcium sources on the productive performance, carcass yield and bone parameters of meat quail. A total of 250 one-day-old non-sexed European quail were used. The birds were distributed into five treatments (calcium sources: calcitic lime, calcium carbonate, charru mussel shell meal, maçunim shell meal or oyster shell meal) in a completely randomized design with five replicates and ten birds per experimental unit. Feed intake, weight gain and feed conversion were evaluated from one to 35 days. At 35 days, two birds with the average weight of the plot were slaughtered per plot and used for analysis of carcass yield and bone parameters. There were no significant differences (P > 0.05) in feed intake, weight gain, feed conversion, carcass yield or tibia dry matter content, ash content and strength. The charru mussel-, maçunim- and oyster-shell meals can be used as calcium sources in the diet of European quail without affecting their productive performance, carcass yield or bone mineralization.

Objetivou-se avaliar o efeito da utilização das farinhas de conchas de sururu, maçunim e ostra como fontes de cálcio sobre o desempenho produtivo, rendimento de carcaça e parâmetros ósseos de codornas de corte. Foram utilizadas 250 codornas europeias, não sexadas, com um dia de idade. As aves foram distribuídas em delineamento inteiramente casualizado, constituído por cinco fontes de cálcio (calcário calcítico, carbonato de cálcio, farinha de conchas de sururu, farinha de conchas de maçunim e farinha de conchas de ostras), com cinco repetições e dez aves por unidade experimental. Foram avaliados o consumo de ração, ganho de peso e conversão alimentar no período de um a 35 dias. Aos 35 dias, duas aves de peso médio de cada parcela foram abatidas e utilizadas para as análises de rendimento de carcaça e parâmetros ósseos. Não foram observadas diferenças significativas (P > 0,05) para os dados de consumo de ração, ganho de peso, conversão alimentar, rendimento de carcaça, matéria seca, cinzas e resistência óssea de tíbias. As farinhas de conchas de sururu, maçunim e ostra podem ser utilizadas na alimentação de codornas europeias, como fontes de cálcio, sem afetar o desempenho produtivo, rendimento de carcaça e a mineralização óssea das aves.

Avian mycobacteriosis in a naturally infected captive nocturnal curassow (Nothocrax urumutum)

A senile female nocturnal curassow (Nothocrax urumutum) kept under human care was found dead. Grossly, the lungs were congested and had a nodule with 2.0 cm in diameter adhered to the left lung. Histologically, there were multifocal to coalescent areas of necrosis characterized by deposition of amorphous and eosinophilic material with large amount of cellular debris, surrounded by numerous epithelioid macrophages, multinucleated Langhans giant cells, occasional lymphocytes and plasma cells. Ziehl-Neelsen stained sections demonstrated myriad of intralesional alcohol-acid resistant bacilli (BAAR). DNA extracted from lung samples were evaluated by nested polymerase chain reaction resulting in mycobacterial DNA identification. This is the first reported case of mycobacteriosis in a nocturnal curassow.(AU)

Staphylococcus aureus-induced pyogranulomatous dermatitis, osteomyelitis, and meningitis with Splendore-Hoeppli reaction in a cat coinfected with the feline leukemia virus and Leishmania sp

This report describes a case of a pyogranulomatous dermatitis, osteomyelitis, and meningitis with Splendore-Hoeppli reaction caused by Staphylococcus aureus in a sheltered female adult cat coinfected with the feline leukemia virus (FeLV) and Leishmania sp. The cat had a mild anemia and marked increased total leukocytes, particularly band and segmented neutrophils. The cat had laboratorial diagnosis of FeLV and Leishmania sp. infections. Clinically, the cat had extensive and multifocal areas of ulceration in cranial region. Due to the progression of cutaneous lesions, progressive weight loss, and the risk for other sheltered animals, the cat was euthanized. Microscopically, there was marked pyogranulomatous ulcerative dermatitis, osteomyelitis and meningitis, with multiple large intralesional colonies of Gram-positive cocci associated with Splendore-Hoeppli reaction. Aerobic bacterial isolates were identified as S. aureus by MALDI-ToF MS. Leishmania sp. DNA sequences were detected in liver and spleen, and amastigotes were demonstrated in skin sections by immunohistochemistry. In conclusion, here we describe a case of S. aureus-induced pyogranulomatous meningitis with SH reaction in a cat naturally coinfected with FeLV and Leishmania sp(AU)

Seminoma in a gray brocket deer (Mazama gouazoubira) with unilateral cryptorchidism

Cryptorchidism is the incomplete descent of the testes and associated structures, and cryptorchid testes are more likely to develop testicular neoplasms, such as seminoma. This is the first report of a seminoma in a cryptorchid wild-caught gray brocket deer (Mazama gouazoubira). The animal developed a unilateral seminoma with classical histopathological findings and benign behavior. Six months after the orchiectomy the cervid presented a metatarsal opened fracture, dying during the orthopedic surgery. No macro or micrometric metastasis was observed at the necropsy.(AU)

Ectoparasitic flies (Diptera: Streblidae) on bats (Mammalia: Chiroptera) from a Private Natural Heritage Reserve in southeastern Brazil

Due to the small number of records of Streblidae on bats, despite extensive study on these mammals in the state of Rio de Janeiro, a survey was carried out in an area of the Atlantic Forest. The present study was carried out at Bom Retiro Farm Natural Heritage Private Reserve. We captured 401 bats of 17 species, 13 genera, and four families; bat flies infested 221 bats of only four species. Carollia perspicillata (Linnaeus, 1758) has the highest fly diversity, with seven fly species: Trichobius joblingi (Wenzel, 1966) (n = 23), Megistopoda proxima (Séguy, 1926) (n = 15), Strebla guajiro (García & Casal, 1965) (n = 15), Aspidoptera falcata (Wenzel, 1976) (n = 6) Paratrichobius longicrus (Miranda Ribeiro, 1907) (n = 8), Paraeuctenodes similis(Wenzel 1976) (n = 3), and Trichobius anducei (Guerrero, 1998) (n = 1). Two species infested Platyrrhinus lineatus (É. Geoffroy, 1810): Aspidoptera falcata (n = 1) and Anastrebla caudiferae (Wenzel, 1996) (n = 1). Paradyschiria parvula (Falcoz, 1931) (n = 11) infested Noctilio leporinus (Linnaeus, 1758) and M. proxima (n = 12) and Trichobius uniformis (Curran, 1935) (n = 1) infested Sturnira lilium (É. Geoffroy, 1842). Sturnira lilium has the highest infestation rate, with ten out of 46 captured individuals parasitized, followed by Carollia perspicillata, with 33 out of 164 captured parasitized, and by P. lineatus with only two parasitized individuals out of ten. Among 97 streblid flies captured, M. proxima was the most abundant (27.83%), followed by T. joblingi (23.71%), and S. guajiro (15.46%). All remaining bat fly species represented 33%. Paradichyria parvula has the first record for Rio de Janeiro State.

Wafer-type biscuit waste in meat-quail diets / Resíduo de biscoito tipo wafer na alimentação de codornas de corte

Two experiments were carried out to evaluate the nutritional composition and effect of different levels of inclusion of wafer-type biscuit waste (WW) in the diet of European quail on production performance, carcass yield and economic viability. In the metabolizability trial, WW showed 87.45% DM, 4,128.53 kcal/kg GE, 3,833.14 kcal/kg AME, 3,818.92 kcal/kg AMEn, 9.37% CP and 17% EE. The metabolizability coefficients of DM, GE, EE and CP were 93.20, 92.85, 93.01 and 47.16%, respectively. In the performance trial, feed intake decreased linearly (P 0.05) by WW inclusion. The WW inclusion levels did not influence (P>0.05) carcass yield. The diet with 20% inclusion of WW provided the best financial return. Wafer-type biscuit waste can be included up to the level of 20% in quail diets without compromising production performance, carcass yield or the economic viability of the activity.

Foram realizados dois experimentos com o objetivo de avaliar a composição nutricional e a utilização de diferentes níveis de inclusão de resíduo de biscoito tipo wafer (RB), na alimentação de codornas europeias, sobre o desempenho produtivo, rendimento de carcaça e viabilidade econômica. No ensaio de metabolizabilidade, o RB apresentou 87,45% de MS, EB de 4.128,53 kcal/kg, EMA de 3.833,14 kcal/kg, EMAn de 3.818,92 kcal/kg, com 9,37% de PB e 17% de EE. Os valores do coeficiente de metabolizabilidade (CM) para MS, EB, EE e PB foram: 93,20; 92,85; 93,01 e 47,16%, respectivamente. No ensaio de desempenho, houve redução linear (P 0,05) pela inclusão do RB. Não houve efeito (P>0,05) dos níveis de inclusão do RB sobre o rendimento de carcaça. A ração com 20% demonstra ser mais rentável. Recomenda-se a inclusão do RB até o nível de 20% nas dietas para codornas, sem comprometer o desempenho produtivo, o rendimento de carcaça e a viabilidade econômica.
