Lasalocid Poisoning in Buffalo Calves in the State of Pará, Brazil

Background: Ionophore antibiotics are food additives with coccidiostatic or antimicrobial action; they are also used as growth promoters, ruminal pH regulators, volatile fatty acid molar modifiers, and methanogenesis reducers. However, these compounds have the potential to cause microbial resistance, in addition to the risk of intoxication. Ionophore poisoning may be caused by excessive intake, sensitivity of certain animal species, and concomitant use with other drugs. In Brazil, cases of ionophore poisoning in buffalos are rare. This study aims to describe the epidemiological, clinical, and pathological findings of lasalocid poisoning in buffalo calves.Case: A visit was made to a farm in the municipality of Mojú, Pará state to care for Murrah buffalo calves. After weaning, the buffalos were grazed in paddocks with Panicum spp., and received a supplement of mineral, protein, and vitamin. This supplement contained, per kg, 250 g PB, 50 g Ca, 20 g P, 8 g S, 39 g Na, 20 mg Co, 557 mg Cu, 200 mg Fe, 12.4 mg Se, 2040 mg Zn, 0.19 mg biotin, 26750 IU of vitamin A, 4175 IU of vitamin D, 155 IU of vitamin E and 300 mg/kg of lasalocid. The product was made available to all calves, at 1-2 g/kg body weight (BW), according to the manufacturer's recommendations. Older calves were raised together with those less than 30 days old; as a result, the older calves tended to eat more, which could lead to a supplementation consumption of more than 1 kg body weight per animal per day. It was reported that between 40 and 60 days after the introduction of this supplement, 16 calves fell ill and died due to apathy, motor instability, tremors, and distended neck. The herd had a mortality rate of 33.3%. Two calves underwent a necroscopic examination at the Pathology Section of the Veterinary Institute of the Federal University of Pará. Macroscopic examination revealed extensive pale areas in the skeletal muscles, myocardium, and tongue. Fragments of these muscles and various organs were collected, fixed in 10% buffered formalin, processed according to the routine histological technique, and stained with hematoxylin-eosin and Masson's trichrome stain. Microscopic examination of the histologic samples revealed foci of muscle atrophy and necrosis characterized by an increase in cytoplasmic eosinophilia associated with the loss of stretch marks, and hyperchromatic nuclei that were displaced to the periphery. The necrosis of the muscle fibers was highlighted by Masson's trichrome staining.Discussion: The diagnosis of lasalocid poisoning in buffalo calves was based on epidemiological data, clinical findings, results of macroscopic and histopathological examination, and based on the estimated ionophore intake, obtained directly from the supplement label and by the calf's handler. Based on the absence of stratification of the calves by similarity of age and because the buffalo calves older than 30 days could eat more than 1 kg of the supplement (containing 300 mg/kg of lasalocid), it was possible to estimate the intake of lasalocid per kg CP (body weight). Therefore, the intake of lasalocid by a 70-kg buffalo calf in approximately 90 days and daily supplement consumption between 1 and 1.5 kg would be between 4.2 and 6.4 mg/kg of body weight. This report reinforces that notion that buffalo calves should never ingest ionophores; however, if necessary, strict protocols must be followed to avoid poisoning in these animals. This study highlighted the fact that stratification of buffaloes by different age groups during feeding became a risk factor that allowed greater consumption by older animals; this led to the estimated consumption of 4.2-6.4 mg/kg of lasalocid.Keywords: ionophores, ruminants, buffalo calves, muscle necrosis.Descritores: ionóforos, ruminantes, bezerros búfalos, necrose muscular.Título: Intoxicação por lasalocida em bezerros búfalos no Estado do Pará, Brasil

Angiographic Embolization followed by Excision of Large Cellular Angiofibroma of the Vulva

Introduction: Cellular angiofibroma is a rare benign mesenchymal tumor, occurring almost exclusively in the superficial soft tissues of the genital region. Some of these lesions presents as large, hypervascularized masses. There are no reports in the literature to date on the challenges of resection of hypervascularized vulvar masses, or of hypervascularized cellular angiofibroma.Materials and methods: We describe a case of a cellular angiofibroma of the vulva and the surgical approach with tumoral vessel embolization and posterior resection.Case: A 47-year-old women was referred to vulvar pathology section of Italian Hospital of Buenos Aires for evaluation of left vulvar mass. A pelvic angiography was performed 5 days prior to surgery. It showed a hypervascularized formation at the level of the left vulva at the expense mainly of branches of the left internal pudendal artery. A complete resection was performed afterwards at our institution. The histopathological diagnosis was compatible with cellular angiofibroma.Conclusion: We consider that surgical planning is essential and has to be performed with a multidisciplinary approach. Angiographic embolization should be taken into account as a valid resource when planning a surgery with a high risk of blood loss in order to decrease morbidity.

Penyakit Layu Fusarium Pada Tanaman Pisang di Provinsi NAD: Sebaran dan Identifikasi Isolat Berdasarkan Analisis Vegetative Compatibility Group

ABSTRAK. Penyakit layu yang disebabkan oleh cendawan Fusarium oxysporum f. sp. cubense (Foc) merupakan penyakit paling berbahaya pada tanaman pisang. Untuk mendapatkan teknik pengendalian yang tepat, maka informasi tentang distribusi dan karakter biologi patogen tersebut perlu diketahui. Penelitian ini bertujuan mengetahui distribusi penyakit layu Fusarium di Provinsi Nanggroe Aceh Darussalam (NAD) dan varietas pisang yang diserangnya serta mengidentifikasi isolat Foc berdasarkan analisis vegetative compatibility group (VCG). Survei dan pengumpulan sampel tanaman pisang terserang penyakit dilakukan pada bulan Januari 2007 dan Juli 2008. Isolasi dan pemurnian isolat dilakukan di Laboratorium Hama dan Penyakit Tanaman, Balai Penelitian Tanaman Buah (Balitbu) Tropika Solok pada bulan Februari 2007 dan Agustus 2008. Analisis VCG dilakukan di Departement of Primary Industry, Plant Pathology Section, Indooroopilli Australia dan Laboratorium Hama dan Penyakit Tanaman Balai Penelitian Tanaman Buah Tropika sejak bulan Juli 2007 sampai bulan Juli 2009. Tester VCG berjumlah 17 nomor yang berasal dari Department of Primary Industry, Plant Pathology Section, Indooroopilli Australia. Hasil penelitian menunjukkan bahwa penyakit layu Fusarium ditemukan di semua lokasi pengamatan di Provinsi NAD pada empat varietas pisang, yaitu Barangan (AAA), Raja (AAB), Kepok (ABB/BBB), dan Siem (ABB). Dari 50 isolat Foc yang dikoleksi terkelompok ke dalam dua VCG, 37 isolat (74%) termasuk dalam VCG 01213/16 (Tropical Race 4), ditemukan pada tiga varietas (Barangan, Kepok, dan Raja), sembilan isolat masuk VCG 01218 (Ras 1) ditemukan hanya pada varietas Siem, sedangkan VCG empat isolat yang menyerang pisang varietas Siem belum ditemukan. Foc VCGs 01213/16 (TR4) paling dominan ditemukan di Provinsi NAD, baik dari jumlah, sebaran lokasi, maupun ragam varietas yang diserangnya. Data ini menginformasikan bahwa pengembangan tanaman pisang di Provinsi NAD harus dilakukan secara selektif serta mempertimbangkan langkah-langkah preventif dan pengendalian yang tepat.<br /><br />ABSTRACT. Jumjunidang, Edison, Riska, and Hermanto, C 2012. Fusarium Wilt Disease on Banana in NAD Province: Distribution and Identification of Isolates through Vegetative Compatibility Group Analysis. Wilt disease caused by Fusarium oxysporum f. sp. cubense (Foc) is the most dangerous pathogen on banana. Knowledge of the distribution and biological characters of the pathogen is very important to arrange an effective control technique. The objectives of this study were to reveal distribution of Fusarium wilt disease in Nanggroe Aceh Darussalam (NAD) Province and infected banana varieties as well as to identify of Foc isolates with vegetative compatibility group (VCG) analysis Survey and collection of samples of infected banana plants in NAD Province were carried out in January 2007 and July 2008. Isolation and purification of the isolates with single spore techniques were done at Plant Protection Laboratory of Indonesian Tropical Fruit Research Institute (ITFRI), Solok in February 2007 and August 2008. Vegetative compatibility group analysis was performed at Department of Primary Industry, Plant Pathology Section, Indooroopilli Australia and Plant Protection Laboratory of ITFRI from July 2007 to July 2009. Seventeen VCG testers were originated from Department of Primary Industry, Plant Pathology Section, Indooroopilli Australia. The results showed that Fusarium wilt disease was found in all surveyed locations in NAD Province on four banana varieties, i.e. Barangan (AAA), Raja (AAB), Kepok (ABB/BBB), and Siem (ABB). Fifty isolates of the pathogen Foc have been collected and grouped into two VCGs, 37 isolates (74%) were grouped into VCG 01213/16 (Tropical Race 4) attacking three varieties (Barangan, Kepok, and Raja), nine isolates were clustered into VCG 01218 (Race 1) attacking Siem variety only, and the other four isolates from Siem variety had not been identified yet. Foc VCG 01213/16 (TR4) was very dominant in NAD Province, in terms of numbers, location, and distribution of attacked varieties. These findings inform that the development of banana plants in the NAD province should be done selectively and consider both preventive measures and appropriate controls.<br />
