Contenção farmacológica do gato-do-mato-pequeno, Leopardus tigrinus, para colheita de sêmen, pela associação de tiletamina zolazepam e xilazina

This paper reports the anesthetic effects of the combination of tiletamine HCl, zolazepam HCl, and xylazine HCl in tigrinas, Leopardus tigrinus Schreber, 1775 (Fam. Felidae), submitted to semen collection by electroejaculation. Three different protocols and the individual anesthetic doses were calculated by interspecific allometric scaling, based on the usual recommendations for a 10.0 kg domestic dog: On Protocol 1 (n=10) the basis for calculation was 5.0mg/kg for tiletamine + zolazepam and 0.5mg/kg for xylazine; on Protocol 2 (n=12) 5.0mg/kg for tiletamine + zolazepam and 0.75mg/kg for xylazine; and on Protocol 3 (n=11) 5.0mg/kg for tiletamine + zolazepam and 1.0mg/kg for xylazine. The tigrinas were anesthetized on three different occasions with a minimum interval of 30 days. During 120 minutes after the drug administration cardiac and respiratory frequencies, rectal temperature, limb myorelaxation and sensitivity to deep pain were monitored. Latency period, anesthetic period, and contamination of the semen with urine were also monitored. From a total of 32 collections, 10 samples (31.2%) and 18 aliquots (0.07%) were contaminated and rejected, but this episodes were not detrimental for semen analysis and processing. A discrete increase in rectal temperature during electroejaculation caused by muscle contraction, followed by temperature decrease, was observed. Cardiac and respiratory frequency varied during the experiment, but remained within physiological standards for the species. The three tested protocols showed to be safe and effective to produce analgesia and anesthesia in L. tigrinus during semen collection by electroejaculation.

Uso do fixador esquelético externo Tipo II para osteossíntese de tibiotarso em galinhas da raça Plymouth Rock Branca: modelo experimental para uso em aves selvagens

The efficiency of the Type II external skeletal fixator for the treatment of tibiotarsus fracture in eight adult White Plymouth Rock chickens was evaluated. The individuals were pre-medicated with morphine sulfate and anesthetized with halothane, and submitted to a diaphysary osteotomy in the left tibiotarsus, performed with an oscillatory saw. Four Kirschner wires were inserted through the bone cortices, being two proximally and two distally to the fracture. After the fracture reduction the ends of both proximal and distal wires were twisted in distal or proximal direction, respectively, being the wires connected by two bars of autopolymerizing acrylic resin, in the external lateral and medial faces of the limb. The return to full capability to use the member was observed in 20.00±7.09 days, and the bone healing occurred in 35.12±8.72 days. The results of this study showed that open reduction and use of Type II external skeletal fixator is an effective method for the treatment of tibiotarsus fractures in White Plymouth Rock chickens.

MULTICENTRIC LYMPHOMA IN A GIANT ANTEATER (MYRMECOPHAGA TRIDACTYLA)

Abstract:  Neoplastic disease is not well documented in giant anteaters. This report describes a disseminated lymphoma in an adult male giant anteater (Myrmecophaga tridactyla) from the City Zoo of Curitiba, State of Paraná, Brazil. No clinical signs were noticed before its death, except for a slight inappetence. At postmortem examination, pale white to yellow, variably sized nodules infiltrated the heart, liver, and intestinal lymph nodes. Histologically, two distinct cell populations were present in the nodular lesions: one characterized by smaller cells, primarily lymphocytic in nature, and another characterized by larger rounded cells with loose chromatin and frequently indented nuclei resembling histiocytes. Giant binucleated cells were occasionally observed. Mitotic figures numbered 2–3 mitotic figures/×400 field. Both cellular populations presented with moderate pleomorphism, large nuclei, a high nucleus-to-cytoplasm ratio, distinct nucleoli, and coarse nuclear chromatin. The neoplasia was classified as a form of multicentric lymphohistiocytic lymphoma (Rappaport Classification) and as an intermediate grade lymphoma (National Cancer Institute Working Formulation).

Iatrogenic nasolacrimal duct obstruction following tooth extraction in a cat.

A 10-year-old DSH cat was referred for a dental evaluation and extraction procedure. Subsequently, the animal developed an acute onset of ocular discharge. Ophthalmologic examination revealed presence of unilateral ocular mucoid discharge leading to a diagnosis of epiphora secondary to nasolacrimal duct obstruction. Dacryocystorhinography was performed and confirmed the presence of a nasolacrimal duct obstruction, presumably acquired after an invasive dental procedure. Additionally, a vinyl cast in situ study of the nasolacrymal apparatus was performed to demonstrate the route of the nasolacrimal duct in the cat and its relationship to oral dental structures. This report documents an unusual case in which excessive inflammation/edema following tooth extraction caused acute epiphora secondary to extraluminal compression of the distal nasolacrimal duct.

Gyrostigma rhinocerontis (Diptera: Oestridae, Gasterophilinae) em rinocerontes-brancos (Ceratotherium simum) importados da África do Sul: ocorrência em Itatiba, São Paulo

As larvas dos dipteros da subfamilia Gasterophilinae da familia Oestridae parasitam ungulados perissodactilos, tanto domesticos (equideos) quanto selvagens (rinocerontes e equideos). O parasito gastrico dos rinocerontes africanos e Gyrostigma rhinocerontis (anteriormente Gyrostigma pavesii), que na fase larval pode ser encontrada nas fezes dos hospedeiros, e chega a medir 40mm de comprimento. O adulto e a maior mosca daquele continente, atingindo ate 41mm de comprimento, e envergadura de 71 mm. O genero Gyrostigma nao ocorre naturalmente no Brasil, onde anteriormente existia somente um relato do achado de larvas, nas fezes de um rinoceronte-branco oriundo da Africa do Sul nos anos 90 do seculo XX, e albergado num zoologico localizado no Rio Grande do Sul. Este artigo apresenta dados sobre o achado, em um zoologico no municipio de Itatiba, Estado de Sao Paulo, Brasil, de larvas de Gyrostigma rhinocerontis nas fezes de um grupo de rinocerontes-brancos (Ceratotherium simum) importados legalmente da Africa do Sul, onde eram mantidos em uma fazenda de preservacao com criacao manejada, em 2005. Sao relatadas tambem as medidas tomadas para controle do caso e prevencao da disseminacao do parasito, e se discutem os riscos da globalizacao, que viabiliza o trânsito internacional e intercontinental de animais selvagens, com riscos potenciais de adaptacao de parasitos exoticos a novos ecossistemas.
