“…Leukocytosis with neutrophilia can be caused by the interaction between the crotalic venom and the animal organism, inducing a typical acute-phase response with release of catecholamines, cellular mediators and humor, besides serum chemotactic factors. Leukocytosis with neutrophilia has also been reported in the initial phase of crotalic envenomation in humans (20,26,32,34) and animals (14,27,29,36,38).…”

ABSTRACT:The present study aimed at evaluating clinical and laboratory aspects during experimental envenomation by Crotalus durissus terrificus in dogs treated with antiophidic serum. Twenty-one dogs were divided into three groups of seven animals each. Group I received 1mg/kg venom (sc); Group II received 1mg/kg venom (sc), 50mg antiophidic serum (iv), and fluid therapy including 0.9% NaCl solution (iv); and Group III received 1mg/kg venom (sc), 50mg antiophidic serum (iv), and fluid therapy including 0.9% NaCl solution containing sodium bicarbonate diluted to the dose of 4mEq/kg. The clinical signs of ataxia, sedation, flaccid paralysis, mydriasis, eyeball paralysis, mandible ptosis, sialorrhea, vomiting and diarrhea observed in the dogs were very similar to those observed in humans. The decrease in hemoglobin, hematocrit, erythrocyte, platelet and fibrinogen levels, prolongation of clotting time, prothrombin time (PT) and activated partial thromboplastin time (APTT), as well as hypocellularity in the bone marrow characterized anemia, thrombocytopenia and blood incoagulability, as well as hypofibrinogenemia and decreased bone-marrow activity. Important bleeding was not observed. Increased numbers of leukocytes and neutrophils and decreased numbers of lymphocytes and eosinophils characterized an acute inflammatory response and stress caused by generalized pain. The employed antiophidic serum was effective and all animals survived.

RESUMO.-[Comparação da microbiota de cascavéis (Crotalus durissus terrificus) de vida-livre e cativeiro.] Este estudo avaliou e comparou a microflora aeróbica da cavidade oral, cloaca e veneno de serpentes Crotalus durissus terrificus recém-capturadas da natureza e mantidas sob quarentena (WQ), mantidas em cativeiro coletivo (CC) e em cativeiro individual (IC). A eficácia de drogas antimicrobianas de agentes isolados foi também avaliada. Foram isolados microorganismos dos grupos I, II e III respectivamente: 29 (63.04%), 38 (90.48%) e 21 (42.86%) da cloaca; 15 (32.61%), 3 (7.14%) e 25 (51.02%) da cavidade oral, e finalmente 2 (4.35%), 1 (2.38%) e 3 (6.12%) do veneno. As bactérias mais frequentes foram Pseudomonas aeruginosa, Proteus vulgaris e Morganella morganii, com sensibilidade para amikacina, gentamicina, norfloxacina, sulfazotrina e tobramicina. Serpentes mantidas no cativeiro semi-aberto mostraram menor nú-mero de agentes infecciosos em cavidade oral, talvez devido ao ambiente de cativeiro com diferentes gradientes de temperatura, água corrente, ausência de manejo diário, ampla circulação de ar, possibilidade de movimentação pelos animais, limpeza diária e acesso ao Sol.

Resumo: O presente trabalho trata de uma revisão bibliográfica exploratória e correlacional de casos publicados sobre acidentes ofídicos com infecções secundárias e análise microbiológica dos abscessos, bem como da microbiota oral das serpentes. As buscas foram realizadas nas bases de dados Scielo e PubMed. Como palavras-chave foram utilizadas: ofidismo, microbiota, infecções secundárias e abscessos. Os dados epidemiológicos oficiais foram obtidos a partir do sistema eletrônico do SINAN do Ministério da Saúde. A maior incidência de acidentes ofídicos é com serpentes do gênero Bothrops, com uma incidência entre 1 e 20% de infecções secundárias/abscessos. Os resultados indicaram 17 espécies de bactérias isoladas de abscessos derivados de infecções secundárias e 37 espécies identificadas de culturas com material da cavidade oral de serpentes venenosas e não venenosas. Comum a ambos (abscessos e cavidades orais das serpentes venenosas) encontram-se, por ordem de importância (ocorrência em abscessos): Morganella morganii, Escherichia coli, Staphylococcus aureus, Providencia sp., Enterobacter sp., Pseudomonas aeruginosa, Proteus sp. e Klebsiella sp. Existe uma tendência ao uso preferencial do Cloranfenicol como antibiótico de primeira escolha. Entretanto, o aparecimento de cepas resistentes sugere o procedimento de hemoculturas antibiograma, além da antibioticoterapia de amplo espectrol. Palavras-chave: Acidentes ofídicos. Abscessos. Bactérias. Microbiota oral.
