Coral Snake (Micrurus Fulvius Fulvius) Envenomation In Five Dogs: Present And Earlier Findings

The purpose of this study is to report on five cases of coral snake envenomation in the dog to substantiate earlier findings in four dogs reported previously, and to describe any additional clinical features that have not yet been noted. The combined results from both studies allow for a more accurate projection of the frequency of certain clinical signs. Both groups showed signs of lethargy, lower motor neuron weakness (8 of 9 dogs) and varying hematologic changes with hemolysis and hemoglobinuria occurring most commonly (7 of 9 dogs). Cardiac dysrhythmias were recorded infrequently (2 of 9 dogs). Not reported previously was the presence of a subtle bite wound located on the upper or lower lip of three dogs in the present series. An unexpected finding in this second series was the occurrence of an anaphylactoid reaction in one dog presumably attributed to the antivenin. Close examination of the lip might reveal the site of envenomation (as found in 4 of 9 dogs from both studies). Treatment with coral snake antivenin should be given as early as possible and followed by close observation for signs of anaphylaxis. The results of this study substantiate earlier findings and provide for a larger data base for further reference.     

野生无刺蜂诱桶引诱分群方法及应用

无刺蜂（Stingless bees）是分布在热带、亚热带地区的一类重要授粉昆虫。野生无刺蜂蜂群通常在树洞、墙洞、崖壁石缝等区域内筑巢,获取野生蜂群通常会破坏其筑巢环境、甚至会破坏蜂群。在我国,无刺蜂仅分布在云南、海南等少数热带及亚热带区域。为了维持野生无刺蜂的种群数量,保证无刺蜂产业的健康、可持续发展,介绍了主动诱导法和被动诱导法2种野生无刺蜂群诱桶使用方法,并讨论了诱桶方法使用中的注意事项和优劣。以期推广该方法来保护野生无刺蜂蜂群、栖息地及环境。     

Thrombotest (PIVKA) Test Results in 25 Dogs with Acquired and Hereditary Caogulopathies

In the veterinary literature, it has been suggested that a prolongation in the thrombotest (PIVKA test) is a sensitive and diagnostic indicator of anticoagulant rodenticide intoxication. We evaluated prothrombin time (PT), activated partial thromoplastin time (aPTT), and PIVKA indicator in 25 bleeding dogs: 7 with inherited coagulopathies. All dos with acquired coagulopathies had prolonged PIVKA values when compared to the normal controls. Factor VII deficient dogs had a prolonged PIVKA and PT test result, whereas dogs with intrinsic coagulopathies only had an aPTT prolongation. A three-fold increase of the PIVKA or PT values was highly suggestive of an anticoagulant rodenticide poisoning compared to other acquired coagulopathies. Prolonged PIVKA resuls were not specific for anticoagulant rodenticide intoxication in our group of bleeding dogs.     

An accidental fatal attack on domestic pigeons by honey bees in Bangladesh

Fatalities among avian species due to multiple bee stings are rare. Sixteen pigeons on a farm in Bangladesh each suffered multiple bee stings. Ten of the pigeons died before treatment, 5 (4–11 stings) died within 12 hr after treatment, and 1 pigeon (only 3 stings) survived. Body temperature, heart rate, respiratory rate, hematocrit, hemoglobin, erythrocytes, thrombocytes, MCV, MCH and MCHC decreased significantly after the incident, but leucocytes, heterophils, basophils, eosinophils, monocytes, ALT, AST, LDH, CK, creatinine, BUN and UA increased markedly. Overall, the hematological and biochemical changes in the bee-stung pigeons were similar to those of mammals; however, avian species may be more sensitive to bee stings than mammals.
