Estudou-se em 60 corações de suínos sem raça definida, a frequência, a largura, a posição, a topografia e a vasculotopia das pontes de miocárdio, mediante injeção das artérias coronárias com solução de Neoprene látex – 450, fixação em solução aquosa de formol e dissecção. Os resultados obtidos permitiram concluir que: -as pontes de miocárdio ocorrem em 36,36% das peças, em número de 1 a 3, tendo sido identificadas num total de 32; -a largura das pontes variou de 0,2 cm a 1,9 cm com média de 0,75 cm: -a topografia mais frequentemente observada foi na porção média (36,66%), dorsal (31,25%) e ventral (31,25%); -as pontes de miocárdio ocorrem com maior frequência sobre os ramos da artéria coronária direita (65,62%), do que sobre os ramos da artéria coronária esquerda (34,37%).

Abstract:The literature regarding the diversity of ectoparasites and their interaction with their hosts remains largely inadequate in Malaysian tropical rainforest. We investigate the interaction patterns and specialization of ectoparasites infesting terrestrial small mammals (rodents and scandents) in Peninsular and Malaysian Borneo from samples made in 16 localities between 2008 and 2010. A total of 3,235 individuals of ectoparasites were collected during field surveys, resulting in an interaction network involving 47 ectoparasites that were distributed on 23 species of small mammals. The overall specialization index H 2 ' of all ectoparasites and host species was 0.67 which was considered moderate. Ticks appeared to be generalist with specialization index (H 2 ' = 0.35) while lice showed higher specialization (H 2 ' = 1) in selecting host species. The most diverse parasite assemblage was found on S. muelleri (H s_w = 1.96). Specialization indices among ectoparasite species (d p ) ranged from 0.03 to 1 while the indices among host species (d h ) ranged from 0.20 to 1. Incomplete field data may have contributed to the high specialization indices. This study is significant as it can enhance our understanding the emergence and management of potential zoonotic diseases in Malaysia.

http://dx.doi.org/10.5007/2175-7925.2009v22n4p163The asinine species was originated thousands of years ago from the same branch of domestic equine. Asinines have been undergoing a great adaptation resulting in different characteristics observed in their populations around the world. In the northeastern region of Brazil, they play an essential role in the economy of local families. Due to a large number of locomotor disorders and a lacN of professional care for these animals, a radiographic study of the distal forelimb region of the asinine was carried out in order to gather information for the improvement of clinical and surgical practices in this species, and to explain their low susceptibility to locomotor disorders compared to that of the domestic equine. The angiographic examination revealed the main arterial vessels committed to the blood supply of the forelimbs in these animals, providing evidence of the vascular pattern of the median and palmar common digital arteries, which originated a great number of collateral branches, mainly to the distal phalanx. The distal forelimbs in donNeys have shown great vascular anastomosis, promoting additional blood supply to the deep endosteum and periosteum regions, probably as a response to the physical activity developed by these animals.

Both the acarine species found on the Burmese pythons are known vectors of pathogens. This is the first record that R. sanguineus has been reported from a pet Burmese python in Malaysia.

Utilizando 35 pares de funículos esperméticos de eqüinos sem raça definida, estudaram-se os aspectos histológicos dos envoltórios funiculares, dos vasos arteriais e venosos e dos tecidos intervasculares, assim como o seu arranjo vascular e o comprimento do segmento da artéria testicular nele contido.

Mite biodiversity and distribution in Malaysia is currently understudied. Most previous works on Malaysian Acari have focused on pest organisms of medical, veterinary, and agricultural concern, with a few recent studies centered on mites in forensic contexts. Previous literatures have targeted collection sites in forest reserves and/or mountains in either Peninsular or Malaysian Borneo, though the state of Sarawak had the least publications related to mite species descriptions despite having the highest number of nature parks of any state in the country. Most publications focused on the three states Selangor, Pahang and Sabah. Most of the mite species reported were from mammals (66.3%), with fewer species from birds (21.7%), arthropods (11.2%), and reptiles (0.8%). We believe that further work on the systematic documentation of mite species throughout Malaysia is necessary as it could generate useful tools, such as the use of mites as biogeographical markers or as forensic indicators. Therefore, this review catalogs mite species that have been documented in or on animal hosts in Malaysia and serves as a foundation for future work.
