Meningoencephalitis and brain abscessation due to Escherichia coli in a 2 week old alpaca cria 总被引:1,自引:0,他引:1
An alpaca cria which received insufficient colostrum, presented with lethargy, anorexia, no passage of faeces and neurological signs. Differential diagnosis included neonatal septicaemia, meningitis and gastrointestinal obstruction. The cria died despite treatment. Necropsy revealed brain abscesses with Escherichia coli in pure culture. The importance of the amount and timing of colostrum intake is discussed. 相似文献

Avian bornaviruses (ABVs) were recently discovered as the causative agents of proventricular dilatation
disease (PDD). Although molecular epidemiological studies revealed that ABVs exist in Japan, no Japanese
isolate has been reported thus far. In this study, we isolated four strains of Psittaciform 1
bornavirus from psittacine birds affected by PDD using QT6 quail cells. To our knowledge, this is
the first report to isolate ABVs in Japan and to show that QT6 cells are available for ABV isolation. These
isolates and QT6 cells would be powerful tools for elucidating the fundamental biology and pathogenicity of
ABVs. 相似文献

The structure of microtubules is essential for the fertilizing ability of spermatozoa. Acetylation of α-tubulin plays an important role in flagellar elongation and spermatozoa motility. Previous reports have suggested that alpha-tubulin N-acetyltransferase 1 (ATAT1) is the main acetyltransferase involved in the acetylation of α-tubulin. Although ATAT1 is reported to express in the testis, no information is available regarding its expression in elongated spermatids, epididymis, and mature spermatozoa. Hence, it remains unclear whether ATAT1 is involved in spermatozoa maturation and capacitation. Therefore, we evaluated the expression of ATAT1 in the mouse male reproductive system using immunostaining and western blotting. Our results showed that ATAT1 was expressed in spermatids during spermiogenesis in mouse testes, but its expression varied according to the seminiferous tubule stage. We observed ATAT1 in the cytoplasm of round spermatids, the flagella of elongated spermatids, and in the cytoplasm of step 16 spermatids, just before its release into the lumen. In addition, ATAT1 was expressed in epithelial cells of the epididymis. In spermatozoa of the cauda epididymis, ATAT1 expression was primarily observed in the midpiece of the spermatozoa. The localization of ATAT1 protein in the male germline was observed during spermiogenesis as well as during spermatozoa maturation. Our results suggest that ATAT1 may be involved in the formation of flagella and in the acetylation process, which has attracted attention in recent years regarding male infertility. 相似文献
