Corneal lesions appearing as white mass beneath intact epithelium, with ocular discharge in one mouse, was observed in a batch of laboratory-raised BALB/c mice (n=9 of 56). The affected mice remained active, well-groomed and had normal appetite. Isolates recovered from swab cultures of the external and internal contents of the eye had partial 16S rRNA gene sequence of 99.1% similarity to Streptococcus cuniculi. No previous report of S. cuniculi infection in laboratory rodents has been presented. The isolate was susceptible to all antibiotics tested. We suggest S. cuniculi is an opportunistic bacteria in laboratory mice but are uncertain of its source. Our findings revealed that S. cuniculi is able to colonize laboratory mice and should be considered when mice present with eye lesion or ocular discharge. 相似文献

Orf virus (ORFV), a member of parapoxvirus, is an enveloped virus with genome
of double-stranded DNA. ORFV causes contagious pustular dermatitis or contagious ecthyma
in sheep and goats worldwide. In general, detection of viral DNA and observing ORFV virion
in tissues of afflicted animals are two methods commonly used for diagnosis of orf
infection; however, isolation of the ORFV in cell culture using virus-containing tissue as
inoculum is known to be difficult. In this work, the ORFV (Hoping strain) isolated in
central Taiwan was successfully grown in cell culture. We further examined the biochemical
characteristic of our isolate, including viral genotyping, viral mRNA and protein
expression. By electron microscopy, one unique form of viral particle from ORFV infected
cellular lysate was demonstrated in the negative-stained field. Moreover, immunomodulating
and anti-influenza virus properties of this ORFV were investigated. ORFV stimulated human
monocytes (THP-1) secreting proinflammatory cytokines IL-8 and TNF-α. And, pre-treatment
of ORFV-infected cell medium prevents A549 cells from subsequent type A influenza virus
(IAV) infection. Similarly, mice infected with ORFV via both intramuscular and
subcutaneous routes at two days prior to IAV infection significantly decreased the
replication of IAV. In summary, the results of a current study indicated our Hoping strain
harbors the immune modulator property; with such a bio-adjuvanticity, we further proved
that pre-exposure of ORFV protects animals from subsequent IAV infection. 相似文献

At Onne in South-east Nigeria, drainage water was collected from four monolith lysimeters and analysed for nitrate. The lysimeters contained an acid sandy loam. At the start of the first rainy season two lysimeters received urea labelled with 15 NO3 – and two received no nitrogen fertilizer; all four were uncropped in the first year.
The peak concentrations of15 NO3 – and of unlabelled (soil) NO3 – were found after 2.5 pore volumes of water had passed through the lysimeters. Using the same soil in the laboratory after fine sieving, the peak concentration of tritiated water was found at 1 pore volume whereas nitrate leaching was retarded. The pattern of nitrate leaching was well described by miscible and immiscible models which included an adsorption coefficient for nitrate. Over the 2 years 81.4% of the 15 N added at the start of the first rainy season was recovered in the drainage water. 相似文献

The life history of Tenualosa macrura in Sarawak, further notes on protandry in the genus and management strategies 总被引:1,自引:0,他引:1
S. J. M. BLABER G. FRY D.A. MILTON T. VAN DER VELDE O. BOON-TECK J. PANG & P. WONG 《Fisheries Management and Ecology》2005,12(3):201-210
Abstract The contraction of Tenualosa macrura (Bleeker) to the Sarawak coast and a small part of Sumatra, and the decline in its fishery mirror what has happened to three other species in the genus. Little was known of this species in its last stronghold in Sarawak where it is important for management and conservation reasons to understand its biology and life history. It forms part of a multispecies fishery where effort is uniform, but catches follow a lunar cycle. Tenualosa macrura is protandrous, but low numbers of small females suggest diandry. In Sumatra Tenualosa macrura spawn throughout the year, but in Sarawak have a seasonal peak in the NE monsoon (December). This has management implications because the Sarawak fishery ceases at this time because of adverse weather, hence reducing fishing pressure on spawning T. macrura . Management measures introduced in Sarawak for Tenualosa toli (Valenciennes) may therefore not be required for T. macrura . 相似文献

In addition to the electronic factors, there is a steric factor responsible for the carcinogenicity of polynuclear aromatic hydrocarbons. A carcinogenic polynuclear aromatic hydrocarbon must bear steric resemblance to steroids. One possible implication to this requirement for carcinogenicity is that these hydrocarbons may act on the same sites as steroid hormones. 相似文献

Clinical investigations of halothane and isoflurane for induction and maintenance of foal anesthesia
E. P. STEFFEY N. WILLITS P. WONG S. V. HILDEBRAND J. D. WHEAT D. M. MEAGHER D. HODGSON † J. R. PASCOE R. B. HEATH ‡ C. DUNLOP ‡ 《Journal of veterinary pharmacology and therapeutics》1991,14(3):300-309
Fifty-eight foals were divided into two groups for study of aspects of the clinical anesthetic management of foals and to characterize effects of halothane (n = 30) and isoflurane (n = 28) in foals. There were no significant differences (P greater than 0.05) in the demographics of the two groups. Results of hemograms and biochemical analysis of venous blood samples before and after anesthesia were either not influenced or only mildly (clinically unimportant) affected by either agent. Like adult horses, foals have an increased PaCO2 when anesthetized with inhaled anesthetics. We could detect no difference in the magnitude of increase in PaCO2 with either anesthetic. Anesthetic induction and recovery was most rapid with isoflurane. The quality of induction and recovery was similarly acceptable with either agent. Heart rate during isoflurane was not significantly different from conscious conditions but during halothane, heart rate was significantly less than control except at 91-120 min when statistical significance was not detected. These results support the clinical impression that foals can be safely and reliably anesthetized with either agent. 相似文献
