First case of a dog infected with Aspergillus (Phialosimplex) caninus in Australasia     

W Yang  BR Jones  G Rossi  N Stephens  I Arthur  A Merritt 《New Zealand veterinary journal》2020,68(4):231-237

ABSTRACT

Case history: A 2-year-old Rottweiler dog from Perth (WA, Australia) was referred for assessment of a chronic productive cough and weight loss.

Clinical findings: Severely enlarged bilateral superficial cervical lymph nodes and severely enlarged abdominal organs were present. The body condition score was poor and there was moderate muscle wasting. Thoracic and abdominal computed tomography images revealed severe diffuse enlargement of thoracic and abdominal lymph nodes, hepatomegaly and diffuse splenomegaly. A diffuse bronchial pattern with severe multifocal saccular bronchiectasis was identified in the lungs.

Diagnostic findings: Fungal organisms were seen within macrophages on cytological preparations and on histopathological sections of biopsies of the superficial cervical lymph node. Macrophages contained intracytoplasmic, non-filamentous round-to-ovoid organisms, which varied in size from 5–30?µm in diameter with variable morphology. Budding was not observed, and no hyphae were present. Fungal culture of lymph node tissue resulted in growth of Aspergillus (Phialosimplex) caninus which was confirmed by amplification and sequencing of a segment of the 16S-23S rRNA internal transcribed spacer. Concurrent bacterial bronchitis was diagnosed on culture of broncho-alveolar fluid.

Diagnosis: Disseminated aspergillosis caused by Aspergillus caninus.

Clinical relevance: This is believed to be the first report of infection caused by A. caninus in a dog in Australasia. The dog was treated with itraconazole for 7 months and was still alive 7 months after the start of treatment.  相似文献   

Influence of weather on the fibre yield of mesta (Hibiscus sabdariffa) in the north coastal zone of Andhra Pradesh,India     

B. Bapuji Rao  U. Triveni  N. Harisatyanarayana  P. Latha  N. Venugopala Rao  V.U.M. Rao 《Archives of Agronomy and Soil Science》2013,59(7):989-999

Mesta (Hibiscus sabdariffa) is an important fibre crop in the north coastal zone of Andhra Pradesh which accounts for 59% of India's total production of mesta. The area under this crop has reduced dramatically in recent years and in order to understand the contribution of weather to this decline, long-term experimental data (14 years) on mesta cv. AMV-4 and regional crop yields were analysed. Crop yields decreased in seasons when rainfall exceeded 900 mm and maximum temperature remained below 32.0°C during 10–16 weeks after sowing (WAS), which coincided with the active vegetative stage. The average yields of the region were high when seasonal rainfall ranged between 600 and 725 mm. Increased fibre yields were observed when increasing seasonal rainfall coincided with maximum temperatures exceeding 33.5°C. Fibre yields from a long-term experiment showed strong positive correlations with maximum temperature during 6–16 WAS (r = 0.79) and with mean diurnal temperature range (8.6–10.7°C) during 11–19 WAS (r = 0.66). Step-wise regression showed that maximum variability in fibre yield was explained by maximum temperature which could be used to develop models to predict yield at least one month in advance with acceptable accuracy. This prediction could then be used as an input for crop planning and market intelligence.  相似文献

Assessment of mungbean genotypes for durable resistance to Yellow Mosaic Disease: Genotype × Environment interactions          下载免费PDF全文

Yellow mosaic disease (YMD) is the major constraint of mungbean for realizing high productivity worldwide. Moreover, management of disease using YMD‐resistant genotypes is the simplest approach. Therefore, based on a preliminary screening of 220 genotypes during the year 2010 and 2011 at 17 locations, a set of 25 genotypes was further selected to evaluate at six locations over 2 years for identification of more stable resistant genotypes. The genotype and genotype × environment (GGE) analysis indicated that the genotypes and environment effects were significant (P < 0.001) for YMD incidence. Interestingly, the GGE biplot analysis successfully accounted for 74.71 per cent of the total variation with three genotypes (ML 818, ML 1349 and IPM 02‐14) showing high degree of resistance and stability over the locations. Notably, a strong positive association was observed between disease reaction and temperature, relative humidity and rainfall. As crop is grown in diverse growing environments, aforementioned genotypes can be used as stable/durable sources for future breeding programme to develop YMD‐resistant cultivars.  相似文献   

Assessment of different methods of rice (Oryza sativa. L) cultivation affecting growth parameters, soil chemical, biological, and microbiological properties, water saving, and grain yield in rice–rice system

Field experiments were conducted at DRR farm located at ICRISAT, Patancheru, in sandy clay loam soils during four seasons, Kharif 2008, Rabi 2008–2009, Kharif 2009 and Rabi 2009–2010, to investigate growth parameters, water-saving potential, root characteristics, chemical, biological, and microbial properties of rhizosphere soil, and grain yield of rice (Oryza sativa L.) by comparing the plants grown with system of rice intensification (SRI) methods, with organic or organic + inorganic fertilization, against current recommended best management practices (BMP). All the growth parameters including plant height, effective tillers (10–45 %), panicle length, dry matter, root dry weight (24–57 %), and root volume (10–66 %) were found to be significantly higher with in SRI-organic + inorganic over BMP. With SRI-organic fertilization, growth parameters showed inconsistent results; however, root dry weight (3–77 %) and root volume (31–162 %) were found significantly superior compared to BMP. Grain yield was found significantly higher in SRI-organic + inorganic (12–23 and 4–35 % in the Kharif and Rabi seasons, respectively), while with SRI-organic management, yield was found higher (4–34 %) only in the Rabi seasons compared to BMP. An average of 31 and 37 % of irrigation water were saved during Kharif and Rabi seasons, respectively, with both SRI methods of rice cultivation compared to BMP. Further, total nitrogen, organic carbon%, soil dehydrogenase, microbial biomass carbon, total bacteria, fungi, and actinomycetes were found higher in the two SRI plots in comparison to BMP. It is concluded that SRI practices create favorable conditions for beneficial soil microbes to prosper, save irrigation water, and increase grain yield.  相似文献

Discrimination between Oryza malampuzhaensis Krish. et Chand. and Oryza officinalis Wall ex Watt based on RAPD markers and morphological traits     

George Thomas  Latha Joseph  George Varghese  K. Kalyanaraman  Philomena Kuriachan  M.R. Das 《Euphytica》2001,122(1):181-189

Oryza malampuzhaensis, one of the tetraploid taxa of the genusOryza, is geographically restricted to Western Ghats of South India. Its taxonomic status is not well established and is generally treated as a tetraploid race of O. officinalis. Sixty-three morphological traits and 262 random amplified polymorphic DNA (RAPD) markers generated by 23 random decamer primers were used to assess the genetic relationship between O. malampuzhaensis and O. officinalis. Pair wise comparisons based on both RAPDs and morphological traits revealed 60% genetic distance between the two taxa and was significantly higher (p <0.01) than the corresponding intra-specific distances. Cluster and principal component analysis (PCA) of genetic distance estimations based on RAPDs and morphological traits clearly differentiated the two taxa. High frequency of discrete O. malampuzhaensis specific RAPDs (21%) and the significantly higher (p < 0.05) mean number of amplification products per individual in O. malampuzhaensis observed in the study reflect its allopolyploid nature. Low genetic diversity within O. malampuzhaensis revealed by RAPD analysis indicates the recent origin of this taxa. The RAPD analysis further revealed the possibility that the putative ‘C’ genomeprogenitor of O. malampuzhaensis is a close relative of O. officinalis. In addition, amplification products diagnostic to O. malampuzhaensis were identified. The results of the present study clearly demonstrated that the O. malampuzhaensis is a distinct entity, and support the recent conclusion that O. malampuzhaensis has diverged enough to deserve species status. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献
