Title : Identification of bacterial isolates collected from fresh water fish Material Type: printed text Authors: Prasad, S., Author ; Rayamajhi, A., Author Pagination: 369-372 p. Languages : English (eng) Keywords: Aeromonas hydrophila, bacterial isolates, causative agent Abstract: Bacterial diseases are among the most important and common problems faced by aquaculturist worldwide. Identification and treatment of causative agent based on gross sign are sometimes not very effective because several isolates of the pathogens are associated with other aquatic vertebrate diseases. In this study, bacterial isolates were isolated from two different places, FRD Godawari and FRC Pokhara and diagnosed by obtaining pure culture followed by phenotypic test (morphological, physiological and biochemical test) and compared with existing diagnostic scheme. Based on certain uniformity such as Gram-negative and positive reactions for catalase, oxidase and fermentative reaction on glucose enables to identify the isolates, Aeromonas hydrophila. Some sugar utilization and decarboxylase test showed differences in strains of Aeromonas hydrophila.

Title : Participatory Evaluation of Some Tomato Genotypes for Resistance to Bacterial Wilt Material Type: printed text Authors: Timila (Dhawa), R.D., Author ; Sharada Joshi, Author Publication Date: 2007 Article on page: 50-55 p Languages : English (eng) Keywords: Bacterial wilt, Ralstonia solanacearum, resistant variety, Tomato Abstract: Bacterial wilt caused by Ralstonia solanacearum E.F. Smith is one of the destructive
diseases of tomato. Experiments were conducted to confirm the resistance and to evaluate
varieties received from Asian Vegetable Research and Development Center against bacterial
wilt disease in the farmers’ bacterial wilt sick fields at Thaiba and at Panchkhal during 1999
and 2000-2001 respectively. A total of five varieties such as CLN 2026 C, CLN 2026 D,
CLN 1466 J, CLN 1466 P and susceptible check Lapsigede or L 390 were included in the
experiments. Randomized complete block design with 4 replications was commenced at
both the locations. In terms of disease incidence and yield parameters as well as consumers’
preference on the fruit size, CLN 2026 C was found the best variety followed by CLN 2026
D. Wilt incidence was significantly lower in those varieties showing resistant reaction than
in susceptible check. However, the marketable fruit yields were significantly higher with
low wilt incidences in CLN 1466 P and CLN 1466 J also compared to susceptible check.
But the large fruit size of those varieties was not acceptable to the consumers and the
growers. Thus, CLN 2026 C and CLN 2026 D could be used as resistant variety to minimize
crop losses from bacterial wilt disease.Link for e-copy: http://elibrary.narc.gov.np/?r=27

Title : Evaluation of rice genotypes for resistance to bacterial blight Material Type: printed text Authors: B. Chaudhary ; M Yadav, Author ; Yadaw, R.B., Author ; DB Gharti, Author ; Akhtar, T., Author ; Bhandari, D., Author Pagination: 344-348 p. Languages : English (eng) Keywords: Bacterial blight ; rice lines resistance locations pathotypes Abstract: A total of 244 rice lines in 2002 with a diverse genetic background and 248 in 2003 were
tested for resistance to bacterial blight (BB) over locations. Disease severity ranged from 0
to 9 in both the years. Genotypes differed in disease reaction to BB over locations. During
2002, 4 genotypes scored resistant (R), 104 moderately resistant (MR), 101 moderately
susceptible (MS), 46 susceptible (S) and 19 highly susceptible (HS) to BB at Hardinath. At
Parwanipur, 201 genotypes rated immune. 36 R, 25 MR. and 10 MS to BB. At Bhairahawa, 3
genotypes showed R, 146 MR. 75 MS. 37 Sand 13 HS to BB. During 2003, 3 genotypes
registered R. 112 lv!R. 82 MS, 42 Sand 23 HS to BB at Hardinath while 16 entries did not
germinate. At Parwanipur, 85 enrries were immune, 109 R, 53 MR and 17 MS to BB while 13
entries failed to germinate. At Bhairahawa, 3 entries recorded R, 51 MR. 62 MS, 65 Sand 97
HS to disease. However, 58 and 22 genotypes were R to MR over locations during 2002 and
2003 tests, respective~v. This showed that there was prevalence of variable pathotypes over
locations and thus, genotypes need to be tested over locations to identify donor parents and
resistant genotypes for recommendation.
Out of 216 genotypes including standard and local r;hecks received from International Rice
Research Institute. 45 entries were R, 92 MR. 49 MS. 23 S and 4 HS to BB in 2003 test at
Hardinath, and the rest 3 entries did not germinate.Link for e-copy: http://elibrary.narc.gov.np/?r=1121 Evaluation of rice genotypes for resistance to bacterial blight [printed text] / B.

Title : Characteristics of Ralstonia Solanacearum Strains of Potato Wilt Disease from Nepal and Thailand Material Type: printed text Authors: Dhital, S.P., Author ; N. Thaveechai, Author ; Sundar K. Shrestha, Author Publication Date: 2000 Article on page: 42-47 p Languages : English (eng) Keywords: Key words: Bacterial wilt, potato, Pseudomonas solanacearum, Ralstonia solanacearum Abstract: Characterization of strains of Ralstonia solanacearum, the causal agent of potato bacterial wilt
disease from Nepal and Thailand was performed based on pathogenicity,
biochemical/physiological and serological tests. Fifteen R. solanacearum strains isolated from wilt
infected potato plants and tubers grown in Nepal were characterized as race 3, biovar II based on
the pathogenicity on different host plants, hypersensitive reaction on tobacco leaf and utilization of
some sugars. Results of pathogenicity test show that all strains from Nepal had limited host range.
Degree of virulence of all strains varied from high to medium in potato and tomato and medium to
low in eggplant. They did not cause wilting in tobacco, pepper and peanut plants. Six strains from
Thailand were characterized as biovar II and III. Additionally, comparisons on the physiological,
biological and serological characters of seven strains from Nepal and six from Thailand revealed
similar characters. Race 3 and biovar II of the pathogen was widely spread over potato growing
areas of mid and high hills of Nepal. Both biovars II and III were prevalent in the potato growing
areas of Thailand but biovar III was the most dominating one.Link for e-copy: http://elibrary.narc.gov.np/?r=92
