In March 2021, severe signs of powdery mildew were observed on leaves and stems Coccinia grandis in the Manchar, Pune District, Maharashtra state, India. Based morphological examination, phylogenetic analyses, pathogenicity test, causal agent was identified as Golovinomyces tabaci. To our knowledge, this is first record G. tabaci infecting C. Previously, had only been reported from Taiwan Thail...

Aeromonas infections are becoming a major risk factor in commercial aquaculture and it has been reported that a wide variety of fish and shellfish species are susceptible to this infection. In this study, 3 isolates of Aeromonas hydrophila were isolated from giant freshwater prawn (Macrobrachium rosenbergii) cultured in Kuala Pilah Simbilan Nigri in East Malaysia. Conventional and rapid identif...

in this study, the pathogenicity of a/ch/it/5093/1999 h7n1 which had been isolated from chicken during the outbreak in italy was assessed in chicken by experimental infection virus. ten spf chickens of four week-old were inoculated with this virus, and five chickens were inoculated with uninfected allantoic fluid. for determination of virus shedding, oropharyngeal and cloacal swabs were taken f...

We assessed Aichi virus shedding in patients with gastroenteritis and negative test results for other viral and bacterial infections. High concentrations of up to 1.32 × 1012 RNA copies/g stool were found in 10 (2.0%) of 499 outpatients sampled in northern Germany, 2004. These data substantiate Aichi virus pathogenicity in humans.

The objective of this work was to evaluate the efficiency of noni essential oil on the control of Exserohilum turcicum, a causative agent of Exserohilum spot in maize culture. In the sanitary test 400 seeds were incubated using the blotter test method. For the transmissibility test, the fragments of damaged leaves of seedlings were removed and put into a potato, dextrose and agar (PDA) culture ...

Seroprevalence of Crimean-Congo hemorrhagic fever virus (CCHFV) is high in some regions of Greece, but only 1 case of disease has been reported. We used 4 methods to test 118 serum samples that were positive for CCHFV IgG by commercial ELISA and confirmed the positive results. A nonpathogenic or low-pathogenicity strain may be circulating.

To determine possible cosavirus association with clinical disease, we used real-time reverse transcription PCR to test children and HIV-positive adults in Brazil with and without gastroenteritis. Thirteen (3.6%) of 359 children with gastroenteritis tested positive, as did 69 (33.8%) of 204 controls. Low prevalence, frequent viral co-infections, and low fecal cosavirus RNA concentrations argue a...

Type III secretion (TTSI) genes of an HRP (hypersensitivity response and pathogenicity)-like locus were present in all 116 Northern Australian Burkholderia pseudomallei isolates tested but were not detected in other common environmental Burkholderia species. PCR of TTS1 genes may prove valuable as a diagnostic test [corrected].
