AB  - Bacterial stalk soft rot have been repeatedly observed on maize plants in several commercial fields in northern part of Serbia in the period of 1990 to 2014. The occurrence of the disease corresponded with warm weather and increased humidity. Etiological studies of the diseased tissue constantly resulted in isolation of pectolytic bacterial strains. In order to identify the isolated bacteria, twenty-three strains were characterized by morphological, physiolcal, biochemical, and molecular assays. Pathogenicity of the strains was confirmed by Koch's postulates on 1-week-old maize seedlings. The strains were Gram and oxidase-negative, non-fluorescent, pectolytic, facultative anaerobic and caused hypersensitive response (HR) in tobacco leaves. They produced catalase and lecithinase, but did not produce oxidase and arginine dehydrolase. All strains reduced nitrate and grew at 37 degrees C, while variable growth was observed in medium containing 5% NaCl. Phenotypic tests and amplification of the specific 420-bp fragment in PCR assay showed that the strains belong to genus Dickeya. Using ERIC-PCR analysis seven different genetic profiles were obtained, suggesting the presence of genetic diversity in the population of this pathogen in Serbia. Additionally, phylogenetic analysis based on the recA gene sequence analysis indicated that the strains isolated from soft rotted maize belong to Dickeya zeae, leading to the conclusion that this bacterium was the causal agent of stalk soft rot of maize in Serbia.

AB  - Three PCR methods, referred in this study as,conventional" "nested" and,chromosomal" PCR and suggested for routine detection of Erwinia amylovora in pure culture and plant material, were evaluated according to their specificity and sensitivity. Specificity of PCR methods was analyzed by using 42 strains of E. amylovora, originating from different locations and plant species, with diverse PFGE profiles, representing distant populations of the pathogen. Sensitivity of PCR protocols in pure culture was studied by using nine different concentrations of E. amylovora in sterile ultrapure water as a template in PCR reactions. In order to study inhibitory effect of plant DNA and other inhibitors on sensitivity of the three PCR methods bacterial dilutions were mixed with plant macerate of pear, apple and quince prior to the PCR reaction. In specificity assays, tested PCR protocols were able to detect all E. amylovora strains regardless of the host of the strain, its origin or PFGE group, indicating primer specificity. On the other hand, sensitivity among tested methods varied, depending on bacterial concentration and selected plant material used in the PCR. When working with pure cultures nested PCR showed the greatest sensitivity by detecting 1.9 bacterial cells per PCR reaction, followed by detection limit of 9.5 cells per PCR reaction with conventional PCR and 1.9.105 cells/PCR reaction with chromosomal PCR. In spiked samples plant inhibitors either did not affect or they decreased the sensitivity of the PCR reaction, depending on the protocol and/or type of plant macerate. In our experiments, inhibitors from pear and quince macerates did not affect sensitivity of nested PCR, while apple macerate reduced its sensitivity by a factor of 10. Conventional PCR protocol was able to detect 95 cells/PCR reaction in pear and apple macerate, but only 9.5.103 cells/PCR in quince macerate. Greatest decrease in sensitivity of the PCR method was observed in spiked samples with chromosomal PCR since bacterial DNA was not detected in each of the spiked samples. Our research shows that all three PCR protocols are specific for detection of E. amylovora, but nested PCR proved to be most sensitive when working with pure cultures and plant material.

AB  - The diversity of 30 Erwinia amylovora strains, isolated from quince, pear and apple trees on 14 localities in Serbia, was studied using bacteriological and molecular methods. In pathogenicity tests, all strains caused necrosis and oozing of bacterial exudate on inoculated immature pear, cherry and plum fruits, and induced hypersensitive reaction in tobacco leaves. The studied strains were Gram and oxidase negative, non-fluorescent, levan and catalase positive and facultatively anaerobic. The strains did not reduce nitrates, but utilized citrate and produced acid from sorbitol, hydrolyzed gelatine, produced reducing substances from sucrose and grew in the presence of 5% NaCl, but not at 36oC. Identity of the strains was confirmed by conventional and nested PCR methods. Rep-PCR with REP, ERIC and BOX primers resulted in amplification of several DNA fragments respectively, but showed no variation within the strains. However, different genetic profiles were obtained with RAPD-PCR by using six primers which enabled differentiation of the strains into four groups. Genetic differences between the studied strains did not correlate with the host plants, geographical origin or year of isolation.
AB  - Primenom standardnih bakterioloških i molekularnih metoda proučen je diverzitet 30 sojeva Erwinia amylovora izolovanih iz dunje, kruške i jabuke, poreklom iz 14 lokaliteta u Srbiji. Svi proučavani sojevi izazvali su nekrozu i pojavu bakterijskog eksudata na nesazrelim plodovima kruške, trešnje i šljive, kao i hipersenzitivnu reakciju duvana. Proučavani sojevi bili su Gram i oksidaza negativni, fakultativno anaerobni, levan i katalaza pozitivni i nisu stvarali fluorescentni pigment na Kingovoj podlozi B. Svi sojevi hidrolizuju želatin, koriste citrate i stvaraju kiselinu iz sorbitola, proizvode redukujuće supstance iz saharoze, ne redukuju nitrate, razvijaju se u prisustvu 5% NaCl, ali ne i pri 36°C. Identitet sojeva potvrđen je konvencionalnim PCR i nested PCR metodama. Rep-PCR metodom korišćenjem REP, ERIC i BOX prajmera umnoženo je više fragmenata DNK čiji broj i veličina su se podudarali kod svih proučavanih sojeva. Za razliku od Rep-PCR, primenom RAPD-PCR metode uz korišćenje šest prajmera došlo je do izdvajanja različitih genetičkih profila i diferencijacije sojeva u četiri grupe. Genetičke razlike među proučavanim sojevima nisu bile u korelaciji sa domaćinima iz kojih su izolovani, niti sa njihovim geografskim poreklom i godinom izolacije.

AB  - Xanthomonas euvesicatoria phage K Phi 1, a member of Myoviridae family, was isolated from the rhizosphere of pepper plants showing symptoms of bacterial spot. The phage strain expressed antibacterial activity to all X. euvesicatoria strains tested and did not lyse other Xanthomonas spp., nor other less related bacterial species. The genome of K Phi D1 is double-stranded DNA of 46.077 bp including 66 open reading frames and an average GC content of 62.9%, representing the first complete genome sequence published for a phage infecting xanthomonads associated with pepper or tomato. The highest genome similarity was observed between phage K Phi 1 and the Xanthomonas oryzae pv. oryzae specific phage OP2. On the other hand, when compared with other members of the genus Bcep78virus, the genome similarity was lower. Forty-four (67%) predicted K Phi 1 proteins shared homology with Xanthomonas phage OP2, while 20 genes (30%) were unique to K Phi 1. Phage K Phi 1, which is chloroform resistant and stable in different media and in the pH range 5-11, showed a high titer storage ability for at least 2 years at +4 degrees C. Copper-hydroxide and copper-oxychloride reduced phage activity proportionally to the used concentrations and the exposure time. UV light was detrimental to the phage strain, but skim milk plus sucrose formulation extended its survival in vitro. The phages survived for at least 7 days on the surface of pepper leaves in the greenhouse, showing the ability to persist on the plant tissue without the presence of the host bacterium. Results of three repeated experiments showed that foliar applications of the unformulated K Phi 1 phage suspension effectively controlled pepper bacterial spot compared to the standard treatment and the untreated control. The integration of the phage K Phi 1 and copper-hydroxide treatments resulted in an increased efficacy compared to the copper-hydroxide alone.

AB  - Cucurbits production has a long tradition in our country. In some parts of the country, cucumber, watermelon and melon are the most important agricultural crops. High yield and good profit are often compromized by various biotic and abiotic factors. In years with favorable weather conditions cucurbit bacterial diseases can cause serious damage. This paper describes major bacterial diseases of cucurbit plants, such as angular leaf spot caused by Pseudomonas syringae pv. lachrymans, bacterial fruit blotch caused by Acidovorax citrulli, bacterial spot caused by Xanthomonas campestris, bacterial wilt caused by Erwinia tracheiphila and cucurbit yellow wine disease caused by Serratia marcescens, relatively new and invasive disease across the United States. In addition, bacterial leaf spot, caused by Pseudomonas syringae pv. syringae and Pectobacterium carotovorum subsp. carotovorum, inducing bacterial soft rot, are becoming more important in cucurbit production worldwide.
AB  - Biljke familije Cucurbitaceae se dugi niz godina gaje širom naše zemlje. U pojedinim krajevima, proizvodnja krastavca, lubenice i dinje predstavlja osnovni izvor prihoda za mnoga poljoprivredna domaćinstva. Visok prinos i ekonomsku dobit često ugrožavaju različiti biotski i abiotski faktori. U godinama sa uslovima povoljnim za nastanak infekcije, bakteriozna oboljenja mogu prouzrokovati velike gubitke. U ovom radu predstavljene su najznačajnije bakterioze biljaka familije Cucurbitaceae kao što su uglasta pegavost lišća krastavca, prouzrokovana bakterijom Pseudomonas syringae pv. lachrymans; bakteriozna mrljavost plodova lubenice, čiji je prouzrokovač Acidovorax citrulli; zatim bakteriozna pegavost koju prouzrokuje Xanthomonas cucurbitae; bakteriozna uvelost krastavca prouzrokovana vrstom Erwinia tracheiphila i žutilo vreža, čiji je prouzrokovač Serratia marcescens. Gubicima u proizvodnji doprinose i prouzrokovači bakteriozne pegavosti, Pseudomonas syringae pv. syringae, kao i bakteriozne vlažne truleži, Pectobacterium carotovorum subsp. carotovorum.

Visok prinos i ekonomsku dobit često ugrožavaju različiti biotski i abiotski faktori. U godinama sa uslovima povoljnim za nastanak infekcije, bakteriozna oboljenja mogu prouzrokovati velike gubitke. U ovom radu predstavljene su najznačajnije bakterioze biljaka familije Cucurbitaceae kao što su uglasta pegavost lišća krastavca, prouzrokovana bakterijom Pseudomonas syringae pv. lachrymans; bakteriozna mrljavost plodova lubenice, čiji je prouzrokovač Acidovorax citrulli; zatim bakteriozna pegavost koju prouzrokuje Xanthomonas cucurbitae; bakteriozna uvelost krastavca prouzrokovana vrstom Erwinia tracheiphila i žutilo vreža, čiji je prouzrokovač Serratia marcescens. Gubicima u proizvodnji doprinose i prouzrokovači bakteriozne pegavosti, Pseudomonas syringae pv. syringae, kao i bakteriozne vlažne truleži, Pectobacterium carotovorum subsp. carotovorum.",

AB  - During the summer of 2014, watermelon producers in the north of Serbia (Srem district), observed the occurrence of irregularly shaped, water-soaked lesions on mature watermelon fruits indicating possible bacterial nature of the disease. Bacteria were isolated from symptomatic samples and identified as Acidovorax citrulli, previously described as a causal agent of bacterial fruit blotch. In the past few years, this pathogen caused considerable damage to the watermelon industry of the United States where, in some commercial production sectors, the loss of marketable fruit reached 90%. In Serbia, it is considered a quarantine pathogen and was not recorded until 2014.
AB  - U leto 2014. godine, proizvođači lubenice iz sremskog okruga uočili su pojavu simptoma u vidu pega vodenastog izgleda i nepravilnog oblika na zrelim plodovima lubenice, koji su ukazivali na oboljenje bakteriozne prirode. Izolacijom i identifikacijom patogena, utvrđeno je prisustvo bakterije Acidovorax citrulli, prouzrokovača bakteriozne mrljavosti plodova lubenice. Ova vrsta je u skorije vreme dosta dobila na značaju, posebno zbog gubitaka u proizvodnji koji su u pojedinim oblastima Sjedinjenih Američkih Država (SAD) dostizali i 90% od ukupnog prinosa. U Srbiji A. citrulli ima karantinski status i nalazi se na A1 listi Evropske i mediteranske organizacije za zaštitu bilja (EPPO).

AB  - During the last 3 years, crown gall disease was observed in some young raspberry plantations throughout Serbia, causing considerable economic losses. Based on biochemical and physiological tests, PCR targeting the 23S rRNA gene, and 16S rRNA and recA gene sequence analysis, at least two different species were identified as causal agents of disease. Out of 14 strains isolated from raspberry tumors, 12 were identified as tumorigenic Rhizobium rhizogenes, one belonged to Agrobacterium tumefaciens genomic species G8, while the remaining strain formed a separate phylogenetic lineage within A. tumefaciens species complex, different from all known genomic species. All strains investigated harbored nopaline-type of Ti plasmid and showed identical pathogenic properties by inoculating several test plants. However, they were divided into two genetic groups based on PCR-RFLP analysis of Ti plasmid virA-virB2 region. Furthermore, total of nine unique ERIC-PCR profiles were identified among the strains studied. Although strains of R. rhizogenes exhibited similar ERIC-PCR profiles, they were differentiated into six distinct genetic groups. Based on the fact that some genetic groups were composed of strains originating from different geographic areas, it can be assumed that they have a common origin and were probably disseminated by movement of infected plant material.

AB  - Serious outbreaks of grapevine crown gall disease were observed in major Serbian viticultural regions during the last five years. Tumorigenic Agrobacterium vitis was identified as a causal agent by using conventional bacteriological and molecular tests. The 36 studied strains of A. vitis showed homogeneous biochemical and physiological characteristics, but were heterogeneous in their pathogenic properties, especially on tomato and sunflower. Furthermore, genetic differences related to chromosomal and plasmid DNA were observed. The Ti plasmid of 35 strains was classified as the octopine/cucumopine (O/C) type, whereas one was classified as the vitopine (V) type. The O/C strains were further divided into O/C-1 and O/C-2 groups based on PCR analysis. Moreover, the sequence analysis of the 16S-23S rRNA ITS region provided robust and precise delineation of studied strains. Although a high level of genetic diversity in A. vitis strains from Serbia was revealed by using this approach, their genotypic relatedness with the strains from other countries suggested their common origin. Also, association between the chromosomal and plasmid DNA was determined for some phylogenetic groups and clusters.

AB  - Bacteriophages are viruses that infect bacteria. Due to poor efficacy of copper compounds and occurrence of antibiotic resistant bacterial strains, interest in phage therapy has increased in the recent years. In addition to being used for disease control, the high specificity of bacteriophages makes them useful in differentiation of closely related species of plant pathogenic bacteria. In this research, twenty five phages, specific to Xanthomonas euvesicatoria, causal agent of pepper bacterial spot, were isolated. Host specificity determination performed with 53 phages from University of Florida collection resulted in set of phages which could be used for differentiation of X. euvesicatoria, X. perforans, X. vesicatoria and X. gardneri.
AB  - Bakteriofagi predstavljaju posebnu grupu virusa čiji su domaćini bakterije. Usled nedostatka efikasnih baktericida i pojave rezistentnih sojeva bakterija prema većini do sada korišćenih antibiotika, primena faga kao bioloških agenasa u kontroli bolesti prouzrokovanih fitopatogenim bakterijama, dobija sve veći značaj. Zahvaljujući izraženoj specifičnosti, fagi se osim za suzbijanje koriste i za diferencijaciju srodnih vrsta fitopatogenih bakterija. U ovom radu izolovano je 25 faga specifičnih prema vrsti Xanthomonas euvesicatoria, prouzrokovaču bakteriozne pegavosti paprike. Fagi su izolovani iz uzoraka zemljišta, vode i semena paprike poreklom iz različitih lokaliteta u Srbiji. Pored faga izolovanih u Srbiji, proverena je specifičnost 53 soja dobijenih iz kolekcije Univerziteta u Floridi i izdvojen set faga koji se mogu koristiti u diferencijaciji vrsta X. euvesicatoria, X. perforans, X. vesicatoria i X. gardneri.

In this research, twenty five phages, specific to Xanthomonas euvesicatoria, causal agent of pepper bacterial spot, were isolated. Host specificity determination performed with 53 phages from University of Florida collection resulted in set of phages which could be used for differentiation of X. euvesicatoria, X. perforans, X. vesicatoria and X. gardneri., Bakteriofagi predstavljaju posebnu grupu virusa čiji su domaćini bakterije. Usled nedostatka efikasnih baktericida i pojave rezistentnih sojeva bakterija prema većini do sada korišćenih antibiotika, primena faga kao bioloških agenasa u kontroli bolesti prouzrokovanih fitopatogenim bakterijama, dobija sve veći značaj. Zahvaljujući izraženoj specifičnosti, fagi se osim za suzbijanje koriste i za diferencijaciju srodnih vrsta fitopatogenih bakterija. U ovom radu izolovano je 25 faga specifičnih prema vrsti Xanthomonas euvesicatoria, prouzrokovaču bakteriozne pegavosti paprike. Fagi su izolovani iz uzoraka zemljišta, vode i semena paprike poreklom iz različitih lokaliteta u Srbiji. Pored faga izolovanih u Srbiji, proverena je specifičnost 53 soja dobijenih iz kolekcije Univerziteta u Floridi i izdvojen set faga koji se mogu koristiti u diferencijaciji vrsta X. euvesicatoria, X. perforans, X. vesicatoria i X. gardneri.",

AB  - Usled poteškoća u razlikovanju vrsta roda Agrobacterium i nedostatka standardizovanog protokola izvršena je procena i odabir pogodnih metoda u cilju njihove diferencijacije na osnovu fizioloških, genetskih i patogenih odlika. Diferencirani su sojevi Agrobacterium tumefaciens, A. rhizogenes i A. vitis primenom standardnih bakterioloških i molekularnih metoda. Primenom diferencijalnih testova sojevi su ispoljili očekivane biohemijsko-fiziološke karakteristike. Izvedene su dve „duplex“ PCR metode sa 4 različita tipa prajmera. Kod proučavanih sojeva detektovano je prisustvo virD2 i virC gena patogenosti, koji se nalaze na plazmidnoj DNK bakterije. Prisustvo hromozomskog gena pehA, odgovornog za sintezu enzima poligalakturonaze, utvrđeno je kod soja A. vitis. Patogenost je proverena na kriškama mrkve i mladim biljkama paradajza i suncokreta. Sojevi A. tumefaciens i A. vitis bili su tumorogeni na svim test biljkama, dok je soj A. rhizogenes ispoljio patogenost jedino na kriškama mrkve. Na osnovu dobijenih rezultata, proučavani sojevi diferencirani su kao tumorogeni (Ti) Agrobacterium tumefaciens i A. vitis, i kao rizogeni (Ri) A. rhizogenes.

AB  - Bacterial strains were isolated from above- and underground parts of diseased calla plants originating from different localities in Serbia and one locality in Montenegro. They were characterized by studying their pathogenic, cultural, biochemical and physiological characteristics. All investigated strains caused soft rot of calla leaf stalks, potato slices and aloe leaves, and induced hypersensitive reaction on tobacco. Bacteriological properties of the strains indicated that symptoms on calla plants were caused by Gram-negative, nonfluorescent, oxidase negative, catalase positive and facultatively anaerobic bacterium belonging to the genus Pectobacterium. The investigated strains grew at 37ºC and in 5% NaCl, utilised lactose and trechalose, and produced neither indol nor lecitinase. These results, as well as the characteristic growth on Logan's differential medium indicated that soft rot of tuber and stem base of calla plants was caused by Pectobacterium carotovorum subsp. carotovorum. This is the first report of this pathogen affecting calla plants in Serbia.
AB  - Proučene su patogene, odgajivačke i biohemijsko-fiziološke odlike sojeva izolovanih iz nadzemnih i podzemnih delova obolelih biljaka kale gajene u različitim lokalitetima u Srbiji i jednom lokalitetu u Crnoj Gori. Svi proučavani sojevi ispoljili su izraženu pektolitičku aktivnost prouzrokujući vlažnu trulež lisnih drški kale, kriški krompira, liski aloje ili sanseverije, a prouzrokovali su i hipersenzitivnu reakciju duvana. Proučavanjem bakterioloških karakteristika utvrđeno je da promene na biljkama kale prouzrokuju Gram-negativni, nefluorescentni, oksidaza-negativni, katalaza-pozitivni i fakultativno-anaerobni sojevi bakterije, koja prema navedenim karakteristikama pripada rodu Pectobacterium. Proučavani sojevi se razvijaju pri 37ºC i u prisustvu 5% NaCl, razlažu laktozu i trehalozu, ne stvaraju indol i lecitinazu. Navedeni rezultati, kao i karakterističan razvoj na Loganovoj diferencijalnoj podlozi ukazuju da je vlažnu trulež korena i prizemnog dela biljaka kale prouzrokovala bakterija Pectobacterium carotovorum subsp. carotovorum.
