Implantação e ativação de rede wireless MAN na Batavo Cooperativa Agroindustrial
Freitas, Julio Cesar deEste trabalho apresenta uma descrição teórica da implementação de uma rede MAN, redundante na Batavo Cooperativa Agroindustrial, com o desafio de se pensar em uma tecnologia que viabilizasse o projeto levando em consideração o custo- benefício. Em diversas discussões entre o corpo técnico e os gerentes, e com vários orçamentos em mãos e até mesmo com outras tecnologias estudadas, chegou-se a conclusão que o mel...
Serological and molecular findings in diagnosis of leptospirosis serovar hardjo...
Hashimoto, Vanessa Yumi; Chideroli, Roberta Torres; Ribeiro, Juliane; Alfieri, Amauri Alcindo; Costa, Geraldo Marcio da; Pereira, Ulisses de PaduaThe cattle are considered hosts of the Hardjo serovar, causing economic damages due to the reproductive failures like abortions and infertility. The serovar Hardjo usually remains in the reproductive tract and also in the renal tubules where it is eliminated intermittently in the urine for months. Placental remnants, the aborted fetus and contaminated urine promote the permanence of this bacterium within the he...
Leptospirosis in stray dogs found in university campus: serological evaluation ...
Benitez, Aline; Rodrigues, Giovana Giuffrida; Gonçalves, Daniela Dib; Burke, Julieta Catarina; Alves, Lucimara Aparecida; Muller, Ernest EckehardtThe aim of this study was to demonstrate the Leptospirosis occurrence in stray dogs found in the campus of Universidade Estadual de Londrina – PR., from July to September 2007. The MAT (Microscopic Agglutination Test) was made as diagnostic serological test in 33 serum samples and the direct dark-field microscopy (DFM) in 10 urine samples. In the MAT, seven samples (21,21%) reacted and antibodies against the se...

Hashimoto, Vanessa Yumi; Gonçalves, Daniela Dib; Silva, Francielle Gibson da; Oliveira, Rosângela Claret de; Alves, Lucimara Aparecida; Reichmann, PeterA total of 320 horses were studied in this paper, both male and female, between two and 17 years of age, which were used for traction of wagons in the urban area of the municipality of Londrina (PR). These animals were kept, after their daily work, in abandoned areas or plots, in the outskirts of the urban area of the city. When these animals were attended by the veterinarians, between 1996 and 2005, none of th...

Gonçalves, Daniela Dib; Teles, Paulo Sérgi; Reis, Célia Rosimarie dos; Lopes, Fabiana Maria Ruiz; Freire, Roberta Lemos; Navarro, Italmar TeodoricoA leptospirose, brucelose e a toxoplasmose são zoonoses de ampla distribuição, sendo o homem participante acidental das suas cadeias epidemiológicas. O objetivo deste trabalho foi realizar levantamento soroepidemiológico e identificar variáveis ocupacionais e ambientais relacionadas a estas enfermidades em 150 trabalhadores de um frigorífico da região Norte do Paraná. Para o diagnóstico de leptospirose foi real...

Galhardo, Juliana Arena; Lopes, Melissa; Oliveira, Juçara Tinasi de; Tamanini, Ronaldo; Sanches, Samuel Fabre; Freitas, Julio Cesar deThe aim of this research was to evaluate the chilling tanks effectiveness on the reduction of microbial contamination of poultry carcasses from an abattoir, from March to September 2005. Poultry samples were taken in three times, in the beginning, middle and in the end of morning turn, in a total of 60 samples, 20 in each sampling time before the entrance in the chilling tank and other 60 samples, 20 in each sa...
Risk factors associated to leptospirosis in dogs in Londrina City - PR
Querino, Adriana Martins Vieira; Delbem, Ádina Cléia Botazzo; Oliveira, Rosângela Claret de; Silva, Francielle Gibson da; Müller, Ernst EckehardtLeptosporosis is a re-emergent zoonosis associated to close contact between man and dogs. It is important to determine whether the canine leptospirosis risk factors are similar to those of man or are variables exclusive to the species habitat and management. The objective of this study was to identify the individual and environmental variables most frequently associated with seropositive dogs attended in the Ve...
Aetiology of the intramammary infections and somatic cell counts in primiparae ...
Vianna, Luís Carlos; Müller, Ernst Eckehardt; Freitas, Julio Cesar de; Pretto-Giordano, Lucienne Garcia; Salvador, Rogério; Dias, Juliana AlvesTwo hundred primiparae cows from 12 milk properties in the west region of the São Paulo state and north region of Paraná state, were studied. About the animals studied, 86 (43%), showed infections in 140 (17,56%) quarters on the seventh day after parturition. On the first 150 days of lactation, 2372 milk samples were achived. About them, 504 (21,24%) were positive according to the bacteriological test. From the...
Study of Subclinical Mastitis in Dairy Herds of North Paraná, Brazil
Beloti, Vanerli; Müller, Ernst Eckehardt; Freitas, Julio Cesar de; Mettifogo, ElenaCalifornia Mastitis Test (CMT) was performed in five hundred and three Holstein cows from the north region of Paraná. One hundred and fifithy of these cows (29,82%) and 295 quarters in the CMT were positives. In 223 milk samples was observed bacterial growth (213 pure cultures and 10 associated cultures). The most commonly agents isolated in pure growth were, staphylococci (30,51%), whereas S. aureus (17,97%) a...

Alfieri, Amauri Alcindo; Alfieri, Alice Fernandes; Freitas, Julio Cesar de; Silva, Caio Abercio da; Freire, Roberta Lemos; Barros, Andrea RodriguesThis work describes the etiology of a postweaning diarrhoea focus in a intensive piggery. The results of identification procedures showed the simultaneous occurrence of Escherichia coli, rotavirus, picobirnavirus and Cryptosporidium parvum. In VERO cells culture, was detected the LT (termolabile toxin) production by three E. coli samples and VT (verotoxin) production by five samples.; No presente trabalho é des...
