An outbreak of acute bovine mastitis caused by Klebsiella pneumoniae in a dairy herd Arq. Bras. Med. Vet. Zootec.
Silva,N.; Costa,G.M..
An outbreak of coliform mastitis is described in a dairy herd from the State of Rio de Janeiro, Brazil. During a four-month period 14 fatal cases of Klebsiella pneumoniae-related mastitis were observed in a herd of 104 lactating cows. The symptoms included peracute enterotoxemia in which the cows died 6 to 12 h after the detection of mastitis by CMT. Staphylococcus aureus and Streptococcus agalactiae Streptococcus agalactiae were also isolated although could not be associated with cases of acute fatal mastitis. Milking practices were also evaluated. The milking machine was being used correctly and adequate precautions for hygiene and pre-milking and post-milking teat dipping were used. The organism was sensitive to gentamicin. Therapy for acute toxic...

Antibody response in silver catfish (Rhamdia quelen) immunized with a model antigen associated with different adjuvants BJMBR
Pavan,T.R.; Di Domenico,J.; Kirsten,K.S.; Nied,C.O.; Frandoloso,R.; Kreutz,L.C..
Adjuvants are essential to boost the immune response to inoculated antigen and play a central role in vaccine development. In this study, we investigated the efficacy of several adjuvants in the production of anti-bovine serum albumin (BSA) antibodies in silver catfish. Two hundred and seventy juvenile silver catfish (60–80 g) of both sexes were intraperitoneally vaccinated with BSA (200 µg/fish) alone or mixed to the following adjuvants: Freund’s complete adjuvant (FCA), Freund’s incomplete adjuvant (FIA), aluminum hydroxide (AlOH), Montanide, four types of cytosine-phosphate-guanine (CpG) oligodeoxynucleotides (ODNs) and three concentrations of β-glucan, and the immune enhancing property was evaluated by measuring anti-BSA antibodies in blood samples at...

Avian cytokines in health and disease Rev. Bras. Ciênc. Avic.
Wigley,P; Kaiser,P.
Cytokines are proteins secreted by cells that play an important role in the activation and regulation of other cells and tissues during inflammation and immune responses. Although well described in several mammalian species, the role of cytokines and other related proteins is poorly understood in avian species. Recent advances in avian genetics and immunology have begun to allow the exploration of cytokines in health and disease. Cytokines may be classified in a number of ways, but may be conveniently arranged into four broad groups on the basis of their function. Proinflammatory cytokines such as interleukin-6 and interleukin-1beta play a role in mediating inflammation during disease or injury. Th1 cytokines, including interleukin-12 and interferon-gamma,...

Avian Influenza outbreaks and poultry production mitigation strategies in the U.S. AgEcon
Mu, Jianhong H.; McCarl, Bruce A..
In this paper, two AI mitigation strategies are examined, quarantine and vaccination. Meanwhile, associated welfare changes are evaluated by using FASOM. Results found that changes of total national welfare of U.S are insignificant with or without vaccination. Once comes to livestock producers, impacts become significant although magnitudes are small. For example, under 20% demand shocks, vaccination strategy dominates no vaccination at the production, market and national level. However, vaccination has no advantage when there is no demand shifts.

BCG lymphadenopathy detected in a BCG-vaccinated infant BJMBR
Barouni,A.S.; Augusto,C.; Queiroz,M.V.N.P.; Lopes,M.T.P.; Zanini,M.S.; Salas,C.E..
Large-scale vaccination with BCG, the live attenuated strain of Mycobacterium bovis, is being adopted around the world, although sporadic complications have occurred after the procedure. Lymphadenopathy is not uncommon especially in babies under one year (0.73% of vaccinated infants), but the swelling subsides within 2 months in most cases, with no medical or surgical treatment. Brazil adopted BCG vaccination program earlier in the seventies and by 1995 more than 96% of the infant population received this immunization. We report here the occurrence of lymphadenopathy in a two-year-old child vaccinated with the Brazilian BCG strain. The diagnosis was made using a lymph node biopsy and intestinal aspirates that yielded a positive mycobacterial culture. The...

Chronic obstructive pulmonary disease is underdiagnosed and undertreated in São Paulo (Brazil): results of the PLATINO study BJMBR
Nascimento,O.A.; Camelier,A.; Rosa,F.W.; Menezes,A.M.B.; Pérez-Padilla,R.; Jardim,J.R..
Chronic obstructive pulmonary disease (COPD) is a common disease in adults over 40 years of age and has a great social and economic impact. It remains little recognized and undertreated even in developed countries. However, there are no data about its diagnosis and treatment in Brazil. The objectives of the present study were to evaluate the proportion of COPD patients who had never been diagnosed and to determine if the COPD patients who had been identified were receiving appropriate treatment. The Latin American Project for the Investigation of Obstructive Lung Disease (PLATINO) was a randomized epidemiological study of adults over 40 years living in five metropolitan areas, including São Paulo. The studied sample was randomly selected from the...

A vacinação é a forma mais utilizada para prevenir a bronquite infecciosa causada pelo vírus da bronquite infecciosa das galinhas (IBV). Contudo, as vacinas convencionais são incapazes de diferenciar aves infectadas de vacinadas. No presente trabalho foi construído, caracterizado, e avaliado como candidato vacinal, um adenovírus recombinante expressando o gene N do IBV. O gene N foi clonado em um adenovírus humano tipo 5 defectivo e transfectado para as células HEK-293A para gerar rAd5_N. Após o vetor ser obtido como esperado e a confirmação da expressão da proteína N em HEK-293ª, foi realizada inoculação pela via oculo-nasal na dose de 107 TCID50/0,1mL para imunização de galinhas livres de patógenos específicos (SPF). A resposta imunológica do Ad5_N e a...

Cost-benefit analysis of sheep and goat brucellosis vaccination with Rev.1 in the north of Portugal from 2000 to 2005 Arq. Bras. Med. Vet. Zootec.
Coelho,A.M; Pinto,M.L; Coelho,A.C.
In the North of Portugal, a mass vaccination programme of small ruminants was conducted from 2001 to 2004. A study of cost-benefit was carried out for the 2000/2005 period to ascertain the economic benefits of this strategy. In order to estimate the cost of the zoonosis, the compensation costs paid to farmers for culled animals in the Brucellosis Eradication Campaign, data from vaccine Rev. 1 costs, and costs of people internment due to brucellosis were studied. An increase in the cost was observed from 2000 to 2001 (aproximately US$ 110,000), essentially due to compensation for culled animals, but also from vaccination and human internment costs. However, a progressive decrease was observed from 2001 to 2004 (from more than US$1,200,000 in 2001 to...

Cost-utility of quadrivalent versus trivalent influenza vaccine in Brazil – comparison of outcomes from different static model types BJID
Van Bellinghen,Laure-Anne; Marijam,Alen; de Araujo,Gabriela Tannus Branco; Gomez,Jorge; Van Vlaenderen,Ilse.
ABSTRACT Background: Influenza burden in Brazil is considerable with 4.2–6.4 million cases in 2008 and influenza-like-illness responsible for 16.9% of hospitalizations. Cost-effectiveness of influenza vaccination may be assessed by different types of models, with limitations due to data availability, assumptions, and modelling approach. Objective: To understand the impact of model complexity, the cost-utility of quadrivalent versus trivalent influenza vaccines in Brazil was estimated using three distinct models: a 1-year decision tree population model with three age groups (FLOU); a more detailed 1-year population model with five age groups (FLORA); and a more complex lifetime multi-cohort Markov model with nine age groups (FLORENCE). Methods: Analysis...

DAIRY HERD MANAGEMENT PRACTICES FOCUSING ON PREWEANED HEIFERS AgEcon
Ott, Stephen L..
The National Dairy Heifer Evaluation Project ( NDHEP ) was conducted by the National Animal Health Monitoring System (NAHMS ) from April 1991 through July 1992 with the assistance of 1,811 producers from 28 states. Producers included in the study each had herds of 30 or more milk cows, representing 78 percent of the milk cows in the U.S. The average total of cattle and calves on each operation was 169.4. The main breed on 94.9% of operations was Holstein. Slightly over 46 percent of operations stated reproductive problems as the cause of low milk production of cows culled from the herd. Newborn calves were separated from their mothers before nursing on 28.0 percent of operations and less than 12 hours after birth on 39.6 percent of operations. On 64.0...

Diagnostic efficiency of Brucella soluble antigens in immunodiffusion tests and ability to differentiate Brucella abortus strain 19 vaccinated cattle Braz. J. Vet. Res. Anim. Sci.
DAFFNER,José; ABALOS,Pedro; PINOCHET,Lautaro; SCORTTI,Mariela; URCELAY,Santiago.
Three soluble antigens were compared by radial immunodiffusion (RID) and agar gel immunodiffusion (AGID) tests: a native haptene (NH) from Brucella melitensis 16M, and a polysaccharide (PS) from B. abortus 1119-3, both obtained by non-hydrolytic methods, and the (O-Chain) polysaccharide extracted also from B. abortus 1119-3 but using an hydrolytic method. Three groups of bovine sera were tested: a) Naturally infected (n = 76); b) Non-infected (n = 130) and c) S-19 vaccinated (n = 61); the sensitivity (Se), the specificity (Sp) and the ability to differentiate vaccinated (ADV) were determined in each group a, b and c respectively. The highest Se in the RID test (84.3%) was achieved by NH; while the three antigens gave 100% Sp. The O-Chain showed 100% ADV in...

Diphtheria Antibodies and T lymphocyte Counts in Patients Infected with HIV-1 BJM
Speranza,Francisco A. B.; Ishii,Solange K.; Thuler,Luiz C. S.; Damasco,Paulo V.; Hirata Jr,Raphael; Mattos-Guaraldi,Ana L.; Milagres,Lucimar G..
We assessed the IgG levels anti-diphtheria (D-Ab) and T cell counts (CD4+ and CD8+) in HIV-1 infected subjects undergoing or not highly active antiretroviral therapy (HAART). Approximately 70% of all HIV-1 patients were unprotected against diphtheria. There were no differences in D-Ab according to CD4 counts. Untreated patients had higher D-Ab (geometric mean of 0.62 IU/ml) than HAART-patients (geometric mean of 0.39 IU/ml). The data indicated the necessity of keeping all HIV-1 patients up-to-date with their vaccination.

Abstract In swine and bovines, leptospirosis prevention and control is carried out via vaccination of susceptible animals using bacterins. However, the efficiency of leptospirosis vaccines has been questioned. This work aimed to investigate the potency of five leptospirosis vaccines sold commercially in Brazil, challenging the animals with one autochthonous strain of Leptospira, Canicola serovar, denoted LO4, isolated from swine. The standard protocol was followed, and renal carriers of Leptospira were identified among the surviving animals by culture and PCR. Of the five vaccines tested, only two proved effective. None of the surviving animals was positive by culture; however, one animal was positive by PCR. Three of the five vaccines sold commercially in...
