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...

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...

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...

Sporadic human cutaneous anthrax outbreak in Shaanxi Province, China: report of two cases from 2018 BJID
Liu,Yuanyuan; Li,Yongqin; Wang,Qiaoxia; Fu,Jianjun; Ji,Fanpu.
ABSTRACT China’s compulsory annual livestock anthrax vaccination policy has remarkably reduced but not completely eradicated human anthrax infections. Herein we describe a sporadic human cutaneous anthrax outbreak involving two cases in 2018 in Shaanxi Province, both involving herdsman who dealt with unvaccinated and potentially sick cattle. Both patients showed Bacillus anthracis-positive blister smear and blood culture. Treatment with penicillin was followed by uneventful recovery for both. The prompt performance of the prophylactic measures successfully interrupted the further transmission of this sporadic human cutaneous anthrax outbreak.

Vaccination coverage in a cohort of HIV-infected patients receiving care at an AIDS outpatient clinic in Espírito Santo, Brazil BJID
Pinto Neto,Lauro Ferreira da Silva; Vieira,Julia Vescovi; Ronchi,Nathália Rossoni.
Abstract This cross-sectional study assessed the immunization status of human immune deficiency virus (HIV)-infected patients receiving care at an outpatient clinic in Brazil. The sociodemographic characteristics, CD4 count and HIV viral load of 281 out of 612 adult outpatients were analyzed. A total of 331 patients were excluded because of no availability of vaccination cards. Chi-square or Fisher's exact test were used. Immunization coverage was higher for diphtheria/tetanus (59.79%) and hepatitis B (56.7%), and lowest for hepatitis A (6.8%) and for meningococcal group C (6%). Only 11.74% of the patients had received the influenza virus vaccine yearly since their HIV-infection diagnosis. No vaccination against influenza (p < 0.034) or hepatitis B (p...

Hepatitis B in healthcare workers: prevalence, vaccination and relation to occupational factors BJID
Ciorlia,Luiz A.S.; Zanetta,Dirce M.T..
The prevalence of hepatitis B virus (HBV) in healthcare workers (HCW) in Brazilian university hospitals is high. However, vaccination of these workers and relations with occupational factors are not well documented. A prospective study was made of 1,433 HCW and 872 administrative employees of the Hospital de Base (HB), São José do Rio Preto, SP, Brazil, and 2,583 blood donor candidates from the Hospital Blood Bank. HCW were observed from January 1994 to December 1999. Data were obtained from exams made when a worker entered hospital service, periodically and after work-related injuries. Serological reactions were analyzed in HCW who received HBV vaccine. Occupational and non-occupational information was obtained through a questionnaire. The prevalence of...

Risk factors for poor immune response to influenza vaccination in elderly people BJID
Bellei,N.C.J.; Carraro,E.; Castelo,A.; Granato,C.F.H..
Influenza vaccination of elderly people is efficacious and cost effective for the prevention of influenza and its complications. Some studies have pointed out low immunogenicity in this group. Health status has been poorly investigated as a risk factor that may influence the immune response to influenza vaccine. We established an immunization response study of a highly-matched elderly population in a nursing home. One-hundred-twenty subjects of Ashkenazian origin had their vaccine-induced antibody response assessed. Good response was obtained in 30.8% (37/120), and 31.7% (38/120) did not react. A lack of good response was found to be associated with dementia (P=0.016) in a multivariate analysis. In addition to dementia, malnutrition was frequently observed...

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...

Rabies infection and specific effect of vaccination in mice selected for high and low immunobiological parameters BJMBR
Queiroz-da-Silva,L.H.; De-Franco,M.; Sant'Anna,O.A.
Innate and acquired resistance to rabies infection was investigated in mice genetically selected for high (H) or low (L) antibody responsiveness from selections I, III and IV and in mice selected for maximal (AIRmax) or minimal (AIRmin) acute inflammatory reaction. These mouse lines were infected intramuscularly with different virus dilutions and the LD50 was determined. The HIII and HIV mouse lines were more susceptible than the LIII and LIV lines and the HI line showed a discrete but higher resistance than the LI line. Analysis of the interline (H x L) F1 hybrids from selections III and IV indicated different dominance effects on the "resistant" and" susceptible" phenotypes when the route of vaccination was changed. No differences were observed between...

HPV vaccines: a controversial issue? BJMBR
Nicol,A.F.; Andrade,C.V.; Russomano,F.B.; Rodrigues,L.L.S.; Oliveira,N.S.; Provance Jr,D.W..
Controversy still exists over whether the benefits of the available HPV vaccines outweigh the risks and this has suppressed uptake of the HPV vaccines in comparison to other vaccines. Concerns about HPV vaccine safety have led some physicians, healthcare officials and parents to withhold the recommended vaccination from the target population. The most common reason for not administering the prophylactic HPV vaccines are concerns over adverse effects. The aim of this review is the assessment of peer-reviewed scientific data related to measurable outcomes from the use of HPV vaccines throughout the world with focused attention on the potential adverse effects. We found that the majority of studies continue to suggest a positive risk-benefit from vaccination...

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...

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...

Reimmunization after bone marrow transplantation: current recommendations and perspectives BJMBR
Machado,C.M..
Autologous and allogeneic bone marrow transplantation (BMT) recipients lose immune memory of exposure to infectious agents and vaccines accumulated through a lifetime and therefore need to be revaccinated. Diphtheria toxoid, tetanus toxoid, pertussis vaccine (children <7 years old), Haemophilus influenzae type b conjugate, 23-valent pneumococcal polysaccharide, inactivated influenza vaccine, inactivated polio vaccine and live-attenuated measles-mumps-rubella vaccine are the currently recommended vaccines to be included in a vaccination program after BMT. For most of them, the best time to vaccinate, the number of vaccine doses and/or the duration of immunity after vaccination have not been established. Vaccination protocols vary greatly among BMT...

Genetic variability of hepatitis A virus isolates in Rio de Janeiro: implications for the vaccination of school children BJMBR
Villar,L.M.; Lampe,E.; Meyer,A.; Gaspar,A.M.C..
The epidemiology of hepatitis A virus (HAV) infection is shifting from high to intermediate endemicity in Brazil, resulting in increased numbers of susceptible individuals and a greater potential for the emergence of outbreaks. Universal vaccination against HAV has been recommended for children, but updated sero-epidemiological data are necessary to analyze the level of natural immunity and to identify candidates for preventive measures. In addition, more molecular studies are necessary to characterize the genotypes involved in HAV infections and outbreaks. Sera from 299 school children (5-15 years old) and 25 school staff members, collected during an outbreak of HAV at a rural public school in June 2000, were tested for IgM and total anti-HAV antibodies...

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...

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...
