Spatial analysis of leptospirosis and toxoplasmosis seroprevalence in the canine population in an area of socioeconomic and environmental vulnerability
ABSTRACT Leptospirosis and toxoplasmosis are zoonoses of occupational character that are spread worldwide, mainly in tropical and socioeconomically vulnerable areas. Both diseases have vertebrate hosts, which spread the infectious agent to the environment and are potentially infectious to humans and can progress to fatal cases. The present study reinforces the importance of One Health for the control and prophylaxis of leptospirosis and toxoplasmosis using sentinel animals in areas of socioeconomic vulnerability based on a serological study. A total of 336 blood samples were obtained from the canine population of the urban district, which has high rates of poverty and sanitation. The results were analyzed based on seroreactivity animals and georeferencing by kernel spatial mapping. A total of 43.3% (52/120) of the animals were seroreagents for anti-Leptospira spp., with a predominance of Canicola (35/52 = 67.3%) and Pyrogenes (5/52 = 9.6%), while 52.97% (178/336) of the dogs were seroreactive for anti-Toxoplasma gondii. The presence of seroreagent dogs for both zoonosis alert to the inadequate hygienic-sanitary conditions of the studied region, and highlight the importance of a survey of the social, economic and environmental structure to identify factors related to the links in the epidemiological chain of pathogen transmission and necessary corrective actions

Understanding and using somatic cell counts to improve milk quality
peer-reviewedThe production of high quality milk is a requirement to sustain a profitable dairy
industry and somatic cell count (SCC) values are routinely used to identify subclinical
mastitis and define quality standards. The objective of this paper is to review the use
of SCC as a diagnostic tool for subclinical mastitis in order to improve milk quality on
dairy farms. Mastitis is detected based on inflammation subsequent to intramammary
infection (IMI) by pathogenic organisms. Individual cow SCC values are used to detect
the inflammation that results from IMI and are necessary to define the prevalence and
incidence of subclinical IMI. A threshold of <200,000 cells/mL is considered to be of
the most practical value used to define a mammary quarter as healthy. The development
of IMI is the most significant factor that influences milk SCC and assessment
of monthly values to determine newly and chronically increased SCC can be highly
diagnostic for resolving problems with increased bulk tank SCC. Methods to reduce the development of new IMI are well known and adoption of best management practices for
milking and herd management have consistently been shown to result in reductions in bulk tank SCC. Implementation of mastitis control programmes can be improved by focusing on three practical recommendations: 1) Farmers should work with their advisors to develop an annual udder health plan that includes clear goals for milk quality. 2) The annual udder health plan should emphasise prevention of new IMI. 3) Farmers must identify and manage chronically infected cows. Proactive management of IMI can be extremely effective in helping farmers produce milk that meets industry standards for milk quality
Associação da ocorrência do ectima contagioso (ORF vÃrus) em ovinos com os cuidadores desses animais
RESUMO A enfermidade ectima contagioso está difundida em todo o estado de São Paulo. Foram amostrados 42 (8,64%) cuidadores de animais e 444 (91,36%) ovinos (n=486). A prevalência de reagentes para vÃrus-neutralização foi de 67% (IC95%=62-71%) nos ovinos, e em seus cuidadores de 76% (IC95%=63-89%), sendo P=0,22, ou seja, não houve diferença estatÃstica significativa entre as espécies. A distribuição dos tÃtulos teve diferença estatÃstica significativa entre as espécies, com P=0,0048. As variações de titulação foram de 0,6 a 2,1 tanto nos ovinos quanto nos seus cuidadores. Dentre os 42 cuidadores de ovinos participantes do estudo, 32 apresentaram tÃtulos de anticorpos expressos por log10 acima de 0,6
