Spatial analysis to assess the relationship between human and bovine brucellosis in South Korea, 2005-2010.

The first case of human brucellosis in South Korea was reported in 2002, and cases of human infection continue to occur. Although an association between human and bovine brucellosis has been identified, the spatial relationship has not been studied in South Korea. Here, we analysed the spatial patterns of human and bovine brucellosis retrieved from the human and veterinary surveillance data, as well as the spatial correlation between human and bovine brucellosis and associated factors that contribute to its occurrence. The risk of human brucellosis was analysed using a Bayesian spatial model with potential risk factors. Our results show that, for both human and bovine brucellosis, hotspots were clustered in the southeast regions of Korea, whereas coldspots were clustered in the northwest regions of Korea. Our study suggests that the risk of human brucellosis increases in rural regions with the highest risk of bovine brucellosis. Collaborative strategies between human and veterinary health sectors (e.g, public health intervention and region-specific eradication programs for bovine brucellosis) would reduce the burden of brucellosis in South Korea.

Brucellosis in an adult female from Fate Bell Rock Shelter, Lower Pecos, Texas (4000-1300 BP).

OBJECTIVE: This project is a case study discussing the differential diagnosis of multiple osteolytic vertebral lesions typical of brucellosis from an adult female from Fate Bell Rock Shelter in the Lower Pecos, Texas (4000-1300 BP). MATERIALS: One middle to late adult female with exceptional preservation of the vertebrae. METHODS: All skeletal remains were observed with low power magnification and the vertebrae were examined in greater detail using computed tomography (CT). RESULTS: Pathological conditions involving multiple osteolytic vertebral lesions such as tuberculosis, echinococcosis, and neoplastic conditions were reviewed but brucellosis is the most likely diagnosis based on the pattern and distribution of characteristic lesions. CONCLUSIONS: Aside from this study, only one other case of brucellosis has been recognized in prehistoric North American hunter-gatherer skeletal remains. SIGNIFICANCE: This individual represents the first case of brucellosis in a hunter-gatherer from prehistoric North America diagnosed using both macroscopic skeletal analysis and computed tomography (CT). LIMITATIONS: Poor preservation of vertebrae make cross comparison of remains and differential diagnosis difficult. SUGGESTIONS FOR FURTHER RESEARCH: Further review and paleopathological research is needed regarding Coxiella burnetti (Q-fever) infection as a possible contributing factor to osteolytic lesions.

[Technical assistance in crisis times: Brucelosis in the country programs for Spain of the world health organization (1951-1972)]. / Ayuda técnica en tiempos de crisis: la brucelosis en los programas país para España de la organización mundial de la salud (1951-1972).

OBJECTIVE: Brucellosis was one of the most important health problems in post-Civil War Spain and in subsequent years. The objective of the study was to reconstruct the first programs that the WHO set up in this country, to address this problem, between 1951 and 1972 and their main outcomes. METHODS: On the basis of primary sources of diverse origin, especially unpublished reports on Spain from foreign experts, from the WHO Historical Archive, the contents related to the disease were analyzed, contextualizing them within the framework of both the history of Spanish Public Health during the period studied and the international public health strategies for the prevention and control of brucellosis between 1951 and 1972. RESULTS: Spain 0001 (E1), Spain 0012 (E12) programs were located. The first of them (E1), dedicated to the problem of endemoepidemic diseases (brucellosis, rabies and Q fever), developed between 1952 and 1956, offered assistance in the work of control of these diseases carried out by public health laboratories. The second was preceded by visits of experts between 1956-1958 and formally started in 1969 and ended in 1972. This program was specifically devoted to the fight against brucellosis and included the start-up of laboratory and epidemiological work, the training of specialists, vaccination experiences in goats and sheep and the initiation of studies on immunizations in humans. CONCLUSIONS: The presence of consultants and experts from the WHO, from the highest scientific authority in the field of brucellosis such as Sandford Elberg or Martin Kaplan, was decisive in, at least, two aspects: first, to have an external view that would allow to know the reality of the Spanish health situation in the matter of the control of this zoonosis and, secondly, to start up and develop laboratory techniques and training of specialists with the aim of creating, at least, a center of reference for the preparation of vaccines, which the experts placed, ideally, in the National School of Health in Madrid.

El objetivo del estudio fue reconstruir los primeros programas que la OMS puso en marcha en este país, para abordar dicho problema, entre 1951 y 1972 y sus consecuencias. METODOS: Sobre la base de fuentes primarias de diversa procedencia, en especial, informes inéditos sobre España de expertos extranjeros, procedentes del Archivo Histórico de la OMS, se analizaron los contenidos relativos a la enfermedad, contextualizándolos tanto en el marco de la historia de la salud pública española del periodo objeto de estudio como en el de las estrategias a nivel internacional desarrolladas en este campo. RESULTADOS: Se localizaron los programas España 0001 (E1) y España 0012 (E12). El primero de ellos (E1), dedicado al problema de las enfermedades endemo-epidémicas (brucelosis, rabia y fiebre Q), desarrollado entre 1952 y 1956, ofreció asistencia en las labores de control de estas enfermedades llevadas a cabo por los laboratorios de salud pública. El segundo, precedido de visitas de expertos, entre 1956-1958, se inició formalmente en 1969 y finalizó en 1972, se consagró específicamente a la lucha contra la brucelosis e incluyó la puesta en marcha de trabajos de laboratorio y epidemiológicos, formación de especialistas, experiencias vacunales en ganado caprino y ovino e inicios de estudios sobre inmunizaciones en humanos. CONCLUSIONES: La presencia de consultores y expertos de la OMS de la máxima autoridad científica en el campo de la brucelosis, como Sandford Elberg o Martin Kaplan, fue decisiva en dos aspectos al menos, en primer lugar, para poder disponer de una mirada externa que permitiera conocer la realidad de la situación sanitaria española en el tema del control de dicha zoonosis y, en segundo lugar, para la puesta en marcha y el desarrollo de técnicas de laboratorio y de formación de especialistas con el objetivo de crear, al menos, un centro de referencia para la confección de vacunas, que los expertos situaban, de forma idónea, en la Escuela Nacional de Sanidad en Madrid.

Outbreak of human brucellosis in Southern Brazil and historical review of data from 2009 to 2018.

BACKGROUND: Human brucellosis (HB) is a bacterial zoonosis that is more frequent in low income and middle-income countries; it is sometimes associated with outbreaks. The aim of this study was to describe the largest outbreak of HB in Brazil. METHODS: A retrospective cohort study of patients suspected of having contracted HB in the state of Paraná, Southern Brazil from January 2009 to January 2017. Following an outbreak of 51 cases of HB in a slaughterhouse at Paiçandu in 2014, HB was defined as an obligatory reportable disease in the State. Diagnostic tests for HB included serum agglutination, ELISA (IgG or IgM) and polymerase chain reaction (PCR). Clinical, laboratorial and epidemiological data were analyzed. A P value of 0.05 was considered statistically significant. RESULTS: Out of a total of 3,941 patients, 754 presented with a positive test result for HB. After 2014, there was a significant increase in the number of cases, exceeding 100 cases per trimester. In the beginning of 2015, the workgroup of HB started several actions for prevention and treatment, and the number of cases progressively diminished to fewer than 20 cases per trimester. Of 191 reported cases, an occupational risk was found in 84.7%; most cases occurred in farmers (60.0%), veterinarians (17.6%) and slaughterhouse workers (14.7%). Manipulation of animals and unpasteurized milk consumption were associated with positive Brucella IgM ELISA with an odds ratio (OR) of 1.42 (1.09-1.84) and 1.48 (1.01-2.15), respectively. CONCLUSIONS: HB outbreaks can occur in low to middle-income countries and are associated with slaughterhouse work, handling of unpasteurized milk and animal manipulation. Intensive programs for control of HB are important to reduce the number of cases.

Proteomic Analyses on an Ancient Egyptian Cheese and Biomolecular Evidence of Brucellosis.

The material analyzed in this study is probably the most ancient archeological solid residue of cheese ever found to date. The sample was collected during the Saqqara Cairo University excavations in the tomb of Ptahmes dated to XIX dynasty ( El-Aguizy, O. Bulletin de l'Institut Française d'Archéologie Orientale (BIFAO) 2010 , 110 , 13 - 34 (ref (1) ); Staring, N. Bulletin de Institut Français d'Archéologie Orientale (BIFAO) 2015 , 114 , 455 - 518 (ref (2) )). Our biomolecular proteomic characterization of this archeological sample shows that the constituting material was a dairy product obtained by mixing sheep/goat and cow milk. The interactions for thousands of years with the strong alkaline environment of the incorporating soil rich in sodium carbonate and the desertic conditions did not prevent the identification of specific peptide markers which showed high stability under these stressing conditions. Moreover, the presence of Brucella melitensis has been attested by specific peptide providing a reasonable direct biomolecular evidence of the presence of this infection in the Ramesside period for which only indirect paleopathological evidence has been so far provided ( Pappas, G.; Papadimitriou P. Int. J. Antimicrob. Agents 2007 , 30 , 29 - 31 (ref (3) ); Bourke, J. B. Medical History 1971 , 15 ( 4 ), 363 - 375 (ref (4) )). Finally, it is worth noting that, although proteomic approaches are successfully and regularly used to characterize modern biological samples ( D'Ambrosio, C.; Arena, S.; Salzano, A. M.; Renzone, G.; Ledda, L.; and Scaloni, A. Proteomics 2008 8 , 3657 - 3666 (ref (5) ), their application in ancient materials is still at an early stage of progress, only few results being reported about ancient food samples ( Yang, Y.; Shevchenko, A.; Knaust, A.; Abuduresule, I.; Li, W.; Hu, X.; Wang, C.; Shevchenko, A. J. Archaeol. Sci. 2014 , 45 , 178 - 186 (ref (6) ). In the absence of previous relevant evidence of cheese production and/or use, this study, undoubtedly has a clear added value in different fields of knowledge ranging from archaeometry, anthropology, archeology, medicine history to the forensic sciences.

Trend Analysis and Affecting Components of Human Brucellosis Incidence During 2006 to 2016.

INTRODUCTION: Brucellosis is communicable between humans and animals. In spite of having an active health care system. Iran is considered as an endemic area and it stands in the fourth place in world ranking. One of the common methods for identifying the disease incidence is a regression analysis. Therefore, the aim of the study was to investigate the trend of brucellosis incidence during 2006 to 2016 and the components affecting such disease. MATERIALS AND METHODS: This was a trend study which was conducted on the total of 144 brucellosis cases were recorded in the registration software in CDC of Iranian, Ministry of Health. We analyzed the changes in brucellosis incidence during 2006 to 2016 in Juybar province by the join point regression. Moreover, comparing the changes of incidence in one year intervals was also taken into account. RESULTS: The average age of patients was 18±29 years. About 60% of the patients were men, and 85.4% had used non-pasteurized dairy and meat products. The contact with animals had a significant difference between the two genders (P= 0.006). During 2006 to 2016, brucellosis incidence had a decreased trend about 15%. This trend had a breakpoint in a way that during 2006 to 2008, 66.2% decrease and during 2008 to 2016, 7% increase was observed that none of these annual percentage changes (APC) were statistically significant at p= 0.05. Also, APC of brucellosis incidence in groups below 20 and between 20 to 50 years old had a decrease in a way that in groups under 20, it had 26.7% decrease and it was statistically significant. CONCLUSION: It is necessary to provide appropriate education training, information on the Human Brucellosis for the young and individuals with high risk professions. Moreover, some health behaviors such as not using non-pasteurized dairy, animals' vaccinations, and awareness of the disease symptoms are needed.

Changing Epidemiology of Human Brucellosis, China, 1955-2014.

Brucellosis, a zoonotic disease, was made statutorily notifiable in China in 1955. We analyzed the incidence and spatial-temporal distribution of human brucellosis during 1955-2014 in China using notifiable surveillance data: aggregated data for 1955-2003 and individual case data for 2004-2014. A total of 513,034 brucellosis cases were recorded, of which 99.3% were reported in northern China during 1955-2014, and 69.1% (258, 462/374, 141) occurred during February-July in 1990-2014. Incidence remained high during 1955-1978 (interquartile range 0.42-1.0 cases/100,000 residents), then decreased dramatically in 1979-1994. However, brucellosis has reemerged since 1995 (interquartile range 0.11-0.23 in 1995-2003 and 1.48-2.89 in 2004-2014); the historical high occurred in 2014, and the affected area expanded from northern pastureland provinces to the adjacent grassland and agricultural areas, then to southern coastal and southwestern areas. Control strategies in China should be adjusted to account for these changes by adopting a One Health approach.

Human Brucellosis in Febrile Patients Seeking Treatment at Remote Hospitals, Northeastern Kenya, 2014-2015.

During 2014-2015, patients in northeastern Kenya were assessed for brucellosis and characteristics that might help clinicians identify brucellosis. Among 146 confirmed brucellosis patients, 29 (20%) had negative serologic tests. No clinical feature was a good indicator of infection, which was associated with animal contact and drinking raw milk.

[Not Available]. / Les recherches d'Étienne Burnet (1920-1928) sur la brucellose.

Mediterranean fever or brucellosis was an endemic disease at the beginning of the 20th century in the Mediterranean area. Étienne Burnet, a pastorian researcher, studied this zoonosis in the Pasteur Institute of Tunis between 1920 and 1928 and enhanced our knowledge with various experiences on the genius Brucella, particularly melitensis variety. He developed the so-called Burnet's test or melitine IDR diagnose test. The thermo-agglutination of paramelitensis group, now known as the S forms colonies, led him question the variability of this non-specific character. He showed that thermo-agglutination is associated with specific antigenic properties and is common with other bacteria's species and could be acquired cross over colonies culture... The authors attempt to reconstitute the context of these experiences and to show the actuality of evolutionary Burnet's conception of living micro-organisms.

Historical perspective of brucellosis: a microbiological and epidemiological overview.

The historical process of brucellosis extends back to humankind's first contact with animals. Although brucellosis is a sporadic disease observed in animals in certain regions of the world, it is an important disease in humans that can affect many organs and systems due to the consumption of contaminated milk or milk products. Studies have shown that the presence of Brucella dates back to 60 million years ago. In 450 BC, Hippocrates described a disease similar to brucellosis. Since Hippocrates' time, brucellosis has been characterized by fever. Our aim is to investigate selfless work undertaken by scientists on the epidemiology, diagnosis and clinical findings of brucellosis until today, and to gain a historical perspective about the disease that is as old as human history, still has importance today, causes economic losses in treated animals and harms human health.

La brucelosis humana, ayer y hoy / No disponible

La brucelosis es una zoonosis distribuida por la mayor parte del mundo. En España tuvo una incidencia importante, estimándose en 5.000 los casos anuales al final de la primera mitad del s.XX, llegando a 8.692 casos en 1984, lo que hizo que se pusieran en marcha programas de control, que contribuyeron a reducir el número de casos, hasta los 103 declarados en 2013. La enfermedad, ha tenido una importante repercusión sanitaria y socioeconómica por la afectación del hombre y de los animales. Su pronóstico en general, ha sido bueno, salvo complicaciones. El tratamiento en las primeras décadas del s. XX, era básicamente sintomático, al no disponerse de ningún remedio efectivo. Posteriormente, los arsenicales, las sales de oro y la vacuna intravenosa, entre otros, tuvieron una aportación destacable, hasta la llegada de los antibióticos, que supuso un cambio radical en la evolución de la enfermedad (AU)

Brucellosis is a zoonosis spread throughout the world. It had a rather important incidence in Spain. An estímate of of 5000 cases per year took place in Spain during the first half of the 20th. century, reaching a peak of 8,692 in 1984. This fact promoted the establishment of control mechanisms that contributed to gradually diminish the number of cases to 103 in 2013. Brucellosis has had a considerable importance both in the health and socioeconomic fields due to vulnerability in humans and animals. The disease had a good prognosis, putting aside possible complications. Treatment, in the first decades of the 20th. Century was basically symptomatic, given the lack of effective remedies. Later, arsenic components, gold salts and the intravenous vaccine, among others, had a relevant importance in treatment until the appearance of antibiotics. These had a radical influence in the natural evolution of the disease (AU)

Narrative overview of animal and human brucellosis in Morocco: intensification of livestock production as a driver for emergence?

Brucellosis is one of the most widespread zoonoses in the world caused by several species of the genus Brucella. The disease, eradicated in many developed countries, is a re-emerging neglected zoonosis endemic in several zones especially in the Mediterranean region, impacting on human health and livestock production. A One Health approach could address brucellosis control in Morocco but scarcity of reliable epidemiological data, as well as underreporting, hinders the implementation of sustainable control strategies. Surveillance and control policies implemented by the Moroccan government in domestic animals (cattle and small ruminants) in the last few decades are assessed for disease impact. This study considers the origins of animal brucellosis in Morocco and the potential for emergence of brucellosis during a shift from extensive to intensive livestock production.

Annual trends of human brucellosis in pastoralist communities of south-western Uganda: a retrospective ten-year study.

BACKGROUND: Human brucellosis is prevalent in both rural and urban Uganda, yet most cases of the disease in humans go unnoticed and untreated because of inaccurate diagnosis, which is often due to the disease not manifesting in any symptoms. This study was undertaken to describe trends in laboratory-confirmed human brucellosis cases at three health facilities in pastoralist communities in South-western, Uganda. METHODS: Data were collected retrospectively to describe trends of brucellosis over a 10-year period (2003-2012), and supplemented with a prospective study, which was conducted from January to December 2013. Two public health facilities and a private clinic that have diagnostic laboratories were selected for these studies. Annual prevalence was calculated and linearly plotted to observe trends of the disease at the health facilities. A modified Poisson regression model was used to estimate the risk ratio (RR) and 95 % confidence intervals (CIs) to determine the association between brucellosis and independent variables using the robust error variance. RESULTS: A total of 9,177 persons with suspected brucellosis were identified in the retrospective study, of which 1,318 (14.4 %) were confirmed cases. Brucellosis cases peaked during the months of April and June, as observed in nearly all of the years of the study, while the most noticeable annual increase (11-23 %) was observed from 2010 to 2012. In the prospective study, there were 610 suspected patients at two public health facilities. Of these, 194 (31.8 %) were positive for brucellosis. Respondents aged 45-60 years (RR = 0.50; CI: 0.29-0.84) and those that tested positive for typhoid (RR = 0.68; CI: 0.52-0.89) were less likely to have brucellosis. CONCLUSIONS: With the noticeable increase in prevalence from 2010 to 2012, diagnosis of both brucellosis and typhoid is important for early detection, and for raising public awareness on methods for preventing brucellosis in this setting.

Florence Nightingale (1820-1910) and Sir John Forbes (1787-1861): neighbours in Old Burlington Street, Westminster.

The year 2010 marks the centenary of the birth of Florence Nightingale and will, no doubt, be universally remembered. Her life and nursing career have recently been fully described by Bostridge. It is less well known that her neighbour from November 1856 was the distinguished Scottish physician Sir John Forbes MD Edin FRCP Lond FRS DCL Oxon. Although they never met, they exchanged copies of each other's books and shared a mutual respect.

Lessons from the history of brucellosis.

The disease we now know as brucellosis was first discovered in the 1850s in Malta. It came to the attention of British medical officers serving on the island after the Crimean War. It was easy to eliminate the disease in British servicemen, but very difficult to reach Maltese citizens. Over the decades, more and more Maltese were infected asthe control measures introduced were half-hearted and were often not even enforced. The work of Dr Themistocles Zammit showed that infected goats transmitted brucellosis and that banning use of their milk would be effective. Pasteurisation was not introduced onto the island until the 1930s, when the production of cheap, small sterile containers became possible. Transmission was also possible through sexual contact and by inhalation when people were crowded in hot airless conditions. Success in controlling the disease requires sensible, strict control of animals and the elimination of infected ones, but will fail without an educated public willing to help. In Malta, failure to control rogue flocks and small flocks kept for family use led to an epidemic caused by the sale of cheeselets (small cheeses). In 2005, nearly a century after Zammit's discovery, Malta was finally free of brucellosis.

[Paleopathology of Herculaneum's population (79 D.C.)]. / Aspetti di paleopatologia della popolazione di Ercolano (79 D.C.).

In 1982, some occasional excavations in the area corresponding to the ancient beach of Ercolano brought to light the rests of around 250 individuals, victims of the eruption of the Vesuvius. This exceptional recovery constitutes an essential patrimony for the reconstruction of the paleobiology and the paleopathology of the human populations in Roman epoch, in relationship not only to the style of life but also to the social and economic status. Notwithstanding the bone alterations due to the exposition to high temperature, the human remains present traces of illness. Among these we find rheumatic pathologies and arthrosis of the vertebral column. The high frequency of occupational markers (enthesopaties and sindesmopaties) suggests that the most part of the population (juveniles included) exercised hand work. Among the infectious pathologies we report cases of the tuberculosis and brucellosis.
