ABSTRACT
Diseases arising from the imbalance between the triad environment, humans, and animals affect individuals' health, as well as the social, and economic well-being of the world's population. Across the globe, health education activities are being conducted to prevent and control zoonoses. To guide future educational interventions, we reviewed scientific articles published in the last five years to characterize and verify the tools: target audience, duration, effectiveness, and gaps and difficulties. Four databases were searched, and 16 articles were selected for the meta-analysis, with 81.3% of the studies being conducted in underdeveloped or developing countries. Of these, 56.3% involved children under 14 years of age, and 62.5% involved activities in elementary and middle schools. The researchers are the professionals who are the most engaged in the activities, and 56.3% of the studies are conducted by veterinarians. Several new teaching tools have been proposed, demonstrating remarkable effectiveness. For systematic reviews to provide a guide for the design of new educational activities, it is necessary to better describe teaching methodologies and evaluation tools, as well as to evaluate in the long term, not only the impact of knowledge on the population but also the incidence of zoonoses.
As doenças decorrentes do desequilíbrio entre a tríade ambiente, humanos e animais afetam a saúde dos indivíduos, bem como o bem-estar social e econômico da população mundial. Em todo o mundo, atividades de educação em saúde estão sendo realizadas para prevenir e controlar zoonoses. Para orientar futuras intervenções educativas, revisamos artigos científicos publicados nos últimos cinco anos para caracterizar e verificar as ferramentas: público-alvo, duração, efetividade, lacunas e dificuldades. Quatro bases de dados foram pesquisadas e 16 artigos foram selecionados para a meta-análise, com 81,3% dos estudos sendo conduzidos em países subdesenvolvidos ou em desenvolvimento. Destes, 56,3% envolviam menores de 14 anos e 62,5% envolviam atividades no ensino fundamental e médio. Os pesquisadores são os profissionais mais engajados nas atividades, sendo que 56,3% dos estudos são conduzidos por veterinários. Várias novas ferramentas de ensino foram propostas, demonstrando notável eficácia. Para que as revisões sistemáticas orientem o desenho de novas ações educativas, é necessário descrever melhor as metodologias de ensino e os instrumentos de avaliação, bem como avaliar a longo prazo não só o impacto do conhecimento na população, mas também a incidência de zoonoses.
Las enfermedades derivadas del desequilibrio entre el medio ambiente, los seres humanos y los animales afectan la salud de las personas, así como el bienestar social y económico de la población mundial. En todo el mundo se están realizando actividades de educación sanitaria para prevenir y controlar las zoonosis. Para orientar futuras intervenciones educativas, revisamos artículos científicos publicados en los últimos cinco años para caracterizar y verificar las herramientas: público objetivo, duración, efectividad, vacíos y dificultades. Se realizaron búsquedas en cuatro bases de datos y se seleccionaron 16 artículos para el metanálisis, y el 81,3 % de los estudios se realizaron en países subdesarrollados o en vías de desarrollo. De estos, el 56,3% involucraba a niños menores de 14 años y el 62,5% involucraba actividades en educación primaria y secundaria. Los investigadores son los profesionales más comprometidos con las actividades, siendo el 56,3% de los estudios realizados por veterinarios. Se han propuesto varias herramientas didácticas nuevas que han demostrado una eficacia notable.

Iran has raised concerns about the new outbreak of monkeypox (MV), it’s a serious issue for our 85 million population. Iran has identified its first case of monkeypox reported 16, Aug, woman aged 34, in the city of Ahvaz. The outbreak of the Monkeypox virus increasing daily in many areas, and causes deaths are reported. This article deals with the ongoing outbreak of monkeypox virus (zoonotic) that belongs to the genus orthopoxvirus, which was confirmed in May, 2022 and has similar symptoms as of smallpox but is less contagious and less severe illness than smallpox. The article also deals with its signs and symptoms, diagnosis, prevention, and treatment.
ABSTRACT
Scrub typhus is a common zoonotic disease with high case fatality rate. The clinical presentation of this disease may vary from acute febrile illness, thrombocytopenia, gastrointestinal manifestations, coagulopathy to neurological manifestations. The common neurological manifestations are meningitis and meningoencephalitis, whereas subdural hemorrhage, cerebrovascular accident, i.e., intracerebral hemorrhage, infarct, subarachnoid hemorrhage, etc. are among rare neurological presentations. Scrub typhus-induced neurological disease should be investigated to provide a timely and appropriate diagnosis and to reduce the mortality in complicated scrub typhus infection. Here we report a case of scrub typhus complicated with subdural hemorrhage admitted in our hospital.
ABSTRACT
Globally, vaccines against 47 infectious etiologic agents are approved by at least one regulatory authority as of December 2022. The numbers of viral diseases, infections caused by mycoplasma, bacterial and protozoal diseases, mycoses, diseases caused by parasitic worms, and other infectious diseases of unknown etiology run into thousands. Therefore, more vaccines are required to be developed to keep more populations disease free. Climate change and global increase in temperature may promote sea level rises and an increase in the intensity of rains, causing an upsurge in certain infectious diseases in regions of the human population and even causing movement of habitats. In societies where the expenditure on health as a percentage of gross domestic product is higher, people are more capacitated to tackle the treatment and spread of infectious diseases. As several of such conditions are zoonotic, well-planned strategies for controlling the spread would go a long way in the proper direction. Poverty and contagious diseases are infallibly linked. Major infectious diseases of poverty include tuberculosis, human immunodeficiency virus (HIV)/ acquired immuno deficiency syndrome (AIDS), malaria, measles, pneumonia, diarrheal diseases, and several neglected tropical diseases. The world is not yet unified in action to jointly work to contain the global problem of infectious diseases in every human habitat. There was a visible divide between and among the rich countries versus the developing countries regarding accessibility and deployment of vaccines against COVID-19 flu. To contain the spread of infectious diseases in the future, the whole world would have to work together, raising funds, strengthening epidemiological surveys, inventing effective vaccines, and vaccinating the eligible population, as also treating the infected with therapy in time, besides resorting to other preventive measures for overall human progress. The developmental efforts are to be pursued jointly and together to benefit all people, respecting the world as one.
ABSTRACT
@#We have previously isolated a novel avian Orthobunyavirus, Kedah Fatal Kidney Syndrome (KFKS) virus from a broiler farm in Kedah, Malaysia in 2020 with a severe kidney lesion in chickens. The virus was designated as KFKS2_CS virus. Sequence analysis of partial nucleocapsid (N) and nonstructural (NSs) sequence of this virus showed the highest sequence identity with previous KFKS1 from Malaysia (100%) and 97% with a zoonotic Umbre (UMB) virus, which was reported to cause encephalitis in immunocompromised humans in India. Phylogenetic analysis revealed that this virus was clustered together with previous KFKS1 virus from Malaysia, UMB and Cristoli viruses. This study aimed to assess the zoonotic potential of this KFKS2_CS virus in vitro by determining its ability to inhibit the production of interferon (IFN) in human glioblastoma multiforme (GBM) brain cells using reverse-transcriptase polymerase reaction (RT-PCR). This virus blocked the production of interferon-a in this human brain cells. In conclusion, this KFKS2_CS virus may have a zoonotic potential and become a public health concern in the future.
ABSTRACT
@#Abstract: Objective To report a case of suppurative knee arthritis caused by Pasteurella multocida and review relevant literature to improve the awareness of the clinical physicians regarding this bacterium and provide reference for clinical diagnosis and treatment. Methods A case of right knee suppurative arthritis caused by Pasteurella multocida was retrospectively reported and relevant literatures were reviewed in this article. Results The infected person was a 76-year-old female patient with a 5-year history of intermittent pain in his right knee and suffered from joint swelling, aggravation pain, and limited flexion and extension activities after intraarticular injection of sodium hyaluronate. After admission and completing all necessary tests, the patient was later confirmed to have been infected with Pasteurella multocida. The patient's right knee was promptly examined and cleared under arthroscopic surgery, synovium and meniscus were excised, a drainage tube was inserted, and continuous joint cavity irrigation was performed after the surgery, and then ceftriaxone was injected and amoxicillin/clavulanate potassium was taken orally for anti-infection and the patient's condition improved significantly after 26 days. Conclusions Pasteurella multocida infection cases are relatively rare, but the consequences in high-risk groups are relatively serious. Therefore, awareness of Pasteurella multocida and infection caused by it should be improved and high-risk groups should try to avoid contact with infectious sources as well as strengthen the management of pets so as to avoid infection.
ABSTRACT
Objective To construct an evaluation index system for the capability of comprehensive control of mountain-type zoonotic visceral leishmaniasis based on the One Health concept, so as to provide insights into the control and elimination of mountain-type zoonotic visceral leishmaniasis using the One Health approach. Methods A preliminary evaluation index system was constructed based on literature review, panel discussions and field surveys. Thirty-three experts were selected from 7 provincial disease control and prevention centers in Beijing Municipality, Hebei Province, Shanxi Province, Henan Province, Sichuan Province, Shaanxi Province and Gansu Province where mountain-type zoonotic visceral leishmaniasis was endemic, and two rounds of expert consultations were conducted to screen the indicators. The positive coefficient, degree of concentration, degree of coordination, and authority of the experts were calculated, and the normalized weights of each index were calculated with the analytic hierarchy process. Results The response rates of questionnaires during two rounds of expert consultation were both 100.00% (33/33), and the authority coefficients of the experts were 0.86 and 0.88, respectively. The coefficients of coordination among experts on the rationality, importance, and operability of the indicators were 0.392, 0.437, 0.258, and 0.364, 0.335, 0.263, respectively (all P values < 0.05). Following screening, the final evaluation index system included 3 primary indicators, 17 secondary indicators, and 50 tertiary indicators. The normalized weights of primary indicators “external environment”, “internal support” and “comprehensive control” were 16.98%, 38.73% and 44.29%, respectively. Among the secondary indicators of the primary indicator “external environment”, the highest weight was seen for natural environment (66.67%), and among the secondary indicators of the primary indicator “internal support”, the lowest weight was seen for the scientific research for visceral leishmaniasis control (8.26%), while other indicators had weights of 12.42% to 13.38%. Among the secondary indicators of the primary indicator “comprehensive control”, the weight was 16.67% for each indicator. Conclusions An evaluation index system has been constructed for the capability of comprehensive control of mountain-type zoonotic visceral leishmaniasis based on the One Health concept. In addition to assessment of the effect of conventional mountain-type zoonotic visceral leishmaniasis control measures, this index system integrates the importance of top-level design, organizational management, and implementation of control measures, and includes indicators related to multi-sectoral cooperation.
ABSTRACT
@# Ebola virus disease (EVD) is a severe infectious disease caused by Ebola virus in humans and primates. The main clinical features are fever and bleeding. The disease was first identified in Zaire and Sudan in Africa in 1976. Since then, it has caused many large-scale epidemics in Africa. One of the largest and most complex Ebola outbreaks in history was the 2014-2016 outbreak in West Africa, which caused more cases and deaths than all previous outbreaks combined. As of 2022, about 35 000 EVD cases and 15 000 deaths have been reported. During the African pandemic, EVD also spread to other regions outside the African continent, such as the Americas and Europe, and became a public health issue of worldwide concern. In Africa, the re-emergence of the disease in Uganda and the Republic of Congo in 2022 has attracted much attention from the world. This article systematically summarizes the history, epidemiological distribution, route of infection, clinical symptoms, diagnosis, treatment, prevention and control of Ebola virus disease, so as to provide reference for relevant workers in China.
ABSTRACT
@# Atypical monkeypox broke out in many non-endemic countries in 2022, and the cumulative number of cases worldwide reached 21 775 on July 11. Although most cases of atypical monkeypox outbreaks were related to sexual behavior, there was no clear consensus on whether monkeypox is a sexually transmitted disease, and the current guidelines issued in China for the diagnosis and treatment of monkeypox do not yet rule out monkeypox as a sexually transmitted disease. This review analyzed the evidence supporting atypical monkeypox as a sexually transmitted disease and other possible explanations from the perspectives of monkeypox case definition/diagnostic criteria, epidemiology, clinical features, laboratory examinations, and public health prevention and control measures, aiming to provide suitable recommendations for the prevention and control of monkeypox outbreaks in China.
ABSTRACT
There are different opinions around the World regarding the zoonotic capability of H3N8 equine influenza viruses. In this report, we have tried to summarize the findings of different research and review articles from Chinese, English, and Mongolian Scientific Literature reporting the evidence for equine influenza virus infections in human beings. Different search engines i.e. CNKI, PubMed, ProQuest, Chongqing Database, Mongol Med, and Web of Knowledge yielded 926 articles, of which 32 articles met the inclusion criteria for this review. Analyzing the epidemiological and Phylogenetic data from these articles, we found a considerable experimental and observational evidence of H3N8 equine influenza viruses infecting human being in different parts of the World in the past. Recently published articles from Pakistan and China have highlighted the emerging threat and capability of equine influenza viruses for an epidemic in human beings in future. In this review article we have summarized the salient scientific reports published on the epidemiology of equine influenza viruses and their zoonotic aspect. Additionally, several recent developments in the start of 21st century, including the transmission and establishment of equine influenza viruses in different animal species i.e. camels and dogs, and presumed encephalopathy associated to influenza viruses in horses, have documented the unpredictable nature of equine influenza viruses. In sum up, several reports has highlighted the unpredictable nature of H3N8 EIVs highlighting the need of continuous surveillance for H3N8 in equines and humans in contact with them for novel and threatening mutations.

ABSTRACT
Hepatitis E virus （HEV） is a pathogen for viral hepatitis and can be transmitted across species via animals. The incidence rate of hepatitis E caused by HEV infection ranks first among acute viral hepatitis worldwide， and now it has become a major public health issue that threatens human health. In recent years， more and more species have been identified as the natural hosts of HEV， and there are more routes for the interspecies transmission of HEV， which greatly inhibits the prevention and control of this virus. Therefore， this article reviews and discusses the advances in the interspecies transmission of HEV， so as to provide a reference for the prevention and control of HEV.
ABSTRACT
Introducción. El síndrome respiratorio agudo grave causado por el nuevo coronavirus SARS-CoV-2 es causa de la emergencia sanitaria por la pandemia de COVID-19. Si bien el humano es el principal huésped vulnerable, en estudios experimentales y reportes de infección natural, se han encontrado casos de zoonosis inversa de SARS-CoV-2 en animales. Objetivo. Evaluar la infección natural por SARS-CoV-2 en gatos y perros de propietarios con diagnóstico de COVID-19 en el Valle de Aburrá, Antioquia, Colombia. Materiales y métodos. La circulación del SARS-CoV-2 se evaluó por RT-qPCR y RT-PCR en muestras de frotis nasofaríngeos y orofaríngeos de gatos y perros cuyos propietarios se encontraban dentro del periodo de los 14 días de aislamiento. Los casos positivos se verificaron amplificando fragmentos de los genes RdRp, N y E; se secuenció el gen RdRp y se analizó filogenéticamente. Resultados. De 80 animales evaluados, seis gatos y tres perros fueron casos confirmados de infección natural por SARS-CoV-2. Los animales no presentaron signos clínicos y sus propietarios, que padecían la infección, reportaron únicamente signos leves de la enfermedad sin complicaciones clínicas. En el análisis de una de las secuencias, se encontró un polimorfismo de un solo nucleótido (SNP) con un cambio en la posición 647, con sustitución del aminoácido serina (S) por una isoleucina (I). Los casos se presentaron en los municipios de Caldas, Medellín y Envigado. Conclusiones. Se infiere que la infección natural en los gatos y perros se asocia al contacto directo con un paciente con COVID-19. No obstante, no es posible determinar la virulencia del virus en este huésped, ni su capacidad de transmisión zoonótica o entre especie.
Introduction: The severe acute respiratory syndrome caused by the new coronavirus SARS-CoV-2 is the cause of the health emergency due to the COVID-19 pandemic. Although humans are the main susceptible host, experimental studies and reported cases of natural infection have evidenced scenarios of SARS-CoV-2 reverse zoonosis in animals. Objective: To evaluate the natural infection of SARS-CoV-2 in cats and dogs with owners diagnosed with COVID-19 in the Valle de Aburrá subregion in Antioquia, Colombia. Materials and methods. The circulation of SARS-CoV-2 was evaluated by RT-qPCR and RT-PCR in samples of nasopharyngeal and oropharyngeal smears from cats and dogs whose owners presented latent COVID-19 infection. Positive cases were verified through amplification of N, E and RdRp gene fragments; with the latter being sequenced and the phylogenetically analyzed. Results. From 80 tested animals, 6 cats and 3 dogs resulted positive for natural SARS-CoV-2 infection. These animals did not show any clinical signs; and their infected owners only reported mild signs of COVID-19, without clinical complications. Regarding analysis of one of the sequences, a single nucleotide polymorphism (SNP) was found, with a substitution in position 647, resulting in the change of the amino acid serine (S) for isoleucine (I). The cases occurred in the municipalities of Caldas, Medellín and Envigado. Conclusions. It is inferred that natural infection in cats and dogs is associated with direct contact with a positive COVID-19 patient.

Background: As per Livestock Census 2019, Banaskantha district shares 9.4% of livestock of Gujarat. About 80–83% of farmers practicing dairy farming in Banaskantha district have low to medium level of knowledge about zoonotic diseases. The practice of handling livestock and its determinants among different populations of Banaskantha district is yet to be studied. Aim and Objectives: The aim of the study was to assess level of awareness and hygienic practice of handling livestock and its determinants among the livestock handlers of Banaskantha district. Materials and Methods: This cross-sectional study was conducted among 172 livestock handlers of nine villages of Banaskantha district. The questionnaire included demographics, knowledge about zoonotic diseases, and practices for handling livestock. One score was given for correct knowledge and practice and “zero” score was given for incorrect knowledge and practice. There were maximum 20 scores for knowledge and practice each. Results: Livestock handlers were well aware of rabies but knowledge of other zoonotic disease was very less. Average knowledge and practice score was 12.76 and 12.39 out of 20, respectively. About 1/3rd of livestock handlers (33.1%) were following hygienic practice very well. Practice score was higher in male livestock handlers and those who received training and livestock handlers with more number of animals. Conclusion: Practice of use of gloves, not using milk during treatment of cattle, testing of animal before purchase, and safe disposal of infected material were very less prevalent. Training should be focused on conveying the importance of correct practicing especially to female livestock handlers with few numbers of animals.
ABSTRACT
Infectious diseases are a significant burden on the global economy and public health. The major factors attributed to the rise in infectious diseases are thought to be the unstructured rise in the human population with expanding poverty, unplanned urbanization, fast urban migration, unplanned human habitats in thickly populated urban pockets that are the residence of poor people, insufficient healthcare infrastructure, inadequate vaccination, and neglect in effectively containing the zoonotic diseases, among others. Certain global regions such as China, India, Bangladesh, Pakistan, and Indonesia among the other Asian countries, sections of South America, and vast parts of Sub-Saharan Africa harbor more infectious human diseases. To contain the infectious disease burden, the health infrastructure especially in poor countries needs to be improved. With the assistance of rich countries monetarily as well as technologically, the situation can be improved. International institutions and large philanthropic organizations are working to improve human health globally. More monetary assistance to these organizations would positively contribute to the cause and would go a long way in diffusing the infectious agents.
ABSTRACT
Tuberculosis (TB) caused by Mycobacterium tuberculosis is a leading cause of human deaths due to any infectious disease worldwide. However, infection of Mycobacterium bovis, primarily an animal pathogen, also leads to the development of ‘human tuberculosis’. Infected animals have been considered the major source of M. bovis infection and humans get exposed to M. bovis through close contact with infected animals or consumption of contaminated milk, unpasteurized dairy products and improperly cooked contaminated meat. The information on the global distribution of bovine TB (bTB) is limited, but the disease has been reported from all the livestock-producing middle- and low-income countries of the world. In recent years, there is a renewed interest for the control of bTB to minimize human infection worldwide. In India, while the sporadic presence of M. bovis has been reported in domestic animals, animal-derived food products and human beings from different geographical regions of the country, the information on the national prevalence of bTB and transmission dynamics of zoonotic TB is, however, not available. The present article reviewed published information on the status of M. bovis-induced zoonotic TB to highlight the key challenges and opportunities for intervention to minimize the risk of M. bovis infection in humans and secure optimum animal productivity in India.
ABSTRACT
Introduction: Several viral diseases with epidemic potential are currently threatening global health security. One of them is Monkeypox. It is an emerging zoonotic infection which is caused by the monkeypox virus. In the past, this disease used to be primarily detected in West and Central Africa. However, the current upsurge of cases outside the African region has led the world to explore the causes that have led to the current situation. Aim and objectives of this study was to explore the reasons for the current upsurge and describe the epidemiology of the disease. The keywords below were used to search from public da Material and Methods: tabases and review the relevant publications on Monkeypox disease and its epidemiology. This search was further used to analyse and summarise the findings into tables and other graphical representation of the data. Monkeypox cases are currently being reported Result and Conclusion: from non-endemic countries e.g. USA, UK, Belgium, France, Germany, Italy, Netherlands, Portugal, Spain, Sweden, Australia, Canada, Austria, Canary Islands, Israel and Switzerland. There are no reported cases of monkeypox virus in India till date as on 6th June 2022. Cases have mainly but not exclusively been identified amongst men who have sex with men (MSM) seeking care in primary care and sexual health clinics in the range of 22 to 63 years of age. Follow public health measures to prevent another pandemic in the recent future.
ABSTRACT
Abstract: The invention and widely use of organ allotransplantation provides effective treatment of some originally fetal diseases such as liver/kidney failure and has saved million of lives around the globe. However, the scarcity of human organs has caused many patients, who could have been treated, to die while waiting for suitable organs around the world. Pig-to human xenotransplantation provides a potential solution to solve this tough problem. Pig organs have been considered as major sources of xenotransplantation because of the sufficient number of donors, the sizes of organs, and physiologically structural similarities. However, xenotransplantation also has some problems, such as the possibility of spreading animal diseases to human, the interspecies immunological barrier, organs of animal origin challenging human nature, and potential informed consent issues. This article will discuss these potential issues and to see whether it is the suitable time to conduct clinical xenotransplantation trials in humans.
Resumen: La invención y el amplio uso de trasplantes alógenos proporciona tratamiento efectivo de algunas enfermedades de origen fetal, como la insuficiencia renal y hepática, y ha salvado a millones de pacientes en el mundo. Sin embargo, la escasez de órganos humanos ha causado que muchos pacientes en el mundo, que podrían haber sido tratados, murieran por esperar un órgano adecuado. El xenotrasplante del cerdo al humano proporciona una solución potencial para resolver este difícil problema. Los órganos de cerdo han sido considerados como fuentes mayores para xenotrasplantes debido al suficiente número de donantes, el tamaño de los órganos y estructuras fisiológicas similares. No obstante, el xenotrasplante también tiene algunos problemas, como la posibilidad de expandir enfermedades animales a humanos, la barrera inmunológica entre especies, el desafío para la naturaleza humana de tener órganos de origen animal y problemas potenciales de consentimiento informado. Este artículo discute estos temas potenciales y plantea si estamos en un momento apropiado para realizar ensayos clínicos de xenotrasplantes en humanos.
Resumo: A invenção e amplo uso de alotransplante de órgãos propicia tratamento efetivo para algumas doenças originalmente fetais tais como falência hepática/renal e tem salvo milhões de vidas em todo o globo. Entretanto, a escassez de órgãos humanos tem causado a morte de muitos pacientes que poderiam ter sido tratados - aguardando por órgãos apropriados em todo o globo. Xenotransplante porco-para-humanos propicia uma solução potencial para resolver este difícil problema. Órgãos de porco tem sido considerados como as principais fontes de xenotransplante por causa do número suficiente de doadores, do tamanho dos órgãos e de similaridades estruturais fisiológicas. Entretanto, xenotransplante também tem alguns problemas, tais como a possibilidade de disseminar doenças animais aos humanos, a barreira imunológica entre espécies, órgão de origem animal desafiando a natureza humana e aspectos potenciais de consentimento informado. Esse artigo discutirá esses aspectos potenciais e verificará se é o momento adequado para conduzir ensaios clínicos de xenotransplante em humanos.

Resumen La brucelosis es una zoonosis desatendida y un problema de salud pública en países en desarrollo, que también causa grandes pérdidas económicas en la ganadería. En México es endémica y Chiapas un estado al sur del país, destaca por la presencia de la enfermedad en humanos. Por medio de la revisión del estado del arte, se encontró que factores como la alta producción de ganado bovino, las limitadas estrategias institucionales de control de la enfermedad en el ganado, la falta de regulación sanitaria del género Brucella en productos lácteos y cárnicos y la ubicación del estado de Chiapas en la frontera con Centroamérica, podrían ser condicionantes para la prevalencia de brucelosis humana en esta región de México.
Abstract Brucellosis is a neglected zoonosis and a public health problem in developing countries that also causes great economic losses in livestock. In Mexico it is endemic and Chiapas, a state in the south of the country, stands out for the presence of the disease in humans. Through the review of the state of the art it was found that factors such as the high production of cattle, the limited institutional strategies to control the disease in livestock, the lack of sanitary regulation of the genus Brucella in dairy and meat products and the location of the state of Chiapas on the border with Central America could be determining factors for the prevalence of human brucellosis in this region of Mexico.

The study reveals the prevalence of a potential rodent-borne zoonotic helminth species, Hymenolepis diminuta in commensal rodents caught from irrigated and rain-fed areas of Swat, Pakistan. Three hundred and fifty rodents (269 rats and 81 mice) trapped during vegetative, flowering/fruiting and mature/harvesting stages of crops were studied from 2011-2013. Hymenolepisdiminuta eggs were identified on the basis of their shape, size, colour and markings on the surface of the egg shell and three pairs of embryonic hook-lets. Overall prevalence of H. diminuta was 3.14% (n=11/350). The highest prevalence 3.49% (n=5/143) of H. diminuta was noted at harvesting stages of the crops whereas the lowest 2.59% (n=2/77) during vegetative stage. Infection was higher in males 3.25% (n=7/215) than females 2.96% (n=4/135). Adult rodents were highly infected while no sub-adult was found infected. Infection was higher in mice 3.70% (3/81) than rats 2.69% (8/269) while no significance (p=1.0000:0.1250 to 32.00 CI). Rats and mice appears to show the most suitable reservoirs by hosting H. diminuta a zoonotic helminth. The presence of these rodents in all possible habitats can act as a main channel of transferring parasites through various habitats and can pose a hazard to humans in the area.
O estudo revela a prevalência de uma espécie potencial de helmintos zoonóticos transmitidos por roedores, Hymenolepis diminuta, em roedores comensais capturados em áreas irrigadas e alimentadas pela chuva de Swat, Paquistão. Trezentos e cinquenta roedores (269 ratos e 81 camundongos) presos durante os estágios vegetativo, floração/frutificação e maturidade/colheita das safras foram estudados de 2011-2013. Ovos de Hymenolepis diminuta foram identificados com base em sua forma, tamanho, cor e marcações na superfície da casca do ovo e três pares de anzóis embrionários. A prevalência geral de H. diminuta foi de 3,14% (n = 11/350). A maior prevalência 3,49% (n = 5/143) de H. diminuta foi observada na fase de colheita das lavouras, enquanto a menor 2,59% (n = 2/77) durante a fase vegetativa. A infecção foi maior nos homens 3,25% (n = 7/215) do que nas mulheres 2,96% (n = 4/135). Roedores adultos foram altamente infectados, enquanto nenhum subadulto foi encontrado infectado. A infecção foi maior em camundongos 3,70% (3/81) do que em ratos 2,69% (8/269), embora sem significância (p = 1,0000: 0,1250 a 32,00 CI). Ratos e camundongos parecem mostrar os reservatórios mais adequados hospedando H. diminuta um helmintos zoonótico. A presença desses roedores em todos os habitats possíveis pode atuar como um canal principal de transferência de parasitas através de vários habitats e pode representar um perigo para os humanos na área.
