Fatal Simplexvirus humanalpha1 infection in howler-monkeys (Alouatta sp.) under human care: Clinical, molecular, and pathological findings.

BACKGROUND: Simplexvirus humanalpha1 (HuAHV-1) are common anthropozoonosis reported in marmosets but rare in howler monkeys (Alouatta sp.). METHODS: Necropsy of two brown-howler monkeys (A. caraya) and one red-howler monkey (A. guariba clamitans) from different zoo collections were performed. Fragments of all organs were examined through microscopy. Samples were submitted to IHC for Simplexvirus humanalpha 2 (HuAHV-2) [sin. Herpesvirus simplex type 2] and PCR. RESULTS: Grossly, only the A. guariba showed liver lesions characterized by multifocal, pinpoint white areas corresponding microscopically as random necrotizing herpetic hepatitis and ulcerative glossitis. Both A. caraya showed necrotizing meningoencephalitis with Cowdry A-type body inclusions within neurons and astrocytes. Immunolabeling for HuAHV-1/2 was observed in the tongue, liver, and brain. HuAHV-1 was confirmed in all samples by PCR, Sanger sequencing, and phylogenetic analyses. CONCLUSION: Necrotizing meningoencephalitis was appreciated in 2/3 of animals, and it is associated with neurologic signs. Along with ulcerative glossitis, a hallmark lesion in marmosets, it was present in one animal. Regarding herpetic hepatitis, it is not frequent in monkeys and occurs mainly in immunocompromised animals. HuAHV-1 infection was confirmed corroborating with a human source. This is the second report on captive black-howler monkeys and the first gross, histologic, immunohistochemical, and molecular description of herpetic hepatitis and ulcerative glossitis in red-howler monkeys (A. guariba).

Transmission of SARS-CoV-2 from Human to Domestic Ferret.

We report a case of natural infection with severe acute respiratory syndrome coronavirus 2 transmitted from an owner to a pet ferret in the same household in Slovenia. The ferret had onset of gastroenteritis with severe dehydration. Whole-genome sequencing of the viruses isolated from the owner and ferret revealed a 2-nt difference.

[The system of epidemiological control of hepatitis E and complex of anti-epidemic, hygienic and veterinary sanitary activities in the Belgorod oblast].

The Hepatitis E (HE) is a viral liver disease that is common on all continents at different rates and very frequently is not symptomatically distinguishable from other viral hepatitis, such as hepatitis A, B and C, as well as from other infectious diseases referred to as "acute jaundice syndrome". The GE-anthroponosis (in the case of infection caused by genotypes 1 or 2 of hepatitis E virus) or anthropozoonosis (in the case of infection caused by 3 or 4 viruses) is predominantly propagated through fecal-oral transmission. The article presents the general characteristics of VGE, human risk factors and means of prevention. The particular attention is paid to the development of complex of anti-epidemic, hygienic and veterinary sanitary measures in the Belgorod Oblast.

Abundance of Leishmania (Kinetoplastida: Trypanosomatidae) vectors in Baldim, a municipality in the Espinhaço Range Biosphere Reserve in Brazil.

Leishmaniasis is a zoonoses caused by protozoan parasites belonging to the Leishmania genus that is transmitted to humans through the bite of previously infected phlebotomine sandflies (Diptera:Psychodidae:Phlebotominae). In Brazil, 2 types of leishmaniasis are endemic, tegumentary leishmaniasis (TL) and visceral leishmaniasis (VL). In Baldim, a municipality in the Espinhaço Range Biospere Reserve (ERBR), 5 autochthonous cases of TL, and one autochthonous case of VL were reported from 2017 to 2022. Owing to the lack of data on entomological fauna, we surveyed the occurrence and distribution of phlebotomine sandflies that could act as Leishmania vectors, as well as natural Leishmania infection. During 1 year, 918 sandfly specimens belonging to 12 species were collected. The predominant species was Lutzomyia longipalpis (Lutz & Neiva, 1912) (32.0%), a proven VL agent, followed by Evandromyia evandroi (Costa Lima & Antunes, 1936) (20.7%), Evandromyia cortelezzii (Brèthes, 1923) (17.0%), Nyssomyia whitmani (Antunes & Coutinho, 1939) (12.2%), and Nyssomyia intermedia (Lutz & Neiva, 1912) (10.5%), all putative or proven TL agents. Seasonal fluctuations and endo-exophilic behavior were delineated for the main phlebotomine sandflies. The population of Lu. longipalpis was higher during the coolest and driest months, although different profiles were noted for the other species. Natural Leishmania infection was not detected in any of the 197 phlebotomine sandfly females analyzed. The results were compared with those previously obtained in other municipalities belonging to the ERBR. The presence of Leishmania vectors and human cases of leishmaniasis indicate a risk of Leishmania transmission in the region.

Role of Free-Ranging Synanthropic Egyptian Geese (Alopochen aegyptiaca) as Natural Host Reservoirs for Salmonella spp. in Germany.

Salmonella is one of the most common and pathogenic bacteria worldwide, causing severe enteritis in humans and representing a relevant intestinal illness in One Health for young, old and immunosuppressed patients. Various Salmonella serovars have been described to be responsible for human Salmonellosis. Birds represent natural carriers of different zoonotic-relevant Salmonella serovars and Anseriformes can not only transmit Salmonella spp. to humans but also manifest clinical Salmonellosis. In this study, 138 scat samples (n = 138) of free-ranging Egyptian geese (EG; Alopochen aegyptiaca) were collected in Germany, including 83 scat samples from city parks, 30 samples from 14 public swimming pools and 25 fresh caecal samples of dead EG. Collected EG scat samples were examined for the presence of Salmonella spp. according either to the ISO 6579 (2017) norm or to a combination of bacterial pre-enrichment and specific PCR for detection of Salmonella DNA. All 138 analysed EG faecal samples resulted Salmonella-negative. Furthermore, the survival of Salmonella enterica subsp. enterica Serovar Anatum in spiked EG droppings was tested in four different concentrations of chlorinated pool water. In vitro testing demonstrated that S. Anatum-spiked EG droppings were still infectious for up to six hours in chlorinated pool water according to current German regulations for public swimming pools. This study is to be considered as a baseline investigation to clarify the role of synanthropic EG as natural carriers of zoonotic Salmonella in cities; nonetheless, large-scale epidemiological studies, including higher numbers of samples as well as more urban locations, are needed for final conclusions on the occurrence of this intestinal bacteria in neozootic EG.

Seroprevalence of exposure to SARS-CoV-2 in domestic dogs and cats and its relationship with COVID-19 cases in the city of Villavicencio, Colombia.

Background: Since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, different animal species have been implicated as possible intermediate hosts that could facilitate the transmission of the virus between species. The detection of these hosts has intensified, reporting wild, zoo, farm, and pet animals. The goal of this study was to determine the seroprevalence of anti-SARS-CoV-2 immunoglobulins (IgG) in domestic dogs and cats and its epidemiological association with the frequency of coronavirus disease 2019 (COVID-19) patients in Villavicencio, Colombia. Methods: 300 dogs and 135 cats were randomly selected in a two-stage distribution by clusters according to COVID-19 cases (positive RT-qPCR for SARS-CoV-2) within the human population distributed within the eight communes of Villavicencio. Indirect enzyme-linked immunosorbent assay (ELISA) technique was applied in order to determine anti-SARS-CoV-2 IgG in sera samples. Kernel density estimation was used to compare the prevalence of COVID-19 cases with the seropositivity of dogs and cats. Results: The overall seroprevalence of anti-SARS-CoV-2 IgG was 4.6% (95% CI=3.2-7.4). In canines, 3.67% (95% CI=2.1-6.4) and felines 6.67% (95% CI=3.6-12.18). Kernel density estimation indicated that seropositive cases were concentrated in the southwest region of the city. There was a positive association between SARS-CoV-2 seropositivity in pet animals and their habitat in Commune 2 (adjusted OR=5.84; 95% CI=1.1-30.88). Spearman's correlation coefficients were weakly positive ( p=0.32) between the ratio of COVID-19 cases in November 2020 and the results for domestic dogs and cats from the eight communes of Villavicencio. Conclusions: In the present research cats were more susceptible to SARS-CoV-2 infection than dogs. This study provides the first positive results of anti-SARS-CoV-2 ELISA serological tests in domestic dogs and cats in Colombia with information about the virus transmission dynamics in Latin America during the COVID-19 pandemic.

Mink, SARS-CoV-2, and the Human-Animal Interface.

Mink are small carnivores of the Mustelidae family. The American mink is the most common and was imported to Europe, Asia, and Latin America for breeding, as its fur is very popular. Denmark, the Netherlands, and China are the biggest producers of mink. Mink farms with a high population density in very small areas and a low level of genetic heterogeneity are places conducive to contagion. The mink's receptor for SARS-CoV-2 is very similar to that of humans. Experimental models have shown the susceptibility of the ferret, another mustelid, to become infected with SARS-CoV-2 and to transmit it to other ferrets. On April 23, 2020, for the first time, an outbreak of SARS-CoV-2 in a mink farm was reported in the Netherlands. Since then, COVID-19 has reached numerous mink farms in the Netherlands, Denmark, United States, France, Greece, Italy, Spain, Sweden, Poland, Lithuania, and Canada. Not only do mink become infected from each other, but also they are capable of infecting humans, including with virus variants that have mutated in mink. Human infection with variant mink viruses with spike mutations led to the culling in Denmark of all mink in the country. Several animals can be infected with SARS-CoV-2. However, anthropo-zoonotic outbreaks have only been reported in mink farms. The rapid spread of SARS-CoV-2 in mink farms raises questions regarding their potential role at the onset of the pandemic and the impact of mutants on viral fitness, contagiousness, pathogenicity, re-infections with different mutants, immunotherapy, and vaccine efficacy.

A Review on SERS-Based Detection of Human Virus Infections: Influenza and Coronavirus.

The diagnosis of respiratory viruses of zoonotic origin (RVsZO) such as influenza and coronaviruses in humans is crucial, because their spread and pandemic threat are the highest. Surface-enhanced Raman spectroscopy (SERS) is an analytical technique with promising impact for the point-of-care diagnosis of viruses. It has been applied to a variety of influenza A virus subtypes, such as the H1N1 and the novel coronavirus SARS-CoV-2. In this work, a review of the strategies used for the detection of RVsZO by SERS is presented. In addition, relevant information about the SERS technique, anthropozoonosis, and RVsZO is provided for a better understanding of the theme. The direct identification is based on trapping the viruses within the interstices of plasmonic nanoparticles and recording the SERS signal from gene fragments or membrane proteins. Quantitative mono- and multiplexed assays have been achieved following an indirect format through a SERS-based sandwich immunoassay. Based on this review, the development of multiplex assays that incorporate the detection of RVsZO together with their specific biomarkers and/or secondary disease biomarkers resulting from the infection progress would be desirable. These configurations could be used as a double confirmation or to evaluate the health condition of the patient.

Hydatid cyst in the neck, an unusual localization of the disease: A case report.

INTRODUCTION AND IMPORTANCE: Hydatid cyst disease or hydatidosis is an old parasitic disease. Humans represent an accidental intermediate host. Neck is considered a rare location of hydatid cysts. It is usually overlooked as a deferential diagnosis in any cystic lesion in the neck, even in the regions where the disease is considered endemic. CASE PRESENTATION: A 26 year old female was admitted to Al-Mouwasat Hospital with the complaint of an anterior cervical mass causing compressive symptoms. Examinations determined a big cystic lesion at expense of the thyroid gland and extended to the level of aortic arch, in addition to smaller lesions in the two thyroid lobes. Multinodular goiter was diagnosed. However, Hydatid cyst disease was suspected during surgery. Cystectomy and total thyroidectomy were performed. Histopathology confirmed the diagnosis of hydatid cyst disease. CLINICAL DISCUSSION: Hydatid cyst disease in the neck is usually asymptomatic unless it compresses near structures. Histopathological study makes the definitive diagnoses. The best treatment of thyroid hydatid cysts is total surgical excision of all cysts with intensive care not to spread the disease. CONCLUSION: Hydatid cyst disease in the neck is extremely rare. Hydatid cyst should be included in differential diagnosis of cystic lesions in the neck especially in patients from endemic countries. Post-operative surveillance is important to diagnose the complete healing or recurrence of hydatid disease in operated or other locations but also for follow up of replacement therapy after total thyroidectomy as the patient require lifelong thyroid hormone replacement.

Are adenoviruses zoonotic? A systematic review of the evidence.

Adenoviruses (AdVs) are major contributors to clinical illnesses. Novel human and animal AdVs continue to be identified and characterized. Comparative analyses using bioinformatic methods and Omics-based technologies allow insights into how these human pathogens have emerged and their potential for host cross-species transmission. Systematic review of literature published across ProQuest, Pubmed, and Web of Science databases for evidence of adenoviral zoonotic potential identified 589 citations. After removing duplicates, 327 citations were screened for relevance; of which, 74 articles received full-text reviews. Among these, 24 were included here, of which 16 demonstrated evidence of zoonotic transmission of AdVs. These documented instances of AdV crossing host species barriers between humans and non-human primate, bat, feline, swine, canine, ovine, and caprine. Eight studies sought to but did not find evidence of zoonosis. The findings demonstrate substantial evidence suggesting AdVs have previously and will continue crossing host species barriers. These have human health consequences both in terms of novel pathogen emergence and epidemic outbreaks, and of appropriate and safe use of non-human adenoviruses for therapeutics. As routine human clinical diagnostics may miss a novel cross-species adenovirus infection in humans, next generation sequencing or panspecies molecular diagnostics may be necessary to detect such incursions.

Applied Institutional Approaches for the Evaluation and Management of Zoonoses in Contemporary Laboratory Animal Research Facilities.

Zoonoses, diseases transmitted between animals and humans, have been a concern in laboratory animal medicine for decades. Exposure to zoonotic organisms not only poses health risks to personnel and research animals but may also affect research integrity. Early laboratory animal programs were ineffective at excluding and preventing transmission of zoonotic diseases: the health status of the animals were often unknown, endemic diseases occurred frequently, housing conditions were less controlled, and veterinary care programs were decentralized. Over time, these conditions improved, but despite this, zoonotic diseases remain a contemporary concern. To reduce the incidence of zoonoses, management should perform an accurate risk assessment that takes into account the type of research performed, animal species used, animal sources, and housing conditions. Specific research practices, such as the use of biological materials, can also affect the risk assessment and should be considered. Once identified, the characteristics of significant zoonotic organisms can be examined. In addition, personnel attitudes and training, facility design and management, equipment availability, personal protective equipment used, standard operating procedures, and the institution's vermin control program can impact the risk assessment. The effectiveness of the occupational health and safety program at managing risks of zoonoses should also be examined. Risk assessment, in the context of zoonotic disease prevention, is a complex exercise and is most effective when a team approach is used and includes research, husbandry, veterinary, and biosafety personnel.

Pre-Multidrug-Resistant Mycobacterium tuberculosis Infection Causing Fatal Enteric Disease in a Dog from a Family with History of Human Tuberculosis.

This report describes a fatal case of a pet dog with major enteric signs owned by a family that has experienced cases of pulmonary tuberculosis (TB) in the household. Clinical and epidemiological aspects, imaging data, microbiological, haematological and histopathological examinations were assessed to diagnosis of disease. gyrB-RFLP, spoligotyping and MIRU-VNTR allowed molecular detection of M. tuberculosis strain from S family. The resazurin microtiter assay indicated that all isolates were resistant to isoniazid, ethambutol, ciprofloxacin, ofloxacin, streptomycin and amikacin. The public health concerns related to canine tuberculosis and risk of the dissemination by pets of M. tuberculosis pre-multidrug-resistant (PMD) to isoniazid, ethambutol and other first-line drugs used in human therapy of TB are discussed. We believe this to be the first report of PMD M. tuberculosis infection in a dog presenting mainly enteric manifestation, confirmed as S lineage by molecular methods, owned by a family in which TB has spread in the household for generations.

Risk factors for leptospirosis and brucellosis in people living with human immunodeficiency virus who attended a referral hospital in southeastern Brazil

Abstract INTRODUCTION: Leptospirosis and brucellosis cause immunosuppression that worsens the clinical condition of people living with HIV/AIDS (PLWHA). We investigated the serological profile and risk factors of PLWHA. METHODS: Serum samples (n=238) were researched for Brucella spp. antibodies using Rose Bengal and tube agglutination tests and Leptospira spp. antibodies using the microscopic agglutination test. RESULTS: All samples were negative for Brucella spp. For leptospirosis, four samples (1.69%) were positive, and Andamana was the prevalent serovar. CONCLUSIONS: Low or no detection of these zoonoses does not reduce their importance in PLWHA. Vigilant, educational, and preventive measures should be adopted.

Leishmaniose visceral em um Pastor Belga: relato de caso / Visceral leishmaniasis in a Belgian Pastor: case report

O presente trabalho tem como objetivo relatar um caso de um Pastor Belga, do município de Ponta Porã, Mato Grosso do Sul, positivo para Leishmaniose Visceral, atendido em 2017 em uma clínica veterinária localizada em Pedro Juan Caballero, Paraguai. O diagnóstico foi confirmado através dos sinais clínicos característicos, e dos exames ELISA e PCR positivos. O animal foi submetido ao tratamento clínico para melhora dos sintomas, cujo tratamento antiparasitário inicial foi realizado com a associação de estibogluconato de sódio 75 mg/kg e alopurinol 100 mg seguido de aloputinol 100mg de uso contínuo e uso da coleira antileishmaniose. Tratamento esse considerado eficiente, com melhora clínica do animal. Após 24 meses o animal foi diagnosticado com tumor de mama e lesão da bolsa escrotal, sendo submetido a tratamento clínico e cirúrgico. Com 30 e 36 meses do diagnóstico inicial repetiu-se os exames ELISA (positivo) e PCR (negativo), e então o animal foi considerado curado clinicamente devido à ausência de sinais clínicos. Tendo em vista a complexidade dos fatores no ciclo de transmissão, conclui-se que as medidas em saúde ainda são insuficientes para o controle efetivo da doença. É importante o papel do Médico Veterinário na saúde pública, devido a obrigatoriedade de notificação de casos de Leishmaniose Visceral Canina, sendo necessários esforços nas diferentes áreas da saúde animal, humana e do meio ambiente, visando medidas de vigilância e controle da doença no país.

The present work aims to report a case of a Belgian Shepherd, from the municipality of Ponta Porã, Mato Grosso do Sul, positive for Visceral Leishmaniasis, treated in 2017 in a veterinary clinic located in Pedro Juan Caballero, Paraguay. The diagnosis was confirmed through the characteristic clinical signs, and the positive ELISA and PCR tests. The animal was submitted to clinical treatment for improvement of symptoms, whose initial antiparasitic treatment was performed with the association of sodium stibogluconate 75 mg/kg and allopurinol 100 mg followed by alloputinol 100mg of continuous use and use of the antileishmaniasis collar. This treatment was considered efficient, with clinical improvement of the animal. After 24 months the animal was diagnosed with a breast tumor and scrotum injury, and was submitted to clinical and surgical treatment. At 30 and 36 months from the initial diagnosis, the ELISA tests (positive) and PCR (negative) were repeated, and then the animal was considered clinically cured due to the absence of clinical signs. Considering the complexity of the factors in the transmission cycle, it is concluded that the health measures are still insufficient for the effective control of the disease. The role of the veterinarian in public health is important, due to the obligatory notification of cases of Canine Visceral Leishmaniasis, being necessary efforts in the different areas of animal health, human and environment, aiming at measures of surveillance and control of the disease in the country.

Seroprevalence and occupational risk survey for Coxiella burnetii among exposed workers in Sicily, Southern Italy.

OBJECTIVES: The aim of this survey was to assess the seroprevalence of antibodies against Coxiella burnetii (C. burnetii) in subjects at risk of exposure in Sicily, Southern Italy. MATERIAL AND METHODS: Prevalence of IgG antibodies to C. burnetii phase II antigens was evaluated by ELISA in a group of 140 workers at risk of exposure (38 veterinarians, 38 slaughterhouse workers, 44 livestock handlers, 20 laboratory and technical personnel) included in a medical surveillance program and in 42 control subjects. Positive samples were classified as suggestive of prior exposure to C. burnetii. RESULTS: Antibodies against C. burnetii were detected in 88 out of 140 (62.9%) exposed workers and in 6 out of 42 (14.3%) subjects of the control group. The variables evaluated did not seem to have a significant effect on seropositivity to Coxiella with the exception of symptoms in the last 6 months preceding the survey. CONCLUSIONS: Our study demonstrated a high seroprevalence of C. burnetii in the group of exposed workers in comparison to non-exposed subjects of the control group. Clinical illness appears to be rare; nevertheless, physicians should consider Q fever in patients with compatible symptoms and occupational exposure to animals and their products. As aerosols represent the main route of infection in animals and humans, these workers are strongly advised to wear respiratory masks. In addition, occupational physicians should consider routine serologic evaluation and vaccination of occupationally exposed workers.
