RESUMO
Objective: This study aimed to identify the primary mucocutaneous manifestations secondary to Monkeypox infection and determine the prevalence of coinfection with other sexually transmitted infections (STIs).Methods: Searches were conducted in the PubMed, LILACS, SciELO, Cochrane Library, and Virtual Health Library databases using the descriptors "monkeypox," "dermatological," "dermatology," "cutaneous," "skin," and "mucocutaneous," combined with the Boolean operators "and" and "or." All articles published between January 2017 and October 2022 that addressed mucocutaneous manifestations secondary to Monkeypox infection, regardless of language, were included. Technical notes from the Brazilian Ministry of Health and World Health Organization recommendations were also incorporated. The Joanna Briggs Institute (JBI) critical appraisal tool was used to assess the quality of the studies. Data were independently evaluated by three reviewers. Exclusion criteria included the absence of photographic records of the lesions, lack of laboratory confirmation of infection, "letter to the editor" publications, duplicates, and articles primarily focused on systemic manifestations without association with the integumentary system.Results: A total of 22 publications were included in this study. The most frequently affected anatomical sites were the genital and perianal regions, though lesions were also reported on the torso, face, oropharynx, limbs, palms, and soles. There is a possibility that the infection may present nonspecifically as a maculopapular rash. Lesions are typically multiple, with either localized or widespread distribution. In the latter case, the progression is centrifugal, beginning on the face. The most prevalent characteristic of the elementary lesion is central umbilication, which eventually develops a crusted appearance. Umbilicated papules are often associated with pain, which gradually transitions to varying degrees of pruritus. Coinfection with HIV and other STIs was particularly notable among men who have sex with other men and/or have multiple partners and who use condoms inconsistently.Conclusions: Monkeypox can present with various cutaneous manifestations, none of which are pathognomonic of the disease. The chronological evolution of the elementary lesions (papule, vesicle, pustule, crust) is not always precise, with multiple stages potentially coexisting in the same area of the body. The primary behavioral factor associated with infection is unprotected sexual activity, especially among men who have sex with other men. Coinfections with HIV, syphilis, gonorrhea, chlamydia, and/or herpes were observed in the majority of cases (AU)
Resumo A "varíola dos macacos" é uma zoonose causada pelo vírus Monkeypox, que se manifesta por sinais e sintomas sistêmicos inespecíficos e lesões cutâneo-mucosas do tipo molusco. Em 2022, a incidência de casos aumentou exponencialmente a nível mundial.Objetivos: Identificar as evidências disponíveis na literatura acerca das principais manifestações cutâneo-mucosas secundárias à infecção pelo vírus, descritas após a propagação da doença, bem como a prevalência da coinfecção com outras infecções sexualmente transmissíveis e comportamentos de risco.Métodos: Foram realizadas buscas nas bases de dados Medline via PubMed, LILACS, SciELO, Biblioteca Cochrane e Biblioteca Virtual em Saúde utilizando os descritores "monkeypox", "dermatological", "dermatology", "cutaneous", "skin" e "mucocutaneous" com os operadores lógicos booleanos "and" e "or". Foram incluídos todos os artigos publicados entre janeiro de 2017 e outubro de 2022, cujas temáticas envolviam manifestações mucocutâneas secundárias à infecção pelo Monkeypox, em todos os idiomas disponíveis. Também incorporamos notas técnicas do Mi-nistério da Saúde brasileiro e recomendações da Organização Mundial da Saúde. A ferramenta de avaliação crítica usada para determinar a qualidade dos estudos foi o Joanna Briggs Institute (JBI). Os dados foram avaliados por três revisores de forma independente.Critérios de exclusão: Ausência de registro fotográfico das lesões, ausência de confirmação laboratorial da infecção, publicações do tipo "carta ao editor", duplicatas e publicações cujo foco eram manifestações sistêmicas sem associação ao sistema tegumentar.Resultados: Foram incluídas 22 publicações no estudo. Os sítios anatômicos mais acometidos pela zoonose foram as regiões genital e perianal, mas também houve relatos de lesões cutâneas no tronco, face, orofaringe, membros, palmas e plantas. Existe a possibilidade, pouco comum, de a infecção se apresentar de forma inespecífica, como rash maculopapular. Em geral, as lesões são múltiplas, com distribuição localizada ou disseminada neste caso, com progressão centrífuga, iniciada na face. O aspecto mais prevalente da lesão elementar inicial é a umbilicação central, que, com o passar do tempo, adquire aspecto crostoso. A coinfecção com HIV e outras infecções sexualmente transmissíveis foi relevante, especialmente em homens que fazem sexo com homens e que usam preservativo de forma irregular.Conclusões: Há inúmeras possibilidades de manifestações cutâneas da infecção pelo Monkeypox, sendo nenhuma delas patognomônica da zoonose. A ordem cronológica da evolução das lesões elementares (pápula, vesícula, pústula, crosta) não é regra. Vários estágios diferentes podem coexistir numa mesma área corporal. O principal fator comportamental envolvido é a atividade sexual desprotegida. A coinfecção com HIV, sífilis, gonorreia, clamídia e/ou herpes ocorreu em grande parte dos casos (AU)

We studied the organization of the inferior parietal cortex (IPC) in five capuchin monkey (6 hemispheres) using cytoarchitectonic (Nissl), myeloarchitectonic (Gallyas), and immune-architectonic (SMI-32 monoclonal antibody) techniques. We partitioned the IPC into five distinct areas: PFG, PG, Opt, PFop, and PGop. Since we used parasagittal sections, we were not able to study area PF due to its far lateral position, which yielded slices that were tangential to the pial surface. Areas PFG, PG, and Opt were in the convexity close to the lateral sulcus, while PFop and PGop were positioned more posteriorly, in the opercular region of IPC. Of all the five regions, area Opt was the one most similar to its analogue in the macaque, especially as revealed with SMI-32 staining. Namely, in both primate species area Opt showed a low density of large pyramidal neurons. Additionally, the apical dendrites of these neurons were sparse and vertically orientated, resembling columns. We also found area PG to be similar: both species exhibited cell body layers with a radial arrangement. On the other hand, Nissl staining revealed area PFG to be architectonically different between New and Old-World monkeys: PFG in the capuchin showed a comparatively higher cell density than in macaques, especially in layers II and IV. These results suggest that evolution may have enabled the functional specialization of these brain regions based on behavioral demands of upper limb use. The small differences in the IPC of the two primates may be linked to interspecies variability.

Reaction time is accelerated if a loud (startling) sound accompanies the cue-the "StartReact" effect. Animal studies revealed a reticulospinal substrate for the startle reflex; StartReact may similarly involve the reticulospinal tract, but this is currently uncertain. Here we trained two female macaque monkeys to perform elbow flexion/extension movements following a visual cue. The cue was sometimes accompanied by a loud sound, generating a StartReact effect in electromyogram response latency, as seen in humans. Extracellular recordings were made from antidromically identified corticospinal neurons in primary motor cortex (M1), from the reticular formation (RF), and from the spinal cord (SC; C5-C8 segments). After loud sound, task-related activity was suppressed in M1 (latency, 70-200 ms after cue), but was initially enhanced (70-80 ms) and then suppressed (140-210 ms) in RF. SC activity was unchanged. In a computational model, we simulated a motoneuron pool receiving input from different proportions of the average M1 and RF activity recorded experimentally. Motoneuron firing generated simulated electromyogram, allowing reaction time measurements. Only if ≥60% of motoneuron drive came from RF (≤40% from M1) did loud sound shorten reaction time. The extent of shortening increased as more drive came from RF. If RF provided <60% of drive, loud sound lengthened the reaction time-the opposite of experimental findings. The majority of the drive for voluntary movements is thus likely to originate from the brainstem, not the cortex; changes in the magnitude of the StartReact effect can measure a shift in the relative importance of descending systems.SIGNIFICANCE STATEMENT Our results reveal that a loud sound has opposite effects on neural spiking in corticospinal cells from primary motor cortex, and in the reticular formation. We show that this fortuitously allows changes in reaction time produced by a loud sound to be used to assess the relative importance of reticulospinal versus corticospinal control of movement, validating previous noninvasive measurements in humans. Our findings suggest that the majority of the descending drive to motoneurons producing voluntary movement in primates comes from the reticulospinal tract, not the corticospinal tract.

Since the explosive outbreak of Zika virus in Brazil and South/Central America in 2015-2016, the frequency of infections has subsided, but Zika virus remains present in this region as well as other tropical and sub-tropical areas of the globe. The most alarming aspect of Zika virus infection is its association with severe birth defects when infection occurs in pregnant women. Understanding the mechanism of Zika virus pathogenesis, which comprises features unique to Zika virus as well as shared with other teratogenic pathogens, is key to future prophylactic or therapeutic interventions. Nonhuman primate-based research has played a significant role in advancing our knowledge of Zika virus pathogenesis, especially with regard to fetal infection. This review summarizes what we have learned from these models and potential future research directions.

BACKGROUND: Recently, some studies about primates have claimed the importance of the vessels to maintain the muscles working; in fact, the arterial supply could suggest how strenuous the muscular performance is associated to locomotor behavior. The aim of this work was to study the anatomy of the arteries of the forelimbs of different groups of primates to evidence a general arterial model in comparative terms. METHODS: We propose a biophysical explanation for the arterial pattern of the forelimbs of primates' groups. RESULTS: Three pattern of the forelimb arteries in Primates were descript and the differences were explained using mathematical formulas. CONCLUSIONS: The anatomical study about the comparative anatomy of the arteries of the forelimbs of primates provided hypothesis about the three observed models, mainly in relation to brachial artery division and the number of the palmar arches, in mathematical models' terms.

BACKGROUND: The past years have seen increased appreciation of electroencephalographic (EEG) recordings in non-human primates (NHP) as a tool for translational research. In humans, even large EEG electrode grids can easily and quickly be placed on standardized positions using commercially available EEG caps. In the NHP, the identification of standardized EEG electrode positions is more complicated and time-consuming. NEW METHOD: Here we introduce a surface metric and software package (NHP1020) that automates the planning of large, approximately evenly spaced electrode grids for EEG recordings in the NHP. RESULTS: Based on one CT and one MRI image as well as two intracranial markers, the NHP1020 software defines electrode positions on the brain surface using a surface-based spherical metric similar to the one used by the international 10-20 system. Standardized electrode grids can be shared, imported or defined with few high-level commands. EXISTING METHODS: NHP EEG electrodes can be placed relative to extracranial markers and measurements or relative to underlying neural structures of interest. Both approaches are time-consuming and require manual intervention. Furthermore, the use of extracranial markers in this species may be more problematic than in humans, because cranial muscles and ridges are larger and keep maturing long into adulthood. CONCLUSION: The presented surface metric and the NHP1020 toolbox provide fast and automated identification of entire electrode grids in the non-human primate based on a two-dimensional metric on the brain surface.

Live-attenuated V4020 vaccine for Venezuelan equine encephalitis virus (VEEV) containing attenuating rearrangement of the virus structural genes was evaluated in a non-human primate model for immunogenicity and protective efficacy against aerosol challenge with wild-type VEEV. The genomic RNA of V4020 vaccine virus was encoded in the pMG4020 plasmid under control of the CMV promoter and contained the capsid gene downstream from the glycoprotein genes. It also included attenuating mutations from the VEE TC83 vaccine, with E2-120Arg substitution genetically engineered to prevent reversion mutations. The population of V4020 vaccine virus derived from pMG4020-transfected Vero cells was characterized by next generation sequencing (NGS) and indicated no detectable genetic reversions. Cynomolgus macaques were vaccinated with V4020 vaccine virus. After one or two vaccinations including by intramuscular route, high levels of virus-neutralizing antibodies were confirmed with no viremia or apparent adverse reactions to vaccinations. The protective effect of vaccination was evaluated using an aerosol challenge with VEEV. After challenge, macaques had no detectable viremia, demonstrating a protective effect of vaccination with live V4020 VEEV vaccine.

This work aimed to describe the skeletopy of the medullary cone of the capuchin monkey (Sapajus apella) and to lay morphological foundations to propose a route of administration for epidural anesthesia. We used five females adults S.apella, and dissected them to study their medullary cone. The fixated animals were dissected, a skin incision was made from the dorsal median line, epaxial musculature and vertebral arcs was removed to expose the spinal cord, individualizing the medullary cone and the lumbar intumescence. The base of S. apella medullary cone was located near the L5 vertebra and the apex near S3, the structure was 4.5 cm in average. The evaluated specimens presented five lumbar and four sacral vertebrae. We concluded that the positioning of S. apella medullary cone is caudally than in other species, suggesting that the most appropriate location for epidural anesthetic procedures is the sacrocaudal region.
Este estudo visa descrever a esqueletopia do cone medular em macaco prego (Sapajus apella), com a intenção de estabelecer bases morfológicas para prestar o apoio à implementação de procedimentos anestésicos e outros procedimentos de rotina clínica-cirúrgica veterinária, dada a crescente importância do papel do veterinário na saúde dos animais selvagens. Cinco S. apella adultos fêmeas foram utilizadas neste trabalho e dissecados para o estudo do cone medular. Os animais fixados foram dissecados, foi feita uma incisão na pele na linha média dorsal, a musculatura epaxial e os arcos vertebrais foram removidos para exposição da medula espinhal, individualizando o cone medular e a intumescência lombar. A base do cone medular do S. apella foi observada na altura da vértebra L5 com o ápice em S3, com comprimento médio de 4,5 cm. Os espécimes avaliados apresentaram cinco vértebras lombares e quatro sacrais. Conclui-se que o posicionamento do cone medular do S. apella é mais caudal em relação às outras espécies. Por conseguinte, é sugerido que o local mais apropriado para o procedimento anestésico peridural é a sacrocaudal região.

Feline night monkey (Aotus azarae infulatus) is an arboreal primate that sleeps during the day hidden among branches of trees, leaving its hideout after nightfall. Little is known about the morphology of these animals, which leads to some difficulty in clinical and surgical approaches, as there has been substantial growth in the veterinarian's role in maintaining the health and well-being of wildlife. Thus, we sought to investigate the topography and morphometry of the medullary cone, a small portion of the nervous system of the feline night monkey, which is of paramount importance in approaches for epidural anesthesia. Specimens from five young females were used, each with eight lumbar vertebrae, three sacral vertebrae, and a medullary cone with an average length of 7.5 cm, located between L5 and S3. Based on this finding, we suggest that a probable site for the application of epidural anesthesia is the space between S3 and Cc1.
O macaco-da-noite (Aotus azarae infulatus) é um animal arborícola que dorme durante o dia escondido entre os ramos, saindo do esconderijo após o anoitecer. Pouco se sabe sobre a morfologia destes animais, o que gera certa dificuldade nas abordagens clínico-cirúrgicas, uma vez que cresce substancialmente o papel do médico veterinário nas questões de saúde e bem-estar de animais selvagens. Visando contribuir com esses profissionais, buscou-se investigar a topografia e morfometria de uma pequena porção do sistema nervoso do macaco-da-noite, o cone medular, que é de suma importância nas abordagens quanto à anestesia peridural. Foram utilizados cinco espécimes fêmeas, jovens, de macaco-da-noite, que apresentavam oito vértebras lombares e três vértebras sacrais, e cone medular possuindo em média de 7,5 cm de comprimento, localizando-se entre L5 e S3. Este achado nos leva a sugerir como sítio provável para a aplicação de anestesia epidural, o espaço entre S3 e Cc1.

In multi-female multi-male group-living species, both sexes can copulate with diverse partners. According to the priority of access model, high-ranking males have higher access to females during their fertile phases than the lower-ranking competitors. However, when females' ovarian cycles are synchronized, dominant males are unable to monopolize all females, which gives a chance to lower ranking males to sporadically copulate and increase their likelihood to fertilize a female. Therefore, subordinate males perhaps show physiological characteristics allowing them to contend with the advantage that the dominant males already have. It was investigated if sperm counts, weight of the seminal coagulum, and testosterone levels showed any differences according to their social rank in male stump-tailed macaques. Testosterone levels increased linearly in relation to social rank (Pâ¯=â¯0.004). No evidence was found that in the first ejaculation dominant rank was positively related to sperm counts and weight of the seminal coagulum. In the second ejaculation a positive correlation between dominant rank and sperm counts and weight of the seminal coagulum was found (Pâ¯<â¯0.001). By the third ejaculation there was a negative correlation between sperm counts and dominant rank (Pâ¯<â¯0.001), but no variability in the weight of the seminal coagulum. The results showed that high-rank is related to better physiological conditions to sustain multiple ejaculations, thanks to having higher testosterone levels.

En Paraguay, no se han registrado casos autóctonos de malaria desde el 2011. Se realizó un estudio descriptivo observacional transversal en 6 monos y 23 aves que vivían en una región históricamente endémica de Paraguay para buscar presencia de reservorios silvestres de parásitos plasmodios causantes de la malaria. El ADN se extrajo por el método de Chelex a partir de una gota de sangre en un papel de filtro, y la detección del parásito se realizó mediante la PCR múltiple semianidada. Por este método, no se detectaron parásitos en ninguna de las 29 muestras. Se evaluó el riesgo potencial de circulación selvática de los parásitos que causan la malaria. Teniendo en cuenta la presencia de mosquitos anofelinos vectores en la zona, el hecho de que no se hayan observado casos positivos es un buen indicador teniendo en cuenta que nuestro país fue declarado recientemente como país libre de malaria por la OMS(AU)
In Paraguay, autochthonous cases of malaria have not been recorded since 2011. A cross-sectional observational descriptive study was conducted in 6 monkeys and 23 birds living in a historically endemic region of Paraguay to identify wild reservoirs of plasmodium parasites that cause malaria. DNA was extracted by the Chelex method from a blood drop in a filter paper, and parasite detection was performed by the seminested multiplex PCR. By this method, parasites were not detected in any of the 29 samples. The risk of potential sylvatic circulation of the parasites causing malaria was evaluated. Considering the presence of anopheline mosquitoes in the area, the fact that we did not find any positive cases is a good indicator as our country was recently certified as a malaria-free country by the WHO(AU)

The aim of the present study was to evaluate the growth rate of Balantidium coli in three xenic media cultures. Between 2013 and 2015, 10 B. coli isolates obtained from feces of Cynomolgus macaques, and 30 isolates from feces of pigs were studied. An inoculum of 500 trophozoites was transferred to tubes containing LES, TYSGM-9 and Pavlova media. These cultures were evaluated at incubation times of 24, 48, 72 and 96 hours. In most of strains analyzed wasn't showed significant difference in the growth rate comparing TYSGM-9 and Pavlova media (Wilcoxon p>0.016). In Pavlova medium, the trophozoites showed a maximum growth at 72 hours with significant difference when compared with the times of 24 h and 96 h (Wilcoxon <0.008). In LES, viable trophozoites were observed until 24 hours, with a significant difference (Friedman p<0.05, Wilcoxon p<0.016) in the number of parasite cells compared with Pavlova and TYSGM-9 media cultures. Thus, LES medium seemed to be less adequate than the other media for maintenance of B. coli. Despite the satisfactory results in TYSGM-9, Pavlova medium was considered ideal for the maintenance of this protozoan strain, guaranteeing the viability of the parasite with subculture every three days, presenting lower costs.

Resumo O objetivo do presente estudo foi avaliar a taxa de crescimento de Balantidium coli em três meios de cultura xênicos. Entre 2013 e 2015 foram estudados 10 isolados de B. coli obtidos de Cynomolgus macaques e 30 isolados de suínos. Um inóculo contendo 500 trofozoítos foi transferido para tubos contendo os meios LES, TYSGM-9 e Pavlova. Os cultivos foram avaliados com tempos de incubação de 24, 48, 72 e 96 horas. Na maioria das cepas analisadas não foi observado diferença significativa na taxa de crescimento comparando TYSGM-9 e Pavlova (Wilcoxon p>0,016). Em Pavlova, os trofozoítos apresentaram máximo de crescimento a 72 h com diferença significativa quando se comparou com os tempos de 24 h e 96 h (Wilcoxon <0,008). Em LES observou-se trofozoítos viáveis até 24 horas com diferença significativa (Friedman p<0,05 e Wilcoxon p<0,016), na quantidade de células parasitárias, quando comparado com Pavlova e TYSGM-9. Dessa forma, o meio LES mostrou-se ser menos adequado do que os outros, para a manutenção de B. coli. Apesar do resultado satisfatório em TYSGM-9, Pavlova foi considerado ideal para manutenção do protozoário, por garantir a viabilidade do parasito com subcultivos a cada três dias, além de apresentar menor custo.

Although the breeding seasonality in Macaca arctoides have been studied over a long period of time, it is still controversial whether reproduction in this primate tend to increase during certain months of the year as it happens in most of the macaque species. Many authors have classified Macaca arctoides as not being seasonal species. Nonetheless, there were no reports, about seasonal variations of female sexual hormones to demonstrate that asseveration. Therefore, in the present study we collect 1611 fecal samples from June 2009 to November 2010 from 10 female stump-tailed macaques to measure 17ß-estradiol and progesterone concentrations. Also, we included the birth frequency per year, in order to identify if sexual hormones peaked at a certain period of the year, thus, births would be occurring six months later according to the gestation length of stump-tailed macaques. Our results indicate two mating seasons per year in stump-tailed macaques: one in July-August and a second one in November. The distribution of the birth frequency, throughout the year support these results. We conclude that stump-tail macaques have a discrete seasonality no different than most of macaques' species.

BACKGROUND: The anatomical literature on the genus Macaca has focused mainly on the rhesus monkey. However, some aspects in the positional behaviors of the Japanese monkey may be different from those in rhesus monkey, suggesting that the anatomical details of these species are divergent. METHODS: Four thoracic limbs of Macaca fuscata adults were dissected. RESULTS: The arm muscles in Japanese macaques are more similar to rhesus monkeys and Papio; these characteristics are closer to those of bearded capuchins than apes, indicating more proximity of this genus to New World primates. CONCLUSIONS: The anatomical features observed favor quadrupedal locomotor behaviors on the ground and in arboreal environments. Japanese monkeys, rhesus monkeys, and bearded capuchins, which share more primitive characteristics in their arm muscles, present features that favor both arboreal and quadrupedal locomotor behaviors, whereas apes, mainly Pan and Gorilla, which spend more time on the ground, present more quadrupedal specializations.

Relata-se o emprego da técnica de bloqueio de plexo braquial em um bugio (Alouatta 16 caraya), macho, com aproximadamente 1 ano de idade. O animal apresentava queimadura extensa, abrangendo o terço distal do antebraço e mão direita em consequência de choque elétrico. Após avaliação clínico-cirúrgico, recomendou-se a amputação do membro. O protocolo anestésico constituiu de contenção química com a associação de cetamina, midazolan e clorpromazina, seguido da indução e manutenção da anestesia com isofluorano. O bloqueio do plexo braquial, com lidocaína, teve como referência a palpação do pulso da artéria axilar. Durante o procedimento cirúrgico o animal permaneceu com as frequências cardíaca e respiratória estáveis e teve boa recuperação pós-anestésica. A associação da anestesia geral inalatória com bloqueio locorregional com anestésico local assegurou a estabilidade transoperatória e conforto pós-anestésico imediato.
This is a report of the use of brachial plexus block technique on a black howler (Alouatta caraya), male, approximately 1 year. The animal had extensive burn, covering the distal third of the right forearm and hand due to electric shock result. After clinical and surgical evaluation, it is recommended limb amputation. The anesthetic protocol included a chemical restraint with ketamine, midazolam and chlorpromazine, followed by induction and maintenance of anesthesia with isoflurane. The brachial plexus block was performed with lidocaine, and had reference the pulse palpation of the axillary artery. During the surgical procedure, the animal remained with heart and respiratory rates stable and had good post-anesthetic recovery. The association of inhalation anesthesia with regional blockade with local anesthetic provide intraoperative stability and comfort post anesthetic immediately

PROBLEM/CONDITION: Melioidosis is an infection caused by the Gram-negative bacillus Burkholderia pseudomallei, which is naturally found in water and soil in areas endemic for melioidosis. Infection can be severe and sometimes fatal. The federal select agent program designates B. pseudomallei as a Tier 1 overlap select agent, which can affect both humans and animals. Identification of B. pseudomallei and all occupational exposures must be reported to the Federal Select Agent Program immediately (i.e., within 24 hours), whereas states are not required to notify CDC's Bacterial Special Pathogens Branch (BSPB) of human infections. PERIOD COVERED: 2008-2013. DESCRIPTION OF SYSTEM: The passive surveillance system includes reports of suspected (human and animal) melioidosis cases and reports of incidents of possible occupational exposures. Reporting of suspected cases to BSPB is voluntary. BSPB receives reports of occupational exposure in the context of a request for technical consultation (so that the system does not include the full complement of the mandatory and confidential reporting to the Federal Select Agent Program). Reporting sources include state health departments, medical facilities, microbiologic laboratories, or research facilities. Melioidosis cases are classified using the standard case definition adopted by the Council of State and Territorial Epidemiologists in 2011. In follow up to reports of occupational exposures, CDC often provides technical assistance to state health departments to identify all persons with possible exposures, define level of risk, and provide recommendations for postexposure prophylaxis and health monitoring of exposed persons. RESULTS: During 2008-2013, BSPB provided technical assistance to 20 U.S. states and Puerto Rico involving 37 confirmed cases of melioidosis (34 human cases and three animal cases). Among those with documented travel history, the majority of reported cases (64%) occurred among persons with a documented travel history to areas endemic for melioidosis. Two persons did not report any travel outside of the United States. Separately, six incidents of possible occupational exposure involving research activities also were reported to BSPB, for which two incidents involved occupational exposures and no human infections occurred. Technical assistance was not required for these incidents because of risk-level (low or none) and appropriate onsite occupational safety response. Of the 261 persons at risk for occupational exposure to B. pseudomallei while performing laboratory diagnostics, 43 (16%) persons had high-risk exposures, 130 (50%) persons had low-risk exposures, and 88 (34%) persons were classified as having undetermined or unknown risk. INTERPRETATION: A small number of U.S. cases of melioidosis have been reported among persons with no travel history outside of the United States, whereas the majority of cases have occurred in persons with a travel history to areas endemic for melioidosis. If the number of travelers continues to increase in countries where the disease is endemic, the likelihood of identifying imported melioidosis cases in the United States might also increase. PUBLIC HEALTH ACTIONS: Reporting of melioidosis cases can improve the ability to monitor the incidence and prevalence of the disease in the United States. To improve prevention and control of melioidosis, CDC recommends that (1) physicians consider melioidosis in the differential diagnosis of patients with acute febrile illnesses, risk factors for melioidosis, and compatible travel or exposure history; (2) personnel at risk for occupational exposure (e.g., laboratory workers or researchers) follow proper safety practices, which includes using appropriate personal protective equipment when working with unknown pathogens; and (3) all possible occupational exposures to B. pseudomallei be reported voluntarily to BSPB.
