Practice questions
- A veterinarian assesses a worker with possible tuberculosis after frequent close contact with infected cattle. Which organism is the zoonotic tuberculosis agent specifically emphasized in the occupational-exposure review?
- A person regularly consumes unpasteurized milk from a herd with M. bovis infection. Which route of zoonotic exposure is most directly implicated?
- Which occupational group is explicitly identified as potentially exposed to M. bovis through close interaction with cattle or wildlife?
- A hunter has a wound that is exposed to infected animal tissue. Which M. bovis transmission route described in the review is most relevant?
- A clinician evaluating possible zoonotic TB asks about aerosol exposure during close work with infected cattle. Which route is supported by the occupational-exposure review?
- Which prevention approach best reflects the review's account of M. bovis risk at the human–animal interface?
- A patient reports eating raw freshwater fish and later develops an illness suspected to be due to an intestinal fluke. Which group is associated with this exposure in the review?
- Consumption of aquatic vegetables is reported in the history of a patient with suspected foodborne intestinal fluke infection. Which pairing is supported by the review?
- A patient has eaten amphibians and reptiles in an area where foodborne intestinal flukes occur. Which parasite is specifically associated with this exposure in the review?
- Which food exposure is associated with Gymnophalloides seoi in the review of foodborne intestinal flukes?
- In a patient with suspected intestinal flukiasis, which antiparasitic drug is reported as highly effective against most intestinal fluke species?
- A parasitology review classifies foodborne intestinal flukes into 28 heterophyid species, 23 echinostome species, and 23 species in miscellaneous groups. What total does this classification imply?
- A patient is diagnosed with cysticercosis caused by Taenia solium. Which exposure is identified as the cause of cysticercosis in the molecular-epidemiology review?
- A researcher compares mitochondrial and nuclear markers in T. solium populations. Which distinction matches the molecular-epidemiology review?
- Molecular studies of T. solium reported hybrids between two broad genotypes in Madagascar. What inference did the review draw from this finding?
- An epidemiologist uses parasite genetic variation alongside geographic data to investigate where an infection may have been acquired. Which approach is described in the T. solium review?
- In a reviewed canine tuberculosis case, culture is pending and may take weeks to months. Which test is listed among the adjunctive techniques used in canine cases?
- A dog has suspected tuberculosis, but culture is not yet available. According to the canine case review, which method is the reference standard for diagnosis?
- A dog with confirmed MTBC infection has predominantly abdominal signs. In the case groups used by the canine TB review, what proportion of cases were primarily abdominal?
- A canine MTBC case is fully speciated. Which set contains the three organisms reported as causes in the canine case review?
- A researcher reviewing canine TB reports finds that cultures can take weeks to months to report. What is the main diagnostic implication highlighted by the review?
- In a study of Diptera captured on nine dairy farms, which fly family was most prevalent among the 217 collected specimens?
- A laboratory report from the dairy-fly study lists 70 Enterococcus isolates among 275 identified microorganisms. Which interpretation uses the correct denominator?
- A zoonotic bacterium is cultured from a fly collected in a milking environment. What conclusion is justified by the finding alone?
- A laboratory plans work with a high-priority zoonotic pathogen. Which set contains the evidence domains specifically identified by the Biosafety Research Road Map as needing attention?
- A laboratory proposes maximal facility restrictions for every pathogen, regardless of task-specific evidence. Which interpretation best aligns with the Biosafety Research Road Map review?
