Fenbendazole has a broad spectrum of activity.  Besides treating roundworms and hookworms in small animals, it also has activity against both Taenia spp and Dipylidium caninum.

A client brings in their dog, who is suffering  from a chronic cough that is hard and dry.  Sometimes the dog also retches, particularly after exercising.   A bronchoscopy is done and nodules in the trachea are noted, similar to the ones shown below. What nematode is responsible for this pathology?

Heterobilharzia americana, which has dogs as a definitive host, can infect humans and cause swimmer’s itch / swamp itch.

The adult worms of Paragonimus kellicotti and Fasciola hepatica infect the liver of the definitive host.

Why is colonization considered the most difficult step in the metastasis-invasion cascade?

All of the following are stages of trematodes (i.e., flukes), EXCEPT for:

A cat presented at your clinic suffering from chronic coughing, dyspnea, open-mouth breathing, sneezing, wheezing and nasal discharge.  You suspect that the cat is infected with Aelurostrongylus abstrustus.  What is the best test to perform to confirm your diagnosis

For Ollulanus tricuspis, select the TRUE statement

For the liver flukes, Fasciola hepatica & Fascioloides magna, select the FALSE statement.

Overtime hours and productivity: HINT – SEE TABLE 8.4 for this problem The key is to use Table 8.4  (old book 13.8) to determine the. effective labor hours at standard productivity with the x workers given, then convert that to a 40 hour schedule. From the table use the productivity rate for weeks 1 and 2, then for weeks 3 and 4.From Table 8.3 (old book 13.8) for week 1 and 2 effective labor hours or actual hour output for 50-hour weekis 46.3 hours and for week 3 and 4 is 45 hours:For calculating the size of the crew, we should divide total effective labor hours  40-hours times the number of weeks. THE PROBLEM: A project is scheduled to last four weeks. This schedule is based on a crew of 7 workers (Crew A) working 10 hours per day for 5 days per week. The wage is $16 per hour for regular hours. Beyond 8 hours per day or 40 hours per week, the pay is increased by a multiplier of 1.25, i.e., $20 per hour. (a) Determine the number of labor hours actually worked based on this schedule. (Man hours =  _____________) (b) From the table, use the productivity rates for weeks 1 and 2, then 3 and 4 to calculate the effective labor hours at standard productivity. (Effective labor hours = ­­­­______) (c) Calculate the size of the crew (Crew B) required to do a standard 40 hour week over the same 4-week period. (Use whole numbers for the crew size – the weeks can be fractional) (Size of Crew B =___________) (d) Calculate the labor costs of Crew A: (Cost of Crew A =$_____) (e) Calculate the labor cost of Crew B: (Cost of Crew B =$______)
