[h=3]Feds reopen probe into MDR Salmonella tied to calves, cite 10 new cases[/h] Federal officials today said they have reopened their investigation of a multistate outbreak of multidrug-resistant (MDR) Salmonella Heidelberg infections linked to raising calves and have reported 10 new cases.
The investigation was closed on Mar 20 after 36 patients were reported. The new cases are in Kentucky (3 cases), Indiana (2), and Minnesota, Missouri, New Jersey, Ohio, and South Dakota, which all had 1 new case, the Centers for Disease Control and Prevention (CDC) reported. Kentucky, Indiana, New Jersey, and Ohio had not reported cases before. Fourteen states have now reported cases.
Of the 46 outbreak patients, 14 (30%) required hospitalization, but no deaths have been linked to the outbreak. Illnesses began on dates ranging from Jan 27, 2015, to Jul 11. Fifteen of the cases involve children younger than 5 years.
"Epidemiologic and laboratory investigations linked ill people in this outbreak to contact with calves, including dairy bull calves," the CDC said in today's update. "Dairy bull calves are young, male cattle that may be raised for meat."
"Of the 44 people interviewed," the agency added, "29 (66%) reported contact with dairy bull calves or other cattle. Some of the ill people interviewed reported that they became sick after their dairy bull calves became sick or died."
All eight isolates from patients were resistant to amoxicillin-clavulanic acid, ampicillin, cefoxitin, ceftriaxone, streptomycin, sulfisoxazole, and tetracycline and had reduced susceptibility to ciprofloxacin. Seven were also resistant to trimethoprim-sulfamethoxazole, five to nalidixic acid, and three to chloramphenicol. All the isolates, however, were susceptible to gentamicin, azithromycin, and meropenem.
Aug 2 CDC update
[h=3]Texas raises Cyclospora totals to 160 cases[/h] The Texas Department of State Health Services (DSHS) raised the number of Cyclospora parasite cases reported in that state to 160 yesterday, up from the 68 infections it reported on Jul 17.
The DSHS first started reporting cases in mid-June and said it will be monitoring and updating case counts twice per week as the outbreak grows. Bexar and Harris counties have had the most cases, with 23 and 42 cases, respectively.
Infection with the parasite can cause several long-lasting symptoms, including watery diarrhea, loss of appetite, and fatigue. Previous outbreaks have been tied to contaminated produce, but the DSHS has not yet named a likely infection source in this outbreak.
