Starting September 1, 2023, WLSB initiated a new reimbursement procedure. WLSB now
tracks all Wyoming State
Veterinary Lab (WSVL) brucellosis test records for the purposes of reimbursement. For test records that meet
requirements for reimbursement, WLSB will create a monthly reimbursement invoice and electronically send the
invoice, test records, and current W-9 to the veterinarian or facility for verification. Your invoice will be sent from
one of the following email addresses: email@example.com or firstname.lastname@example.org. The veterinarian/facility
will review the documents, note any required changes, and acknowledge approval to WLSB for processing. WLSB
will finalize the documents and submit the packet for payment. Payment is issued in the form of a mailed check or
direct deposit, per payee preferences.
Incomplete Paperwork Fee
In July, we adopted a new fee schedule at WSVL.
Hereby, we would like to remind you that per our fee schedule, there will be a fee for incomplete paperwork requiring phone calls to clients, as well as a handling fee for samples that are sent out to referral labs.
Currently, we have not implemented these fees, however, we would like to inform you that starting October 1, 2023, we will add these charges to our invoices as applicable.
The antibiogram is a summary of antimicrobial susceptibilities of bacterial isolates submitted to WSVL. We will provide annual antibiograms to assist our clients in determining antibiotic therapy prior to knowing the susceptibility information.
This week, the Wyoming State Veterinary Laboratory (WSVL) has diagnosed Yersinia pestis, the bacteria responsible for Plague, in an Albany County cat. The cat is an indoor/outdoor pet who hunts rodents. It is responding well to treatment and no human illness has been reported with the case. So far in 2023, two cats and a prairie dog have tested positive for Plague in the State of Wyoming. Plague is a serious infection that is deadly for people and pets if not immediately treated with antibiotics. See the distribution map at the link in the title.
Tularemia is another bacterial infection that is a serious threat to humans and pets. In 2023, the WSVL has diagnosed four cases of Tularemia in pets and wildlife in Wyoming. Both Plague and Tularemia are transmitted to pets from ingesting infected animals or fleas bites coming from infected animals. Symptoms of infection include fever, lethargy, coughing, swollen lymph nodes, especially under the jaw, and decreased appetite. Vomiting and diarrhea are also possible. Recommendations for prevention are keeping fleas off of indoor and outdoor pets by applying flea control products. Animals that free roam outdoors are more likely to contact plague or tularemia infected animals. If pets appear sick, seek veterinary care as soon as possible.
During the month of August and the end of July, the Wyoming State Veterinary Laboratory (WSVL) has detected serologic and PCR evidence of West Nile Virus (WNV) in 24 equine submissions from 10 Wyoming counties. In the past 5 years and in comparison to this year, the laboratory has detected lower numbers of cases serologically. 2018 also had increased detection numbers with acute phase antibody detection in 14 equine submissions. From 2019 to 2022, there were a total of 11 cases with detected WNV acute phase antibodies (2019- 3 cases, 2020- 0 cases, 2021- 5 cases and 2022- 3 cases). In the past 5 years, WNV has not been detected with PCR in any equine submissions. See the distribution map at the title link.
West Nile Virus is transmitted by mosquitos. WNV affects humans and other animals, especially birds and horses. Affected animals can present with a variety of clinical signs varying from no clinical disease to potential lethal encephalitis, inflammation in the brain. Horses can recover from infection but can be left with long term side effects. Many of the recent WY cases have had a variety of neurologic signs, including generalized or hind-end weakness, lethargy, incoordination and stumbling as well as muscle twitching, drooping head and abnormal sensitivity to outside stimuli. Some of the horses have had a fever and most of the horses have either no or a poor vaccine history. Annual vaccination is the best form of protection as well as implementation of mosquito control and decreased exposure to mosquitos.
The Wyoming State Veterinary Laboratory (WSVL) has isolated Streptococcus equi ssp. equi in three separate cases from Southeastern Wyoming during the month of August. The related bacterial disease is also known as Strangles. Strangles is a reportable highly contagious upper respiratory disease in horses that can present with nasal discharge and abscessed lymph nodes. Transmission of the bacteria happens generally from nose-to-nose contact with infected horses but can also occur with shared tack and feed containers.
Since 2020, 38 cases of strangles have been detected at our lab, out of 11 different Wyoming counties (please see case map at the link in the title). While there is no clear seasonality, we already detected 9 cases in 2023.
