I couldn't find anything specific to CL in guinea pigs. However, I did find Group C Streptococcus incubation periods in other animal species, such as fowl and horses. Group C Streptococcal incubation periods in these animals ranged from 1 day to 2 weeks. One source went so far as to say "several weeks". I would think a Group C Streptococcal infection in guinea pigs would have a similar incubation period.
Sources recommend either culling or isolating infected animals before lymph node abscesses rupture to prevent spread of organism.
For infected animals that are isolated, the following treatment is recommended:
* Treat with surgical drainage of lymph nodes
* Lavage abscesses
* Antibiotic therapy for 7-14 days.
"Diseases of Domestic Guinea Pigs" recommends 14 days of daily administration of Cephaloridine at 25mg/kg body weight intramuscularly or Cephalexin at 50-100mg/kg intramuscularly.
"Merck Vet Manual" recommends Cephaloridine at 25 mg/kg body intracuscularly daily but it is not said for how long treatment is to continue. They have reported this to be effective in controlling and eliminating the disease.
Important note: I believe Cephaloridine and Cephalexin to be Cephalosporins. Cephalosporins are listed on the Guinea Lynx "Dangerous Medications" list.
Affected animals should stay isolated until abscesses have drained and healed.
I couldn't find anything specific to guinea pigs, but in horses with
Streptococcus equii, another Group C Streptococcus which causes "Strangles" (similiar to CL in guinea pigs), the total time for the disease to run its course was approximately 3 weeks.
In other animal species, Streptococcal spp. have been isolated from them for as long as 4 weeks after symptoms of disease have gone. Would that guinea pigs continue to shed Streptococcus zooepidemicus for this length of time after their abscesses have drained and healed, I do not know.
There has been some indication that there can be carrier animals.
* Limiting the amount of coarse feed may aid in decreasing incidence of CL.
* Chronic infections can be exacerbated by stress.
* One source (sorry, don't remember which one) said the Group C Streptococcus is relatively fragile in the environment. I take this to mean that it wouldn't live long outside a host.
As far as finding out who is a carrier, I couldn't find any specific method to determine this. All I found out was that there could be carrier animals.
I'm going to look into Baytril's efficacy against Streptococcus.

Under Cervical Lymphadenitis:
Enrofloxacin is Baytril. No dose recommendations or length of treatment recommendations given.Systemic antibiotics such as enrofloxacin or chloramphenical are effective.
I'm going to have to get off the computer now. I think husband is getting annoyed that I've spent so much time on here today. I hope some of this has helped, though.
Someone please come take all these pigs away. I don't want to do this anymore.
I wish I could be there to help. You are in my thoughts.
- I GAVE, dammit!
I have a torn lumbar disc in my back, and what do I do? Ship hay! All this past week I;'ve been standing and canning fruits and vegetables, and painting the back two bedrooms, along with moving all the furniture.
I'm living on Advil and Flexeril. Nuts I tell ya.
Chary, I really feel your pain, girl. Hang in there. Tomorrow will look brighter.
I take it you chose bleach over the toilet plunger? that was your first mistake...back to making piggie masks, I guess.
It would seem most of the information you've found agrees with each other. I'd go with VC Richardson's suggestion of baytril before I'd use the other drugs though.

Yes, tomorrow is another day and hopefully a lot brighter and happier for you. Take it easy and remember every one of those piggies love you.
- My home, ruled by pigs!
I hope you are able to get something for the pain so you can at least function and get some help.
