Valley Fever (VF), caused by fungi in the genus , is a prevalent disease in southwestern and western parts of the United States that affects both humans and animals, such as dogs. Although the immune responses to infection with spp. are not fully characterized, antibody-detection assays are used in conjunction with clinical presentation and radiologic findings to aid in the diagnosis of VF.

Natural infection virtually always confers protection from future exposure, and this suggests that a preventative vaccine strategy is likely to succeed.

On arrival, calves received either a two-course regimen of ceftiofur crystalline free acid (CCFA) followed by tulathromycin 8 days later (Group 1) or a one-course regiment of CCFA (Group 2) or tilmicosin (Group 3). At Site A, morbidity was significantly lower (52%) in Group 1 than in Group 2 (76.

Animals: 17 lactating Holstein dairy cows.
Procedure: Daily IM injections of ceftiofur sodium were administered at a dose of 2.
Objective: To evaluate the efficacy of ceftiofur hydrochloride sterile suspension administered parenterally for treatment of acute postpartum metritis (APM) in dairy cows.
Design: Multilocation, randomized block, field trial.
Animals: 406 cows in the first 14 days postpartum.
Seven well-controlled studies conducted under multiple management conditions demonstrated that ceftiofur, a late-generation veterinary parenteral cephalosporin, is effective for the treatment of bovine foot rot in beef and dairy cattle. Two preliminary dosage titration studies using a challenge model compared the efficacy of ceftiofur (1.1 mg or 2.

The DHP emulsified in lecithin emulsion administered subcutaneously caused a substantial increase in body temperature, total leukocyte count, total neutrophil count, neutrophil cytochrome-c reduction, and neutrophil iodination 24 hours after administration and, for some of the parameters, at 48 hours.

A study was designed to evaluate average daily gain (ADG) and feed efficiency (FE) for cattle through 140 days in the feedlot after CCFA-SS was administered concurrently in the same ear with a growth-promoting implant. On Day 0, steers (n = 207) averaging 189 kg in weight were randomly assigned to the following treatments: Revalor -S implant (120 mg trenbolone acetate and 24 mg estradiol per implant; Hoechst-Roussel Agri-Vet Company) (n = 64); CCFA-SS at 6.

In each study, CCFA-SS was administered once by subcutaneous (SC) injection in the middle third of the posterior aspect of the ear. Study 1 was conducted using an intratracheal challenge with Mannheimia (formerly Pasteurella) haemolytica and dosages ranging from 0 to 8.
