Diseases Of The Middle And Inner Ear

Normal Anatomy and Physiology The middle ear consists of the tympanic membrane, three cavities (epitympanic, tympanic, and ventral), and the bony ossicles (malleus, incus, and stapes). The tympanic membrane has two parts: (1) the thin pars tensa that attaches to the manubrium of the malleus and (2), above the pars tensa, the thicker, pars flaccida.… Read More »

Amphotericin B Desoxycholate, Amphotericin B Lipid-Based (Abelcet, Fungizone)

Antifungal Highlights Of Prescribing Information • Systemic antifungal used for serious mycotic infections • Must be administered IV • Nephrotoxicity is biggest concern, particularly with the deoxycholate form; newer lipid based products are less nephrotoxic & penetrate into tissues better, but are more expensive • Renal function monitoring essential • Amphotericin B Desoxycholate, Amphotericin B… Read More »

Amikacin Sulfate (Amikin, Amiglyde-V)

Aminoglycoside Antibiotic Highlights Of Prescribing Information • Parenteral aminoglycoside antibiotic that has good activity against a variety of bacteria, predominantly gram-negative aerobic bacilli • Adverse Effects: Nephrotoxicity, ototoxicity, neuromuscu-lar blockade • Cats may be more sensitive to toxic effects • Risk factors for toxicity: Preexisting renal disease, age (both neonatal & geriatric), fever, sepsis &… Read More »

Embryo Collection

Equine embryos are selectively transported through the oviduct into the uterus between days 5 and 6 postovulation (ovulation = day 0), at which time they are at the late morula to early blastocyst stage of development. In contrast unfertilized oocytes remain trapped in the oviduct where they degenerate over a period of several months. Although… Read More »

Embryo Storage

Two options exist to store equine embryos. The short-term (<24 hours) method entails storage of embryos that are cooled to 5° C in an Equitainer (Hamilton Research, South Hamilton, Mass.). The long-term (>24 hours) method involves storage of embryos that are frozen at -196° C in liquid nitrogen. Of these two options, short-term storage procedures… Read More »

Cryopreservation of Semen

The use of frozen-thawed equine semen has increased greatly over the past 10 to 15 years. The use of this type of semen can have tremendous advantages for both stallion and mare owners. Genetic material can be stored indefinitely and may be used even after the death of the stallion. Success in the cryopreservation of… Read More »

Drugs Acting On The Reproductive System

Drugs used to promote gonadal function Sex hormones Prostaglandins Myometrial stimulants Myometrial relaxants Prolactin antagonists Non-hormonal abortificants Drugs for uterine infections Many drugs are used at different stages of the oestrous cycle to manage the response of the reproductive system; these are summarised in Table Drags affecting the reproductive system. Table Drags affecting the reproductive… Read More »

Oomycetes

Pythium insidiosum Oomycetes: Cause Pythium insidiosum is an aquatic oomycete that causes severe gastrointestinal pathology in a range of hosts in the tropic and subtropic climates. Based on ribosomal RNA gene sequence data, members of the Class Oomycetes are phylogenetically distinct from the Kingdom Fungi and are more closely related to algae than to fungi.… Read More »

Drugs used in the treatment of Mastitis

Mastitis is of economic importance in dairy cows because it causes decreased milk quality and reduced milk yield, which often leads to early culling. Peracute mastitis often results in death. Other species affected include sheep, pigs, dogs, cats, goats, and horses; male animals may also be affected. Treatment of mastitis in sheep and goats is… Read More »

Preparations for non-lactating animals

Non-lactating or dry cow therapy is administered to eliminate any subclinical infection present at the end of lactation and to prevent the establishment of new infections, including summer mastitis, during the dry period. Management plays a major part in the control of mastitis during the dry period and animals should be examined frequently, preferably twice… Read More »
