In addition,tooits chelating effect and ability toweaken the cell wall of gram negative bacteria, Triz-EDTA ear drop solution can also inactivate the Pseudomonas efflux pumps of bacteria. Efflux pumps cause antibiotics to be actively pumped out of the bacteria. This is a common mechanism for causing the development of antibiotic resistance. By inactivating the efflux pumps, the sensitivity to antibiotic is improved. Individual bouts of otitis externa can be managed using polyvalent topical ear products with a glucocorticoid (for mild acute inflammation), an antibiotic, and an antifungal (for Malassezia). Cleaning is necessary in cases with large amounts of debris. Biofilms can be physically broken up and removed by thorough flushing and aspiration. TrizEDTA and 2% n-acetylcysteine can disrupt biofilms. Systemic n-acetylcysteine (NAC; 600 mg q 12 h) can help dissolve biofilms in the middle ear and other mucous surfaces. NAC and bromhexine can help drainage of mucus in PSOM and feline inflammatory otitis media. Malassezia yeast organisms are often secondarily present in patients with chronic ear disease. Malassezia otitis typically results in variable degrees of inflammation and excessive, malodorous, mostly brown to dark-brown, waxy discharge. Of note, however, the number of Malassezia organisms seen during cytologic examination does not always correlate with the severity of clinical signs. Malassezia organisms not only have the ability to increase hyperplasia and secretion by proteins and enzymes they produce but also may be able to trigger an immune response, resulting in severe inflammation and potentially hypersensitive reaction. 5 The diagnostic test of choice to confirm Malassezia infection is cytology. Fungal culture is not recommended because Malassezia organisms are usually not resistant to antimicrobials such as azoles, the organism does not grow well on regular fungal culture media, and standardized susceptibility testing is not available. 5

This product is very safe for routine use in dogs when there is no infection present or even to use prior to applying ear medications if your dog has a bacterial or yeast/fungal infection,” according to Woodley. “It contains numerous drying agents like salicylic acid that will help keep the ear canals dry and help prevent ear infections, like yeast, from occurring. It’s a great product to have on hand, especially if your dog likes swimming. You can use this afterward to help clean out excess water from the ear canals and dry them out naturally.” Otodine — Otodine is an ear cleansing detergent used to treat chronic otitis externa. The product contains 0.15% chlorhexidine, and is extremely effective against gram-positive and gram-negative bacteria, fungi and yeasts. At this percentage, chlorhexidine is not irritating and not inactivated by organic substances such as pus and exudates, and the effects are long-lasting. Otodine also contains Tris-ethylene diamine tetra acetic acid, which has direct bactericidal action against some bacteria and works synergistically with chlorhexidine and topical antibiotics. Chen T, Hill PB. The biology of Malassezia organisms and their ability to induce immune responses and skin disease. Vet Dermatol. If your dog has extremely dirty ears, the instructions recommend applying 2-3 times daily over several days Silver Honey also makes pet wipes for surface cleaning of the outer ear and a 10-day ear infection treatment, so consider which is best for your individual dog’s needsDe aktiva substanserna är uppdelade i två separata behållare och ska blandas före användning. Tris-EDTA kommer i en flaska (Flaska A) och N-Acetylcystein kommer i en kork (Kork B). Contains witch hazel extract, tea tree oil, organic mullein leaf extract, rosemary extract, and fingerroot extract To increase client compliance with treatment, 1-mL syringes can be sent home with clients so that they can draw up the recommended amount of ear medication. Numerous commercially available ear products contain antibiotics or disinfectants with antibacterial activity ( TABLE 3 ). Common antibiotics are aminoglycosides (gentamicin, neomycin), fluoroquinolones (ciprofloxacin, enrofloxacin, marbofloxacin, orbifloxacin), polymyxins (colistin sulfate, polymyxin B), fusidic acid, florfenicol, and silver sulfadiazine. 8

This multi-symptom, natural formula is ideal for persistently itchy or smelly dog ears. It can also be used for dirty discharge caused by mites, bacteria, yeast, or fungal infections. “This product utilizes the power of herbs and natural therapeutics to help fight infections and reduce inflammation naturally rather than relying on stronger antifungals and antibiotics,” Woodley says.“Natural witch hazel extract helps dry out the ears and prevent potential ear infections. I recommend this product for prevention and even treating mild ear infections, especially if you’re looking for a natural ear cleaner.” Linkskin spray — This is a revolutionary topical approach to safely manage allergic dermatitis in all dogs and cats, including those weighing less than 3 kg. The spray can be used in combination with all pharmacological therapies during acute allergic flares to facilitate drug effectiveness. In addition, Linkskin spray can balance the skin’s microbiome and help prevent allergic flares. Active ingredients include:Step 4: After they’re done shaking, take a cotton ball or piece of gauze and gently wipe and dry their ear canal. Just be careful to not go too deep into their ear so you don’t hurt them and never use a Qtip or anything with a pointed end. CLX Derm 4% shampoo — This product contains 4% chlorhexidine, glycerine, and lanolin. Chlorhexidine at 4% has been shown to be effective against a wide range of pathogens that can lead to skin disease. Glycerine is an excellent chlorhexidine carrier and works synergistically with lanolin to soften and protect the skin. Tindallised lactobacilli — Beneficial bacterial cells counteract pathogenic bacteria from developing, and stimulate the pet’s immune system. Penetration of antibiotics with a low volume of distribution into ear tissues is limited. Fluoroquinolones have a high volume of distribution and penetrate well. However, these should be used at high dose in end-stage otitis externa and media (e.g., 10–20 mg/kg for enrofloxacin).

Topical therapy is preferred wherever possible. Systemic antimicrobial therapy may be less effective in erythroceruminous otitis externa as bacteria are present only in the external ear canal and cerumen. Systemic treatment may be more useful in suppurative otitis externa and/or otitis media where there is an inflammatory discharge with concurrent tissue infection. Systemic treatment is indicated when the ear canal cannot be treated topically (e.g., stenosis, compliance problems or topical adverse reactions) and in otitis media.Dirty, waxy ears are no fun for your dog and even less enjoyable if he requires a vet visit,” says Dr. Katie Woodley, holistic veterinarian of The Natural Pet Doctor. “Sure, you can make an apple cider vinegar concoction or use the Great Ears ready-to-use dog ear cleaner. It’s portable, gentle, convenient, and designed to gently remove ear wax, debris, and dirt from canine ears of any size or shape.” Tris NAC is designed with Tris EDTA and N-acetyl cysteine for managing bacterial ear and skin issues in dogs and cats that resist usual treatments.

Reducing pruritus, swelling, exudation and tissue proliferation is a key goal, and maintenance treatment is necessary in ongoing conditions (e.g., atopic dermatitis). Dexamethasone helps reverse the ototoxic effect of Pseudomonas. Systemic treatment is necessary in cases with severe ear canal stenosis, and/or generalized inflammatory skin disease. Step 1: Before you start, try to get your dog comfortable and calm. If they’re food motivated, Dr. Martin says, you might want to give them some treats. (Hint: peanut butter on a chew toy is often a great distraction.)High ionic strength as an effective support in the prevention of the formation of bacterial biofilms. Nearly all ear infections involve commensal (e.g., staphylococci and Malassezia) or environmental (e.g., Pseudomonas) opportunists. The vast majority are secondary to pre-existing inflammation, foreign bodies, obstruction or other primary problems. Ongoing inflammation leads to a cycle of recurrent infection and chronic inflammation leading to progressive pathological changes and end-stage otitis. The chronic inflammation makes each bout of infection harder to treat and repeated antimicrobial use may select for resistance. It] varies greatly depending on the dog and their predisposition to ear debris buildup and ear infections,” explains Richardson. “Many dogs may not need their ears cleaned very often at all—less than monthly—whereas others may need their ears cleaned once a week or even every few days.”
