There are many diseases that can be transmitted from animals to humans. These diseases are called zoonotic diseases. Although the list below is by no means comprehensive, some of the more common diseases that we can get from our household pets are:

• Ringworm, which is a fungal infection of the skin
• Hook worm, roundworm and tapeworm infection
• Toxoplasmosis
• Cat scratch disease
• Scabies, a mite that causes severe itchiness and skin lesions

In this article we are going to look at cat scratch disease (CSD), the cause of it, the symptoms and how to prevent it. Cat scratch disease, or cat scratch fever, is caused by an organism called Bartonella henselae or formerly called Rochalimaea henselae. It is a small anaerobic (organism which does not need oxygen to survive), gram-negative, non-motile bacterium. Domestic cats are the natural hosts for this organism and the animal from which humans can contract the disease (also known as the vector). If a cat harbors this bacterium, the cat very rarely shows any signs of the disease which is described as asymptomatic. It is therefore impossible to tell if a cat is infected with this organism without further testing. Fleas are the organism responsible for transmission of the disease between cats and therefore flea control is one of the best ways to prevent this disease. The infection rate is much higher in a population of cats that are flea ridden and can be as high as 61%. As a cat scratches and bites at fleas, the organism gets stuck between their teeth and under their nails. Kittens younger than 12 months are 15 times more likely to carry the infection than adult cats.

Many veterinarians are presented by concerned pet owners about the animal’s scooting or dragging their backsides along the ground by holding the back legs up in the air and pulling themselves forward by the front legs whilst remaining in a seated position. The owner often thinks that the animal may have worms and is trying to get the worms out their backside by dragging it along the ground. Although this is quite possible to be the case, especially in the case of tapeworm infestation, it is unlikely to be the cause. The most common cause for this behaviour is uncomfortable anal glands.

Fatal Diseases that can easily be prevented

There are some fairly common fatal diseases in animals which can and should be prevented wherever possible. This article looks at how these diseases present, what they lead to and most importantly how they could be prevented. Today we have more information about our animals and the diseases they may suffer from than ever before. With this knowledge comes the means of preventing these conditions that years ago would have meant certain death to our beloved pets. The most important means of disease prevention readily available to us is vaccination. A simple annual health check and vaccinations can help ensure your pet lives a long and healthy life. Other important means of prevention includes regular deworming as well as tick and flea treatment.

Introduction

Intervertebral disc disease is a term that describes the condition in which the softer cartilage like material in between the bones of the spine, called an intervertebral disc, pushes onto the spinal cord, causing clinical signs that varies from slight back pain and discomfort to complete paralysis of limbs. Even with the slightest clinical signs, your pet should be examined by the vet to establish how serious the condition is and be treated accordingly. The earlier this is attended to, the better the overall outcome. 

The prostate is the only accessory sex gland in the male dog. It is a butterfly shaped structure that surrounds the urethra (the tube that connects the bladder to the outside). Due to the location of the prostate, it can affect the urinary system, the colon and the hind legs, as well as having some systemic effects. Prostatic fluid is produced continuously in the dog. Prostatic fluid makes up most of the volume of seminal fluid (the fluid that carries semen). The prostate has many nerves and blood vessels running to it but is surrounded by a thick capsule, which sometimes makes it difficult for some drugs to get deep down into the prostate. Normal prostatic function is dependent on circulating testosterone. The prostate can develop a few conditions that can result in debilitating disease in the dog.

Introduction

Toxoplasma gondii is a tiny organism, slightly bigger than a bacterium, called a protozoa. This parasite has a worldwide distribution, except in the absence of cats. Cats are the only animals capable of completing the life cycle of this organism. Other warm blooded animals, including cats can serve as intermediate hosts for the parasite. The organism has a very high prevalence, but rarely causes clinical disease in dogs and cats. This is an important parasite to be aware of due to the fact that it is an important zoonosis, meaning it is an animal disease that can be transmitted to humans.

Feline infectious peritonitis (FIP) is a serious and most often fatal disease affecting cats. It is most commonly seen in young cats between the ages of six months and two years. It has been found to affect male cats more commonly than females and purebred cats particularly the Asian breeds are more susceptible. It is characterised by fluid build-up in body cavities such as the chest and abdomen and neurological signs. It can affect all major organs and inevitably results in death. It may be referred to as Feline coronavirus polyserositis (wet or effusive form) or granulomatous feline infectious peritonitis (dry or non effusive form).

Have you ever wondered if humans can get worms from dogs and cats? You don’t have to wonder any longer, the answer is ‘yes’.  In this overview we look at which worms can be transmitted between pets and humans, what diseases they cause and how to prevent this potential health risk.

Firstly when a disease or parasite can be transmitted from animals to humans it is called a zoonosis. It is often a concern when a pet is diagnosed with intestinal worms whether the family is at risk of contracting the parasite. The concern is valid but the good news is that it is easily managed with education, proper precautions and a well organised deworming program for your pets.

Bladder stones is a condition that occurs in dogs and cats of various ages, sex and breeds. Bladder stones are also called urinary calculi or uroliths. These are mineral like formations that form anywhere in the urinary tract, including kidneys, ureters, bladder and urethra. The most frequent location is the bladder. 

Clinical signs of bladder stones to look out for

Dogs with bladder stones often present like dogs with a bladder infection. Both of these conditions will show frequent urination as well as discomfort, particularly when urinating. The animal will squat to urinate frequently, often only passing small amounts of urine while straining. The owner might also see a red discoloration in the urine and in some cases the urine can be a dark red colour. Because the stones rub against the bladder wall it causes irritation and inflammation of the bladder wall that leads to bleeding. Some dogs will show discomfort and pain when walking, with the hindquarters tucked in, while cats can become very vocal when in pain. In some cases the stones may still be very small and can leave the bladder and enter the urethra. The urethra is the tube that directs urine from the bladder to the outside. If the stone is not small enough to pass, it will become lodged in the urethra, blocking urine flow completely. The pressure will build up in the bladder and the kidneys, and if this is not corrected quickly, the bladder can rupture. This will cause severe illness and if quick intervention is not done it may lead to death. 

Introduction

Feline leukaemia (FELV) is a disease of cats caused by a virus called a retrovirus. It is called a retrovirus because of the method it uses to replicate inside the cat. It is the same type of virus as the human immunodeficiency virus and although there are a lot of disease similarities, several studies have shown that the disease is not transmissible to humans. FeLV is one of the most dangerous diseases that affect cats and is a major cause of death in cats. Fortunately the prevalence of the disease has decreased in recent years due to the use of vaccines against the disease and the ability of vets to diagnose the disease early and accurately.
