Prevalence of thermophilic Campylobacter species in cats and dogs in two animal shelters in Ireland

Rectal swabs or faecal samples for the isolation of Campylobacter species were taken from 120 dogs and cats in an animal shelter in which only one kitten showed signs of gastrointestinal disease, and rectal swabs were taken from 46 dogs, 22 of which showed signs of gastrointestinal disease, in another shelter. At the first shelter, the swabs from 24 of 47 dogs (51.1 per cent) and 36 of 48 cats (75 per cent) yielded a Campylobacter species. The rate of isolation was significantly higher from dogs and cats less than six months old, and significantly higher from cats than from dogs (P≤0·05). At the second shelter Campylobacter species were isolated from 40 of 46 dogs (87 per cent), but there was no significant difference between the age groups. Campylobacter species were isolated from 19 (86·4 per cent) of the 22 dogs with signs of gastrointestinal disease and from 21 (87·5 per cent) of the 24 unaffected dogs. Several culture methods were applied to the samples collected from both shelters, and the combination significantly increased the recovery of Campylobacter species.

Prevalence of thermophilic Campylobacter species in household cats and dogs in Ireland

Rectal swabs were collected from 147 household dogs and 35 household cats, including healthy animals, animals with gastrointestinal signs and animals with a variety of medical and surgical conditions. A combination of selective culture methods was used to optimise the recovery of Campylobacter species, and a PCR was used to confirm their isolation and to identify the species. The overall prevalence of Campylobacter species was 42·9 per cent in the cats and 41·5 per cent in the dogs. Campylobacter upsaliensis was the species most commonly isolated from the dogs and cats, and Campylobacter jejuni was the second most commonly isolated. Particularly high prevalences were detected in the few cats and dogs with diarrhoea, and in the cats and dogs that were six months old or younger.

Muscular dystrophy with truncated dystrophin in a family of Japanese Spitz dogs

Muscular dystrophy was diagnosed in seven male Japanese Spitz dogs with clinical signs of slowly progressive exercise intolerance, generalized weakness, myalgia, difficulty chewing and dysphagia. Serum creatine kinase (CK) concentrations were markedly elevated. Histopathology showed degeneration and regeneration of muscle, consistent with a dystrophic phenotype. Immunohistochemical staining for dystrophin and related proteins showed no staining with a monoclonal antibody against the rod domain of dystrophin but near-normal staining with an antibody against the C terminus. Immunoblot analysis in two affected dogs showed a truncated dystrophin protein of approximately 70-80 kDa. The severity of disease showed that this fragment was not large enough to protect from the dystrophic process.

Clinical signs, diagnosis and treatment of three dogs with angiostrongylosis in Ireland

Infection with Angiostrongylus vasorum was diagnosed at necropsy on a dog that died from acute pulmonary haemorrhage, and on recovery of L1 larvae by Baermann examination of faeces from two dogs, one of which had abdominal pain and retroperitoneal haemorrhage, while the other had right-sided heart failure due to cor pulmonale. The presenting signs included syncope (one dog), exercise intolerance (two dogs), cough (two dogs), abdominal pain (one dog) and depression (one dog). One-stage prothrombin time and activated partial thromboplastin time were prolonged in two dogs, buccal mucosal bleeding time was prolonged in one dog and globulin was elevated in all three dogs. Two dogs were treated with fenbendazole and recovered.

Domestic violence and the abuse of pets: Researching the link and its implications in Ireland

This paper reports on a small study which investigates the connection between domestic violence and non-accidental injury in animals in the Republic of Ireland. This found that many women reported witnessing one or more forms of abuse, or threats of abuse, of their pets. Most women considered that a place to accommodate pets would have made their decision to leave the family home easier. Four women disclosed that lack of such a service and concern for the welfare of their companion animals caused them to remain in their abusive relationships for longer than they felt appropriate. The majority of women felt unable to talk to anyone about their fears for their pets welfare and there is no service which can provide temporary accommodation for womens pets while they are in a refuge. These findings support those found elsewhere in larger studies in the US and UK, and demonstrate a high incidence of animal abuse in households where there is reported domestic violence. The implications for social work education and practice of the issue of violence against women are discussed.

Review of Feline Pancreatitis Part Two: Clinical Signs, Diagnosis and Treatment:

In the past decade pancreatitis has become recognised as a significant disease in the cat. Chronic, mild pancreatitis is often associated with more commonly diagnosed diseases such as inflammatory bowel disease or cholangitis/cholangiohepatitis. Furthermore, acute pancreatitis with similar complications to those seen in dogs is now diagnosed more frequently in cats. Unfortunately, the clinical signs and clinicopathological findings in cats with pancreatitis are often non-specific and vague. The lack of specific signs often results in a diagnosis being made only when the veterinary surgeon has a strong index of suspicion for pancreatitis and vigorously pursues that diagnosis. Pancreatitis is an important disease in cats, has been implicated as a potential cause of diabetes mellitus, and when present complicates the treatment of diabetes and other intra-abdominal diseases in cats.

A comparison of different culture methods for the recovery of Campylobacter species from pets.

Five culture methods for the recovery of Campylobacter species (spp.) were evaluated on 361 rectal swabs collected from cats and dogs in Ireland. Speciation using PCR methods was performed on all isolates to assess the sensitivity of each culture method for isolation of Campylobacter spp., and to establish the prevalence of Campylobacter jejuni, C. coli, C. upsaliensis, C. lari and C. helveticus. Overall 163 of 361 (45.2%) samples were confirmed Campylobacter spp. positive. Direct plating onto modified charcoal cefoperazone deoxycholate agar (mCCDA) with cefoperazone, amphotericin and teicoplanin (CAT) selective supplement yielded a significantly higher prevalence of Campylobacter spp. (33.0%) than each of the other four methods (Pu2003≤u20030.05). This method was also the most sensitive method for isolation of C. upsaliensis compared with any of the other four methods used in the current study (Pu2003≤u20030.05). A direct plating method onto mCCDA agar with CCDA selective supplement and a filtration method onto blood agar after pre‐enrichment in CAT supplemented broth yielded lower Campylobacter spp. prevalences of 19.7% and 17.5% respectively. A filtration method onto CAT agar and pre‐enrichment in Preston broth before plating onto mCCDA agar were less sensitive for the isolation of Campylobacter spp. Speciation results of Campylobacter isolates revealed the majority of Campylobacter isolates were C. upsaliensis (50.0%) and C. jejuni (41.9%). A small number of isolates were C. coli (2.6%), C. lari (1.5%) and C. helveticus (1.1%). The overall detection of Campylobacter spp. in the 361 pets sampled was significantly increased by using a combination of isolation methods (Pu2003≤u20030.05), producing a more accurate determination of the prevalence of Campylobacter spp. in pets in Ireland and of the actual Campylobacter species. As the majority of Campylobacter spp. were recovered by direct plating onto mCCDA agar with CAT supplement, this method is the method of choice if only a single method is selected for isolation of the most common Campylobacter spp. detected in pets and humans.

Characteristics of 234 dog bite incidents in Ireland during 2004 and 2005.

Information was obtained by telephone interview from 100 dog owners whose dog had bitten a person, and from 134 victims of bites by a dog not owned by the victim. Three-quarters of the victims were female and aged from 21 to 60 years. The majority of the dogs were owned, male, two to six years old, over 10 kg in bodyweight and belonged to the popular breeds: collies, cocker/springer spaniels, terrier breeds, Jack Russell terriers, German shepherd dogs, golden retrievers and crossbreeds. The numbers of bites by the different breeds indicated that those that inflicted the most bites were the popular breeds rather than the breeds with any greater propensity to bite. Most attacks were rapid single bites and in 50 per cent of the cases, neither the owner nor the victim was able to identify any signal of the dogs intention to bite. Overall, 21 per cent of the incidents were rated as ‘serious’ and 2 per cent as ‘life threatening’. One fifth of the dogs were euthanased as a result of the incident. Half the incidents required professional medical assistance for the victim. Almost half the incidents took place while the victim was walking or passing close to the dogs territory, or while the victim was interacting with the dog at home.

Animal abuse and intimate partner violence: researching the link and its significance in Ireland - a veterinary perspective

Research on domestic violence has established a substantial association between intimate partner abuse and the abuse of children within the home. It is only recently however, that researchers have demonstrated the correlation between non-accidental injury in animals, and abuse of women by their intimate male partners. A growing body of evidence suggests that animal abuse can be an early indicator for other forms of violent behaviour. This research includes the responses of a sample of 23 women using refuge services in the Republic of Ireland. It investigates the connection between domestic violence and animal abuse, and ascertains if there is sufficient support service for animals and people relevant to domestic abuse. In the survey population, 57% of women reported witnessing one or more forms of abuse, or threats of abuse, of their pets. Five of which were reported to have resulted in the death of the pet. Eighty seven per cent of women felt a facility to accommodate pets would have made their decision to leave the family home easier. Four women disclosed that lack of such a service and concern for the welfare of their companion animals caused them to remain in their abusive relationships for longer than they felt appropriate. Nine families placed pets in the care of family or friends, one woman is unaware of the fate of her pet, while the pets of six families remained with the abusive male after his partner entered a refuge. The majority of women felt unable to talk to anyone about their fears for their pets welfare. Many felt that there is no service which can provide temporary accommodation for womens pets while they are in refuge. The results obtained support those found elsewhere in larger studies in the USA and UK, and demonstrate an association of animal abuse in households where there is reported domestic violence.

Assessing the severity of canine pancreatitis

The objective of this study was to determine whether laboratory testing currently available is able to provide prognostic information in canine pancreatitis. A prospective study of dogs with naturally occurring pancreatitis was undertaken. Twenty-two cases with histologically confirmed pancreatic inflammation were included in the study. Each dog had routine haematology parameters, serum biochemistry (including lipase and amylase), serum trypsin-like immunoreactivity and trypsinogen activation peptides (TAP) in urine and plasma measured. Twelve of the dogs were classified as having severe disease. These dogs had statistically significant increases in urinary TAP-creatinine ratio (UTCR) measurement, serum lipase, serum phosphate and serum creatinine concentrations. Additionally dogs with severe pancreatitis had significantly decreased urine specific gravity levels. The most sensitive and specific test to assess the severity of pancreatitis was the measurement of UTCR.
