ABSTRACT: This study was conducted in north-western Nigeria to investigate the role of cats and dogs as potential reservoirs of thermophilic Campylobacter species. Faecal samples were analysed from 104 cats and 141 dogs between March 2007 and March 2009. The samples were collected from animals in households, those presented to veterinary premises and feline colonies. Campylobacter spp. were isolated from 39 (27.7%) and 19 (18.3%) dogs and cats, respectively. There was no significant difference in isolation rate observed between dogs (27.7%) and cats (18.3%) and there was also no significance difference between younger and older dogs; 23.1% (young) compared to 30.3% (older) dogs, but a significant difference was seen between young (4.3%) and older (29.3%) cats. Campylobacter upsaliensis predominated in the isolates, accounting for 89.5% and 74.4% of the positive samples in cats and dogs, respectively, C. jejuni constituted 21.1% and 23.1% of the positive samples from cats and dogs, respectively. This finding is an indication that dogs and cats frequently shed thermophilic Campylobacter spp. which could be of public health importance. To establish the zoonotic significance of canine and feline Campylobacter, isolates need to be further characterised and compared. This is the first study on the prevalence of campylobacter in cats and dogs in the region.

ABSTRACT: This study was undertaken to determine the type and estimate the prevalence of bacterial organisms on contact surfaces of five close-to-patient facilities in three veterinary health care settings within the Sokoto metropolis of north-western Nigeria. A total of 30 samples (10 from each setting) were collected and analysed using culture, microscopy and biochemical testing. Bacterial species isolated from samples in this study included the following: Bacillus sp. (27.3%), Staphylococcus aureus (15.9%), Listeria sp. (13.6%), Streptococcus sp. (11.4%), Salmonella sp. (6.8%), Escherichia coli (4.5%), Staphylococcus epidermidis (4.5%), Citrobacter sp. (2.3%), Klebsiella sp. (2.3%), Lactobacillus sp. (2.3%), Micrococcus sp. (2.3%), Pasteurella sp. (2.3%), Proteus sp. (2.3%), and Yersinia sp. (2.3%). A higher percentage (64.3%) of the total bacterial isolates were zoonotic in nature and hence of public health significance. Some pathogens have the potential of nosocomial spread. In this study, we seek to establish the first evidence of bacterial presence in the major veterinary health care settings in the Sokoto region of north-western Nigeria. Of particular interest is the hypothesis, which has not previously been formally tested, that nosocomial infections are especially likely to be implicated in both animals and occupational diseases in Nigeria. It was suggested that some of these isolates were associated with the risk of nosocomial and zoonotic infections and hence draws attention to the need to rigorously employ standard veterinary precautions as part of the hospital's infection control programme in an attempt to protect both patients and staff from infections.

ABSTRACT: The prevalence of Campylobacter spp. in cattle in Sokoto State, Nigeria, was determined. The number of samples collected totalled 976, of which 126 (12.9%) yielded Campylobacter spp. The species of Campylobacter isolates from this study were as follows: C. jejuni (65.1%), C. coli (23.0%), C. lari (7.9%), C. hyointestinalis (3.2%) and C. fetus (0.8%). A total of 172 strains of Campylobacter spp. were identified from the positive samples due to identification of more than a single strain (spp.) from a single sample. The strains identified were C. jejuni (62.8%), C. coli (25.0%), C. lari (8.1%), C. hyointestinalis (2.9%) and C. fetus (1.2%). More than one species of Campylobacter was identified in 36.5% of the positive samples. The biotyping in this study revealed C. jejuni biotype I (34.3%) as the most common C. jejuni biotype, while C. jejuni biotype IV (15.7%) was the C. jejuni biotype that was least frequently isolated. However, the most frequently isolated C. coli biotype was biotype I (72.1%) and all the isolates of C. lari were biotype I.
