Dermatophytosis is a common skin disease in cats and dogs caused by Microsporum and Trichophyton fungi. Species identification and knowledge of their antifungal susceptibility are therapeutically and epidemiologically important. This study assessed the prevalence of feline and canine dermatophytosis in Iran, identified the aetiological agents molecularly and tested their antifungal susceptibility. A total of 308 companion animals (134 dogs and 174 cats) with skin lesions were examined from March 2015 to March 2018. Hair and skin samples were examined by microscopy with 20% KOH and cultured on Sabouraud dextrose agar with cycloheximide and chloramphenicol. Fungal isolates were confirmed by sequencing of the internal transcribed spacer (ITS) r-DNA region. The antifungal susceptibility of dermatophytes was tested by broth microdilution assay using standard drugs. Dermatophytes were found in 130 (42.2%) samples, 62 of them feline and 68 canine. Based on sequencing of all strains, M. canis (78.5%, P<0.05), M. gypseum (10.7%), and T. mentagrophytes (10.7%) were the dermatophytes isolated. The non-dermatophyte species Nannizziopsis vriesii was also isolated from two feline dermatomycosis cases. Dogs and cats younger than one year (61.5%) showed a statistically significantly higher prevalence of infection (P<0.05). Caspofungin produced the lowest geometric mean MIC at 0.0018 μg/mL, followed by ketoconazole, terbinafine, itraconazole, miconazole, griseofulvin, clotrimazole and fluconazole, in a 0.038–1.53 μg/mL range. This is the first molecular study to identify the causes of pet dermatophytosis in north-western Iran. ITS-PCR was shown to be a useful and reliable method for the identification of closely related species of dermatophytes in clinical and epidemiological settings. The lowest MIC of caspofungin indicated that this drug was the most potent in vitro.

A study was carried out to detect and identify the presence of coccidia oocysts in the faeces of village chicken from the district of Pasir Putih, Kelantan, West Malaysia. A total of 135 fecal samples were collected from 15 areas in the Pasir PutihDistrict. The faecal samples were examined by direct smear method (qualitative study). A pinch of the faeces was put onto the glassslide with 1-2 drops of normal saline and cover slip, which was then observed under the compound microscope to detect thecoccidia oocysts. The presence of coccidia oocyst was then identified by its size and shape. Results showed that ten out of 135 samples were positive for coccidia oocysts, and classified as Eimeria maxima and Eimeria mitis, both of which are from two locations at Kampung Chap Banir, Pasir Putih, Kelantan. The remaining 125 samples were observed to be negative. This may suggest that the chickens reared in the backyard (extensive)are less susceptible to the coccidia infection due to their environment with lower stocking density (mostly free ranging chicken), and no damp/wet litter as bedding which canfacilitate sporulation of the coccicia oocyst thereby spreading the infection. Further studies need to be done to elucididate other factors which may affect coccidial infections in free range chicken such as the availability of medications in feed or genetic hardiness and tolerance to field infections. The localvillage chicken industry is an up and coming facet of the poultry industry and needs concerted efforts to boost it.

A survey of 95 wild rats which were captured from various locations was conducted to determine the diversity and distribution of ectoparasites and endoparasites infesting wild rat population around the city of Ipoh and Kuala Lumpur. The rodents captured were Rat tus norvegicus and post mortem was carried out immediately after capture, with skin and organs examined for parasite infection. Ectoparasites recovered were blood sucking louse (Polyplax spinulosa) and mites (Myocoptes musculinus). Endoparasites recovered were nematodes (Aspiculuris tetraptera, Trichuris sp., and two strongyles, one of which is Strongyloides sp.) And three intestinal protozoan parasites (Blastocystis sp., Trichomonas sp., and a coccidia). Low diversity of ecto- and endoparasites were observed infecting wild rat population caught in Ipoh as compared to Kuala Lumpur.

Data over a period of eleven years was analysed for Infectious Bursal Disease (IBD) virus isolated from chicken samples submit ted to the Regional Veterinary Laboratory at Bukit Tengah, Malaysia (RVLBT) for diagnosis. A total of 247 suspect IBD cases were tested by Virology Section, RVLBT between years of 2006 to 2016. IBD virus has been isolated by using Agar Gel Precipitation Test (AGPT), a bursal homogenate which has been used as an antigen against a known positive antiserum. About 27 cases (11%) from a total of 247 suspect cases in chickens were positive for the presence of IBD. The rate of IBD may be influenced by age of chickens with an increase in the possibility of IBD occurring in chicken older than 3 weeks. Apart from that, both broiler and local chickens are highly susceptible to this disease. Therefore, awareness on the existing IBD cases indicates the importance of strict management procedures, proper management programmes, vaccination and immunisation for chickens in Malaysia.

Objective-To determine the prevalence and temporal onset of lung lesions in lambs and the impact of lung lesions on growth of affected lambs. Animals-259 crossbred wether lambs from a single flock in the upper Midwestern United States. Procedure-An observational study was conducted. Lambs born in the spring and fall were slaughtered at finished weight or at a predetermined time point. Lungs of each lamb were examined and classified as normal, moderate lesions (consolidation > 5% but less than or equal to 50% of any lobe), or severe lesions (consolidation > 50% of any lobe). Data were examined to detect effects of prevalence or severity of lung lesions on growth and carcass traits. Results-57 of 89 (64%) spring-born lambs had lung lesions characterized by consolidation of lung tissue. A small number of lambs had pulmonary adhesions or active abscesses. In contrast, only 31 of 108 (29%) fall-born lambs had lung lesions. Severe lung lesions were associated with a significant reduction in average daily gain. Severe lung lesions were not detected until the middle of the finishing period and were associated with culture of Mannheimia haemolytica or Pasteurella multocida. Conclusions and Clinical Relevance-Analysis of results indicates that the prevalence of severe lung lesions can be quite high in lambs. Severe lung lesions can lead to greatly decreased growth performance of lambs.

In Zimbabwe, ocular squamous cell carcinoma (OSCC) was frequently observed in 5 breeding herds of Simmental cattle, a Bos taurus breed originating from Switzerland. In these herds, initial signs of OSCC were already noticeable in cattle about 3 years old. Gradually, OSCC prevalence increased, and 36 to 53% of cattle over 7 years old had 1 or more tumors. More tumors developed in Simmental cattle with periorbital white skin than in cattle with periorbital pigmented skin. Other breeds of cattle (eg, Friesian) also are partly white-faced and live in Zimbabwe in a comparable environment; yet, OSCC prevalence was lower in those breeds.

During the hunting season of 1992, 322 black bears from Pennsylvania were examined for Toxoplasma gondii- and Trichinella spp-induced infections. Toxoplasma gondii antibodies were found in 79.8% of 322 bears--titer < 1:25 in 65 (20.2%), 1:25 in 18 (5.6%), 1:50 in 11 (34.5%) and 1:500 in 128 (38.7%) bears--by use of the modified agglutination test. Muscle tissues from 89 of these bears were bioassayed for T gondii parasites. Muscles from 64 bears, including heart from 1 bear, and heart alone from another bear, were digested in pepsin, and the digested samples were bioassayed in mice. Toxoplasma gondii was isolated from 5 bears; from the heart of 1, heart and skeletal muscles of 1, and skeletal muscles of 3. The T gondii antibody titers for the 5 bears with detectable T gondii were: greater than or equal to 1:25 in all 5 bears by use of the modified agglutination test; < 1:10 (3 bears, considered Toxoplasma-negative), 1:20 and 1:320 by use of the Sabin-Feldman dye test; < 1:64 (3 bears, considered Toxoplasma-negative), 1:128, 1:512 by use of the indirect hemagglutination test, and < 1:16 (2 bears, considered Toxoplasma-negative), 1:32, 1:64, and 1:512 by use of the latex agglutination test. Toxoplasma gondii was not isolated from feces of 5 cats fed muscles from the remaining 25 bears with T gondii antibody titer < 1:25. Tissue cysts of the 4 T gondii isolates from bears were rendered noninfective by freezing at -13 C. Antibodies against Trichinella spp were found in 6 (1.8%) of 319 bear sera; Trichinella spp larvae were detected in muscle digests of 2 of 63 bears, and in histologic sections of muscles from 3 of 162 bears. Genetic typing indicated that the 2 Trichinella isolates from bears were a sylvatic genotype and were not the species found in domestic pigs.

Epidemiologic data were evaluated from all dogs admitted to the University of Minnesota, Veterinary Teaching Hospital (UMVTH) between June 1981 and November 1989. Of 69,890 admissions, 2,077 were Miniature Schnauzers. Uroliths were retrieved from 63 of the 2,077 Miniature Schnauzers admitted. In 20 of the 63 urolith episodes, calcium oxalate was the predominant mineral identified. By comparison, calcium oxalate uroliths were identified in only 56 of the remaining 67,813 non-Miniature Schnauzer canine admissions. The odds that uroliths from Miniature Schnauzers were composed of calcium oxalate was 11.8 times greater than for other canine breeds evaluated at the UMVTH (95% confidence interval = 6.8 to 20.1). Data also were evaluated from files of uroliths retrieved from dogs and submitted to the Minnesota Urolith Center for quantitative mineral analysis between June 1981 and November 1989. Of 3,930 uroliths analyzed, 615 (15.6%) uroliths were obtained from Miniature Schnauzers. Of the 615 uroliths, 175 (28.4%) were calcium oxalate. By comparison, only 550 (16.6%) of the remaining 3,315 from dogs of breeds other than Miniature Schnauzers were calcium oxalate. The odds that uroliths submitted for analysis were composed of calcium oxalate was 2 times greater for Miniature Schnauzers than for dogs of other breeds (95% confidence interval = 1.6 to 2.4). Calcium oxalate uroliths were retrieved more frequently in males than females. The risk for males developing calcium oxalate uroliths was > 3 times the risk for females in both groups of data evaluated. The mean age of all Miniature Schnauzers admitted to the UMVTH with calcium oxalate uroliths was 9 years. Calcium oxalate uroliths were not detected in Miniature Schnauzers younger than 1.7 years.

A total of 145,347 samples (4,322 cases) were received for the passive surveillance of melioidosis in the Serology Laboratory of Veterinary Research Institute (VRI) from the year 2012 to 2016. From the samples received, 0.63% were positive and 99.37% were negative. The objective of this study is to determine the seropositive rate and distribution of melioidosis in livestockbased on cases received which comprise of sheep (37.24%, n=54,130), goat (54.01%, n=78,500), cattle (8.12%, n=11,804) andbuffalo (0.63%, n=913) within the period of 5 years. A geographical mapping of seropositive cases was designed using thedata from the passive surveillance and the results were visualized in a geographical mapping which provides a clear visual description on the distribution of the diseases. By 2016, positive cases were found to be concentrated in the states on the east coast of Peninsular Malaysia and Sabah. To sum up, the percentage of seropositive cases of melioidosis in 5 years has increased from 1.79% in 2012 to 12.17% in 2015 and decreased to 1.04% in 2016. From the findings, this study can provide the dataneeded as the indicator for the evaluation of surveillance and vaccination programmes, disease eradication planning and to monitor the distribution of seropositive cases of melioidosis in Malaysia.

Salmonella is known as one of the important food-borne pathogenthat causes salmonellosis in human and animals worldwide. A prevalence study on salmonellosis was conducted on wild rats in Kelantan. From April to June 2015, a total of 36 rats and house shrews sent to the Regional Veterinary Laboratory in Kota Bharu, Kelantan were examined for the presence of Salmonella. These animalswere caught from various locations in the state and were sent to the laboratory either as live or dead specimens. Post mortem wasconducted and intestines were taken for detection of salmonellosis. Results showed that of the 32 rats and 4 shrews examined, 5 (15.6%) rats and 3 (75%) shrews were found positive and on serotyping fourserotypes of Salmonella were identified which are Salmonella ser. Kalamu (62.5%), Salmonella ser. Thyphimurium (12.5%), Salmonella ser. Weltevreden (12.5%) and Salmonella ser. Brancaster (12.5%). In conclusion, positive identification of Salmonella in wild rats indicates that there is a possible transmission of the pathogento humans due to constant contact between the two. Thus appropriate measures are needed to control these pests population to prevent spread of diseases to the humans and animals.
