    Trichuris trichiura (whipworm) are soil-transmitted helminths (STHs) that causing trichuriasis in human. Trichuris vulpis, a canine whipworm has also been reported occasionally in humans. However, an overlapping dimension in the morphology and due to limited external characters between both species may lead to the potential for misidentification. Although there has been an extensive study on the distribution of whipworm in both human and animal hosts, little is known about the molecular epidemiology of Trichuris species in both hosts. To investigate to characterize the whipworm species and to determine the genetic relationship between species infecting both humans and animals, we sequenced the small subunit ribosomal RNA (SSU rRNA) regions of Trichuris egg isolated from humans, dogs and cats in a rural community in Malaysia. A total of 524 fresh fecal samples were collected from humans and animals. The overall prevalence of Trichuris was 59.9% as determined by microscopy examination. The molecular analysis showed that 98.7% were identified as T. trichiura in the human fecal sample. Interestingly, 1.3% were identified as T. vulpis. As for animal fecal sample, 56.8% and 43.2% were identified as T. trichiura and T. vulpis, respectively. Phylogenetic and sequence analysis demonstrated that T. trichiura isolates were genetically distinct from T. vulpis isolates from both hosts. This finding implies that companion animals can be a reservoir and mechanical transmitter for T. trichiura infection in human and also highlighting the possible zoonotic potential of T. vulpis. This finding may also suggest that cross-transmission between humans and animal hosts in sympatric setting may be a source of infection in both hosts. More studies are needed to better understand the transmission dynamic and public health significance of Trichuris infection in both hosts.

    Feline anaplasmosis is considered as an emerging tick-borne disease of zoonotic potential. The aim of current study was to investigate the molecular prevalence of anaplasmosis, associated risk factors, and alterations in hematological parameters of domestic cats from Lahore, Pakistan. Blood samples of 100 domestic cats from district Lahore were examined microscopically and the extracted genomic DNA from each sample was processed for the amplification of 16 S rRNA gene of Anaplasma. PCR confirmed isolates were purified for sequencing. The data regarding the risk factors was collected in a predesigned questionnaire and statistically analyzed by logistic regression analysis. The study found a molecular prevalence of 13% (13/100) among analyzed blood samples. The nucleotide analysis of Anaplasmataceae species sequences amplified by PCR showed high resemblance (99%) with isolates from Korea, Japan, Malaysia, Philippines, and India. The potential risk factors found to be significantly associated (p

    Introduction: Acalypha indica is commonly referred to as “pokok kucing galak”. It is an herbaceous species that grow along the earth’s equator line, including the wet, temperate and tropical regions. Domestic cats experience the effect of this plant by reacting very favorably to the root. The first compilation of the ethnopharmacology and phytochemistry of the Acalypha plants was published. This genus is the fourth largest genus of the Euphorbiaceae family, with about 500 species. However, the review only represents about one third of the species from the Acalypha genus. Methods: Hence, this study is performed to obtain updates on the biochemistry of this plant, via literature search. Results: From the articles, almost every part of the plant, including the leaves, stems and roots, are used as traditional remedies. Local people consume the plant for therapeutic purposes such as anthelminthic, anti-ulcer, anti-bacteria, anti-microbial and wound healing. In homeopathy practice, it is used for asthma and bronchitis. Nevertheless,
    there is still a potential risk of using A. indica. It was reported that this traditional medicine could induce Intravascular haemolysis in patients with a glucose-6-phosphate-dehydrogenase (G6PD) deficiency. Clinical evaluations of Acalypha extract could be utilized to justify the ethnomedicinal claims and for the safety of its therapeutic applications. Meanwhile, there is an increase in the phytochemical and chromatographic experiments of A. indica that could introduce the extract’s role in pharmaceutical, nutraceutical, zoology and veterinary fields. It contains secondary metabolites, including dihydroactinidiolide; a terpenoid, alkaloids, flavonoids and steroids, for example, brassicasterol. Conclusion: The finding of this review concludes that Acalypha is a natural source, worth to be further investigated. It is hoped that new biologically active constituents could be discovered, since only few Acalypha species were comprehensively studied.

    Determination of feline meat in food products is an important issue for social, health, economic and religious concern. Hence this paper documented the application of species specific polymerase chain reaction-restriction fragment length polymorphism (SP-PCR-RFLP) assay targeting a short-fragments (69 bp) of mitochondrial cytochrome b (cytb) gene to screen feline meat in commercial meat products using lab-on-a-chip. The SP-PCR assay proved its specificity theoretically and experimentally while testing with different common animal, aquatic and plant species of DNA. The feline specific (69 bp, 43- and 26-bp) characteristic molecular DNA pattern was observed by SP-PCR and RFLP analysis. For assay performance, it was tested in three different types of commercial dummy meat products such as frankfurters, nuggets and meatballs and digested with AluI-restriction enzyme. The highest sensitivity of the assay using lab-on-a-chip was as low as 0.1 pg or 0.01 % (w/w) in commercial dummy meat products. We have also applied this assay to screen three important commercial meat products of six different brand from six supermarket chains located at three different states of Malaysia. Thus total 378 samples were tested to validate the specificity, sensitivity, stability of the assay and utilization of it for commercial meat product screening.

    PURPOSE: Toxoplasmosis is a zoonotic infection linked to compromised hygiene and sanitation via the handling of infected cat faeces, eating undercooked contaminated meat or transplacental transmission. We conducted a study to determine seroprevalence and risk factors associated with toxoplasmosis among the urban poor communities in Malaysia.

    METHODS: The demographic profiles for each participant were obtained through a questionnaire survey prior to blood collection. A total of 389 participants were recruited and blood samples screened for the presence of anti-Toxoplasma IgG and IgM antibody using an ELISA commercial kit, SERION ELISA classic Toxoplasma gondii IgG and IgM.

    RESULTS: The overall T. gondii seroprevalence was 69.6% with 56.8% seropositive for anti-Toxoplasma IgG, 7.7% seropositive for anti-Toxoplasma IgM and 5.1% seropositive for both IgG and IgM antibodies. The presence of both antibody classes in blood samples indicated high avidity, suggesting latent infection. Univariate analysis revealed significant associations that included; age, ethnicity, location and employment status while, significant lifestyle factors included source of drinking water and eating style. A multifactorial statistical model that incorporated all the significant effects from the first-stage univariate analyses listed above revealed that age and ethnicity were the two dominant and independent effects on IgG seroprevalence. For seroprevalence of IgM, the multifactorial model revealed a significant interaction between work and accommodation. IgM seroprevalence was higher among the unemployed inhabitants of PPR (Program Perumahan Rakyat) than those living in non-PPR accommodation, and higher than among the employed irrespective of their accommodation.

    CONCLUSION: High seroprevalence of Toxoplasmosis in the community calls for increased awareness of disease transmission and improvements in hygiene and sanitation.

    The life-cycle of Malaysian Spirometra spp. was studied under experimental conditions in the laboratory. The Cyclops were reared as the first intermediate host, the hamster as the experimental second intermediate host and cat as the definitive host. Maturation and hatching of eggs took 6 to 12 days by incubation at temperature 30 ºC. The hatched coracidium measured 46 x 34 μm. The Cyclops used were susceptible to the coracidial infection. The procercoid older than 5 days in the Cyclop body cavity had minute spines at the anterior end, calcium corpuscles in the body parenchyma and the cercomer at the posterior end. Procercoids 10 to 14 days old were infective to hamster. The plerocercoids from the hamster after 30 days were long and slender and were infective to cats. The plerocercoids experimentally inoculated to cats developed to adult worms and began to produce eggs between 10 to 60 days. Based on the results that have been obtained, a complete life-cycle was successfully elucidated in the laboratory and hamster was identified to be a good laboratory model for a second intermediate host of Spirometra sp.

    Toxoplasma gondii, a zoonotic protozoan that has a worldwide distribution, is known to infect many warm-blooded vertebrates. The feline species including domestic cats are the definitive hosts for Toxoplama gondii and shed the infective oocyst. There is lack of information on the prevalence of Toxoplasma gondii in cats in Malaysia. The objective of this study was to determine both the seroprevalence of T. gondii and the prevalence of T. gondii DNA in cats' feces in Klang Valley, Malaysia. 198 blood and 201 fecal samples were collected from pet and stray cats from the local council, Dewan Bandaraya Kuala Lumpur (DBKL) and University Veterinary Hospital, Universiti Putra Malaysia respectively. The overall seroprevalence of Toxoplasma gondii in cats in the Klang Valley was found to be 5.5%. There was a high prevalence (10.5%) of T. gondii DNA detected in the cat fecal samples in both pet and stray cats suggestive of T. gondii oocyst shedding. Stray cats showed a higher seroprevalence and molecular prevalence of T. gondii than the pet cats. However, comparative analysis using Chi-square test showed no significant difference between both groups (P>0.05). Higher prevalence (10.5%) of cats shedding T. gondii DNA as compared to the seroprevalence (5.5%) was found in the cat population in the Klang Valley. The high prevalence of cats shedding T. gondii DNA is alarming as this may directly reflect the number of oocysts excreted into the environment posing a significant public health hazard.

    Background. Ocular bartonellosis can present in various ways, with variable visual outcome. There is limited data on ocular bartonellosis in Malaysia. Objective. We aim to describe the clinical presentation and visual outcome of ocular bartonellosis in Malaysia. Materials and Methods. This was a retrospective review of patients treated for ocular bartonellosis in two ophthalmology centers in Malaysia between January 2013 and December 2015. The diagnosis was based on clinical features, supported by a positive Bartonella spp. serology. Results. Of the 19 patients in our series, females were predominant (63.2%). The mean age was 29.3 years. The majority (63.2%) had unilateral involvement. Five patients (26.3%) had a history of contact with cats. Neuroretinitis was the most common presentation (62.5%). Azithromycin was the antibiotic of choice (42.1%). Concurrent systemic corticosteroids were used in approximately 60% of cases. The presenting visual acuity was worse than 6/18 in approximately 60% of eyes; on final review, 76.9% of eyes had a visual acuity better than 6/18. Conclusion. Ocular bartonellosis tends to present with neuroretinitis. Azithromycin is a viable option for treatment. Systemic corticosteroids may be considered in those with poor visual acuity on presentation.

    There has been little change since 1955 in the laboratory techniques for seeking new antifilarial compounds, although one valuable addition to laboratory study has been the experimental infection of cats with Brugia malayi.The chief drug for the treatment and control of filariasis-whether caused by Wuchereria bancrofti or by B. malayi-continues to be diethylcarbamazine, and the author reviews the reports recently published on its use. In India and China large-scale campaigns involving the use of this drug have been undertaken; and in Tahiti filariasis has been suppressed and almost eliminated. Campaigns on a smaller scale and pilot projects considered in this survey include those conducted in Pacific islands, Malaya, Ceylon, Brazil, Surinam and East and West Africa.It is generally agreed that the administration of diethylcarbamazine produces a great diminution in the microfilarial counts of those taking it, and in many persons both microfilariae and adult worms are eradicated. The difficulties which arise are due to toxic effects which occur in some recipients and which may adversely affect the acceptability of treatment.

    Light and electron microscopic studies and feeding experiments have confirmed the presence of two species of Sarcocystis in the water buffalo Bubalus bubalis. One is the already known species with large macroscopic sarcocysts, Sarcocystis fusiformia (Railliet, 1897) Bernard and Bauche, 1912 and the other is S. levinei n. sp. which is being described in detail. The sarcocysts of S. levinei are 0.9 x 0.1 mm and the zoites in them 17.8 x 4.2 micrometer. Ultrastructurally, the primary cyst wall shows sloping villi with irregular wavy outlines. Within the villi are coarse granules and annulated fibrils. Trabeculae are present. The sexual stages of S. levinei occur in the subepithelial tissue of the small intestine of the dog and sporocysts shed by this definitive host are 15-16 by 10 micrometer.

    A 6-year-old intact Persian cat was presented for the primary complaint of inappetence and weight loss. Irregular surface of
    kidneys was palpated during physical examination. Abdominal radiograph findings were indicative of renomegaly. Ultrasonography
    revealed multiple anaechoic structures within the renal parenchyma. The cortex, medulla and renal pelvis were unable to be
    differentiated. Both radiographic and ultrasonographic findings were suggestive of polycystic kidney disease. Blood test revealed
    normochromic, normocytic anaemia with azotaemia whereas urinalysis findings were hypostenuria and proteinuria, consistent of
    chronic kidney disease due to polycystic kidney. Ultrasound is a useful antemortem diagnostic tool to diagnose polycystic kidney
    disease in cats.

    Oesophageal strictures associated with doxycycline therapy in cats are a rare occurrence but several cases have been reported. A 3-month-old kitten was presented to University Veterinary Hospital, Universiti Putra Malaysia (UVH-UPM) with the primary complaint of persistent vomiting. The kitten was prescribed with doxycycline two weeks prior to presentation. Regurgitation was observed during hospitalisation. Radiographs and endoscopy performed revealed findings consistent with a megaesophagus cranial to an oesophageal stricture located at the region of the second thoracic vertebrae.

    Background. The bay cat Catopuma badia is endemic to Borneo, whereas its sister species the Asian golden cat Catopuma temminckii is distributed from the Himalayas and southern China through Indochina, Peninsular Malaysia and Sumatra. Based on morphological data, up to five subspecies of the Asian golden cat have been recognized, but a taxonomic assessment, including molecular data and morphological characters, is still lacking. Results. We combined molecular data (whole mitochondrial genomes), morphological data (pelage) and species distribution projections (up to the Late Pleistocene) to infer how environmental changes may have influenced the distribution of these sister species over the past 120 000 years. The molecular analysis was based on sequenced mitogenomes of 3 bay cats and 40 Asian golden cats derived mainly from archival samples. Our molecular data suggested a time of split between the two species approximately 3.16 Ma and revealed very low nucleotide diversity within the Asian golden cat population, which supports recent expansion of the population. Discussion. The low nucleotide diversity suggested a population bottleneck in the Asian golden cat, possibly caused by the eruption of the Toba volcano in Northern Sumatra (approx. 74 kya), followed by a continuous population expansion in the Late Pleistocene/Early Holocene. Species distribution projections, the reconstruction of the demographic history, a genetic isolation-by-distance pattern and a gradual variation of pelage pattern support the hypothesis of a post-Toba population expansion of the Asian golden cat from south China/Indochina to Peninsular Malaysia and Sumatra. Our findings reject the current classification of five subspecies for the Asian golden cat, but instead support either a monotypic species or one comprising two subspecies: (i) the Sunda golden cat, distributed south of the Isthmus of Kra: C. t. temminckii and (ii) Indochinese, Indian, Himalayan and Chinese golden cats, occurring north of the Isthmus: C. t. moormensis.

    Background and Aim: Channa striatus extract, a freshwater snakehead fish known as Haruan, is popular in Southeast Asia for consumption and as a traditional therapeutic remedy for wound healing. C. striatus is also used in osteoarthritic for its anti-inflammatory. The aim of this study was to determine the presence of antibacterial properties of C. striatus extract against oral bacteria and to investigate the cytotoxic activity against Vero cells.

    Materials and Methods: The authors prepared C. striatus extract in chloroform-methanol solvents. Next, the authors took subgingival microbiological samples from 16 cats that had periodontal disease. The authors determined the antibacterial properties of C. striatus extract against the isolated bacteria using the disk diffusion method and a broth microdilution-based resazurin microtiter assay. Finally, the authors used the Vero cell line to evaluate the cytotoxic activity, and they assessed the cell availability using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay.

    Results: The results showed weak antibacterial activity of C. striatus extract against Pseudomonas spp. and Escherichia coli. In addition, the authors found that minimum inhibition concentration values ranged between 400 and 500 mg/mL, and minimum bactericidal concentration values ranged between 650 and 550 mg/mL. However, the cytotoxic results were promising, showing that C. striatus extract increased the cell viability and growth when it was at a higher concentration. The extract also promotes growth and cell proliferation.

    Conclusion: These findings suggest that C. striatus extract promoted cell proliferation in vitro and could be a plausible therapeutic wound healing alternative for periodontal disease in cats.

    Acanthamoeba species are ubiquitous free-living protozoa that can be found worldwide. Occasionally, it can become parasitic and the causative agent of acanthamoebic keratitis (AK) and Granulomatous Amoebic Encephalitis (GAE) in man. A total of 160 environmental samples and 225 naturally-infected animal corneal swabs were collected for Acanthamoeba cultivation. Acanthamoeba was found to be high in samples collected from environments (85%, 136/160) compared to infected animal corneas (24.89%, 56/225) by microscopic examination. Analysis of nucleotide sequence of 18S rRNA gene of all the 192 cultivable Acanthamoeba isolates revealed 4 genotypes (T3, T4. T5 and T15) with T4 as the most prevalent (69.27%, 133/192) followed by T5 (20.31%), T15 (9.90%) and T3 (0.52%). Genotype T4 was from the strain of A. castellanii U07401 (44.27%), A. castellanii U07409 (20.83%) and A. polyphagaAY026243 (4.17%), but interestingly, only A. castellanii U07401 was detected in naturally infected corneal samples. In environmental samples, T4 was commonly detected in all samples including dry soil, dust, wet debris, wet soil and water. Among the T4, A. castellanii (U07409) strains were detected high occurrence in dry (45%) followed by aquatic (32.50%) and moist (22.50%) samples but however A. castellanii (U07401) strains were dominant in dry samples of soil and dust (93.10%). Subsequently, genotype T5 of A. lenticulata (U94741) strains were dominant in samples collected from aquatic environments (58.97%). In summary, A. castellanii (U07401) strains were found dominant in both environmental and corneal swab samples. Therefore, these strains are possibly the most virulent and dry soil or dusts are the most possible source of Acanthamoeba infection in cats and dogs corneas.

    We conducted an exploratory serological survey to evaluate the exposure of Bornean wild carnivores to several viruses common to domestic felids, at interface areas between protected forest and industrial agriculture in the Kinabatangan floodplain (Sabah, Malaysia). Blood samples, collected from wild carnivores (n = 21) and domestic cats (n = 27), were tested for antibodies against feline coronavirus (FCoV), feline panleukopenia virus (FPLV), feline herpesvirus (FHV) and feline calicivirus (FCV), using commercial enzyme-linked immunosorbent assay (ELISA) test kits. Anti-FCoV antibodies were detected in most species, including one flat-headed cat (Prionailurus planiceps, [1/2]), leopard cats (Prionailurus bengalensis, [2/5]), Malay civets (Viverra tangalunga, [2/11]) and domestic cats (Felis catus, [2/27]). Anti-FCV antibodies were present in all domestic cats and one flat-headed cat, while anti-FPLV antibodies were identified in Sunda clouded leopards (Neofelis diardi, [2/2]), domestic cats [12/27] and Malay civets [2/11]. Anti-FHV antibodies were only detected in domestic cats [2/27]. Our findings indicate pathogen transmission risk between domestic and wild carnivore populations at the domestic animal-wildlife interface, emphasizing the concern for wildlife conservation for several endangered wild carnivores living in the area. Special consideration should be given to species that benefit from their association with humans and have the potential to carry pathogens between forest and plantations (e.g., Malay civets and leopard cats). Risk reduction strategies should be incorporated and supported as part of conservation actions in human-dominated landscapes.
