Dengue fever regardless of its serotypes has been the most prevalent arthropod-borne viral diseases among the world population. The development of a dengue vaccine is complicated by the antibody-dependent enhancement effect. Thus, the development of a plant-based antiviral preparation promises a more potential alternative in combating dengue disease.

Fulltext Mass spectrometry-based identification and whole-genome characterisation of the first pteropine orthoreovirus isolated from monkey faeces in Thailand

Kosoltanapiwat N, Reamtong O, Okabayashi T, Ampawong S, Rungruengkitkun A, Thiangtrongjit T, et al.

BMC Microbiol, 2018 10 17;18(1):135.

PMID: 30332986 DOI: 10.1186/s12866-018-1302-9

BACKGROUND: The pteropine orthoreovirus (PRV) was isolated from monkey (Macaca fascicularis) faecal samples collected from human-inhabited areas in Lopburi Province, Thailand. These samples were initially obtained to survey for the presence of hepatitis E virus (HEV).

RESULTS: Two virus isolates were retrieved by virus culture of 55 monkey faecal samples. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was successfully used to identify the viruses as the segmented dsRNA orthoreovirus. Phylogenetic analysis of the Lopburi orthoreovirus whole-genomes revealed relationships with the well-characterised PRVs Pulau (segment L1), Cangyuan (segments L2, M3 and S3), Melaka (segments L3 and M2), Kampar (segments M1 and S2) and Sikamat (segments S1 and S4) of Southeast Asia and China with nucleotide sequence identities of 93.5-98.9%. RT-PCR showed that PRV was detected in 10.9% (6/55) and HEV was detected in 25.5% (14/55) of the monkey faecal samples.

CONCLUSIONS: PRV was isolated from monkey faeces for the first time in Thailand via viral culture and LC-MS/MS. The genetic diversity of the virus genome segments suggested a re-assortment within the PRV species group. The overall findings emphasise that monkey faeces can be sources of zoonotic viruses, including PRV and HEV, and suggest the need for active virus surveillance in areas of human and monkey co-habitation to prevent and control emerging zoonotic diseases in the future.

The PPARgamma coding region and its role in visceral obesity

Boon Yin K, Najimudin N, Muhammad TS

Biochem Biophys Res Commun, 2008 Jun 27;371(2):177-9.

PMID: 18413145 DOI: 10.1016/j.bbrc.2008.04.013

Peroxisome proliferator-activated receptor gamma (PPARgamma) is a ligand activated transcription factor, plays many essential roles of biological function in higher organisms. The PPARgamma is mainly expressed in adipose tissue. It regulates the transcriptional activity of genes by binding with other transcription factor. The PPARgamma coding region has been found to be closest to that of monkey in ours and other research groups. Thus, monkey is a more suitable animal model for future PPARgamma studying, although mice and rat are frequently being used. The PPARgamma is involved in regulating alterations of adipose tissue masses result from changes in mature adipocyte size and/or number through a complex interplay process called adipogenesis. However, the role of PPARgamma in negatively regulating the process of adipogenesis remains unclear. This review may help we investigate the differential expression of key transcription factor in adipose tissue in response to visceral obesity-induced diet in vivo. The study may also provide valuable information to define a more appropriate physiological condition in adipogenesis which may help to prevent diseases cause by negative regulation of the transcription factors in adipose tissue.

alpha1-Antitrypsin polymorphism in Malaysian Macaca irus

Kueppers F, Ganesan J

Biochem Genet, 1977 Oct;15(9-10):817-23.

PMID: 412492

alpha1-Antitrypsin types were determined in 200 individual specimens of Malaysian Macaca irus. We found the pattern B in 76 samples, BC in 116, and C in 8. Assuming that these patterns are determined by codominant alleles at one locus, this distribution constitutes a significant (P less than 0.001) deviation from Hardy-Weinberg equilibrium, because of an excess of BC and low prevalence of C. We found no clear evidence for the presence of alpha1-antitrypsin deficiency comparable to the situation in man.

Fulltext Outbreaks of monkeypox and serological surveys in nonhuman primates

Arita I, Gispen R, Kalter SS, Lim TH, Marennikova SS, Netter R, et al.

Bull World Health Organ, 1972;46(5):625-31.

PMID: 4340222

In connexion with the recent detection of cases of monkeypox in man in West and Central Africa, the frequency of monkeypox outbreaks in monkeys since 1958, when the disease was first recognized in captive animals, has been investigated. Special incidence surveys were made for this purpose. During the last 3 years, a serological survey has been conducted to find natural foci of monkeypox virus, and a total of 2 242 sera from monkeys of different species from various parts of Africa and Asia have been examined for poxvirus antibodies. The survey failed to detect any significant indication of poxvirus infections. The observations suggest that although a few human cases of monkeypox have been identified, monkeypox in the natural environment is not widespread and is perhaps localized in small areas.

Emerg Infect Dis, 2010 Nov;16(11):1783-5.

PMID: 21029545 DOI: 10.3201/eid1611.100721

Ancestral sylvatic dengue virus type 1, which was isolated from a monkey in 1972, was isolated from a patient with dengue fever in Malaysia. The virus is neutralized by serum of patients with endemic DENV-1 infection. Rare isolation of this virus suggests a limited spillover infection from an otherwise restricted sylvatic cycle.

Prevalence and etiology of linear enamel hypoplasia in monkeys and apes from Asia and Africa

Guatelli-Steinberg D, Skinner M

Folia Primatol., 2000 May-Jun;71(3):115-32.

PMID: 10828689

Ninety-seven specimens of sympatric monkeys and apes from East Malaysia and 115 monkeys and apes from West Africa are examined in order to evaluate the magnitude and nature of the great ape-monkey linear enamel hypoplasia (LEH) 'dichotomy'. This study demonstrates that great apes from both regions have a higher incidence of LEH and repetitive LEH than do gibbons and monkeys. However, the authors find that the dichotomy is not as clear-cut as previous research suggests, since some monkey samples exhibit high LEH frequencies. The authors evaluate the potential influence of great ape-monkey differences in crown height on this dichotomy. They show that canine crown height variation is weakly associated with LEH variation. Differences between monkeys and great apes in their crown formation spans and in their experience of environmental stress may be more likely causes of the dichotomy.

Multiplex PCR assay for the detection of five meat species forbidden in Islamic foods

Ali ME, Razzak MA, Hamid SB, Rahman MM, Amin MA, Rashid NR, et al.

Food Chem, 2015 Jun 15;177:214-24.

PMID: 25660879 DOI: 10.1016/j.foodchem.2014.12.098

Food falsification has direct impact on public health, religious faith, fair-trades and wildlife. For the first time, here we described a multiplex polymerase chain reaction assay for the accurate identification of five meat species forbidden in Islamic foods in a single assay platform. Five pairs of species-specific primers were designed targeting mitochondrial ND5, ATPase 6, and cytochrome b genes to amplify 172, 163, 141, 129 and 108 bp DNA fragments from cat, dog, pig, monkey and rat meats, respectively. All PCR products were identified in gel-images and electrochromatograms obtained from Experion Bioanalyzer. Species-specificity checking against 15 important meat and fish and 5 plant species detected no cross-species amplification. Screening of target species in model and commercial meatballs reflected its application to detect target species in process foods. The assay was tested to detect 0.01-0.02 ng DNA under raw states and 1% suspected meats in meatball formulation.

Plasmodium knowlesi - an emerging pathogen

Ahmed MA, Cox-Singh J

ISBT science series, 2015 Apr;10(Suppl 1):134-140.

PMID: 26029250

Ten years have passed since the publication of a large focus of Plasmodium knowlesi infections in the human population. The discovery was made during a molecular investigation of atypical P. malariae cases in the Kapit Health Division, Sarawak, Malaysian Borneo. Patients were more symptomatic with higher parasite counts than expected in P. malariae infections. The investigation found only P. knowlesi DNA present in patient blood samples. Morphological similarity had allowed P. knowlesi to masquerade as P. malariae during routine diagnostic microscopy for malaria. P. knowlesi, a malaria parasite of macaque monkeys, had entered the human population. The subsequent development of P. knowlesi species-specific PCR assays soon demonstrated that the entry was not confined to the Kapit Division but extended across island and mainland Southeast Asia. Relevant clinical descriptions and guidelines for the treatment and management of patents with P. knowlesi malaria were not available. Nor was it clear whether P. knowlesi had undergone a host switch event into the human population or if infections were zoonotic. The outputs of studies on P. knowlesi malaria during the past 10 years will be summarized, highlighting major findings within the context of pathophysiology, virulence, host switch events, treatment, control and importantly malaria elimination.

Fulltext Host specificity of Hepatocystis infection in short-nosed fruit bats (Cynopterus brachyotis) in Singapore

Low DHW, Hitch AT, Skiles MM, Borthwick SA, Neves ES, Lim ZX, et al.

Int J Parasitol Parasites Wildl, 2021 Aug;15:35-42.

PMID: 33948432 DOI: 10.1016/j.ijppaw.2021.04.001

Haemosporidians infect a wide diversity of bat genera and species, yet little is known about their transmission cycles or epidemiology. Though several recent studies have focused on the genus Hepatocystis, an Old World parasite primarily infecting bats, monkeys, and squirrels, this group is still understudied with little known about its transmission and molecular ecology. These parasites lack an asexual erythrocytic stage, making them unique from the Plasmodium vertebrate life cycle. In this study, we detected a prevalence of 31% of Hepatocystis in short-nosed fruit bats (Cynopterus brachyotis) in Singapore. Phylogenetic reconstruction with a partial cytochrome b sequence revealed a monophyletic group of Hepatocystis from C. brachyotis in Malaysia, Singapore, and Thailand. There was no relationship with infection and bat age, sex, location, body condition or monsoon season. The absence of this parasite in the five other bat species sampled in Singapore indicates this Hepatocystis species may be host restricted.
