Introduction: Leptospirosis is endemic to tropical regions of
the world and is re-emerging as a new danger to public
health in Malaysia. the purpose of this particular study was
to determine the common leptospiral serovars present in
human communities living around wildlife
reserves/disturbed forest habitats. the objective of this
study was to estimate the seroprevalence of leptospirosis
and finding infecting serovars in villages surrounded
habitats where wildlife lives in Sarawak, Malaysia.
Methods: A cross-sectional serological survey of 198
humans was conducted in four villages around Kuching,
Sarawak between January 2011 and March 2012.
results: A seroprevalence of 35.9% (95%cI 29.2-43.0) to the
MAt was detected in the tested humans. Antibodies to
serovar Lepto 175 Sarawak were most commonly detected
(31.3%; 95%cI 24.9-38.3) and were detected in individuals at
all four locations. the presence of skin wounds (Or 3.1),
farm animals (Or 2.5) and rats (Or 11.2) were all
significantly associated with seropositivity in a multivariable
logistic regression model.
conclusions: the results of the current study are important
as wildlife may act as reservoirs of leptospires for humans.
Health authorities should expand disease control measures
to minimise the spill-over from wildlife to humans visiting,
living or working in the sampled locations. the pathogenic
status of serovar Lepto 175 Sarawak also requires further
investigation.

Introduction: ABO blood group can be associated with chronic diseases, for example, cancer and coronary heart
disease, however it is not proven in Type 2 Diabetes Mellitus (T2DM). The aim of this study was to identify the association between the ABO blood group and disease control among T2DM patients at Kepala Batas, Penang. Methods:
Approximately two mL vials of fresh blood were collected and typed using the tube method from 129 T2DM and 132
non-diabetic (control) patients, who visited the specialist clinic. The sociodemographic characteristics of the T2DM
patients was analysed using descriptive analysis. The proportions of A, B, AB, and O blood groups among the diabetic and control patients were compared using the chi-square test. Any association between the ABO blood group
and disease control was identified using the bivariate correlation test. Results: No significant association was found
between the ABO group and T2DM patients (p = 0.152) when compared with the control group. However, blood
group B was the most frequent among T2DM patients (33.3%) compared to blood group O within the control group
(36.4%). Negative associations were observed between the ABO blood group and BMI (r = 0.098, p = 0.268), as well
as the HbA1C value (r = -0.065, p = 0.464). Conclusion: No association was found between the ABO blood group
and the associated risk factors (BMI and HbA1C). However, individuals with blood group B and risk factors, such as
older age group, obesity, and high HbA1C value (more than 7.0%), should be monitored.
