Preliminary investigation into the ecology of marine viruses in Malaysia

Heng Pei Li, . and Lee Choon Weng, . (2011) Preliminary investigation into the ecology of marine viruses in Malaysia. [Proceedings Paper]

In this study we investigated the abundance of marine viruses in the coastal waters of Peninsular Malaysia. Virus counts were measured via epifluorescence microscopy. Samples were collected from Port Klang and Port Dickson where Port Klang was eutrophic and Port Dickson was oligotrophic. Three different preservation methods were used for our samples i.e. unpreserved preserved with formaldehyde and frozen without preservation Based on the counts obtained frozen samples consistently gave the lowest virus counts F13.65 q 7 28 P 0.005. The counts also differed significantly between both sites with higher counts at Port Klang which ranged from 6 68 x 10� to 5.45 x10�· cells/mL whereas at Port Dickson it ranged from 2 52 x 10� to 1.33 x 10�· cells/mL t-Test: t 2.07 df 22 P 0.01. When comparing with bacterial abundance and Chlorophyll a concentration the virus count was found to be significantly correlated only to Chlorophyll a concentration r 0.423 df 10 p 0.05.

Abstract

In this study we investigated the abundance of marine viruses in the coastal waters of Peninsular Malaysia. Virus counts were measured via epifluorescence microscopy. Samples were collected from Port Klang and Port Dickson where Port Klang was eutrophic and Port Dickson was oligotrophic. Three different preservation methods were used for our samples i.e. unpreserved preserved with formaldehyde and frozen without preservation Based on the counts obtained frozen samples consistently gave the lowest virus counts F13.65 q 7 28 P 0.005. The counts also differed significantly between both sites with higher counts at Port Klang which ranged from 6 68 x 10� to 5.45 x10�· cells/mL whereas at Port Dickson it ranged from 2 52 x 10� to 1.33 x 10�· cells/mL t-Test: t 2.07 df 22 P 0.01. When comparing with bacterial abundance and Chlorophyll a concentration the virus count was found to be significantly correlated only to Chlorophyll a concentration r 0.423 df 10 p 0.05.
