Histopathological Effect of Primextra Herbicide on some Organs of African Catfish (Clarias Gariepinus)

Histopathological Effect of Primextra Herbicide on some Organs of African Catfish (Clarias Gariepinus)

ABSTRACT

The toxicity of primextra (Chloroacetamide and atrazine) herbicide was investigated with emphasis on histopathological effects on some organs of African catfish (Clarias gariepinus) juvenile. The fishes were exposed to 0.00, 0.01, 0.04 and 0.08mg/l. Respiratory stress, erractic swimming, sudden quick movement, restlessness, weakness and settlement at the bottom were observed in exposed fish. These behavioural parameters varied with the concentration of the toxicant. Histopathology of the liver after 96hours exposure revealed hydropic swelling of hepatocytes and vacuolation. The kidney showed hydropic swelling of tubular cells, lipid vacuole accumulation in many tubules and nuclear pyknosis. Read More »

Distribution of Beta Hemolysin of Staphylococcus aureus amongst Clinical Samples

Distribution of Beta Hemolysin of Staphylococcus aureus amongst Clinical Samples in Major Hospitals in Abakaliki Metropolis

Abstract

Staphylococcus aureus is a major cause of bacterial infection in human. Serious infections associated with S. aureus are toxic shock syndrome, osteomylitis, invasive endocarditis, septic arthritis and septicemia. In this study, the indicative presence of S.aureus beta toxin were determined with an aim of ascertaining its possible distribution amongst clinical samples in the major hospitals in Abakaliki, Ebonyi State, Nigeria. Seventy (70) clinical specimens were subjected to cultural tests out of which forty (40) isolates were selectively obtained to be S. aureus. Out of these forty (40) isolates, sixteen (16) were hemolytic on sheep erythrocytes. Read More »

Comparative Analaysis of Resistance Pattern of Staphylococcus Aureus Isolated From Urine and Soft Tissue Infections

Comparative Analaysis of Resistance Pattern of Staphylococcus Aureus Isolated From Urine and Soft Tissue Infections

Introduction and Literature Review

Staphylococcus:Staphylococci are grain positive cocci, occurring singly, in pairs and in tetrads and characteristically dividing in more than one plane to forms irregular clusters.   The cell wall contains peptidoglycan and techoic acid. They grow readily on many types of media and are active metabolically, fermenting carbohydrates and producing pigments that vary form white to deep yellow. They are normally inhabitants of the upper expiratory tract, skin, intestine and vaginal. Staphylococci are member of a group of invasive gram positive bacteria known as the pyogenic (or pus producing) cocci (Tamsbekar and Khandelwal, 2005). Read More »
